New MagnaShearT hazardous duty brakes from Force Control Industries, which employ oil shear technology to provide longer service life with virtually no maintenance or adjustment, now meet Class I and Class II Div 2 specifications (Div 1 in process with approval forthcoming). With spring set torque ratings from 3 to 900 foot-pounds available, MagnaShearT motor brakes can be sized to the correct torque independent of the motor frame size or horsepower. They also feature "quick mount" features for quick and easy mounting to drive motors in NEMA frame sizes 56 to 405.
These proven motor brakes are totally enclosed from outside contaminants, with seal integrity for harsh and washdown environments. A modular design /assembly allows for ease of servicing and maintenance. MagnaShearT motor brakes are suitable for applications where the motor is reversed each cycle such as cranes, winches, and hoists as well as ship and railcar loader/unloader conveyors, tippers, sweep samplers and more.
Proven oil shear technology transmits torque between lubricated surfaces - thereby eliminating wear on friction surfaces, providing longer service life with no maintenance or adjustment. A patented fluid recirculation system dissipates heat - eliminating heat build-up which is the most common problem in dry braking systems.
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 MagnaShearT brakes are impervious to moisture, dirt and dust that is common in coal prep plants as well as the bulk handling of coal, aggregates, and more.
