Telescoping gear
Structure of the chapter
Most procedures which you initiate for the operation of the telescoping gear are afterwards carried out by the crane control and monitored. In the process you receive acknowledgements, you can follow the procedure and, at the right time, initiate further procedures. For this it is important that you are not only familiar with the operation, display, and control instruments of the telescoping gear, but also its functioning. Then you can comprehend the procedures which the crane control carries out in the boom while you move the control lever; you will become familiar with the status displays and crane control more quickly. Therefore the chapter is organized in the following sections: – – – – –
Description of functioning, Main boom fixed lengths, intermediate lengths, telescoping lengths, Telescope status, Notes on telescope-sequence, Function of the control lever,
– Example of procedures when telescoping (further sections are refered to in this section).
H
The last section and the sections following it belong together and describe the actual telescoping procedure. Before you proceed according to this section for the first time, you must know the basic information from the previous sections. Only in this manner is a safe operation of the telescoping gear possible.
TRAINING INSTITUTE
Description of functioning
The main boom consists of the non-telescoping section, five telescope sections and a single-level telescoping cylinder. The following diagram shows the main boom in section with the telescoping cylinder.
In the diagram the main boom is completely retracted and the telescoping cylinder is located in the foot section of telescope section I. All telescope sections (I to V) are rigged on the outside with locking pins (1) which are pushed out of the telescope sections with springs (9). If a bore (2) of the telescope section above it aligns with the corresponding locking pin, the spring pushes the locking pin in at that point and the telescope section is locked. All telescope sections can be locked at three different points (on the fixed lengths) in the corresponding bores (2). Levers are fixed to the locking pins of all telescope sections of which the brackets (6) reach inward into the foot sections of the telescope section. The brackets reach in all telescope sections the same distance into the foot sections. The piston rod (7) of the telescoping cylinder is fastened to the main boom basic section. If the telescoping cylinder is telescoped, its head runs (8) through the foot sections of telescope sections (I to V). If the head (8) is situated at a locking point (the head is situated at the locking point of telescope section I), the mechanism (3) on the telescope cylinder snaps into the bracket (6). If the telescoping cylinder is located on the locking point, the bores (4) also align on the inner sides of the telescope sections with the locking pins (5) of the telescoping cylinder.
TRAINING INSTITUTE
Telescoping cylinders and telescope sections can be locked and unlocked at all locking points. In order to telescope, the telescoping cylinder must be locked with the corresponding telescope section and the telescope section must be unlocked. To lock the telescoping cylinder, the locking pins are (5) pushed into the bores (4) of the telescope section by spring force. In order to unlock the telescope section, a hydraulic cylinder (2) is extended. The mechanism (3) transfers this movement to the brackets (6) and retracts the locking pins (1) against the spring force. The telescope section is locked again after telescoping, the procedure takes place in the reversed sequence (as with unlocking). When the telescoping cylinder is unlocked, the locking pins are hydraulically retracted against the spring force.
H H Main boom fixed length, intermediate length, telescoping length
The locking pin of the telescoping cylinder and the mechanism are moved hydraulically. The necessary pressure for this is comes from a reservoir which must be first be filled. Because of this, retardations of 2 to 3 seconds may occur. A hydraulic/mechanical switch and the crane control prevent a telescope section and the telescoping cylinder from being unlocked simultaneously. A telescope section can be unlocked only when the telescoping cylinder is locked and vice versa.
Main boom fixed length All telescoping statuses where all telescope sections are locked are usually called main boom fixed lengths. Higher load bearing capacities are permitted only when all telescope sections are locked. In the case of the GMK 5180, only those telescoping status with the highest lifting capacities are permitted as main boom fixed lengths because of the large number of possible locked telescoping statuses for the same boom length. There are thus a total of 32 main boom fixed lengths (➠ Lifting capacity table). The lifting capacity values for the fixed lengths of the main boom are automatically monitored by the SLI.
TRAINING INSTITUTE
Main boom intermediate length All telescoping statuses where all telescope sections are unlocked are usually called main boom intermediate lengths. In an unlocked telescoping status the whole load affects the telescoping cylinder. This means that the permitted lifting capacitues are sometimes considerably less than with main boom fixed lengths. In the case of the GMK 5180, all locked telescoping statuses which do not have the highest load bearing capacity with their main boom length are also treated as main boom intermediate lengths. No higher loads are therefore permitted for these locked telescoping statuses. The lifting capacity values for the intermediate lengths of the main boom are automatically monitored by the SLI. Telescope the main boom to the required length before lifting the load! With the lifting capacities which are given in the lifting capacity table for main boom intermediate lengths, telescoping with a load is not possible! Main boom telescoping length There is a main boom telescoping length when the main boom is at a main boom intermediate length and is also telescoped with a load. The lifting capacity values for the telescoping length of the main boom are in the same range as the lifting capacity values for the main boom intermediate lengths which are monitored by the SLI. The SLI does not, however, monitor the capability of a load to be telescoped. The telescopic load is restricted by: – the angle of the boom and – the lubrication of the sliding wear pad between the telescope sections.
S Telescope status
The main boom should only be telescoped with a load if the job cannot be done otherwise.
The position of the telescope sections, i.e. which telescope section has been telescoped how far, is called the telescope status. The current telescope status is displayed: – on the SLI and – on the Crane control display.
TRAINING INSTITUTE
This section deals with the status display of the telescope status on the SLI, the status display of the telescope status on the Crane control display is described starting at the section Example of procedures when telescoping. If a telescope section is retracted or extended, both the length of the main boom and the length of the respective telescope section change on the display.
H
The main boom fixed length is displayed in decimals (e. g. 0.5) and the main boom intermediate length and main boom telescoping length are displayed as two-digit percent values (e. g. 47). Intermediate lengths and telescoping lengths at 100% are indicated by the flashing display 1.0. Example: Telescope status display for main boom fixed lengths

