ptcc Vibrodriver pt hydraulic vibratory hammer, hammer, which vibrates The PTC Vibrodriver is an efficient hydraulic the profile, sheet pile or casing to be driven or extracted extracted through vertical vibrations. These vibrations transmitted via the profile cause the adjacent ground to shift, which results in a noticeable decrease in resistance between soil and pile. Consequently,, this enables the pile to be driven into the ground by its own and Consequently the vibrator’s weight. weight. This equipment also can extract the profile with the same principle, via the pulling force of the carrier (crane) in use use without any modifimodification. Vibrations generated by the Vibrodriver are transmitted to the element being driven via a connection (clamping (clamping head). Various hydraulic power power packs supply the required energy to the Vibrodriver.

The element to be driven or extracted is clamped under the gearbox via a hydraulic clamp. A yoke is located above the gearbox and prevents the transmission of vibrations through elastomer blocks. The heavy yoke causes an additional downward force with its own weight and can be increased by adding additional weights.

Clamping heads The function of the clamping heads, which are mounted under the vibrodrivers, vibrodrivers, is to firmly clamp the pile or casing to be driven or extracted. The clamping head is fed with high pressure oil by a hydraulic pump located in in the power pack.

Intermediate plate and Multiplex

The clamping heads must be adapted to the size of the vibrodriver, vibrodriver, as well as to the shape of sheet sheet pile, profil profilee or casing. Cons Consequen equently tly,, there are numerous numerous models and, only 6 basic types are shown shown below. below. On many cases cases it is necessary to check the selection of a clamping head to suit a particular application.

The 6 basic types:  

The Agriplex has a single ram and allows a single sheet pile or a H beam to be clamped. The Duplex clamping head for casings and caissons consists of two clamps which can be slid onto two T-bars. T-bars. The position of the clamps is determined by the casing diameter. diameter. A straight beam allows the clamping of casings with larger diameter.  The Multiplex has two hydraulic clamps which can be slid onto two T-bars, T-bars, like Duplex. They are mounted on an intermediate plate. This is especially useful for double double sheet pile applications (U or Z sheet piles).  The Quadriplex clamping head is foreseen to clamp particularly large casing casingss (Ø 2 m or above). It consist consistss of four hydraulic hydra ulic clamps clamps which slide on T-bars. T-bars. The T-bars T-bars are mounted on a special X-form beam (spreader beam), directly under the vibrator.  The Multigrip clamping head is for extracting (or driving) concrete or wooden piles which can be round or square (from 350 35 0 mm x 35 350 0 mm to to 450 450 mm x 45 450 0 mm mm). ).  The Tetagrip: PTC has designed designed a new clamping clamping head combined with intermediate plate, plate, to optimally drive drive profiles for combined walls (king (king piles + double Z piles).

Turning Plate, intermediate Plate and straight beam: Quadriplex

Agriplex

The Turning plate allows to mount mount clamping head at 90° to work nearer buildings.  The intermediate plate with simple structure insures an easy handling of different types of double U or Z sheet piles.  The straight beam is used mostly with Duplex clamp to drive larger casings.

H & HD Standard Frequency Vibrodrivers Hydraulic vibrators are the most widely used equipment for driving and extracting sheet piles, casing and profiles with excellent performance and precision. The HD or “HEAVY “HEAVY DUTY” type was developed for driving heavy heavy profiles and casing with proper weights up to 90 tons. Their large eccentric moments enable them them to generate the dynamic force with high amplitudes. Due to its design, design, the maximum pressure of the individual eccentric pairs is limited to 15 t which ensures a long working life for the bearings.

HFV & mHFV High frequency Vibrodrivers Vibrodrivers with variable amplitude

The patented high frequency vibrator with hydraulic control variable eccentricity (HFV) was introduced in 1992 and is a key development development for PTC. The HFV system distinguishes itself with its ability to start up and stop down without generating any vibrations. With amplitude amplitude contr control, ol, the vibration vibrationss transmitte transmittedd to the environ environment ment are are reduced to a minimum. Moreover Moreover,, the damaging vibrations transmitted to the crane booms are eliminated, eliminated, which allows contractors contractors to work with telescopic booms on mobile cranes. These models fall well within the new international norms for limiting noise and vibrations emissions, thus enable sensitive jobs to be operated in historic centres, city centres centres or close close to buildings buildings housing housing delicate equipme equipment nt etc. All the advantages of the high frequency vibrators remain valid. The exclusive advantages of variable amplitude vibrators: resonance-free start up and stop down; reduction of the noise level;  reduction of the vibrations transmitted towards the ground;  adapting the amplitude to the ground;  use and pre-setting in “delicate driving” driving” mode;  mHFV can be mounted on most excavators.  

The HFV working principle: Variation of eccentrics’ relative positions

The rotating eccentrics are kept in opposite positions, in all cases, at the start of vibration. The resulting moment moment is nil. This is no amplitude of vibration. vibration. For instance, instance, when half of rotating rotating eccentrics eccentrics have rotated rotated 60°, 60°, the resulting resulting moment moment and and amplitude amplit ude of vibration vibration are, are, then half of of their maximum values.

HF High Frequency Vibrodrivers High frequency vibration of PTC vibrators primarily reduces the friction between the soil and the pile because this sort of machines vibrates at frequencies higher than 30 Hz. Thus, high-freq high-frequency uency vibrators have been employed employed to avoid avoid resonance resonance which may damage neighbouring neighbouring structures. structures. The vibration also allows allows easy extraction of the pile by pulling on the excavator arm.
