For large sterilization cabinet, main purpose is to reduce the product into or out of the sterilization cabinet workload, this equipment adopts caterpillar flexible rotation to drive tray before and after the move, and tracked inside the equipment for rolling friction, it is easy to start you can configure the inverter or servo motor smooth acceleration deceleration of the smooth start, stop, so the motion stability is better, is implemented in the front-rear door at both ends with power conversion mechanism, the external driving force (servo motor) conversion to the internal automatic transmission line, so as to realize the automatic transmission of the product.
