Drive-In / Drive-Thru pallet rack systems are a cost-effective solution to high-density storage. This static system has rails running the depth of the rack for pallet placement. The only limitation to the depth of pallet storage is the capability to drive deep within the system. The rack depth reduces the need for aisles and drastically increases cubed space utilization.
Drive-In systems load and retrieve from the same side, creating Last-In-First-Out (LIFO) inventory retrieval organization.
Drive-Thru systems load from one side and unload from the other to create First-In-First-Out inventory retrieval. Forklifts can enter from either aisle. The rigidity of Drive-Thru racking is a result from its overhead bracing or from being tied to the overhead structure. It is an excellent option for freezers, providing low cost bulk storage along with guaranteed stock rotation.
Systems are easy to install with simple support arms to hold rails and can be attached to standard pallet rack or special structural designs. UNARCO Engineering has specially designed sloped-leg frames to add extra clearance and safety for forklift movement within the aisles. This greatly reduces the risk of impact damage to front posts and allows drivers to swing loads as they exit the rack.
