We install the Wheel-Check indicators during the vehicles regularly scheduled PM time. Then, unless the wheel has had work done on it outside, we do not put a torque wrench on the wheel again. This saves us 18 minutes per service. Two and a half services later the Wheel-Checks have paid for themselves. We also tried to destroy the product with Petrochemicals, by force, and by freezing it to 40º below zero fahrenheit, to no avail, the product integrity remained intact.

The drivers love them, on one of our operations a Nitrous Oxide B train has 160 wheel nuts. This unit travels a regularly scheduled run from Halifax, Nova Scotia to Victoria, British Columbia. The confidence the driver has that his wheels are now tight is very reassuring. He has stopped unnecessary stops to have the wheel nuts re-torqued. The drivers like how much quicker they can check their equipment. Also our drivers on slip seat or switch operations, if they notice a red Wheel-Torque indicator, they are then aware they must be more vigilant with this wheel assembly until they reach our terminal. The product also facilitates Official Road Inspections and shows our visual commitment to safety.

The maintenance staff enjoy the Wheel-Check indicators because now they have a visual re-torque check with the red ones. They don't have to rely on paper work flow. Also they appreciate the fact that management care so much about tires and wheels. It also sends a very positive signal to outside repair shops that we want and care about our wheel work being professionally done. Let us not forget the heat sensitivity of the product. While we have not had any bearing failures or brake overheats, as the head of transportation, I'm confident that it will be picked up quickly.

Thank you for choosing Air Liquide as the first company in North America to successfully test and use the Wheel-Check indicators.
