Multiple Disc Brakes

Elite Multiple Disc Brakes are fully enclosed units that use coil springs and multiple friction discs to produce braking torque. These
brakes are applied by coil springs and released using hydraulic pressure. Maximum brake torque is achieved when hydraulic release pressure is zero. These brakes are self-applying in that any function which reduces hydraulic release pressure will begin to initiate brake clamping force.
These brakes are manufactured using high strength ductile iron
housings with nitrile case and shaft seals to keep outside contaminants from entering the brake.
Spline shafts are constructed of heat-treated 8620 steel and available in a number of different configurations. Available
in SAE A, B, C or D mounts with torque ranges from 113 to
11000Nm and release pressures from 6.9 to 34.5 bar
Typical applications
include a parking brake function or braking of a motor on manlifts,
scissor lifts, winches, swing drives, and other low speed vehicles and equipment.
