Drive In/Drive Through Pallet Rack

Drive In/Drive Through Pallet Rack Provides High Density Pallet Storage

Drive In/Drive Through Pallet Rack is ideal for storing large quantities of the same product and provides last-in/first-out access for lift equipment using the same entry and exit point for each storage bay. The system allows for a maximized use of both surface area and height. Sets of racks form interior loading lanes. The forklifts enter these internal lanes with the load raised slightly above the level on which it is to be deposited. Each loading lane is equipped with supporting rails for pallets on both sides, positioned at various levels.


All products stored in a loading lane should have the same SKU to avoid unnecessary pallet handling. The depth of each lane will depend on the number of pallets per SKU, the occupied space, and the length of time they will be stored.


Drive-In Pallet Rack

This is the most typical way to manage loads in the Drive-In/Drive-Thru system. The racks act as a storage warehouse. They are equipped with a single access aisle, where loading and unloading occur in reverse order.


Drive-Thru Pallet Rack

The load is managed in this case by using racks as warehouse regulators, with two accesses to the load, one on each side of the racks.


Forklifts enter the storage lanes with the load raised above the level on which it is going to be deposited. The forklifts used in the Drive-In/Drive-Thru system are counterbalanced and retractable types. The forklift deposits the pallet on the Drive-In/Drive-Thru rack by setting its lower runners on the supporting rails. The stress on the lower runners is very high, so the pallets that are used should be in optimal condition.


The pallets can only be placed in the opposite direction when their resistance, rigidity and the weight of the goods allow it. In addition, the forklift’s ability to enter the lane should be checked. If the goods overhang the pallet , the dimensions of the pallet can be different from the measurements of the goods. This will influence the dimensions of the racks and supports. 

Rack stability must be guaranteed, both crosswise and lengthwise.

Longitudinal stability: Stability is ensured through the rigidness of the frames and the diagonal bars and from the fact that the latter are interlocking with each other through the supporting tracks.


Transverse Stability: Perpendicular to the storage lines, the transverse plane is designed with two basic construction systems which guarantee stability through the following means, both of which include top tie beams:


Drive in rack also puts in place horizontal cross bracing along with vertical cross bracing located either at the back of the system (single access) or central to the system (double access).


Drive thru rack includes horizontal cross bracing along with rigidity lanes (dead bay).


Pallet support rails can be bolted or welded.  Bolted rails include both C-type and GP4 type rails.  C-type rails are used when the loads overhang the pallets.  GP4 type pallet support rails enable pallet centering with a minimum loss of space.  There are various types of welded pallet support rails available to fit your needs.
