The MagnaShear and PosiStop motor brakes from Force Control Industries (Fairfield, OH) employ oil shear technology, providing longer service life even in demanding applications like the frequent start/stop cycles seen on shipboard or port-side cranes, hoists, winches and other marine material handling equipment. Specifically:
- Proven oil shear technology transmits torque between lubricated surfaces – thereby eliminating wear on friction surfaces.
- A patented fluid recirculation system dissipates heat – eliminating heat build-up which is the most common problem in dry braking systems.
- Elimination of the wear significantly increases service life and virtually eliminates adjustment which also elongates maintenance intervals.
- They are ideal for applications where the motor is reversed each cycle such as cranes, winches, and hoists as well as loader/unloader conveyors, rail car spotters and dumpers, ship and rail car loading conveyors, trippers and pallet return conveyors.
