Abstract: The present invention relates to a hoist control circuit equipped with an overload prevention circuit for a single-phase mini-chain hoist, and to a mini-chain hoist having the same. The hoist control circuit of the present invention comprises: an interlock push button unit including up- and down-manipulation buttons separately connected to a first wire to which external input power is applied; a power bridge diode connected to the first wire to rectify the input power; a driving bridge diode having a first input terminal connected to an electromagnetic contactor and a second input terminal connected to the electromagnetic contactor through a rotor of a motor, and receiving applied voltages in different directions generated by operation of a first or second switching unit of the electromagnetic contactor to apply AC voltage to a starter coil of the motor; and an overload prevention circuit for receiving the input power through the first wire, receiving a detection signal from a current transformer detecting current flowing through the first wire, having a relay connected between the up- or down-manipulation button and the first wire and activated when the detection signal exhibits overcurrent, and having a first b-contact switch serially connected to the up-manipulation button between both ends of the first wire and turned off by operation of the relay. According to the present invention, an accident and damage to cargo during work can be prevented.
