The hydraulic braker is used for the swing、hoisting and such mechanism. This product can work with the core in the wild for a long time and has features of compact structure、small volume、light weight、simple installation and convient maintanance.

二．Structure and Working Principles

The hydraulic brake is made of housing、piston、dynamic and static friction plates. It is under the state of normally-closed braking. When the pressure oil is drained into the input port of the hydraulic brake, and the pressure is between 2.5 to 3 Mpa, the hydraulic brake is open. The opening time of the hydraulic brake should be earlier than the time of going into operating the matched motion mechanism(Eg.:hydraulic motor), or else the motor part may be damaged because of overlarge torque. This hydraulic brake can work under the state of half-dry.

Braking Torque 300N·m

Braking Turning on Pressure 2.5-3Mpa
