  • Crown tread wheels standard on push and motorized trolleys, for use on standard I-beams and wide flange beams.
  • Plug-in push button pendant with E-stop for quick replacement is standard
Reduced Maintenance: Quality Keeps Your Hoist on the Job Long Past the Pay-Off Point

The R&M LoadMate® electric chain hoists are designed to run cool and maximize the life of gears, brakes and motors. Longer component life means less maintenance, less downtime and lower repair costs.

  • Sealed brake keeps out lubricants.
  • The R&M LoadMate hoist brake and load limiter are both adjustable and adjust independently of each other.
  • Hoist gearboxes: LM1: AGMA10, LM05 & LM10: AGMA 11 and LM16/25: AGMA 12.
  • Traveling gearboxes: AGMA 10.
The Toughest Hoist Gearbox in the Business
  • Minimum AGMA 10 heat treated gearing
  • Grease lubricant on LM01-LM10 models. Gear oil for LM16-LM25
  • Quiet gear train – < 75 db
Two Part Chain Guiding System
  • One piece heavy duty pressure cast aluminum chain guide at entry point
  • One piece heavy duty ductile iron chain guide above load sprocket
  • Main entry point chain guide can be easily removed (only 1 bolt and 4 limit switch wires) WITHOUT disassembling hoist
  • Micro switches for hoist travel limit mounted in chain guide for easy maintenance
High Performance Electric Chain Hoist Motor
  • Heavy duty type 40% to 50%+ ED rating (exceeds 30 min rating) on three phase motors
  • IP55 protection
