D.C. Disk Brake

 

Hoist Reducer

Three step helical gearing operation in oil bath with combination of deep grooved ball, special roller and cylindrical roller bearings. Machined steel gearing, carburized and ground tolerance.

 

Geared Coupling

The hoist gearbox is connected to the drum by a flexible two-stage geared coupling. The coupling type allows dynamic bending and movement of the drum, without the common fatigue failures.

 

Rope Drum

  • Rope overwrap protection
  • Right hand and left hand grooving for true vertical lift
  • Exceptional rope diameter to drum diameter ratio
  • Rugged coupling to connect drum to gear reducer
  • Drum flanges on both ends of rope drum extend past the wire ropes
  • Idler drum end: supported on self-aligning spherical bearing

New HoistWatch offered by R&M 

The HoistWatch is a condition monitoring unit that records key operational functions of the Spacemaster® SX wire rope hoist. 

The HoistWatch is a standard feature for Spacemaster® SX2, SX3, SX4 and SX5 single hoist with a P5 motor or smaller.

Key Condition Monitoring Parameters:

  • Number of starts (hoisting and lowering)
  • Running time (hoisting and lowering)
  • Hoist brake wear supervision (number of  braking operations)
    - Warning given when preprogrammed # of operations is exceeded (adjustable)
  • Control counter (number of directional contactor operations)
     -Warning given when preprogrammed # of operation is exceeded (adjustable)
  • Power on time (# of hours HoistWatch has been energized)
  • Number of overloads lifted

For more information on the HoistWatch, please refer to the June 2016 Spacemaster® SX Wire Rope Hoist Technical Guide.

 

HoistMonitor®

  • Overload supervision
  • Sudden load increase supervision
  • SWP (safe working period) hour counter
  • Motor function monitoring
  • Supply voltage phase supervision
