Characteristic of through shelf:
1. Goods follow the first-in-first-out principle and are suitable for storage and operation of most transshipment machinery.
2. On the support rail, the pallets are stored in depth order to achieve high density storage.
2. Goods enter from the same side of the shelf and are stored before they are taken. Forklift trucks can easily drive into the middle of the shelf to pick up goods without occupying multiple channels to facilitate the entry and exit of goods.
4. This kind of shelf is suitable for the storage of large quantities and small varieties of goods. The bracket and bracket shelf of through-type shelf adopt integral stamping/rolling technology, which has strong bearing capacity and beautiful appearance.
5. The total depth of through-shelf is usually best controlled within 5 pallet depths. The total depth of the middle area can be controlled within 10 pallet depths to improve the power and reliability of forklift truck.


Planning and design elements of through shelf:
1. Logistics direction and requirements of warehouse area
2. Plane standard and effective height of storage area
3. Pallet unit cargo standard (long L width W high H)
4. Weight of pallet unit cargo (including pallets)
5. Selection of forklift type or parameters
Continuous shelf maintenance:
(1) After the impact of external forces, the safe and stable shelf components should be replaced in time. According to the principle of safety first, the hidden safety hazards in the cleaning process should be found in time and handled in time to ensure safe and efficient storage.
(2) Correct use of professional level stereoscopic positioning, accurate record of shelf status, so as to carry out beneficial correction, ensure shelf capacity and safety.
(3) Strictly implement the safety operation, no overload, over-line location, over-storage density and other provisions to ensure the safety function in the storage process.
(4) The maintenance cycle is one year.
(5) Maintenance includes routine contents such as tightness measurement of fasteners, vertical measurement of Posts and measurement of damaged parts. If the column is impacted, bending (fracture) needs to be determined. System maintenance based on measured data.

Scope of application:
Because of the relatively low investment cost, the through shelf is suitable for large transverse size, small variety and large quantity. It is usually used to store large quantities of goods of the same type. Because of its high storage density and high utilization of ground space, it is often used in warehouses with high cost of storage space, such as refrigerators, food, tobacco, etc.
