Redundant design is used to provide reliable and reliable braking torque for drilling rigs.
The control system uses valve block embedded structure connection to reduce the external pipeline.
It can realize the functions of working brake, parking brake, overwinding protection, emergency brake and so on, and has the functions of power-off, air stopping and automatic stopping of liquid breaking.
The hydraulic station is equipped with a double electric pump and multi accumulator structure, and equipped with a manual pump, heating and cooling device, which provides reliable hydraulic power for the actuator.
