Driver in storage rack is the forklift into the out of the shelf, the tray unit for storage operations of the assembly rack. Also known as corridor-style shelves, through-type shelves, is the use of lattice-type column side of the way to connect the multi-door, the pallet unit of goods along the depth of a close to a storage on the cantilever in the form of shelf structure. Because of its own structural characteristics, the entry-shelf system has many requirements such as storage of goods, rated load and maximum load, material, structure, size, strength, stiffness and stability in the design and planning process.
The United States warehousing shelves into the shelf design, the standard has the following:
1. Pallet unit of the goods into the shelf of the warehouse planning plan is the first tray of goods standard goods, based on the card board to carry the cargo to consider, it is recommended to use double-sided card board. The weight of the pallet unit should normally be controlled within 2000 KG. Due to the large storage density of the pallet units of the entry-type shelves, the operating channel and the storage space are combined so that the entry-type shelves have higher requirements on the quality and external dimensions of the trays relative to other shelves.
2. The structure of the entry-type shelves At present, through the use of WAP shuttle trolley to replace the forklift out of the roadway entry-type shelf mode, the main structure of the shelves are a number of statically indeterminate space steel structure.
3. The basic size of the entry-type shelf design is the pallet-oriented tray width dimension, which is one of the important parameters of the entry-type shelf design, which directly affects the other dimensions of the shelf and the operable space of the forklift;
W1 is the effective distance of the forklift, directly determine the width of the forklift body (usually forklift body width is less than W1-100mm);
W2 is the distance between the center lines of the adjacent two columns;
W3 is the effective length of the cantilever; the greater the length, the greater the bending torque of the column, the same specifications of the pillar bearing capacity of the smaller, that is, the impact of cargo, the general W3 ≥ 210mm;
W4 for the tray in the cantilever mounted on the size, related to the tray access to the security process, the general W4 ≥ 130mm;
W5 is the gap between the goods and the column, affecting the safety of the goods on the column and the general W5 ≥ 75mm.
