Acco WRIGHT® Hazardous Location Wire Rope Hoists

Hazardous Location Hoist Customizable for Specific Class, Group and Division

Acco Wright® Speedway® and Work-Rated® wire rope hoists are designed for hazardous locations and can be ordered for specific Class, Group and Division applications. Spark resistant options are also available.

HEAVY-DUTY MOTORS

Hoist and trolley motors are manufactured and labeled for the specific location for which they are designed. Hoists are available for 208/230/460/575V 3-Phase 60Hz power supplies. Hoists can also be built for 380/415V 3-Phase 50Hz power supplies. Consult with the factory for power supply requirements not listed above.

Controls

Single speed and two speed controllers are available for all area classifications noted. Variable frequency drive (VFD) controls are available for most classifications.

BRAKES

A/C disc hoist brake and optional disc trolley brake are manufactured and labeled for the specific location for which they are designed.

Control Enclosure

A NEMA 4/7/9 cast aluminum control enclosure is provided for all Class 1, Division 1 or 2 and Class 2, Division 1 locations. A NEMA 12 dust-tight control enclosure is provided for all Class 2, Division 2 environments. All electrical conduit and fittings used meet or exceed the location requirements.

LIMIT SWITCHES

Upper gravity limit switch and overload cutoff device (overload is optional on Speedway® hoists) are intrinsically safe, eliminating the need for bulky limit switch housings. Optional upper/lower geared limit switches are also intrinsically safe.

PENDANTS

Control pendants are available in a NEMA 7/9 enclosure or in a NEMA 4X enclosure with intrinsically safe controls.

SPARK RESISTANT OPTIONS

Electrical classifications are just that. By specifying a Class, Group, & Division, you are simply requesting the required components for the electrical equipment provided on the hoist. Spark resistant options are strictly for the mechanical portion of the hoist, and may or may not be required for your application. Bronze & stainless steel trolley wheels, stainless steel wire rope, bronze & stainless steel load hooks with stainless steel latch, bronze coated hook with stainless steel latch are the most common mechanical options.
