[0002] Container port tire crane, also known as mobile container gantry crane, is a special machine used for container stacking operations at container terminals. This equipment has the functions of lifting, unloading and short-distance transportation, and can quickly and accurately move containers from one location to another, thereby greatly improving the loading and unloading efficiency of port terminals.

[0003] During the continuous use of the tire crane, the tires need to be replaced and repaired regularly. Due to the heavy weight and large size of the tire crane tires, it is very inconvenient to replace them. In the past, when replacing tires, the tires were forked to one side by a forklift, and the forklift and the person worked together to flip the flat tires to an upright state. After the person held the tire in place, the forklift forked the upright tires to the replacement position. Because the tires are very heavy, it is extremely inconvenient for maintenance personnel to operate, and the tires may also roll over, even causing injuries. In addition, the forklift is a motor vehicle, and it is difficult to ensure the positioning and fixation during the installation process, which poses certain safety hazards.

[0004] To solve the above problems, the patent with announcement number CN110027726B discloses an auxiliary device for replacing aircraft tires, including a trolley base, wheels, a main bracket, a lifting bracket, an "L"-shaped bracket, rollers, pressure rollers, a camera, a camera mounting plate, a wheel control motor, a pitch rotation driver, a first lifting driver, a second lifting driver, a third lifting driver, a lateral movement control motor, a locking rotation control motor, a controller and a remote control receiver.
