Abstract

The invention discloses a wheeled crane frame and a wheeled crane. The wheeled crane frame includes a box structure. The box structure includes an upper cover plate, a lower base plate, and a left web and a right web; at least one of the left web and the right web includes a non-planar plate, and in the cross section of the box structure, the non-planar plate is configured as The cross-sectional area of ​​the box-shaped structure is larger than the cross-sectional area of ​​the quadrilateral enclosed by the straight lines between the first upper connection end, the second upper connection end, the second lower connection end and the second lower connection end. In the wheeled crane frame of the present invention, the web forming the box-shaped structure is constructed as a non-planar plate so as to increase its cross-sectional area, thereby improving the bearing capacity of the wheeled crane frame. Moreover, compared with the prior art, further weight reduction can be achieved on the basis of ensuring a certain carrying capacity.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a wheeled crane frame and the wheeled crane. Background technique [0002] As the lifting performance of the crane is gradually improved, the length of the boom of the crane will increase, and the weight of other structural parts will also increase. For the chassis frame, it is necessary to meet the requirements of lifting performance improvement and light weight, but the improvement of lifting performance and the realization of light weight are contradictory. [0003] The vehicle frame in the prior art is usually a box-shaped structure. In order to achieve weight reduction, the traditional method is to increase the size of the box structure and reduce the plate thickness. However, due to the limitation of vehicle width and the layout requirements of other chassis components, the cross-section of the frame cannot be increased indefinitely, which makes it difficult...
