Installing or reinstalling second-hand racks can be an excellent solution for optimising storage space at lower cost. However, even if they are second-hand, it is essential that the racks are correctly fixed to ensure their stability and the safety of personnel.
Inadequate fixing can lead to tipping, deformation or serious accidents.
In this article, you’ll find out how to fix second-hand racks correctly, what steps to follow and what precautions to take before, during and after installation.
1. Why is fixing a used rack essential?
Fixing a rack – whether new or used – is compulsory in the vast majority of situations. This fixing allows :
- to guarantee rack stability,
- prevent tipping over when loading or colliding with trolleys,
- to support the rated load,
- ensure compliance with warehouse safety standards.
An unsecured rack may look stable when empty, but becomes dangerous when loaded.
2. Before mounting the rack: essential checks
Before any fixing, it is essential to check the condition and characteristics of the used rack:
1. Check the condition of the uprights and cross-members
- No visible deformation
- No significant corrosion
- No structural shocks
- No distorted assemblies
2. Ensure that the components are compatible
Second-hand racks are sometimes made up of mixed elements. Incompatibility can reduce structural strength.
3. Check the ground
- The floor must be flat, clean and sufficiently resistant (concrete recommended).
- An irregular or fragile tile can compromise the fixing.
4. Determining the load plan
Before fixing, you need to know the rack’s maximum load in order to adapt the number and type of anchors.
3. What types of fastener should be used?
Fixing is mainly by mechanical anchors or chemical anchors, depending on the nature of the soil.
1. Mechanical anchors (the most common)
- Steel anchors
- Quick installation
- Very good resistance
- Recommended for most pallet racks
2. Chemical anchors
- Used when the concrete is friable or old
- Provide very strong hold
- Requires more technical implementation
3. Mounting plates
Each upright must be fitted with a suitable plate, designed to contain the anchor and distribute the forces on the ground.
4. Steps for fixing a second-hand rack
1. Position the uprights
- Position the uprights according to your layout plan.
- Check for squareness and alignment.
2. Fit the first sleepers
- Install the bottom crosspieces to stiffen the structure.
- Check that they are fully locked (pins, hooks, etc.).
3. Drill the anchor holes
- Use a professional percussion drill.
- Observe the depth specified by the anchor manufacturer.
4. Install the anchors
- Insert the dowel or rod depending on the type chosen.
- Tighten to the recommended torque.
5. Fix each amount
All uprights must be fixed, with at least 1 or 2 anchors per plate depending on the load.
6. Raise the remaining levels
- Gradually add the crosspieces and accessories.
- Check that they are horizontal.
7. Finalise with a rigorous check
- Check that the rack is plumb
- Check every anchor
- Confirm that the crossbars are locked
- Make sure the structure meets safety standards
5. Mistakes to avoid
- Do not fix all the uprights
- Fixing to fragile or unsuitable flooring
- Use anchors that are too short or of poor quality
- Mixing incompatible parts
- Climbing without a load plan
- Reusing previously installed anchors (prohibited)
- Do not check the condition of the rack before installation
These errors can reduce the rack’s capacity or even cause it to collapse.
6. Good practice after installation
- Install clearly visible load signage
- Check anchors regularly
- Checking for impact and deformation
- Train staff in correct handling
- Annual inspection of the structure
Conclusion
Securing a used rack correctly is an essential step in ensuring the safety of your storage space. This involves:
- check the condition of the equipment,
- use suitable anchors,
- methodical installation,
- and apply rigorous checks after assembly.
With proper and secure installation, a second-hand rack can offer excellent longevity and performance comparable to that of a new rack.
