Spring-engaged, hydraulically disengaged brakes are for dynamic braking and static holding.
Features & benefits
Withstands temperatures to -30° F, unlike pneumatically actuated counterparts that withstand only 0° F
Fixed-point pivots for equal braking force to both rotor sides; various friction materials
Quick-release pins allow easy brake shoe removal from actuator arms for friction-pad replacement
Nested spring design minimizes spring-force losses
Ports with large Cv values ensure fast actuation, even when the hydraulic fluid is at lower temperature.
Disengagement pressures: 75 to 1,500 psi
