Product Feature

The design of the double boom structure bring a significant improvement in stability and convenient for transport.


The main hydraulic system adopts the negative flow control, and adopts the main power control and limit power control together which can increase the system efficiency and make the most of the engine power. It adopt three-in-one colling system which is tightly packed and has a high-effeciency in cooling.


The imported Cummins turbo-supercharged engine (meeting EU-Ⅲ standard) is powerful, and has sufficient power reserve, which can be operated in plateau. Its noise and emission meet the national standards. The constant power and the best output enable the complete machine to function at its best.


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 rotary drive can switch from Nromal Mode, Rock Mode and Energy-Saving Mode, the user can select a corresponding mode of the rotary drive according to the specific working conditions, which can greatly improve the working efficiency and low the fuel consumption.


Optional configuration according to customers' requirement, E.g: Crowd winch, Outrigger cylinder, Sleeve-driven and so on.

It is equipped with a centralized lubrication system as standard configuration to provide more convenient maintenance and make the machine a good reliability .
