[0027] The foot wheel 7 is mounted at the bottom of each bracket 2.

[0028] Through the above technical scheme, two foot wheels 7 are mounted at the bottom of each bracket 2. The whole transfer tooling considers that there are two brackets at both ends of the CT scanning frame, and there are a total of four foot wheels 7, which provides stable support and moving ability for the tooling.

The AGV steering wheel is a composite wheel set that integrates a drive motor, steering mechanism and braking system. It can not only provide sufficient driving force to move the load, but also achieve 360-degree all-round steering, and realize precise control of the travel path and direction.
