Jiaozuo Hongfa SDBH-I series of hydraulic failure protection disc brakes



SDBH_I series of hydraulic failure protection disc brakes

Overview: often closed design, hydraulic Brake meet JB / T10917-2008 "disc brake caliper" standard. Fully automatic with the device to ensure that the brake release state and the brake disc gap equal to avoid floating paste phenomenon. A center-high tunability can effectively compensate for mounting errors occur in the field. Equipped with AC and DC wide voltage gate and wear sensor switch, can be interlock protection and fault warning. Widely used in large and medium-sized cranes, port loading and unloading machinery lifting and boom tilting mechanism Low speed shaft emergency safety brake, mine hoist, hoist and high power inclined belt conveyor working brake and emergency safety brake, cable car and cable Cable crane drive mechanism of the safety brake, casting cranes and other special crane hoisting mechanism low speed shaft safety (emergency) brake.

Conditions of use:
Working oil pressure: 8-9.5MPa.
Ambient temperature: -5 ℃ - 40 ℃.
