Technical Field
[0001] The utility model relates to the technical field of hook arm boxes, in particular to a two-box loading and unloading platform for hook arm boxes. Background Art
[0002] At present, the hook-arm trucks on the market transport hook-arm boxes in a one-carriage-one-box operation mode. The long-distance transportation mode will result in high freight costs for the hook-arm truck to transport back and forth, frequent round trips, and high labor costs.
[0003] In addition, the method of transporting two hook arm boxes by semi-trailer requires the use of corner pieces for connection. The hook arm box structure needs to match both the semi-trailer and the hook arm truck, which makes it difficult for the hook arm truck and the semi-trailer to match and dock well. The function operation is complicated, and because the chassis of the hook arm truck is lower than the chassis of the semi-trailer is higher, the box cannot be placed directly on the semi-trailer. Therefore, the mode of transporting two hook arm boxes by semi-trailer is difficult to solve and popularize.
[0004] Finally, due to the interchangeable matching of the hook arm boxes between the semi-trailer and the hook arm truck, the semi-trailer, the hook arm truck and the hook arm box all need to be modified to varying degrees, which may bring safety hazards such as illegal modifications or the vehicle failing the annual inspection.