Not all locked telescope statuses are permitted as main boom fixed lengths; The fixed lengths can be found in the Lifting capacity table.
TRAINING INSTITUTE
The decimal display (e.g. 1.00) follows only if all telescope sections are telescoped to a fixed length. As soon as one or more telescope sections are telescoped to a different length, all lengths count as main boom intermediate lengths or main boom telescoping lengths. The status display changes accordingly, as the following example demonstrates. Example: Telescope status display for main boom intermediate lengths and main boom telescoping lengths.

There can only ever be one telescope section at an intermediate length (because only one telescope section can be unlocked). The useful intermediate lengths can be found in the Lifting capacity table. The maximum permissible lifting capacity also changes constantly in the Maximum load status display. Whenever the extending of a telescope section would lead to a telescope status which is not permissible according to the Lifting capacity table, the SLI switches this extending off as soon as the telescope section moves.
TRAINING INSTITUTE
Notes on telescopesequence
The telescope sections can only be telescoped individually one after the other. When extending you must always extend the telescope section with the highest numbering first, then the telescope section with the second highest numbering, etc. (e. g. V, IV, III, II, I). Retracting always takes place in the reversed sequence as extending.
Check before telescoping for the first time
The crane control calculates the displayed telescope status from the current status of the telescoping gear and the locking and unlocking processes which have occurred and been saved. Normally, the crane control recognises differences between current and displayed telescope statuses and displays a corresponding error message; If the values are deleted because of an accident (e.g. lightning strike), the crane control can no longer calculate the current telescoping status and an error message occurs.
S
Risk of damaging the telescoping gear! After switching on the ignition before the first telescoping, always check that the current telescope status is displayed in the crane control display. After an accident, if the crane control is unable to correctly calculate the current telescope status and no error message occurs, telescoping can cause damage to the telescoping gear.
• After switching on the ignition, always check before the first telescoping that the telescope status displayed in the crane control display matches the current telecope status. If the current telescope status is not correctly displayed, enter the current telescope status;
TRAINING INSTITUTE
Function of the control lever
This section only describes the functioning of the control lever and has general notes for telescoping. Before you telescope, you must fulfill certain requirements. Read the section Example of procedures when telescoping for this; The SLI deactivates telescoping extension depending on the size of the load and length of the main boom (angle between the main boom and the horizontal position). Ensure that the boom has been sufficiently raised before the main boom telescoping is extended.
Ö
• Switch on the telescoping gear. Push the Auxiliary hoist shutdown rocker switch upward.
_
• Switch the right hand control lever to the telescopic function. To do this press the Preselection of derricking control lever function / telescoping/derrick lattice extension rocker switch up.
T
The indicator lamp Telescoping gear switched on illuminates.
G H
Risk of accidents from unexpected crane movement! Make sure that the indicator lamp Telescoping gear switched on illuminates before you move the control lever for telescoping. This prevents accidents from the unexpected derricking of the main boom and lattice extension.
Extend:
Push the right-hand control lever to the right.
Retract:
Push the right-hand control lever to the left.
With certain telescoping states the SLI also shuts down the retraction of the telescoping for safety reasons. In this case leave the shutdown area by raising the boom or, if this is not possible, set the load down, telescope to the next fixed length and lift the load again. You may regulate the telescoping speed by moving the control lever and changing the engine speed using the accelerator.
