About Bridge Drives

R&M's GEK and GES bridge drives achieve smooth acceleration and braking by utilizing a variable frequency drive as standard. Brake life is optimized as the inverter controls the speed of the motor to a stop before the brake sets. Fully enclosed gear units are specially designed in-house for crane applications to ensure many years of trouble-free operation.

GEK & GES Bridge Drives

  • Modular design includes gearbox, motor and brake for ease of maintenance
  • Totally enclosed, Class F, 30-minute inverter duty or two-speed motors
  • Motor brakes with asbestos-free friction material
  • Brakes are normally closed -if power fails, brakes will stop further travel
  • Antifriction bearings supporting all internal bearings in gear box, extending bearing life
  • Output shaft utilizes external spline connections for increase durability
