Through-type shelves are also called corridor-type shelves,and the through-type shelvesadopt the tray access mode,which is suitable for the storage of goods with small variety andlarge quantities.Through-shelves Since the forkift needs to access the intenior of the rack toaccess the goods,it is generally recommended that the single-sided pickup should notexceed 5 rack depths.Through-shelf storage capacity in the same space is almost doublethe capacity of conventional pallet shelves,because the roadway between rows of shelves iscancelled and the shelves are merged so that the goods in the same floor and the same roware connected to each other.Limit the utilization of storage capacity.Through-type shelvesare widely used in the storage of large-lot,less-variety goods.These types of goods arepackaged in a unified manner and have a single product,such as food,tobacco,coldstorage,and other warehouses.

Column piece: Two columns are made of cross struts anddiagonal braces with nylon self-locking bolts, which caneffectively prevent shelves from destabilizing after loosening ofbolts. There are double rows of diamond-shaped holes punchedon the columns, and the hole spacing is 75mm,so the beam isattached. The height can be adjusted up and down in 75mmunits on the column.
Top and back beams: welded by two column cards andrectangular tubes, this structure has the characteristics of simpleand reliable, light weight, bearing pull, strong pressure, and lowcost. When the column card is connected with the column, it isequipped with special design safety pins to ensure that the beamdoes not fall off after the external force hits.
Bull legs:for the overall stamping forming components, there arewelding cow legs, optional, with a large moment of inertia, strongbearing capacity,beautiful appearance, etc., and the column isconnected with a special design safety pin, can ensure that thebeam is not impacted after the external force Will flloff.
Shelf: for cold rolled parts, any length can be made according toneed,no joints, beautiful structure,even force.

The design of through type shelves pays special attention to size:

A. Shelf length (size from column center to center)
B. Inner diameter of pillar or corner guard (pay attention to forklift width)
C. Shelf width (column size)
D. The length of the pallet and the size of the fork determine the length of the shelf
E. Inner diameter between cow legs (pay attention to the width of the upper part of the forklift)
F. The size of the tray occupying the shelf (pay attention to load-bearing and safety)
G. Column spacing (usually the width of the pallet)
H. Shelf height (pay attention to pallet height, cargo height, lifting space, etc.)
