Electric chain hoist capable of achieving double-power-source switching

The utility model discloses an electric chain hoist capable of achieving double-power-source switching. The electric chain hoist comprises a double-power-source lifting motor which is a nine-wire system double-winding three-phase asynchronous motor. The serial numbers of wire-out ends of nine wires of the double-power-source lifting motor are arrayed in guiding-out wire ends of a double-power-source motor in sequence. The guiding-out wire ends of the double-power-source motor are connected with two-gear type universal change-over switch for 230 V-460 V power source switching. A rotary knob for 230 V-460 V power source switching is arranged on the surface of the universal change-over switch. Through the nine wires which go out through the nine-wire system double-winding three-phase asynchronous motor, free switching of double power sources is achieved via the two-gear type universal change-over switch, the electric chain hoist can be used on electric chain hoist products of various model numbers conveniently and can also be used on a crane or electrical equipment with similar functions, flexibility is high, the special requirements of foreign customers on products can be met, export prospect is good, practicability is high, design is novel, and a great innovation scheme is achieved.