@
You can set the maximum speed of the telescoping gear for working with the main boom and lattice extension on the Crane control display;
TRAINING INSTITUTE
In addition you can set a higher speed when extending by using the footoperated switch Fast speed derricking gear/telescoping gear (arrow).
å Ö
H S H >
You may set a constant engine speed using the rocker switch Constant engine speed. The telescoping gear can be switched off by rocker switch (Telescoping gear shutdown) to prevent it from being operated accidentally. To do this, press the rocker switch downward. The distance between the hook block and the boom head also changes during telescoping. Reel off the hoist rope when retracting and reel it on when extending the telescoping. Be careful not to damage the hoist rope! Slack rope will occur if the hook block is allowed to touch the ground while the boom is being retracted. This causes rope loops to form on the hoist drum which can lead to load slipping and damage to the hoist rope.
The telescoping movement is shut off if the hook block reaches the lifting limit switch during extension of the main boom telescoping.
You can display the operating hours and possibly the blocked functions of the telescoping gear on the crane control display with the membrane switch Display status;
TRAINING INSTITUTE
Example of procedures when telescoping
H
The procedures for telescoping with semi-automatic control are described in the following sections. You can also telescope to fixed lengths with the fully automatic control; in the course of this the crane control regulates the procedures described here automatically; This section shows you the sequence of an entire telescoping procedure for a better overview at the outset. This section and the sections refered to here presuppose that you are familiar with the functioning of the telescope system;
The entire example cannot apply to all telescoping procedures, since the start and end position of the telescoping gear is different for every procedure. Nevertheless a part of the sequence of the telescoping procedure described here applies to all telescoping procedures. Read the sequence for this example and follow the cross-references in the sections with the descriptions of what to do. These sections always take up the following example at the end. You thus get an overview of all necessary steps and can implement these for your special telescoping procedure. The following start and end states apply to this example: – – – –
All telescopic sections are retracted and locked. The telescoping cylinder is locked to telescope section IV. The telescope sections II and III should be extended to 50 %. Telescope section I should be extended to an intermediate length of 37 %.
Sequence of the exemplary telescoping procedure 1. Check the telescope status, the position of the telescoping cylinder and the locking pin; 2. Unlock telescoping cylinder;
TRAINING INSTITUTE
3. Move telescoping cylinder into the telescope section, the telescope section which needs to be telescoped and lock it there (in our example telescope section III);
4. Unlock telescope section for telescoping;
5. Telescope telescope section to fixed length and lock;
6. To telescope other telescope sections (in our example telescope section II would be the next one) repeat Points 2 to 5 until all required telescope sections have been telescoped to the required length. 7. If necessary, extend the last telescope section (in our example telescope section I) to the necessary intermediate length;
Check initial position
Before you telescope the main boom, you must check the following states: – the current telescope status (how far the telescope sections are telescoped), – the position of the telescoping cylinder (in which foot section the telescoping cylinder is located), – the position of the locking pins (whether telescope sections and cylinders are locked or unlocked). Various displays on the front instrument panel define the current status of the main boom.

