Brakes and release pumps
Our standalone spring-applied hydraulic release brakes provide 225 Nm to 1,500 Nm [2,000 lb-in to 13,300 lb-in] of reliable load-holding torque for critical machine functions, and our hydraulic release pumps are hand pumps used to release various types of spring-applied, hydraulically released brakes.
