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.
