During use, horizontally rotate the driving beam 2 along the driving beam pivot 41, and move the driving carriage 3 along the direction of the driving beam 2, so that the hook 31 of the driving carriage 3 can be pulled to the top of the hanging object quickly. That is, the hook 31 can be used to lift the heavy object; then the heavy object can be moved to the desired position by the rotation of the driving beam 2 and the operation of the driving beam 3 along the direction of the driving beam 2, and finally the heavy object can be unloaded, thereby realizing lifting and Unload the heavy objects to be transported, effectively improve the lifting capacity of the production workshop, and solve the problem of shortage of lifting resources in the production workshop. The utility model has a simple structure, convenient installation, and reduces production costs.

The hoisting range of a simple driving movable arm described in the present invention is the space area covered by the rotation track of the driving beam 2 . During the production process, multiple simple traveling arms can be installed on the factory frame column 1 of the production workshop, so that the hoisting range of all simple traveling arms covers the entire production workshop, which can not only ensure effective hoisting in the production workshop, but also because of the simplicity of each The three arms of the crane do not interfere with each other, which is conducive to improving the utilization rate of the production site and the lifting efficiency.

In this embodiment, the driving beam rotating frame 4 includes a base 42 protruding from the outer wall of the frame column 1 , and the upper and lower ends of the driving beam pivot 41 are fixed to the base 42 .
