Abstract
A device (10) for providing an indication of loads exerted on a vehicle frame (12) comprises a sensing unit (22) mounted to and between the frame (12) and the vehicle axle (14) and for detecting vertical displacement of the frame (12) relative to the axle (14) when loads are exerted on the frame (12). The sensing unit (22) comprises an arm (126) pivotally mounted to the frame (12), through a pair of telescoping tubes (32, 44), and an adjustment rod (124) movably mounted to and between the arm (126) and the axle (14). When a load is exerted on the frame (12), the same depresses relative to the axle (14) and the arm (124) rotates. Rotational movement of the arm (124) is measured by a clinometer (128) mounted thereto and which converts the angular measurement into a coherent digital or analogue readout displayed by a receiving unit (26).
