Abstract
A system of controlling a lowering speed of a work lever of a forklift which includes, a hydraulic motor connected to the work lever through a hydraulic line to transmit a power to the work lever; an electronic solenoid valve for controlling the hydraulic motor connected to the work lever; a weight sensor 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; and a controller for controlling an RPM of the hydraulic motor and a current amount of the electronic solenoid valve based on the measured value transmitted from the weight sensor.
