YDR100B is a two-speed hydraulic rotary head featuring an integrated reverse circulation structure for efficient cuttings and debris discharge.

Multi-stage speed and torque enabled by series-parallel switching of motors.

It can be matched with a pile driving power head to achieve torque amplification or rotation speed change.

Can be customized according to actual requirements.

Powerful Torque, Built for Large-Scale Foundations

Use variable piston motor, it can realize stepless speed regulation.
