These hoists are designed in accordance with our interpretation of specifications of the Underwriters Laboratories, Inc. and Factory Mutual but have not been tested by them, nor do they carry their label. Components such as Motor Brake and Controls each carry the Underwriters or Factory Mutual Label.  Explosion Proof Electric Hoists are furnished with Explosion Proof Motor, Motor Brake, Control Enclosure, Limit Switch and Push Button Station to meet specifications for Class 1, and Group D Hazardous Locations.

SATURN ENGINEERING Electric Wire Rope Hoists can be furnished to numerous other specifications such as: Class 1, Groups C & D, Division 1 as well as Class 2, Groups E,F & G - whether it be Division 1 or 2. The only groups that we cannot furnish are A & B - where there are no motors available. In these applications and in others where an Air Hoist is desirable, see Section on Air Hoists.

The electrical components of hoists used in hazardous locations must meet the requirements of the National Electrical Code (NEC).  Control equipment must conform to standards established by the National Electrical Manufacturers Association (NEMA).  Motors are certified directly by the Underwriters Laboratories (UL) inspectors.  All such codes and authorities apply only to electrical equipment.   There is no national code covering explosion proofing (spark proofing) of mechanical components.  The responsibility for determining the existence and severity of the hazard in a specific area rests with the authority responsible for enforcing the code. Careful analysis of all conditions is necessary in order to establish the applicable Class, Group and Division.
