explosion proof hoist
The Spacemaster® EX Class I, Division 2 Hoists are industry-leading, explosion-proof hoists for maximum safety in potentially combustible environments.

Why Choose a Hazardous Location Hoist? 

The Spacemaster®  EX electric wire rope hoist is the hazardous location version of the industry-leading Spacemaster SX hoist. An innovative design that includes a large drum diameter gives the Spacemaster EX hoists the lowest headrooms and best wheel loads in the industry, while providing near true vertical lift with single reeving, as well as exceptional hook approaches and heights of lift
