They are widely used in multiple industries such as construction, manufacturing, mining, aviation, shipping, and logistics. The following is a detailed introduction to cranes: Working Principle The working principle of a crane is based on electromagnetic induction and the lever principle. When the lifting motor is powered on, a magnetic field is generated, and the rotor cuts the magnetic force lines to make it rotate, thereby driving the hoisting mechanism to work. At the same time, the crane uses the lever principle to balance the counterweight and the suspended weight, and decelerates and increases the torque through a fixed pulley block to achieve the purpose of lifting heavy objects.

[0003] During the use of a crane, a fixed base is required for fixation. However, in the current use of the fixed base, only a square plate is used for support and fixation, and the fixation effect is relatively poor. During the load of the crane, the crane is prone to instability, and the safety is relatively poor, which is not convenient for users to use.

[0004] Therefore, it is necessary to design and transform the fixed base to effectively prevent the phenomenon that only a square plate is used for support and fixation in the current use of the fixed base, resulting in a relatively poor fixation effect, the crane being prone to instability during the load of the crane, and relatively poor safety.
