The present disclosure relates to a system of controlling a lowering speed of a work lever of a forklift which may realize a constant amount of change in the lowering speed of the work lever with respect to a valve opening area, irrespective of a weight of a load placed on the work lever, although a flow regulator is not provided.The system for controlling the lowering speed of a work lever of a forklift includes,a hydraulic motor (130) connected to the work lever through a hydraulic line to transmit a power to the work lever; an electronic solenoid valve (150) for controlling the hydraulic motor connected to the work lever; a weight sensor (140) provided at one side of the work lever, the weight sensor measuring a weight of a load placed on the work lever and transmitting the measured value to a controller (120); and said controller (120) arranged for controlling an RPM of the hydraulic motor (130) and a current amount of the electronic solenoid valve based on the measured value transmitted from the weight sensor (140).
