Heavy Goods Vehicle Inspection: Road Wheels and Hubs Mobile App
The primary purpose of the Heavy Goods Vehicle Inspection: Road Wheels and Hubs mobile app is to support staff in conducting the annual testing of vehicles.
How does it work?
The app is useful to those responsible for the maintenance of large commercial vehicles so that they remain well informed on the current minimum legal standards for roadworthiness. It must be emphasised that these are minimum acceptable standards, which do not necessarily allow for further deterioration when the vehicle is in service. This inspection applies to all road wheels and hubs apart from spare wheels. Where possible wheel nuts will be lightly tapped with a hammer to check for looseness, but any other evidence such as rust marks or elongation of bolt/stud holes must also be taken into account. A nut or stud is considered to be “loose” if it is not obviously carrying out its function of clamping the wheel to the hub. With some vehicles it is not possible to see the road wheels completely from ground level, especially with twin wheels and where the body hides part of the wheels. In such cases the vehicle must be moved to expose hidden parts of the wheels, or examined from underneath.
