HYDRAULIC TOP DRIVE

The hollow axle motor directly drives the main shaft, reducing the transmission energy loss and with the higher mechanical efficiency, less fault point and the higher reliability.

Non gear lubricating oil and cooling filtration system reduce the sealing mechanism for simple structure and easy maintenance.

Under the same power, hydraulic top drive can get a wider torque range compared to the electric top drive.

Top drive has high integration, constant power control, high overload capacity, high efficiency, high reliability and low maintenance cost.

Stepless speed regulation within rated speed range.

HPU can be driven by diesel engine or motor according to customer requirement.

Equip with disc brake, which is more reliable to release reverse torque.

Working environment temperature is -40℃~+55℃.
