MagnaShear Crane Brakes Feature Oil Shear Technology For Extended Life

No Adjustment – Ever! Reduces Maintenance Cost and Downtime
Electric Release Spring Set Brakes for Trolley, Carriage, or Hoist

MagnaShear Crane BrakesThe MagnaShear electric release spring set motor brakes are ideal for cranes.

The low maintenance and “no adjustment – ever” benefits attributed to Oil Shear Technology reduce the number of times someone crawls to the crane to do routine maintenance or replacement of the brakes.

Safety is a prime concern in crane design and operation, and using Force Control MagnaShear brakes is a step in the right direction.

Dry friction brakes that continually wear reducing torque require constant adjustment, and parts replacement. The MagnaShear oil shear brakes with oil shear technology maintain constant torque 5 to 10 times longer than dry friction brakes. No surprises when that extra heavy load is moved.

The totally enclosed housing protects the brake from contaminates including dust, dirt, moisture and chemical fumes. Applications such as chemical dip tanks can cause simple brakes to corrode, and fail. Marine and washdown duty options make the MagnaShear brake ideal for outdoor cranes marine applications.

Designed to operate on 120 VAC power a simple step down transformers is used for other voltages. This means the same brake can be used with VFD’s where typically control volt is run from the panel, 230/460 volt if connected to the motor leads, or any other voltage. Even direct DC can be used with custom design.
