[0002] A forklift truck is a logistics handling device for handling goods. Compared with ordinary forklifts, a forklift truck has the characteristics of a small body and light self-weight, and can operate in narrow spaces or narrow aisles. At present, pallet forklift trucks on the market are usually divided into two types: walk-behind forklift trucks and step-on forklift trucks. When a walk-behind forklift truck is used at a handling station, the fork carried by it is inserted into the pallet hole, and a hydraulic system is driven by manpower to realize the lifting and lowering of the pallet goods, and the handling operation is completed by pulling by manpower. For example, the patent application with the publication number CN221397197U discloses a walk-behind single-fork manual forklift truck, which realizes the rapid and stable operation of small-volume objects through auxiliary wheels on both sides of the driving wheels and a single fork; the step-on forklift truck is driven in an electric manner to move forward, and an electric control lifting mechanism is used to realize the lifting and lowering of the pallet goods, and the user stands on the step-on forklift truck to drive. For example, the publication number CN118306929A discloses a standing electric forklift truck and a control method thereof, which includes a vehicle body, a standing platform located at the bottom of the rear side of the vehicle body, an operation handle located at the top of the vehicle body, and a folding guardrail located above the standing platform, and also includes a guardrail lock.
