— Piston Pump:

Open System:Small-tonnage HP5V medium-pressure pump can be used to improve the work efficiency through the matching of the main engine. At the same time, the spherical flow distribution technology is used to adapt to the high-speed impact conditions; Medium and large tonnage can choose V90N.DT/DP and V30G high-pressure pumps, and its heavy-duty design can well ensure the crane’s requirements for safe and be reliable hoisting applications.
Medium and large tonnage can choose V90N.DT/DP and V30G high-pressure pumps, and its heavy-duty design can well ensure the crane’s requirements for safe and be reliable hoisting applications.
Closed System:HP4VG series pump adopts electric proportional displacement control, with good proportional linearity, small hysteresis loop, high repeat control accuracy, good minimum stable output and dynamic stability, giving full play to pump control system performance.

— Piston Motor:

The motor to achieve better performance at low speeds: optimized rotation balance design, high-speed performance and smooth start characteristics.

— Hydraulic Cylinder:

It can be customized according to customer requirements to meet the application requirements of ordinary and special working conditions.
