The invention discloses a current-restriction controller for an electric chain hoist. The current-restriction controller for the electric chain hoist consists of a working power supply portion, a peak averting and delaying starting access circuit, a master control circuit, a restriction benchmark conversion circuit and an overload releasing circuit, wherein the working power supply portion is respectively connected with the restriction benchmark conversion circuit, the peak averting and delaying starting access circuit and the overload releasing circuit; the peak averting and delaying starting access circuit is respectively connected with the master control circuit and the overload releasing circuit; and the master control circuit is connected with the overload releasing circuit. Power supplying of a coil of the original relay of the electric chain hoist is retained. The current-restriction controller is simple in wiring and low in power consumption during work, serves as an overload protecting device, and can be widely used for electric chain hoists.
