Coloured hoarses are becoming more and more common on British wheels. These covers, which are tapped with a rubber mallet, often include an arrow indicator so they can be aligned during installation to point at their neighbor. This arrangement provides drivers with a quick way to check wheel safety on a daily basis. Since the waterproof cover cannot slide around the nut, all unaligned arrows show loose wheel nuts. An alternative to wheel nut indicators is to add a torque band. It is a small strip of polymer that connects the nut to the surface to which it is attached and breaks when the nut comes off. [ref. needed] A new product promises not only to fulfill this role, but also to introduce another dimension of wheel safety: retorquing. Everyone knows that the vehicle`s wheel nuts must be installed at a predetermined rated torque to ensure secure attachment without damaging or deforming the wheel.
In 2018, Audi launched electronic wheel nuts for some of its most expensive models,[7] and by 2021, Audi had sold more than 1 million cars using this technology. [8] Wheel nuts come loose due to vibration and stress from heavy truck loads; This rarely happens with car wheels. If a truck driver has replaced a wheel, it is important that the wheel nuts are picked up after about 100 miles. To determine whether a wheel has been tightened or not, Retorque Systems` wheel nut indicators feature a patented two-tone swivel boom. First, they are mounted on newly modified wheels with the red side of the arrow facing outwards, indicating that the nut needs retorque. When the time comes, tire fitters use custom locking clamps to remove the covers, a torque wrench to tighten the bolts again, then manually swing the arrows on the covers so that the green side faces outwards, then retool them. This shows at a glance that the required retort has taken place. The driver had checked and signed his daily visit sheet. He was convinced that the wheel nuts were firm before he began his journey about eight hours before the wheel loss. Something similar can happen if the wheel was not clean when the nuts were applied or if the nuts are loosened when bending the wheel or expand and contract during heating and cooling.
Philip Brodey, Torque Specialist at Norbar Torque Tools, commented: “Wheel nut motion indicators are an excellent warning system to visually alert a driver, transport manager or mechanic that there is a potential problem with wheel nuts. Similarly, locking devices can help maintain initial torque. “Dear transport operators and managers: please, please, equip all your vehicles and trailers with wheel nut indicators; It will save lives. The first operator to test the system is Thanet Waste in Sandwich, Kent, which has a fleet of 30 eight-wheeled vehicles serviced by two garages. He continued: “Wheel nut movement indicators should not be applied until this best practice has been applied. The same applies to locking devices, which should not, however, replace the regular checks of wheel nuts required by law. Brodey also says that if an impact wrench is used to nut quickly, a low-capacity wrench should be used that never exceeds the final torque. “We regularly encounter situations in the truck and car shops where the wheel nuts are covered with an impact wrench before the torque wrench is applied for the final attraction. Wheel nuts can also come off if a wheel has been painted and the paint is not of good quality. The effect of the mother on the color tears the color. The paint washes behind the nut so that the nut rests loosely on the edge.
The vibrations gradually loosen the nut. When enough nuts come off, the wheel shears the rest and eventually jumps on the road. I invite you to buy these wheel nut indicators. You can save so much grief for everyone. Give instructions to your drivers so that if they leave a vehicle unattended, they walk around and check that the pointers are present. It`s simple. The ordeal I went through affected me and my family. It costs just £1.29 for each nut. For more information about this or other legal issues, call us on 01302 775 522 It is the responsibility of operators to ensure that the system effectively prevents the risk of wheel loss. Such a system should include at least the following: Installing Wheel Sentry® in your fleet shows that you take loose wheel nuts and wheel detachments seriously. A loose wheel nut indicator is a measuring tool that warns of loose wheel nuts, which are the most common cause of wheel fall on vehicles.
These steps can be complemented by regular (e.g. weekly) checks of bikes in the yard and cyclists who check the wheels every time they stop.
