Rack systems’ appearance is deceptively simple. Uprights and beams form a framework that holds pallets with loads of product. To the casual observer, these systems don’t look overly complex. So if a rack component is damaged, it should just be a matter of swapping in a new piece that looks the same and securing it, right?
In fact, nothing could be further from the truth. It’s true that most pallet rack designs support adjustability and assembly into multiple configurations. However, the precise determination of a rack’s design and construction results from a number of carefully conducted engineering calculations. An “easy” patch job may render an existing system unsafe. Or, it could create additional risk of collapse in a reconfigured or relocated system.
Racks Engineered for Single Application
Indeed, racking manufacturers create the vast majority of systems specifically for a single storage configuration and capacity. As explained in RMI’s ANSI MH16.1: Design, Testing and Utilization of Industrial Steel Storage Racks, if a pallet rack system can support more than one shelf configuration or profile, the Load Application and Rack Configuration (LARC) drawings should include all possible elevation configurations.
For systems with the original design documentation that have not been modified or reconfigured, damaged components can normally be replaced with identical new components from the same manufacturer.
The same does not hold true for undocumented or reconfigured systems. For that reason, owners and facility managers should not attempt to undertake a rack repair without first engaging the services of a qualified, professional engineer.
The Role of a Rack Engineer in Damage Repair
The engineer will supervise and direct the assessment of the system’s condition. They will also design and oversee the ultimate repair or replacement.
To begin, the engineer will first examine the existing structure and compare it to its original sealed and stamped engineering drawings as well as to current applicable building codes and standards. This process verifies that the structure is still in its original location and configuration.
It also determines if a system installed several years ago still meets current standards, which continuously evolve and improve over time. Without first conducting this critical evaluation, simply repairing a damaged component may leave the rest of the system in an unsafe condition and can lead to failure.
