Product Performance

◆The performance of the whole machine is well matched

The performance of the whole machine is reasonably matched, one machine is multi-purpose, and the construction is suitable for a wide range of applications.

◆Fully hydraulic heavy-duty crawler chassis

It adopts hydraulic crawler chassis with strong stability. The chassis has high structural strength, and adopts heavy-duty crawlers for easy transportation and quick and convenient shifting.

◆Adjustable speed hydraulic motor drive

The walking, hoisting, and slewing mechanisms are all driven by hydraulic motors, which are convenient for speed regulation and Compact structure, stable operation, strong impact resistance.

◆Three-point structure

The column luffing mechanism adopts a three-point structure, which makes the whole machine have strong stability during construction. The column is designed as a circular structure of high-strength material, with high strength and rigidity, which can effectively ensure accuracy. And it has the function of front and rear fine-tuning, which is convenient and quick for pile alignment; it is equipped with a vertical instrument to quickly adjust the verticality.

◆Combined counterweight

Combined counterweight is adopted, and the counterweight combination is selected according to the working conditions.

◆Pulling force limiter

Equipped with a pile-pushing force limiter, it can alarm in time when the predetermined pile-pushing force is reached, so as to avoid personal injuries and accidents caused by overload or misoperation.

◆Strong power

The engine is Cummins engine, which meets international emission standards, energy saving and environmental protection, strong power, sufficient power reserve to meet plateau construction, and noise to meet international standards.