If a telescope section is unlocked (e.g., Telescope section III), the respective numerical value is in brackets in the second line. Below, next to the entry TELE, the unlocked telescope section is displayed (T1 to T5 for telescope sections I to V). To the right is the current telescope status as a percentage (e.g., 0%).
Special case: If telescope section V is unlocked, only the left-hand bracket) is displayed, due to lack of space.
In our example, the display would indicate the start position as it appears in the first illustration. The main boom is completely retracted; therefore the display shows 0 (%) for all telescope sections. At the bottom left there are two dashes, and the current extended length of the telescoping cylinder is L: approx. 3.6 feet, since the head of the telescoping cylinder is extended into the foot section of telescope section IV.
TRAINING INSTITUTE
Checking the position of the telescoping cylinder The current telescope status is now known; the next thing you should do is check in which telescope section the head of the telescoping cylinder is located.

One of the display lamps Telescoping cylinder in foot section I, II, III, IV or V displays the position of the telescoping cylinder. The corresponding display lamp illuminates when the head of the telescoping cylinder is at the locking point in the foot section of the respective telescope section. Definition: When the statement “ The telescoping cylinder is in foot section II” appears in the following chapters, this means that “ the head” of the telescoping cylinder is in the foot section.
In our example “Initial position” is defined as the following: The telescoping cylinder in telescope section IV is locked, thus the head of the telescoping cylinder is there. The display lamp Telescoping cylinder in foot section IV would illuminate accordingly. Checking the position of the locking pins If you know in which telescope section the telescoping cylinder is located, check the positions of the locking pins as the last initial position.

Unlocking telescoping cylinder
In our example the green indicator lamp telescope section locked would illuminate and thus display that telescope section IV is locked to telescope section III (it was presupposed that all telescope sections are locked to one another). The green indicator lamp Telescoping cylinder locked would in addition illuminate (it was presupposed that the telescoping cylinder is locked to IV). Present state: – telescoping cylinder is locked in foot section IV – The next objective: – Unlock telescoping cylinder –
Before you can move the telescoping cylinder from one telescope section into another telescope section, you must unlock the telescoping cylinder. The locking pins on the telescoping cylinder retract when unlocking. Prerequisites for the unlocking of the telescoping cylinder:

If the locking process is not finished after about 10 seconds (warning lamp Telescoping cylinder unlocked is not on), you can not retract the locking pins because they are under load. With the Telescoping cylinder at locking point indicator lamps you can see if you need to retract or extend the telescoping cylinder to relieve the load. If only the bottom indicator lamp lights up, you must extend the telescoping cylinder. If both indicator lamps or only the top indicator lamp light up, you must retract the telescoping cylinder. Risk of damaging the boom system! If extending and retracting the telescoping cylinder several times does not cause unlocking, you must not move the telescoping cylinder any further against the stop.
If extending and retracting several times does not unlock the telescoping cylinder: – Lock the telescoping cylinder by pressing the Select locking/unlocking rocker switch up and moving the control lever. – Start the locking process again by pressing the Select locking/unlocking rocker switch down and moving the control lever.

