Forklift can travel without stepping on the accelerator.

The torque converter is used as a gearbox device instead of a gearbox clutch. Throttle, also known as "throttle" and "throttle". Refers to the control device that controls the power (thrust) of the engine. The reason why the small forklift truck with stepless speed change goes without refueling door is because the hydraulic torque converter is used as the transmission device instead of the transmission clutch. So in theory, as long as the gear is shifted and the brake pedal is not pressed, the engine will always have power output to the gearbox and wheels. Therefore, as long as the road conditions are smooth, the forklift still has the ability to walk at idle speed. Therefore, the forklift truck walks by itself without stepping on the accelerator, and uses the hydraulic torque converter instead of the transmission clutch as the eastward transmission device.
