UK garages typically choose between CCD (Charged-Coupled Device) and 3D alignment technology. CCD machines use electronic sensors on each wheel that communicate with one another via Bluetooth, Zigbee, or infrared. They are highly versatile because they do not require a fixed "tower" at the front of the lift, making them ideal for smaller workshops with limited space or those using 2-post lifts. 3D Wheel Aligners are a totally different concept, using high-resolution cameras mounted on a tower to recognise passive targets attached to the wheels. They are generally faster for high-volume tyre shops and have fewer electronic components on the wheels themselves, reducing the risk of drop damage. However, they usually require a dedicated, level alignment bay and more space.
These two types of system make up the mainstay of the machines sold in the UK, but at either end of the spectrum you also have the older style laser units. Laser aligners were huge back in the day, and many a technician today will was lyrical about their ‘old Supertracker’ or Balcolign. However, today they are largely a bit dated, and most notably don’t tend to be able to provide the convenience of a database or printout. Contrasting this, there is a growing interest in Touchless or ‘drive-through’ alignment systems. As the description suggests, they are far more automatic, and they have their place, albeit probably not in the realms of the everyday workshop!
Ultimately, wheel alignment, the correct product and the best practise in use, is a very subjective thing. If you have ever sat in a room with alignment ‘boffins’ arguing about the benefits or drawbacks or roll-back or 3 or 4 point clamps, you would know what we mean. At Giuliano UK, we really don’t over complicate it. You want a reliable product, from a company you can rely on, and we can provide exactly that.
