In the purchase of the tray, the tray has two-sided and double-sided options. For single-sided or double-sided trays, the storage and handling equipment and status (such as library type, shelf type, stacking code or placement) should be selected according to the corresponding storage, loading and unloading equipment. State) etc. to determine.
Static load refers to the maximum weight that can be followed by the lowest plastic pallet in the stack. The general light series pallets can bear 1 ton, the standard series pallets can bear 4 tons, and the heavy-duty series pallets can bear 6-8 tons; the shelf bearing refers to the maximum weight allowed when placing the plastic palletized goods on the shelves.
It is necessary to pay attention to the difference between dynamic load, static load and shelf load. The difference in load capacity is closely related to the shelf structure, ambient temperature and storage cycle. Generally, the standard series of trays have certain requirements for deflection. The national standard for deflection is 30 mm, but this standard is obviously wider. Hagris recommends using plastic pallets with a deflection of no more than 20 mm on the shelves. If it is an auto-stereo library, the requirements for deflection are more stringent.
For small-scale auto-stereoscopic or high-bay racks, where stacker or electric forklifts are mainly used for vertical transport, double-sided heavy-duty series trays and single-sided standard series trays are available.
