High-Density Drive-In Pallet Racking Systems Working Procedure For
Warehouse Storage
In a drive-in pallet racking system, multiple pallets are stored on
rails that are perpendicular to the main aisles on a
Last-in/First-out(LIFO) basis. These continuous rails, as we have
mentioned before, are supported by single or double corbels
connected to the upright frames, where pallets can be placed or
picked by forklifts.
In another word, the forklifts have to drive into the structure to
load and unload pallets. With this special operation process, there
are some design criteria that are worth your attention.
Specifications of Drive-in Pallet Racks
| Name | Drive-in pallet racking system |
| Color | RAL color system, customized |
| Loading weight | 1000kg-2000kg per pallet, customized |
| Material | Roll-formed Steel |
| Characteristic | First in-Last out(FILO) |
| Standard accessories | Safety protectors, bolts, nuts, safety pin |
| Components | Upright frame(upright, horizontal bracing, diagonal bracing),
beams, pallet rails |
First of all, the dimensions of the pallets (width, depth, height)
should be considered when the rails are engineered. Please make
sure that the pallets would not fall from the rails by setting
proper clear between rails and upright frames, as well as choosing
the right size for the arms to accommodate specific pallet width.
Loaded from the back to the front, products on pallets must be
positioned on rails safely and precisely by the proper lift truck,
which is compatible with the rack system.
To be specific, you should make sure that the vehicles used can
enter the racking system with appropriate clearances between
uprights and ground rails. And the depth and height of the system
are based on the layout of the building and the type of forklift
being used. Particularly, the forklift’s maximum lifting height
should cover the highest rail level for satisfying storage and
retrieval.
Since forklifts enter and exit the structure frequently, giving
additional protection will reinforce the system’s impact
resistance. For example, you could use more robust columns and base
plates, rub ground guide rails and reinforced upright protectors,
etc.
Theoretically, the depth of the lane is unlimited but usually, max
10 pallets deep are recommended for activity efficiency. However,
for safety concerns, the design of the 10 pallets' deep drive-in
rack is more likely to go for the dual-entry system with five
positions each placed back-to-back, instead of the single-entry
pattern. In this method, the distance a forklift must travel in the
rack has been reduced a lot, thus decreasing the chance of
collision or potential danger.
