を特徴とするチルト速度制御装置。 A lift height sensor detects the lift height of the forklift, a control lever is used by the operator to issue commands for tilt operation, and signals are received from the lift height sensor and control lever, and when the lift is lifted high, A controller that outputs a low-speed tilt signal and sends a high-speed tilt signal when the lift is at low elevation, and a controller that receives a tilt speed signal from the controller and sends oil to the tilt cylinder when a low-speed tilt signal is received. A tilt speed control device comprising: an electromagnetic control valve having a flow control function that throttles the flow rate of the oil and increases the flow rate of oil sent to the tilt cylinder when a high speed tilt signal is received.
