[0002] A cantilever crane is a type of equipment that can be used for short-distance, frequently used, and intensive lifting operations. It is not only unique in structure and safe and reliable, but also has many characteristics such as high efficiency, energy saving, time-saving, labor-saving, and flexibility. The column of the cantilever crane, as the main component of the cantilever crane, plays the role of supporting and fixing the cantilever crane components. During the long-term use of the column, due to the pressure of lifting some heavy objects, it will easily cause the fixing components installed at the bottom of the column to loosen, causing the column to tilt, affecting the installation and lifting use of the cantilever crane. Therefore, a reinforcement device is needed to provide auxiliary support and reinforcement for the column of the cantilever crane.
[0003] When the column reinforcement device of a cantilever crane is used to reinforce the crane installation column, most of the time, the two sides of the column are simply and directly reinforced. However, the cantilever is rotatable when working at the top of the column, which makes the force direction of the column not only on both sides, but also in different rotation directions. The simple reinforcement on both sides has a poor stabilization effect and is insufficient, making it inconvenient to support and reinforce the crane column.
