CLAIMED TO have advantages over conventional fixed weighbridges, Highwayman vehicle-axle weighing machines comprise a bonded sandwich of metal and elastomeric materials within which is a fluid-filled cavity connected to a read-out in the handle.
The load is applied to the cell through fixed points on the top and bottom plates and is measured by the displacement of the fluid in the read-out tube.
Being 527mm (207in) wide, the unit will accept all singleand double-wheel arrangements weighing up to six tonnes per wheel.
Drivers can weigh a vehicle with one Highwayman unit and one dummy in less than ten minutes to within two per cent accuracy.
Recent design modifications include an improved underside to allow easier mounting for heavy lorries, a new control valve which eliminates any possibility of air entering the system, and a change in the colour of the fluid to blue against a white background to give a clearer read-out.
The machines weigh 26kg (571b) and cost Oa
