Dearborn Overhead Crane features R&M Wire Rope Hoists.
R&M Spacemaster Electric Hoists
R&M Spacemaster SX Electric Hoist
QX
Modular Crane packages are pre-engineered, complete crane component
packages utilizing cutting edge technology including the innovative
Spacemaster® SX electric wire rope hoist. Variable frequency drives
are standard on trolley and bridge motions for smooth starts and
stops. Plug-in electrical cabling and bolted structural connections
simplify assembly.* The QX package includes virtually everything but
the bridge girder.
The Spacemaster® SX electric wire rope hoist represents a revolutionary new generation of exceptionally reliable electric 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 headroom 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 include 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 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" of 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.
The 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. Inverter control is available as an option.
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. Trolley bumpers are standard
