MagnaShear motor brakes: Maintenancefree solution for onboard and port-side
cranes
Jun 27, 2014 04:10 PM
(FAIRFIELD, Ohio) — The MagnaShear marine duty motor brake from Force
Control Industries employs oil shear technology, providing longer service life even in
demanding applications like the frequent start/stop cycles seen on cranes, hoists,
winches, and other marine material handling equipment. High grade castings,
marine duty coatings, stainless steel fasteners and accessories make these brakes
an ideal solution for onshore and offshore crane applications. 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.

The oil shear technology also provides a smooth “cushioned” stop which reduces
shock to the drive system, further extending service life of downstream components.
The totally enclosed MagnaShear brakes are impervious to moisture, dirt and dust
that is common in concrete block plants as well as asphalt shingle manufacturing,
coal, bulk materials handling, forest products manufacturing, and more.

Unlike dry brakes, oil shear technology includes a layer of automatic transmission
fluid between the brake disc and the drive plate. As the fluid is compressed, the fluid
molecules shear — thus imparting torque to the other side. This torque transmission
causes the stationary surface to turn, bringing it up to the same relative speed as
the moving surface. Since most of the work is done by the fluid particles in shear,
wear is virtually eliminated. Elimination of wear also eliminates the need for
adjustments which are common for dry braking systems.

In addition to transmitting torque, a patented fluid recirculation system helps to
dissipate heat which is the major problem with traditional dry brakes.
Along with heat removal and torque transmission, the fluid serves to continually
lubricate all components of the oil shear brake, elongating their service life.
