Electric hoist is driven by the power a small light lifting equipment, appearance, light weight, small size, convenient and flexible. For more weight and the requirements of the scope of work or not is not high speed performance is required to work.
Electric hoist wire rope electric hoist and chain electric hoist, and has the fast and slow. Slow type often used for lifting liquid alloy casting or mold, sand box of shipment. Wire rope electric hoist lifting mechanism is done by motor driving cable drum lifting movement.
Electric hoist is installed in a certain span and the height of the beams in orbit, forming the electric monorail crane. Beams model and span varies according to the electric hoist lifting weight.
Electric hoist is made of electromagnetic brake, improve motor, light hook, reel and steel rope, gear mechanism. The electric monorail crane has track walking motor, wheel and level. With conical brake motor usually adopts three-phase with the conical rotor motor or the magnetic circuit of the motor, provide hoist lifting or horizontal movement of the driving force. With lower suspension cable hanging with lifting and walking button switch box, for the ground control. Put on one side of the drum motor, with elastic coupling in a drum at the other end of the reduction gear. Check motor another fan axis in the end, with conical brake. Power electric motor, the rotor shaft magnetic effect, to overcome the pressure of the spring, make its move to the left, fixed on the rotor shaft conical brake and motor end cover after the release, the rotor under the action of the spring, even the coaxial taper on the brake to the right, end cover after close contact with the electric machine, the friction torque motor stop.
