Load and Safety Testing for Warehouse Racks

In the process of inventory management, ensuring the safety and efficiency of goods is always a top priority. And to achieve this, warehouse rack inspection is an essential step. Let’s explore in this article the importance of warehouse rack inspection, the implementation process, and why it is necessary to ensure that your goods storage system always meets safety and efficiency standards.

Why inspect warehouse racks?

Warehouse rack inspection is an important task as stipulated in labor laws, demonstrating the importance of this service. It is not only a mandatory task according to legal regulations, but also shows our spirit and awareness in ensuring the safety of workers.

To ensure that the racks operate smoothly and avoid unexpected incidents, we must remember that this directly impacts the quality of goods and, more importantly, the safety of employees. Inspection before putting the racks into use is always a top priority.

Some reasons for this are:

– Structural deformation: Shelving often bears heavy loads for extended periods, which can lead to structural deformation.

– Collision risk: During transportation and use, unexpected collisions can occur between shelving and vehicles such as forklifts. These collisions can cause dents, damage, or weaken the stable connections between joints, increasing the risk of system collapse.

– Significant investment: Businesses often invest a substantial amount of money in purchasing and installing shelving. They expect this asset to be preserved and operate efficiently for a long time.

For these reasons, regular inspection and maintenance of shelving become urgent and must be carried out frequently. This not only ensures safety but also helps protect assets and maintain the performance of the shelving system.

If the inspection process does not detect any defects or problems in the system, entrepreneurs or business owners can continue to use the system normally. However, if any problems or issues are identified, repair and remediation are necessary. Through this inspection process, business investors can detect problems in a timely manner and take necessary maintenance measures to avoid serious situations later on.

Standards for warehouse rack inspection

The standards established to assess the operational status of the system include the following regulations and reference standards, applied during warehouse rack inspection (inspection and testing of storage racks):

– TCVN 4244:2005: Applies to lifting equipment.

– TCVN 338-05: Applies to the inspection of steel frame structures.

– FEM 10.3.01 Adjustable Pallet Racking: Tolerances, Deformations and Clearances.

– European Design Code for Pallet Racking – M.H.R Godley, J. Michael Davies.

What to check when inspecting warehouse racking

To ensure that the racking system continues to operate efficiently, it is crucial to carefully check the following aspects:
– Check for warping: Carefully examine the horizontal and vertical beams of the racks for any deformation.
– Inspect the base plates: Verify that the rack base plates are securely fixed to the factory floor to ensure stability.
– Check protective uprights: Ensure that the protective uprights for the rack frames are still effective in dealing with any unexpected situations that could deform the racks. If necessary, replace them with new uprights to ensure the safety of the rack frames.
– Check for deflection: Racking systems often have Pallet Beams. Check if they are deflecting after being overloaded. If so, after removing the goods placed on the beams, ensure that they return to their original shape.
– Check the attachment of the beam to the upright frame: Ensure that the beam is still securely connected to the upright frame to ensure the safety and stability of the system.

Warehouse Rack Inspection Process

Warehouse rack inspection is typically performed after installation is complete. During this phase, businesses often hire independent inspection organizations to conduct safety checks before the storage system is officially put into operation. The inspection process requires high precision and reliability, and using independent inspection units ensures accuracy during deployment. To begin the safety inspection process, we must follow these steps:

Step 1: Check technical and installation documents for warehouse racks

– Documents to be cross-referenced and checked include: design drawings, installation diagrams, and calculations for actual installation.
– Review previously performed inspection procedures, especially in the manufacturing and testing process.

Step 2: Measurement and technical inspection

Observe the installation location of the storage racks and comply with safety guidelines for equipment use:

– Proceed with measurements and compare the equipment dimensions with the technical drawings.
– Inspect the entire bolt system and metal welds connecting the racks, as well as the material structure of the system, such as columns, braces, and beams. Do not overlook checking the factory floor where the racks are placed.
– Evaluate errors during installation, especially the inclination of the storage racks relative to the installation surface.

Step 3: Test the warehouse rack load

Testing is only performed after the requirements from the previous sections have been confirmed. The testing process includes:

– Load bearing test: Perform a 100% load test to check the rack’s ability to bear weight.
– Measure the deflection of the horizontal beam: Measure the deflection of the horizontal beams when they are subjected to their limit.
– Determine the deformation of the system: Measure the deformation of the system after load testing.
– Measure the tilt of the goods rack: Measure the tilt of the rack after loading.
– Evaluate the measured data: Based on the data collected from the tests, evaluate to ensure the safety and performance of the racking system.

Step 4: Evaluate the results of warehouse rack inspection

After completing the inspection and testing process, all relevant information will be recorded in the inspection report. If the system meets all evaluation standards, after a working period of about 5 to 7 days, the technical licensing process will be carried out. After completing all these steps, the racks will be put into operation.

Warehouse rack inspection period

Businesses need to carry out the rack inspection process according to regulations, while ensuring the safety of employees working with this system. Periodic inspections are carried out once a year.
