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).Other References
