The load weight of each tray should be less than or equal to 2 tons. In order to ensure safety in transit, the height of the center of gravity of the goods carried should not exceed two-thirds of the tray width.
According to the type of goods, the quality of the goods carried on the tray and the size of the tray, reasonably determine the way the goods are placed on the tray. The bearing surface area utilization rate of pallets should generally not be less than 80%.
For pallet cargo placement has the following requirements:
1, Wood, paper and metal containers, such as rigid straight square cargo single-layer or multi-layer staggered placement, tensile or shrinkage film packaging;
2, Paper or fiber goods single-storey cargo multi-layer, with strapping belt cross sealing.
3, Sealed metal containers and other cylindrical cargo single-layer or multi-layer placement, wooden cargo cover reinforcement.
4, Need to carry out moisture-proof, waterproof and other protection of paper products, textile goods single-layer or multi-layer staggered placement, stretching or shrinkage film packaging goods to increase angular support, cargo cover partitions and other reinforcement structure;
5, Fragile goods one-way or multi-layer placement, increase the structure of wood support diaphragm.
6, metal bottle cylindrical container or cargo single-layer vertical placement, increase the frame and strip reinforcement structure;
7, Bag goods multi-layer staggered compaction yards.
Pallet bearing cargo for the fixed way mainly strapping, gluing binding, tensile packaging, and can be used with each other.
After the pallet bearing cargo is fixed, still can not meet the transport requirements should be selected according to the needs of protective reinforcement accessories. Reinforcement protection accessories are made of paper, wood, plastic, metal or other materials.
1, Single-sided plastic tray can only be used on one side, the surface has grid-like peace plate two, the bottom has Chuan-shaped, field-shaped, nine-foot type.
2, double-sided plastic tray refers to the front and reverse sides of the tray structure is the same, the surface has a mesh and peaceful plate two, both sides can be swapped for use. The choice of single-sided tray or double-sided tray, should be based on the corresponding storage, loading and unloading equipment and status (such as library type, shelf type, heap code or placement status, etc.) to determine.
3, dynamic load refers to the pallet in the use of motorized forklift or manual hydraulic pallet truck, the maximum weight that can be carried in motion (within 1.5% of the bending degree is normal).
4, static load refers to in the heap code, the bottom of the plastic tray can withstand the maximum weight.
5. Shelf bearing refers to the maximum weight that can be sustained when the plastic tray containing the goods is placed on the shelf (within 1% of the bending degree is normal). General Standard Series tray in the shelf load can bear 0.4t~0.6t, heavy load series tray can load-bearing 0.7t~1t.
1, Hydraulic vehicles and forklifts in the use of pallets in the process, the distance between the fork teeth should be relaxed as far as possible to the outer edge of the tray, the depth of the fork should be greater than 2/3 of the depth of the entire tray.
2, Hydraulic vehicles and forklifts in the use of pallet movement, should maintain a uniform speed and up and down, to avoid sharp brakes, sharp turn caused by damage to pallets, resulting in the collapse of goods.
3, Tray on the shelf, should keep the tray on the shelf beam on the smooth placement, tray length should be greater than the shelf beam outer diameter of more than 50mm.
