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.
Unlike the Spacemaster EX Class I, Division 1 hoist, it does not require intrinsically safe circuitry for control commands and limit switches or armored motor cables.
Product Features
Like the Spacemaster SX, the EX features an innovative design that includes a large drum diameter, which enables both the lowest headroom and the best wheel load in the industry, while providing near-true vertical lift with single reeving. Employing a large diameter drum also makes it possible for exceptional hook approaches and lift heights. The Spacemaster EX is available within these ranges for Class I, Division 2 rated environments:
- 1 - 80 ton (1000 - 80,000 kg) capacities
- 460, 575/3/60 Hz or 380/3/50 Hz supply
- Two-speed hoist with 6:1 ratio, contactor control
- Two-speed trolley with 4:1 ratio, contactor control
- Low headroom, normal headroom and double girder trolleys
- Single reeved or double reeved
Safety features include:
- Spark-resistant wire rope as standard (EN 13463-5)
- ASME H3 or ASME H4 duty [FEM 1Am, 2m, or 3m] rating
- NEMA 4 and 7 protection rating for control enclosure
- CSA C/US approved
- ATEX 94/09/EC for manufacturers
- ATEX 99/92/EC for users
Spark-Resistant and Non-Sparking Options
Every Spacemaster EX hoist includes spark-resistant wire rope as standard. For Class I, Division 2 explosion-proof applications, R&M also offers non-sparking options that reduce the risk of sparks from metal-to-metal contact at the hook, wheels and trolley:
- Bronze coated hooks
- Brass wheels
- Brass drop lugs on the trolley
- Stainless steel wire rope
Each hazardous location hoist is configured to your application. Contact R&M to confirm which spark-resistant and non-sparking options fit your environment.
Hazardous Location Rating
This hoist is certified to meet Class I, Division 2, Groups B, C and D, T3 temperature class, carries an additional marking of Class I, Zone 2 IIB+H2, T3 and bears the CSA C/US mark. Class and Division rated equipment can be used in the appropriate Zone classified environment as permitted by the National Electrical Code (NEC 505.9 and NEC 505.20) and the Canadian Electrical Code (CEC C22.1).
Class I, Division 2 Applications
The Spacemaster EX Class I, Division 2 hoist is used where flammable gases or vapors are normally contained but may be present during a leak, equipment failure or abnormal operation. Common applications include, but are not limited to:
- Oil and gas: Gas processing units, compressor stations, pump maintenance areas and equipment service bays.
- Petrochemical processing: Refinery process units, chemical transfer areas and maintenance areas around processing equipment.
- Chemical processing: Chemical production areas, process equipment maintenance zones and areas near reactors or processing vessels.
- Paint and coatings manufacturing: Paint production and mixing areas, solvent-handling areas and manufacturing equipment maintenance zones.
- Industrial manufacturing: Classified production areas, process equipment maintenance bays and material-handling stations where flammable gases or vapors may be present.
Confirm your area's Class, Division and Group before specifying equipment. For areas classified Division 1, see the Spacemaster EX Class I, Division 1 hoist.
