The R&M Spacemaster® SX 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 wire rope 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. Unique features included new low maintenance, sealed brakes; a two-speed hoist motor; and trolley inverter control. A NEMA 4 type control enclosure is also standard. Spacemaster® SX wire rope hoists are designed to meet and exceed either ASME H3 or ASME H4 duty (FEM 1Am, 2m, or 3m) ratings and provide the ultimate in easy load handling, safe operation and lasting, trouble-free performance.

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

• 1/2 - 75 ton (500 - 75,000 kg) capacities
• Lifts starting at 13ft (4m) to 320ft (100m) and beyond
• Lift speeds 10/1.5 - 62/10 fpm (3/0.5 - 19/3 m/min)
• 208, 230, 460, 575/3/60 or 380/3/50 supply
• Single reeved or double reeved

Large-diameter hoist drum means easy positioning, closer approaches.
The larger rope drum diameter provides nearly true vertical lift with a single reeved hoist — only 1/8" drift per foot of lift. The result is exceptionally smooth movement and fast load positioning. This 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, offers high starting torque and ensures precise and reliable load handling.

This motor is class F insulated, 30 minute rated (60% effective duty), thermally protected and totally enclosed.
