The invention provides a speed regulation device and method of a forklift lifting system, and belongs to the field of forklift equipment. The speed regulation device of the forklift lifting system comprises a lifting device and a controller; the lifting device comprises an oil pump, a motor, a valve and a lifting control rod used for controlling the valve, the lifting device is provided with a sensor used for detecting the open degree of the valve, the sensor is in electric connection with the controller, the controller is in electric connection with the motor and is used for controlling the rotation speed of the motor, and the motor is used for driving the oil pump to work. According to the speed regulation device and method of the forklift lifting system, the sensor detects the open degree of the valve of the lifting system and transmits a signal to the controller for processing, the controller controls the motor and adjusts the rotation speed according to the signal, therefore, the technical problem that when a forklift runs at medium and low speed, the motor still runs at high speed can be avoided, and the motor energy consumption can be reduced.
