This equipment is an important device for storing and transporting nuclear fuel rods. The loader has full vehicle servo control, and the lifting and operating mechanisms have high-precision positioning functions. Plane positioning accuracy: ± 1.5mm, lifting positioning accuracy: ± 1mm. The loading function is fully automatic, capable of automatically addressing 260 positioning points and loading and unloading items. The redundant design of the large and small car operation and lifting mechanism ensures that the working motor coexists with the backup motor, and any motor can operate independently without stopping. The operation and lifting mechanism of the large and small vehicles are equipped with manual operation devices to ensure that all tasks are completed manually in the event of a power outage in the entire vehicle. In order to prevent nuclear fuel leakage, the loader comes with an anti radiation storage room, allowing nuclear fuel to be transported in a closed environment.
