Electric hoist is a special lifting device, installed on the crane, on the explosion-proof electric hoist gantry crane, electric hoist with a small size, light weight, simple hoist, easy to use features for industrial and mining enterprises, storage terminals and other places . Composition structure weight is generally from 0.1 to 80 tons, lifting height 3 to 30 meters. By the motor, transmission and rolls or sprockets, divided into wire rope electric hoist and electric chain hoist two. Wherein the chain hoist into two kinds of imported and domestic; wire rope hoist sub-single-speed lift, two-speed lift; mini electric hoist, hoist, hoist multi-functional. Reducer, lifting motor, run the motor off firearms, cable slide wire, drum equipment, hook device, coupling, flexible cable and other set current into power and braking force in one. Winch (also known as winches) is powered by a human or mechanical reel, reel winding electric winch electric winch pulling rope to complete the work of the unit. Can vertical lifting, horizontal or inclined entrainment weight. Manual winch hoist winch is divided into two kinds of electric. With electric hoist the main. Electric hoist by the electric motor, couplings, brakes, gearbox and electric hoist drum composition of imports, are commonly mounted on the rack. For lifting height and handling large work frequent, electric hoist bridge crane, speed performance, make empty hook rapid decline. In place of or sensitive materials, use a smaller speed. Common tonnage hoist: 0.5T, 1T, 1.5T, 2T, 3T, 5T, 6T, 8T, 10T, 15T, 20T, 25T, 30T. From the perspective of compliance with national standards: GB hoist winch can be divided into non-standard hoist.
