What are the structure and design points of selective pallet racking?

Selective pallet racking is used to store unitized pallet goods with aisle-type stacker cranes and other storage and transportation machinery for operation. High-level racking mostly adopts integral structure, which is generally made of steel sections welded shelf pieces (with pallets), linked by horizontal and vertical ties and crossbeams, and other components. The following is an introduction to the structure and design points of selective pallet racking.

Structure

With flat pallets, the goods between the two pallets and the lowermost layer will be squeezed, even causing damage to the goods, and this stacking method cannot be done first in first out. When each pallet is loaded with different goods, it can only be single, not stacked, resulting in a lower storage capacity. Such as the use of column pallet or frame pallet, although you can stack so that the goods are not squeezed, the stacking cannot be too high, too high too thick stability is poor, not safe.

Therefore, with the use of selective pallet racking, each pallet occupies a cargo space, which can overcome the above-mentioned problems. Higher selective pallet racking uses stacking cranes to access the goods, and lower selective pallet racking can be used to access the goods by forklift. Selective pallet racking can realize mechanized loading and unloading operations, facilitate unitized access, high utilization of storage capacity, improve labor productivity, realize efficient access operations, and facilitate computerized management and control.

The most common type of selective pallet racking has the advantage of easy access and high picking efficiency. However, the storage density of this type of racking is low and more aisles are required. According to the width of access, the aisle can be divided into traditional type aisle, narrow aisle, and ultra-narrow type aisle. This type of shelving is suitable for the storage of goods of medium volume and general volume. Usually below 6m, the number of layers to 3 to 5 layers is appropriate. In addition, it can be adjusted to any combination, construction is simple, economical, in and out of the warehouse is not affected by the sequence, the general forklift can be used. When choosing selective pallet racking, the size, quality, and several stacking levels of the storage unit should be considered to determine the size of the columns and beams. Selective pallet racking is a general pallet stacking method with one beam opening to store two pallets.

The role of the back connection bar

This connecting rod is used to connect two rows of racks back-to-back to increase the overall rigidity. The goods are 1150mm long and the width of the column is 1000mm, if you choose an l00mm connecting rod, the goods will stick out of the shelf, so it is appropriate to choose a 300mm connecting rod.

The distance between the upper beam of the shelf and the ceiling

The maximum height of the forklift will exceed the upper beam of the shelf by more than 200cm, and there is at least 30era clearance between the maximum height of the forklift and the ceiling. For this reason, the distance between the upper beam of the shelf and the ceiling is required to be 230cm or more.

Criteria for the selection of the support column

The load-bearing capacity of the shelf is determined by the load capacity of the lowest level. The load capacity of the lowermost pillar is 6000kg, and the pillar is selected differently when the height of the lowermost beam is different.
