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. Unique features include new low maintenance, sealed brakes, a two-speed hoist motor, and trolley inverter control. The standard hoist name- plate will carry a CSA c/us rating as well as a NEMA 3R rating for electrical enclosures. Two-
component epoxy paint is standard. Spacemaster SX® hoists are designed to meet and exceed either ASME H3 or ASME H4 duty (FEM 1Am, 2m,
or 3m) ratings
Standard 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:
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. The hoist 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- speed multi-step or infinitely variable speed control for smooth acceleration and deceleration, minimal load
swing, fast, efficient handling and accurate load placement.
Standard safety features that competitors don’t offer— or offer at extra cost.
An electromechanical load limit switch prevents the lifting of loads that are in excess of 110% of rated capacity. The 4-position hoist limit switch includes an
innovative phase mismatch
protection circuit that prevents the block from running up and damaging the hoist in the event of
Sealed brakes, hardened ground gears, thermal motor protection, exceptional rope life and ergonomic hook block design with sturdy safety latch contribute to the hoist’s safe operation and increased reliability.

EASE OF OPERATION
Large-diameter hoist drum means easy positioning, closer approaches.
The larger drum diameter provides near 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.
