WRIGHT® Hazardous Environment Hoists

Product Overview

Acco Material Handling Solutions specializes in producing a wide variety of wire rope hoists for use in hazardous environments. The New Century Series® Speedway® and Work-Rated® models can be ordered for specific Class, Group and Division applications. All Acco Wright® crane components are available for hazardous environment applications. In addition to the options listed for the hoists, spark resistant rail sweeps and intrinsically safe relays for pendants are available.

Hoists can be ordered for the following environments:


  • Groups C & D, Division 1
  • Groups B, C, & D, Division 2


  • Groups E, F, & G, Divisions 1 & 2

Definition of CLASS, GROUP, and DIVISION:

CLASS 1 – Locations where flammable gases or vapors are or may be present in the air in quantities sufficient to produce explosive or ignitable mixtures
CLASS 2 – Locations where flammable dusts are or may be present in the air in quantities sufficient to produce explosive or ignitable mixtures

GROUP B – Hydrogen, etc.
GROUP C – Ethyl-ether, ethylene, etc.
GROUP D – Gasoline, hexane, naphtha, propane, alcohol, etc.
GROUP E – Metallic dust
GROUP F – Carbon black, coal, coke, etc.
GROUP G – Flour starch grain, etc.

DIVISION 1 – Where combustible gases, vapors, or dusts are always present under normal operating conditions
DIVISION 2 – Where combustible gases, vapors, or dusts may be present under abnormal operating conditions



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.
