[0002] A construction project refers to an engineering entity formed through construction activities such as new construction, reconstruction, expansion, repair or demolition of various buildings and structures. Generally, in the stages of main structure construction, construction material transportation and installation of equipment used in construction, in order to speed up the progress of the project, corresponding lifting equipment is often used instead of manual handling of various heavy objects.

[0003] The existing utility model with authorization announcement number CN219906782U discloses a small lifting equipment for construction projects. The extension length of the telescopic boom can be adjusted according to the volume of the hoisted heavy object and the distance between it and the small lifting equipment for construction projects in this embodiment to facilitate lifting. At the same time, the extension length of the telescopic legs can be adjusted according to the extension length of the telescopic boom and the lifting weight to prevent forward tipping during lifting and ensure the stability of lifting. By adjusting the position of the upper end of the diagonal rod between the adjustment holes, the telescopic boom can be tilted upward to increase the lifting height. When the lifting work is completed, the installation between the diagonal rod and the adjustment hole can be removed, and the boom can be folded to reduce the overall storage space.

[0004] Although the above technical solution can be adjusted in multiple directions and increases the application and storage scenarios, the above technical solution lacks an overload warning structure, which makes it easy for safety accidents such as damage to the lifting structure to occur when lifting overweight goods.

[0005] Therefore, those skilled in the art provide a multi-adaptive lifting device for construction engineering to solve the problems raised in the above background technology. Utility Model Content

The back of the storage shell 401 is fixedly connected to the outer surface of the multi-directional adjustment frame 2, and the bottom surface of the counterweight base 1 is fixedly connected to four connecting columns 5. The bottom end of each connecting column 5 is fixedly connected to a universal wheel 6. By setting the connecting column 5, the counterweight base 1 and the universal wheel 6 can be connected. By setting the universal wheel 6, the movement and transportation of the entire lifting equipment are facilitated.

By setting the push handle 7, it is convenient to push the entire lifting equipment for movement and transportation by manpower and labor saving in combination with the universal wheel 6. By setting the anti-slip cover 8, the hand-gripping anti-slip property of the outer surface of the push handle 7 can be increased.

[0026] The interior of the storage shell 401 is slidingly connected with a slider 406 and a top plate 408, the upper surface of the slider 406 is fixedly connected to the bottom surface of the limiting double-wheel frame 402, and the inner bottom wall of the storage shell 401 is fixedly connected with a pressure sensor 407.