Extending/ retracting telescoping cylinder and locking
In order to telescope a telescope section you must first move the telescoping cylinder into the foot section of the corresponding telescope section and lock it there. You can select the locking before the telescoping cylinder has reached the corresponding foot section. The crane control then locks the telescoping cylinder in the first foot section which is reached when extending/ retracting. That is why the exact time of the selection depends on whether the telescoping cylinder: – is to be moved and locked with an extended main boom – or is to be moved and locked with a fully retracted main boom. Before you telescope the telescoping cylinder with the selection, the following prerequisites must be fulfilled:
j i
– The telescope section in which the telescoping cylinder is located is locked, the green indicator lamp Telescope section locked illuminates. – The lock between the telescoping cylinder and telescope section has been released, the red indicator lamp Telescoping cylinder unlocked illuminates.
Moving and locking the telescoping cylinder with the main boom extended This case applies when you move the telescoping cylinder back after extending or retracting in order to telescope the next possible section. Before you extend or retract the telescoping cylinder, the prerequisites at the beginning of this chapter must be fulfilled.

• Check if the indicator lamp Telescoping gear switched on is on. • Move the telescoping cylinder; to do this, move the control lever in the corresponding direction. If the telescoping cylinder is moved without the telescope section, the crane control always switches automatically to fast speed. The following actions run parallel; you do not need to interrupt the extending/retracting of the telescoping cylinder. The telescope section begins to extend and the corresponding display lamp (e.g. Telescoping cylinder in foot section IV) flashes for the time being.

The retracting/extending of the telescoping cylinder with the main boom fully retracted has thus been finished.
The section “Moving and locking telescoping cylinder with completely retracted main boom” applies for our example. All telescope sections are fully retracted, thus the telescoping cylinder is situated in adjacent foot sections.

Telescoping telescope section to fixed length and lock
H
Read the sections concerning the fixed, intermediate, and telescoping lengths, the telescoping sequence and the functioning of the control lever at the beginning of this chapter and observe the notes for telescoping;
If you extend several telescope sections or want to work on a fixed length, you must extend the telescope section to a fixed length and lock it there. You can select the locking before the telescope section has reached the fixed length. The crane control then locks the telescope section at the first fixed length which is reached. Since every telescope section has three fixed lengths, the point in time of the selection depends on whether the telescope section: – is to be locked at the fixed length reached first – or is to be locked at the fixed length after the next. Before you telescope the telescope section with the selection, the following prerequisites must be fulfilled:
f
– The telescoping cylinder is situated in the foot section of the telescope section which is to be telescoped. The corresponding display lamp (e.g. Telescoping cylinder in foot section III) illuminates.
h
– The telescoping cylinder is locked to the telescope section which is to be telescoped; the green indicator lamp Telescoping cylinder locked illuminates.

In our example, the section “Locking the telescope section at the fixed length reached first” applies. Telescope section III should be extended to 50 %, so you can select locking as soon as the telescope section has been telescoped approx. 2 % from initial state. The values in this section are suited to the example. You can accept this section directly as an example. Present end state: – Telescope section III extended to 50 % – New objective: – Extend telescope section II – In order to reach the end position of the example from page 13-58, you would have to now extend telescope section II first. You would have to repeat the sections which are refered to in items 2 to 5 of the example on page 13-58. The steps are the same as with extending telescope section III. The initial and end positions would simply have to be changed for telescope section II and the status displays would change accordingly. This is the case for every other telescoping process. You can also telescope a telescope section without selecting the lock, as described in the next section. Before you telescope a telescope section to an intermediate length, the following prerequisites must be fulfilled:

Telescoping with fully automatic control
To telescope to fixed lengths you can also use the fully automatic control (teleautomatic control). To do this enter the desired telescope status in a submenu on the display crane control system and then steer the control lever out in the direction in which the telescoping should go. The locking and unlocking processes are carried out automatically by the crane control system.
H
Before you use the fully automatic telescoping, you must have read the entire telescoping gear section so that you can comprehend the locking and unlocking processes that the crane control carriers out. With the fully automatic control you can telescope the individual telescope sections only to the 0 %, 50 % and 100 % lengths. If you want to telescope one of the telescope sections to another length (e.g. 70 %), you can telescope with the fully automatic control at first to the next locking point (e.g. 50 %) and then telescope the last telescope section further with the semi-automatic control (e.g. to 70 %). You can only activate the submenu for entering the desired telescope status if – the Crane control display is in the Display telescope status and teleautomatism menu and – the telescoping gear is activated. You can start the sub-menu independent of the current telescope status.
• Switch on the menu Display telescope status on the display if necessary. • Switch the rocker switch Select locking/unlocking to the central position.

