Claims

[Scope of utility model registration request]

A loading platform, which is equipped with running wheels and is capable of independently loading and transporting cargo, is removably attached to a lifting device provided at the rear of the vehicle body, so that the lifting device can move up and down while maintaining a horizontal state. In the loading platform elevating device, the loading platform is mainly composed of an underframe and a pair of running wheels removably inserted into each pair of front and rear of the underframe, and the running wheels are composed of a wheel portion, a bracket, and a shaft. The underframe is provided with a boss into which the shaft is inserted, and this boss is provided with a circumferential groove having a circumferential portion and a straight portion reaching the inner diameter of the boss. A spring ring having a part is fitted so that the straight part of the spring ring corresponds to the straight part of the boss, a notch groove is provided in the shaft at a position corresponding to the straight part of the spring ring, and when the shaft is inserted into the boss. The straight part of the spring ring engages with the notched groove of the shaft, and the running wheel is attached to the underframe. When the shaft is rotated and the engagement between the straight part of the spring ring and the notched groove of the shaft is released, the running wheel is fitted into the underframe. A loading/unloading platform lifting/lowering device characterized by being able to be moved freely.
