1. What is Push-back Racking?
Push-back Racking is a warehouse shelf system designed with a smart pushing mechanism, allowing multiple pallets of goods to be placed in depth. When a pallet is placed, it pushes the previous pallet back by gravity.
2. What are the main advantages of the Push-Pull Rack system?
This system brings many benefits such as: optimizing storage space up to 75%, reducing operating time, increasing efficiency of goods management according to FIFO/LIFO principles, and ensuring safety during operation.
3. Why is Push-Pull Racking called a LIFO system?
LIFO (Last In First Out) is due to the operating mechanism of the rack – the pallet that is put in last will be taken out first. This is suitable for warehouses with fast turnover cycles.
4. What is the maximum depth of the Push-Pull Shelf?
Typically, the system can hold 2-6 pallets in depth, depending on design and usage needs. The most common depth is 4 pallets to ensure optimal operating efficiency.
5. What types of goods are Push-Pull Shelves suitable for?
This system is suitable for goods with the following characteristics: uniform size, medium weight, short storage time, and need to be managed by batch.
6. What is the standard load capacity of the Push Shelf?
Each pallet position can withstand loads from 800kg to 1500kg depending on the design. Total lane load can be up to 4000kg-6000kg with 4 pallet depth design.
7. How to operate Push Shelf safely?
Follow standard operating procedures: check loads, position pallets correctly, use appropriate forklifts, and regularly maintain the slide rail system.
8. Investment cost of Push-Pull Shelves compared to conventional shelves?
Initial cost is 30-40% higher than conventional selective racking, but provides higher space efficiency and better ROI in the long run.
9. What are the main components of the Push Shelf system?
Includes: main frame , sliding rails , rollers , stopper, and safety accessories.
10. How long does it take to install the Push Shelf?
Average installation time is 3-7 days depending on scale, with a professional and well-trained team.
11. How to properly maintain Push-Pull Shelves?
Periodic maintenance should be performed every 3-6 months, including: checking the roller system, cleaning the slide rails, checking the welds, tightening bolts, and ensuring the stoppers are working properly.
12. Can Push-Pull Racks be integrated with a WMS system?
Fully integrated with WMS (Warehouse Management System) via barcode, QR code or RFID to track exact location of goods.
13. How is Push-Pull Rack different from Drive-in Rack?
Push-back Racking allows access to goods from one side, while Drive-in requires the forklift to go inside the rack. Push-back is safer and more effective.
14. How to calculate ROI when investing in Push Shelves?
ROI calculation is based on: initial investment cost, space saving (75%), reduced operating costs (30-40%), increased work efficiency and average payback period of 2-3 years.
15. What are the safety standards for Push-Pull Racks?
Complies with EN 15512 , FEM 10.2.07 , is seismically resistant, has a safety stopper system, and is periodically inspected according to regulations.
16. Can the Push Shelves be installed outdoors?
Outdoor installation is not recommended due to weather effects on the track and roller system. Should be installed in a covered and humidity controlled warehouse.
17. How to optimize space with Push Shelves?
Modular design, maximize warehouse height, arrange goods by group, and optimize lane spacing for efficient forklift operation.
18. Common errors when operating Push Shelves?
Common errors include: incorrect pallet placement, overloading, collision causing rail warping, lack of regular maintenance leading to rail jamming.
19. Can the height of the Push Shelf be adjusted after installation?
Beam height can be adjusted within the allowable range (50-100mm) but requires a professional technical team to perform.
20. What is the minimum installation space required for Push-Pull Racks?
Minimum space required: 4m height, 2.8m width for a single lane, minimum depth of 3m for 2 pallet depth, plus 3.5-4m forklift operating clearance.
21. What are the warehouse floor requirements when installing Push Shelves?
Concrete foundation must have minimum strength M300 , FL (floor flatness) of ±3mm/3m, minimum load capacity of 3 tons/m2, be waterproofed and have no cracks.
22. Can Push Shelves be combined with other types of shelves?
Can be combined with Selective Racking , Drive-in Racking or Flow Racking in the same warehouse to optimize storage for different types of goods.
23. How to choose the right forklift for Push-Pull Rack?
Forklifts need to meet: suitable lifting height, fork width compatible with pallets, ability to rotate in narrow spaces, and suitable lifting capacity (usually 2-3 tons).
24. What is the average lifespan of a Push-Pull Shelf?
With proper maintenance, the system can operate efficiently for 15-20 years. Parts such as slide rails and rollers need to be replaced after 5-7 years of use.
25. Is training required for Push Rack operators?
Training is required in: standard operating procedures, safety, emergency handling, and basic maintenance. Average training time is 2-3 days.
26. What are the safety risks when using Push Shelves?
Major risks include: collisions when operating forklifts, overloading pallets, failure of the rail system, and collapse due to improper design or installation.
27. How to optimize the operating cost of Push-Pull Racks?
Implement regular maintenance schedules, properly train employees, optimize import and export processes, and use warehouse management software to minimize errors.
28. Are Push-Pull Shelves fireproof?
The system is made of steel with basic fire resistance, but needs to be coated with special fire-resistant paint meeting BS EN standards to increase the fire resistance time to 2-3 hours.
29. Can I install the Push-Pull Shelf myself?
Do not install it yourself because this is a complex system, requiring a professional technical team with specialized equipment and following standard installation procedures.
30. How to choose a reputable Push Shelf supplier?
Check factors: international quality certifications, project experience, after-sales service, warranty, and 24/7 technical support.
