Background

The OPS warning function of the whole forklift is realized by arranging the enabling pedal switch on the common forward-moving forklift, and the electric counter-weight forklift is realized by the seat switch. The principle is that whether a driver is in a correct driving position or not is detected, and the safety protection function is realized. When a driver steps on the enabling pedal switch, the inductive switch is switched on, and then the forklift can perform lifting, walking and other functions; after the driver releases the enabling pedal switch, the lifting and walking functions are disabled, and meanwhile an OPS warning lamp on the instrument is turned on. Therefore, for a forward fork lift truck, when the fork lift truck works, the enabling pedal needs to be pressed down all the time, and the pedal switch which requires foot to be pressed down needs to be designed to save labor and sense a stroke.

The existing enabling safety switches have the following two forms: 1. the induction switch is integrated in a sealed box in a packaging mode, the stroke of the pedal cannot be adjusted, and the pedal needs to be integrally replaced during maintenance; 2. the lever mechanism type is adopted, the required installation space is large, and the stroke (idle stroke) of the front end of the pedal is large; the two forms have the defects that the foot manipulation force is heavier and the foot feel is poor, so that a labor-saving pedal mechanism for improving the man-machine performance is urgently needed.
