Hydraulic disc brake
* Compared with conventional band brake, the hydraulic disc brake has a large braking-torque capacity and a stable braking performance with a small inertia, and it can be operated precisely and flexibly with convenience for debugging and maintenance.
* This hydraulic disc brake can be used for working braking, emergency braking, over-reel protection and shut off braking .
* There are motor-driven pumps and accumulators, manual pumps, heaters and coolers to be equipped on the hydraulic station with the purpose of a dependable hydraulic-force supply to the executed units.
* An integral layout can be realized by adoption of a valve-type connections on the power control system.
* Safety and inspection measures are strengthened under the guidance of the design concept of ¡°Humanism Above All¡± to meet the requirements of HSE.
