Performance Characteristics
It adopts dedicated hydraulic retractable crawler chassis and heavy slewing bearing and has high stability;
It adopts the luffing mechanism of large triangle form to ensure the stability of construction of big holes and deep piles in hard formation;
It adopts the front-located single-rope main winch structure to greatly prolong the service life of steel wire rope and lower the use cost;
The main and auxiliary winches both adopt single-row rope technology. The service life of wire rope is 2-4 times longer than that of multi-layer rope and the cost is lower.
Cummins electric control turbo-supercharged engine is used. It complies with Euro IIl emission standard In addition, it has strong power, which is sufficient to satisfy the construction on the plateau. Its noise is up to the national standard;
Using full electronic control technogy of CAN bus.Improves the reliability of the whole vehicle and simplify hydraulic line.Fully reflects the people,machine.electricity and liquid integration;
Normal mode and entering-rock mode of unit head are available for operation in soil and rock to improve the construction efficiency;
Winch-pressurized and sleeve-driven functions are available for selection to satisfy various needs of the users; It is equipped with a centralized lubrication system as standard configuration: maintenance is eas.
