The shelf span of the unit is generally within 4m, the depth is within 1.5m, the shelf height of low and high warehouse is generally within 12m, and the shelf height of ultra-high warehouse is generally within 30m (such warehouses are basically automatic warehouses, and the total height of shelves is composed of columns within 12m)
Trlet shelves, as the name suggests, are shelves using tray unit storage, with roadway stacker and other storage and transportation machinery.So what is the tray in the tray shelf?

First, the tray is a relatively simple storage device to carry goods, it is not a container, can not wrap goods in it and play a protective role.
Two, trays can generally be divided into: wooden tray, steel tray or plastic tray, etc.
There are plugs under the pad for the forklift to fork from the lower part and hold the pad for loading and unloading.

Third, because the four sides of the tray is almost open, the stability of the stack is not enough. In order to improve the safety of the work, some other packaging measures need to be taken to ensure its safety.
Generally taken measures to increase stability are: with rope, corner column, steel belt and other things to fix the goods, in recent years, more new materials have been used as contraction package or stretching package.
IV. When loading and unloading goods, pile a single piece of goods on the tray and fix the goods on the tray with shrink film to form a large package, which is often known as "tray packaging". The load weight can be generally be divided into 1 ton, 1.5 tons, 2 tons or 2 tons!

5. When customizing the tray shelf, in addition to the size and weight of the goods, we also need to consider the size of the tray. The customized tray shelf according to the size of the tray can be more suitable with the tray.
