curate wheel and axle gnment plays an important 1 in tyre service life. But rkshop methods of aligning as are either non-existent or iuently such hit and miss airs that little constructive iefit is derived from them. tting semi-trailer axles is nally completed using either piece of string or steel tape to asure the distance between kingpin and axle wheels. But matter how carefully this is le it cannot account for the .cts of uneven tyre wear or -set axles.
kccurate chassis aligning and aightening equipment has to available for some time so a surprising that we have had wait until now for a nufacturer to introduce equipnt which enables axles on any vehicle to be quickly and accurately aligned to the chassis. Bee-Line has produced the Tandem Aligner which uses a narrow beam of light focussed from the exact centre chassis position and projecting forward perpendicular to the axle on to a view extender fixed, in the case of a semi-trailer, to the kingpin. The axles are adjusted until the beam meets the view extender dead-centre mark.
The beam is generated from a unit mounted on a frame connected both between axle wheels and trailer/vehicle main frame. The unit is claimed to be easy to use, portable and able to give precise alignment on any vehicle within a few minutes.
The equipment is marketed by Arval Ltd, 190 Castelnau, London SVV13 9DJ.
