Kito Crosby has announced the addition of Harrington brand hazardous location electric chain hoists to their three-phase electric chain hoist line.
These revolutionary hoists are designed for use in hazardous locations (HazLoc) where fire or explosion hazards may exist due to flammable gasses or combustible dust. These hoists are certified and listed by UL Solutions, a renowned Nationally Recognized Testing Laboratory (NRTL) for use in hazardous locations and have been rigorously tested, accordingly.
Hazardous locations are defined in NFPA 70, “National Electrical Code (NEC)”, the most widely used guidelines and regulations that govern safe installation and use of electrical wiring and equipment in the United States, using a class, division, and group system for identification of environments.
Examples of Class II (Dust) environments could include factories that produce starch, candy, medicine, fireworks, sugar, salt, flour and feed mills, grain elevators, and plants that manufacture, use or store magnesium or aluminum powders.
Each class is split into divisions that measure the likelihood of hazard. Division 1 refers to a hazardous location where flammable gases or vapors or combustible dust are likely to be present under normal operating conditions, meaning there is a high probability of an explosive atmosphere existing. Division 2 indicates a location where flammable or combustible materials are handled but are normally confined within closed systems, so an explosive atmosphere is only likely to occur under abnormal conditions like a container rupture or system failure.
RNER2 hoists are available in three different models for various hazardous location atmospheres as defined by the NEC:
- The RNER2 model is suitable for Class II Division 2 with protected dust groups F (Coal) and G (Grain).
- The RNER2B model is designed for Class I, II Division 1 with protected gas groups C (Ethylene) and D (Propane) and with protected dust groups F (Coal) and G (Grain).
- The RNER2D model meets the requirements for Class I Division 2 with protected gas groups of B (Hydrogen), C (Ethylene), D ( Propane).
Capacities range from 1 Ton to 5 Ton with a standard 10’ lift and are available in either a top hook configuration or with a trolley if additional mobility is required. Standard configurations of the RNER2 model, including certain options, are certified and listed to applicable UL standards and are marked UL. The RNER2B and RNER2D models are listed to applicable UL and CSA standards bearing the cULus mark.
Standard premium quality features include low-headroom upper and lower limit switches, a long-life slip clutch protecting the hoist from damage, super strength, nickel-plated load chain and the industry-proven “The Guardian” Smart Brake Technology, our failsafe maintenance-free brake with a 10-year warranty.
