Failure was a key interest. Would it break? Would it shatter? No.
All of the components’ integrity remained intact. The push button lock eventually failed by extreme compression in minor buckling. Impressively – this took 600-1000 lbs of force. Keep in mind that the BACK UP Tools are designed to transfer 50% of body weight, and this would hold a human up to double that load.
Conservatively, we’ve easily rated the BACK UP Tools for up to 375 lbs.
We know that the tools will not just be used in a 90-degree vertical position but must flex to different angles with dynamic use. The tools were run through this modeling. The results showed that the Arms’ integrity would remain intact, allowing up to 9 inches of bend before failure. This is a considerable range well outside normal use and allows the user confidence and awareness of dynamic pressure.
The engineers who tested the tools were blown away by their performance and the integrity of the tools. We are enthralled by the performance – but not surprised. We know every detail of quality required for industrial use and inclusion to accommodate different bodies and different applications at work.
Proud of our tools built for trade workers – by trade workers.
