An electric component factory is a representative of discrete manufacturing industry, and mainly carries out manual assembly and manual transportation to carry out production operation. The small-batch multi-variety is a common scene in the component industry, frequent semi-finished product transferring activities exist between a component line and a general assembly line, and the general assembly line consumes components at a high speed and needs a large number of semi-finished product containers for bearing. To facilitate transfer and save floor space, a chassis transfer cart (a cart having only four wheels plus a bottom surface) is commonly used to transfer a plurality of semi-finished containers, which are stacked together.

The lower containers, being very close to the ground, usually need to be stood down to a low height by the workers when placing the semi-finished containers, while the containers are heavy, which is an ergonomic violation in the industrial field and risks to the workers. In addition, when the assembly line worker takes the semi-finished product on the lower layer, the assembly line worker needs to move to the working table first, and the problems described above are also encountered. This has a higher safe and healthy risk to the workman's operation, and simultaneously because increased work load, work efficiency also can descend along with it.

After the upper containers are used up, an empty area is required to store the containers. Due to the large number of such transfer trucks and semi-finished containers in the production plant, this has a great influence on the area utilization of the production area, increasing the production costs. When semi-finished products are loaded, empty containers need to be moved to an empty place, then the containers are respectively filled, and the containers are respectively conveyed and loaded on a vehicle.

When the whole vehicle is transported, a person bends the waist bow to carry the vehicle back, lightly pushes the stacked boxes with hands to move forward, and if the force is too large, the stacked boxes can collapse. Therefore, the whole transportation efficiency is low, and meanwhile, due to the fact that the operation posture is not firm, certain safety and health risks are brought to the operation of workers.
