Preferably, the size of the main body part and the size of the turnover part are matched with the shape of the body of the overhead working truck provided with the main body part and the turnover part.

Preferably, the turnover part is rotatably connected to the main body part through a bolt and nut assembly. A connecting gap is reserved between the bolt and nut components, so that the overturning part can rotate freely.

Preferably, in the present invention, the cushion pad is made of rubber. The material and shape of the cushion pad can be changed as required.

As preferred, in the utility model discloses in spacing piece of hitting is the nylon material. The material and the shape of the limiting collision block can be changed as required.

Preferably, the main body of the utility model is further provided with a main body pedal.

Preferably, the turnover part of the utility model is further provided with a turnover pedal.

In the utility model, all the parts in the main body part and the overturning part can be welded, or can be connected by other connecting modes such as bolt connection, riveting, gluing and the like; the utility model discloses in the bolt can become tool to lock or other fixed modes.

Compared with the prior art, the utility model, have following advantage and effect:

1. the turning part of the ladder can be turned down and up according to requirements, and the turning part is used as the extension of the main part of the ladder when turned down, so that the distance between the pedal and the ground can be greatly reduced, and people can get on the ladder easily and conveniently; when the automobile is turned over, the side guardrail can be used as a side guardrail by fixing the side guardrail on the main body part through the bolt, so that the automobile is protected, and the damage of collision to the automobile body is reduced.

2. The utility model discloses well ladder overall structure is simple small and exquisite, can reduce the shared space after the installation greatly, and occupation space is little, can be applicable to the high altitude construction car of multiple different motorcycle types.

3. The utility model discloses well spacing piece and the cushion of colliding can prevent that main part and upset part from giving birth to the rigid collision, improves the life of step ladder to spacing piece of colliding also can prevent that the people from getting on or off the bus the upset part of step ladder rocks, makes the getting on or off the bus more safe, convenient.
