Abstract: The present invention relates to a system for regenerating the regenerative power of a construction work lift. Provided is the system for regenerating the regenerative power of a construction work lift which is able to improve energy efficiency by allowing the regenerated regenerative power that is generated from a driving motor which vertically drives a lift car to be transferred and be used as a construction field electrical power system or general electrical power system, to be further stably operated by continuously performing normal operation of a lift car under an ignorable abnormal condition, such as a momentary contact failure of one line of an electrical power cable, and to be further stably operated by preventing the risk of carry material damage and the risk of passenger injury in the lift car by receiving a common use power which is converted and output from a regenerative power conversion part and gradually stopping a driving motor so that the lift car is gradually stopped without suddenly stopping even though a power cable is disconnected and power not supplied.

Abstract: PURPOSE: A regenerated brake power restoring system of a lift for construction work is provided to stably supply power during the generation of an abnormal state and to increase the generation of regenerated brake power by operating a main operating motor for a lifting movement and additionally operating an extra sub operating motor during a descending movement. CONSTITUTION: A regenerated brake power restoring system includes a main operating motor (100), a sub operating motor (100a), an inverter unit (200), a regenerated brake power converting unit (300), a line monitoring unit (400), a sub contactor, and an inverter control unit. When a lift car (C) is lifted up, only the main operating motor is operated by the inverter unit. When the lift car is lifted down, both the main operating motor and the sub operating motor are operated.
