Hydraulic disc brake 
Technical features:
1. 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.
2. This hydraulic disc brake can be used for working braking, emergency braking, over-reel protection and shut off braking.
3. 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.
4. An integral layout can be realized by adoption of a valve-type connection on the power control system.
5. Safety and inspection measures are strengthened under the guidance of the design concept of “Humanism Above All” to meet the requirements of HSE.