This telescope status now sets the crane control as the objective. The last line of the display is exactly as in the Display telescope status and teleautomatism menu.
The crane control now calculates the necessary telescoping sequence. In order to start the telescoping, you must move the control lever in the corresponding direction and hold it fast:
TRAINING INSTITUTE
• If you want to extend first, move the right control lever to the right. • If you want to retract first, move the right control lever to the left. The crane control telescopes fully automatically only until a change of direction is necessary; then the telescoping is interrupted and you must move the control lever in a different direction.
H
The other extension of the control lever for changing the direction is only necessary for extending a telescopic part. The telescoping cylinder moves automatically in both directions between the telescopic parts when changing, irrespective of the direction steered by the control lever. You can regulate the speed for telescoping just as for the semi-automatic control. The telescoping cylinder without telescope section always moves automatically in fast speed. You can leave the menu at any time by pressing the rocker switch Select locking/unlocking either upward or downward.
. ä
You can change from the menu Display telescope status and teleautomatism back to the submenu for entering the desired telescope status at any time. To do this press the membrane switch Display telescope status and teleautomatism once.

Lowering the main boom for maintenance
H
In order to lower the partly extended boom to an angle below that permitted in the operating area, you must enter an SLI rigging code. The rigging codes are found in the corresponding rigging curves of the Lifting capacity table. If the main boom is fully retracted and no load is raised, the SLI switches automatically to the rigging code when the working range is left.
• Put down the load. • If the main boom is not fully retracted, enter the appropriate SLI code for the current rigging mode of the truck crane according to the Lifting capacity table. • Turn the superstructure in the necessary direction;
G G
Risk of overturning with an outrigger span of 27.9 x 8.9 ft! With an outrigger span of 27.9 x 8.9 ft the main boom may be set down only in the 0° forwards or 180° to the rear positions. If you place the boom to the side with this outrigger span, the truck crane tips over even with the boom retracted.
Risk of overturning if SLI is overridden! If the SLI switches off the lowering of the boom, the truck crane is in a status in which the main boom can not be placed in a horizontal position (e.g. a raised load or extended too far). Do not override the SLI, put down the load if necessary and retract the main boom. • Lower the main boom to the horizontal position.
Telescoping the main boom in the horizontal position
• Enter the corresponding SLI rigging code for the current rigging mode of the truck crane according to the Lifting capacity table. The maximum permitted telescope status for the current rigging mode (counterweight, outrigger span, direction of rotation) is determined by the SLI rigging code. If this telescope status is exceeded, the SLI switches off the extending function.
• Put down the load.
H
• Extend the main boom only so far that the SLI switches off the extending function. If you continue to extend the main boom after an SLI shutdown, you can get into areas in which you can not retract or raise.

• Press the membrane switch Enter once to acknowledge; there are three possible reactions: – If no further error message is in the queue, the display switches to the menu which was selected before the error message occurred. – If further error messages are in queue, the next error message appears on the display. You can acknowledge all error messages one after the other. – If the error message was displayed because the crane control cannot detect any lengths and positions (proximity switch or length indicator is faulty or the line has been cut), the crane control switches to the submenu Emergency operation after the acknowledgement;
Calling up error messages again after acknowledging All acknowledged error messages are saved in the sub-menu Error memory. As long as the ignition remains switched on, you can call up the acknowledged error messages again:
> : < +
H
• To do this, switch to the menu Display states. • Call up the menu item for the power unit for which the error message appeared.
Switch to submenu Error memory. Here you can see the acknowledged error messages again. The error memory is deleted each time the ignition is switch off. As long as the cause of error is not eliminated, the error message appears after switching on the ignition and is again stored in the error memory after acknowledging. In this way you can also note the error messages later if you have switched off the ignition, e.g. to contact GROVE Product Support.
