·  Transfer the turnover box loaded on the turnover car by means of foot lever. After releasing the pedal, the fluent bar     tilts, which is convenient for the turnover box to enter the turnover car. One-way check pieces are configured at the   end to prevent the entering turnover box from slipping off the turnover cart.

·  Make the turnover box loaded on the turnover car parked in front of the shelf, after stepping on the pedal, the turnover car's fluent bar tilts up, turnover box moves, under the action of folding connector, after putting feet, the fluent bar still keeps tilting.

·  After the turnover box is moved to the shelf, release the pedal and reverse the flow bar to enter the state of waiting for the new turnover box

·  After entering the revolving box, the revolving box will not slide under the action of the anti-reverse parts.

Through the special dynamics simulation and according to the actual use condition, make the exclusive scheme.
