Evaluation in Japan Caterpillar 345B Series II Slow compound operation is a weak point of this machine. The boom will not rise when boom is raised, arm is moved in, and bucket is curled simultaneously. simultaneously.

Hitachi ZX450 Lack of response from work equipment is a weak point of this machine. When arm OUT operation is started just after arm IN operation, the work equipment response is very slow.

TREND OF REGULATIONS FOR CONSTRUCTION EQUIPMENT Emission Stricter emission regulations will be applied to construction equipment worldwide in order to preserve

the global environment. The time to enforce the new emission regulations will depend on the engine output range.

PROVEN HYDRAULIC SYSTEM The high output engine combined with Komatsu’s proven HydrauMind system provides high production and easy operation.

What is HydrauMind? The HydrauMind system symbolizes the new technology featured on the Avance series where the load sensing valves and pressure compensation valves handle all adjustments for individual work applications based on the proportional pressure and

lever stoke sensed. The load sensing valves are the “brains” of the Avance excavators allowing full automatic oil flow control without the need for computer control in all operations.

Benefits of HydrauMind system •

•

You can operate all work equipment easily and as desired. For example, when the ground condition changes in digging, the required oil amount automatically flows to the actuators. You do not have to worry about lever stroke or the computer program.

•

•

•

1. Work equipment speed is determined only by lever stroke. Whatever the position of the work equipment control lever, all the oil flow from the pump goes to the actuator. Even if the load on the actuator changes, actuator speed remains the same. t n e m p d k e r i e o u q p W e s

No speed change due to load

r e w o P

Max.

Under heavy/light load Lever stroke

Lever stroke FVPM2867

When moving the boom, arm and bucket at the same time, all equipment works, just like a human hand, at the optimum combination of speed and power without using any electronic device. The finest controllability you have ever experienced. Changing or adding valves and work equipment is easy.

2. Compound operations not affected by load. When two or more actuators are operated at the same time, the oil is divided and sent to each actuator corresponding to the lever stroke, regardless of the size of the load. There is no problem of excess oil flowing to the circuit at light load, and operations can be carried out simply in accordance with the operating feel. t e d k e c e u p B s

Righthand lever

d e m e r p A s

Lefthand lever Time FVPM2868

Effective work using HydrauMind system Fine control with lifting operations is easy. The work equipment speed corresponding to the control lever stroke is constant, so it is easy to start movement without being affected by the size of the load being lifted.

Reverse scraping operations are easy. The arm can be moved slowly under full power, ensuring easy operation.

PROVEN HYDRAULIC SYSTEM continued Work with additional attachments is easy Even when attachments such as breakers or crushers (which require a different amount of oil) are used, the flow of oil can be adjusted simply by adjusting the movement of the control pedal for the attachment. (= spool operating area) Breaker

It is to easy transport fresh concrete. Fine control of compound operations can be carried out easily.

Crusher

FVPM2875

FVPM2871

It is easy to scrape down. Even without operating the lever to the maximum position, maximum digging power can be obtained, making it possible to carry out slow control.

It is easier to fully load the bucket. During simultaneous operation, the work equipment moves slowly at maximum power, without being influenced by the other actuators, so it is easy to fully load the bucket.

Slowly

FVPM2876 FVPM2872

It is easy to carry out digging work along the faces of walls. Lateral power pushing is powerful allowing digging operation to be carried out efficiently.

It is easy to operate the crusher and work equipment simultaneously. The oil flow is divided according to the movement of the lever, regardless of whether the load is heavy or light.

FVPM2873 FVPM2877

The machine can carry out operations easily without any undue chassis vibration. During simultaneous operations, there is no change in the work equipment speed caused by change in load, thus, there is minimal chassis vibration.

It is easy to dig soft rock or dig up boulders. It is easy to control the boom RAISE, so the cutting edge does not deviate from the boulders.
