A TRANSDUCER-BASED system for monitoring vehicle axle weights has been announced by Interlube Systems Ltd, Estovor Road, Plymouth, Devon (tel 0752 775781).
This device—the Axlemaster—gives an in-cab warning when the axles are close to fully loaded and are fully loaded/overloaded.
Two transducers are fitted per axle and these are connected via a chassis-mounted amplifier to an in-cab audio/visual display. Axle deflection is converted into an electrical signal; the transducers are calibrated during installations to suit plated axle weight. The audio visual display unit shows a vehicle profile with bulbs fitted at the axle positions.
At 90 per cent of full load the lamps flash green and an audible alarm sounds; and at full load the flashing green engaged. A mute button can be CUtS • COSt

light changes to flashing red with an audible warning still used to silence the alarm.
A constant green light indicates that the device is working and that the axle loads are below 90 per cent of the plated value.
The device is designed to give individual axle as opposed to gross vehicle weights. For vehicles having a gvw below the sum of the plated axle weights it may be possible for the device to register that both axles are within their plated maximum even though the gvw has been exceeded. A spokesman from Interlube was unable to make any comment.
Fitting is claimed to take as little as two hours.
