To understand storage shelves bear the weight of the goods is to rely on what parts, first must know the structure of the shelves, shelves usually consists of four kinds of structure: beam type, through type structure, the structure of the cantilever structure and the layer board. Other types of shelves are all based on these structures.

Columns are the main components all storage shelves, also is the main stress components. Column vertical to the ground, it is the vertical stress components, is also a major part of the goods under gravity. Whatever the type of shelves, cannot leave the columns, two columns and two pillar of lateral brace and a number of root of brace, so can also be the uprights as under the vertical stress components. With shelves carry weight changes, the column material has been changed, the bearing, the greater the stud material is more thick.

Beam type shelf structure, the beam is one of the main parts under gravity, beam shelves is mainly composed of beam and column, according to the actual demand will be equipped with cross beam and the grid board, plywood, cross beam and the grid plate, under pressure from the goods same layer board;

Through type shelf structure, the bracket is a major part of the stress, the bearing beam structure is better than;

Cantilever racking arm is a major part of the goods under gravity, with the increase of bearing bracket and pillar of material will increase;

Layer board shelves in addition to the beam and column, the floor board is also the main mechanical parts, in the process of actual use, the goods is directly on the layer board.

Shuttle car, automated stereoscopic warehouse, loft-style shelves, etc are generally in the storage shelves structure evolved on the basis of above, these types of storage equipment parts similar to the above four kinds of structure under gravity shelves.
