China Wholesale Rack Push Back Manufacturer & Supplier

Push back pallet systems engineered by Guangzhou Heda Shelves are normally configured from 2 to 6 pallets deep per lane. Nominal load capacities span from 500 kg to 1,500 kg per pallet position (up to 9,000 kg total lane payload). Because each nesting carriage requires dedicated vertical rail drop, 5-deep and 6-deep lanes require slightly higher clearance per tier (approximately 150 mm to 220 mm of vertical cart height) compared to 2-deep layouts.

Yes. Our structural design team calculations reference the fundamental limit state criteria of Australian Standard AS 4084:2023 (Steel Storage Racking) and New Zealand NZS 1170.5 structural design actions. We generate section properties, beam load capacity plaques, baseplate anchoring shear calculations, and frame bracing schemas. These comprehensive data packs can be handed directly to your locally certified CPEng engineer or municipal certifier for formal project sign-off.

Standard counterbalance forklifts and conventional reach trucks are fully capable of serving push back systems. Unlike drive-in racks, the forklift never enters the rack structure; the vehicle remains stationary in the operating aisle and pushes the pallet horizontally into the lane. The only requirement is that the forklift mast must provide sufficient tractive force to push the combined weight of the nested pallets up the slight 2% incline during loading.

For cold storage and blast freezer warehouses operating at temperatures down to -30°C, we specify low-temperature synthetic hydrocarbon lubricants within dual-shielded deep groove ball bearings. Standard petroleum grease freezes and creates severe drag, causing cart hesitation. Furthermore, our sub-zero carts are fabricated with cold-temperature ductile carbon steel and extra lateral rail tolerances (12 mm expansion clearance) to prevent thermal binding.

All export ocean consignments destined for Australia, New Zealand, and North America are shipped either on custom heavy-duty reusable structural steel cradles or using heat-treated timber that strictly complies with ISPM-15 guidelines. Each wooden block carries clear HT dunnage stamps. We supply clean container declarations, commercial packing manifests, and Certificates of Origin (Form A / ChAFTA) to ensure rapid customs and biosecurity release without quarantine hold fees.

Our push back carriages are engineered with modular bolt-on wheel brackets rather than unserviceable welded axles. If a wheel bearing suffers mechanical damage from excessive impact, the cart can be unclipped from the aisle-face end-stop in under 15 minutes without dismantling the upright frame or neighboring rack bays. We provide standard maintenance spare parts kits (wheels, safety stops, and hardware) with every primary export shipment.
