There are three main types of cranes used in construction projects, namely wheeled cranes, crawler cranes and tower cranes. Since tower cranes are directly fixed on the horizontal surface, load-bearing devices are required to install the lifting equipment when wheeled cranes and crawler cranes carry heavy objects.

For example, in a supporting device for a construction crane with the publication number CN217051324U, the base, slide rails, load-bearing seats, load-bearing plates, load-bearing columns and load-bearing beams are all made of steel, which is heavy and easy to ensure the stability of the supporting device. The device is not easy to tip over when carrying heavy objects; the second hydraulic cylinder and foot plate can be lowered to touch the bottom, adding support points, which enhances the stability of the entire device; the mobile component can move the entire support in the horizontal direction device, which can increase the scope of transporting heavy objects.

The load-bearing device of the above-mentioned lifting equipment still has the following shortcomings in actual use: when lifting operations are required, the hydraulic cylinder needs to be opened to drive the foot plate to move downward until the foot plate contacts the ground, which can increase the support fulcrum. For the purpose, if a mobile component needs to be used to drive the load-bearing device, the foot plate in contact with the ground will affect the movement of the load-bearing device, so the foot plate needs to be retracted to move the load-bearing device, but this will cause the lifting of the upper part The stability of the equipment is reduced, so a load-bearing device for the installation of lifting equipment is needed to solve the above problems.
