Spacemaster SX Electric Wire Rope Hoists

Supplier: R&M

The Spacemaster® SX Electric Wire Rope Hoists from R&M Materials Handling represents a revolutionary new generation of exceptionally reliable electric wire rope hoists, featuring advanced technology and cutting-edge performance.

An innovative design that includes a large drum diameter gives Spacemaster® SX hoists the lowest headrooms and best wheel loads in the industry while providing near true vertical lift with single reeved hoists, and both exceptional hook approaches and heights of lift.


  • New low maintenance, sealed brakes, a two-speed hoist motor, and trolley inverter control.
  • Standard hoist nameplate will carry a CSA c/us rating as well as a NEMA 3R rating for electrical enclosures.
  • Two-component epoxy paint is standard.
  • Designed to meet and exceed either ASME H3 or ASME H4 duty (FEM 1Am, 2m, or 3m) ratings.
  • Provides the ultimate in easy load handling, safe operation and lasting, trouble-free performance.

Standard electric wire rope hoist configurations include normal headroom, low headroom and double girder trolley designs. Hoists in short ton ratings (ASME) or metric ratings (FEM) meet a wide variety of application requirements:

  • 1/2 - 80 ton (500 - 80,000 kg) capacities.
  • Lifts starting at 13ft (4m) to 320ft (100m) and beyond
  • Lifting speed range 10/1.5 to 62/10 fpm (3/0.5 - 19/3 m/min)
  • 208, 230, 460, 575/3/60 or 380/3/50 power supply
  • Single-reeved or double-reeved.


  • Large-diameter hoist drum means easy positioning, closer approaches.
  • Larger drum diameter provides near true vertical lift with a single reeved hoist — only 1/8" drift per foot of lift.
  • Exceptionally smooth movement and fast load positioning.
  • Innovative design also means a shorter frame length, allowing closer end approaches.
  • Hoist and trolley motors designed for space savings and productivity.
  • Standard two-speed hoist motor (6:1 ratio), designed specifically for hoisting applications.
  • Hoist motor is class F insulated, 30 minute rated (60% effective duty), thermally protected and totally enclosed.
  • Trolley motor's standard inverter control offers two-speed multi-step or infinitely variable speed control for smooth acceleration and deceleration.
  • Minimal load swing, fast, efficient handling and accurate load placement.


  • Electromechanical load limit switch prevents the lifting of loads that are in excess of 110% of rated capacity.
  • 4-position hoist limit switch includes an innovative phase mismatch protection circuit.
  • Sealed brakes, hardened ground gears, thermal motor protection, exceptional rope life and ergonomic hook block design with sturdy safety latch.


  • Sealed brakes mean long-term value.
  • Sealed dust-proof brakes on the trolley.
  • Trolley design reduces wear on components.
  • Hoist motors require little adjustment for over a million cycles and will last the life of the hoist under normal use.
  • Trolley drive is totally enclosed, grease lubricated and is designed to be maintenance-free.
  • Trolley wheel bearings are permanently lubricated.
  • Automatic disc brake and inverter control help extend the life of the motor and other components.
  • Less maintenance, less downtime, lower repair costs – and reduced cost over the lifetime of your hoist equipment.


  • Innovative gearbox provides dependable operation and extends equipment life.
  • Innovative gear case design reduces stress on drum bearings.
  • Hardened and ground internal reduction gears driving an external drum gear located on the inner surface of the rope drum.
  • Gearbox's semi-fluid grease lubrication also helps to extend its working life.
  • Gear case is designed to run cooler and more efficiently than those equipped with a mechanical load brake.
  • Larger hoist drum minimizes rope wear and enhances cooling.
  • Drum/rope diameter ratio of approximately 40:1 minimizes rope flex.
  • Drum's large diameter also contributes to a reduction in frame size and weight.
  • Unique placement of the hoist motor inside the drum provides directed airflow through the drum for optimal motor cooling.
