China Best Drive In Racking System Factory & Supplier

Selective pallet racking requires dedicated 3.0m to 3.5m forklift operating aisles between every back-to-back rack run, dedicating up to 60% of total facility floor space to vehicle circulation. Drive-In racking eliminates these intermediate aisles entirely. Pallets are staged continuously on side-mounted support cantilever rails inside open lanes. Forklifts enter the actual storage block along floor-mounted steel guide tracks, condensing storage into a solid block with space utilization reaching 75% to 80% of total warehouse floor volume.

Yes. Our engineering department designs storage systems with reference to AS 4084 (Steel storage racking) principles, providing comprehensive section properties, beam and rail deflection calculations, and floor-anchor shear calculations. For New Zealand projects, we calculate dynamic seismic coefficients referencing NZS 1170.5 parameters, engineering reinforced base plates, heavy-duty floor anchoring, and enhanced cross-aisle portal bracing suitable for local certified engineer review and building consent sign-off.

Proper drive-in engineering requires precise coordination between pallet dimensions and forklift physical geometry. Generally, a minimum total clearance of 75mm to 100mm is maintained between the outer edge of the pallet and the inside face of the upright column on each side. The overall width of the forklift truck chassis and mast must be narrower than the clear dimension between the cantilever pallet support rails (typically requiring 100mm to 150mm total vehicle operating clearance). Floor guide rails are installed to mechanically steer the truck along the center of the lane, preventing driver drift.

Because forklifts enter the interior of the rack structure, the front entry columns face elevated strike risks. HEDA employs a triple-protection safety design: First, the front uprights are fitted with reinforced steel wrap-around column guards or heavy cast-iron protectors bolted directly into the concrete slab. Second, heavy continuous steel angle guide rails line the floor throughout the entire lane, equipped with flanged flare horns at the lane entrances to funnel the forklift smoothly into the bay. Third, we offer reinforced double-upright columns at entry portals where two roll-formed omega profiles are welded back-to-back for double section modulus strength.

Due to the concentrated mass of high-density drive-in storage, concrete slab loading is substantially higher than in selective rack installations. Concrete floors must be engineered to a minimum compressive strength of 25 MPa to 30 MPa (3,600 to 4,350 psi) with an uncracked reinforced thickness typically between 150mm and 250mm, depending on rack height and pallet weights. Floor flatness should meet DIN 18202 Table 3 Line 3 or ASTM E1155 F-min 50 standards to avoid mast sway at upper storage levels. HEDA provides comprehensive column point-load calculations so your civil engineer can verify soil and slab suitability.

Standard manufacturing lead time ranges from 15 to 25 days following engineering drawing sign-off and deposit receipt. Shipping from our Guangzhou/Shenzhen port facilities provides direct sea-freight transit times of approximately 12 to 18 days to Australia/New Zealand, 20 to 28 days to Western Europe, and 18 to 25 days to the US West Coast. All components are packed on custom steel frames and strapped to prevent maritime transit vibration damage, complying fully with international container loading regulations.
