The drive-in rack is an innovative solution for storing large quantities of uniform pallets. This racking system does not involve aisleways, which boosts the overall warehouse efficiency by 4-6 times and provides a larger storage capacity for the drive-in rack system as compared to the pallet rack system. The equipment drives in for loading and unloading of materials.
Due to the following technical parameters and configurations, these systems offer a convenient solution for both a single warehouse and a large logistics centre:
- for placement of goods with uniform characteristics, a low turnover rate, and a long shelf life;
- storage capacity optimization by 70-80%.

The drive-in deep rack is a prefabricated demountable metal structure for storing loads on pallets. It consists of vertical frames, the same as used for pallet racks, a system of ties and a guiding girder. Drive-in racks are the best solution if your warehouse has limited space and stores uniform goods. Their primary advantage is a large storage capacity. The name “drive-in racks” describes the specifics of the system operation: there are no aisles between the installed racks, and the loading equipment does not have to go inside the aisles. It is important to carefully selectthe warehouse equipment for the maintenance of a drive-in rack system.
Depending on the installation choice, the drive-in systems can have:
- One-way (drive-in) loading and unloading: the warehouse operates on a LIFO basis — «last-in-first-out»; to put it simple, the process of loading and unloading of goods is carried out on one side. This system has been used in warehouses intended for the simultaneous storage of large amounts of long-time storage goods.
- Two-way (drive-through) loading and unloading: the warehouse operates on a FIFO basis — «first-in-first-out», which means that the first loaded pallet will be unloaded first. This “drive-through” solution is the best choice for warehouses storing goods with limited shelf life.
The loader or stacker drives directly inside a drive-in rack passageway and places its loads. Therefore, there are some requirements for the loading equipment to be used, and for the racking system design.
А — Overall width of the loader.
The minimum clearance of B mm on each side between the loader and vertical elements of the rack is required.
Dimension C is a distance measured between rack posts.
G — Width of the loader operator’s protection.
H — Minimum distance between cradles.
The minimum gap between the cradle and the operator’s protection is 50 mm.
D and E — Base height and protection height of the forklift.
F — Maximum lifting height.
It must be at least 200 mm larger than Dimension I.
K — Height of the lower and intermediate levels.
K = Pallet height + 250 mm.
L — Height of the upper level.
L = Pallet height + 200 mm.
M — Overall height = Total of all levels.
Dimensions K, L and Mcan be adjusted with a 75 mm increment.
N: the overall depth of all pallets (including the dimensions of a cargo if it projects) plus clearance for positioning within the range of 35 mm to 50 mm per pallet, depending on the number of pallets (the more pallets, the more clearance required).
The passageway width is determined by the front pallet size plus the minimum required clearances. If a cargo overhangs from the pallet, the passage must be wider and the brackets must be longer because even if a pallet is fully displaced to one side, the minimum pallet support of 50 mm must be provided
The minimum clearance is 75 mm. We recommend to increase this parameter for high pallets. The table gives the main standard parameters for 1,200 mm wide pallets. The same criteria should be applied to pallets of other sizes.
– A vertical element of a metal structure built on two posts connected by a system of horizontal and diagonal ties.
The posts are perforated to enable adjustment of the height of storage tiers.
The frame is assembled with bolted connections.

Method of assembling a foot and fastening it to the floor with expansion anchors.
The foot serves as the frame base and is bolted to the floor; auxiliary adjusting plates are used for uneven floors.
Method of fastening braces to the frame.
Coating: powder paint, colour — orange RAL 2004, gloss.

Prevents posts from damage by loaded pallets when moving along the channel.
Braces fasten the rack posts from top to bottom. Elements are bolted to the frame, ensure structural stiffness and reliability, as well as optimal load distribution.
The upper beams are stiffening elements and serve as a bonding frame for the entire racking structure of a drive-in rack.
