R&M Spacemaster® SX represents a
revolutionary new generation of exceptionally reliable electric wire
rope hoists, featuring advanced technology and cutting-edge
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
- 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
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
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.
The trolley motor's standard inverter control offers two-step or
infinitely variable speed control for smooth acceleration and
deceleration; minimal load swing; fast, efficient handling; and
accurate load placement.
