VEHICLE-MOUNTED LOAD INDICATORS

LASTINDIKATORER FOR FORDON

This investigation was an attempt to obtain details of research in different countries on vehicle mounted weighing systems. Information was received on seven different "load indicators", five English and two American. Four of the English types sense in some way the difference in the vertical distance between the vehicle frame and the axles caused by the spring deflection. One English type senses by means of strain gauges the bending of the axles or in the case of bogie axles some other part of the wheel suspension. The two American types both weigh the applied load by means of special load pads. The systems working on the first principle are suitable only for vehicles with steel springs. The vertical distance between the vehicle frame and the axles depends on the springs and as they have some built in friction damping the accuracy especially at loading and unloading is not very high. The systems working on the other two principles are fully accurate at loading and unloading although the accuracy of the system utilizing the bending of the axles is affected if their tyres are standing on uneven ground. /TRRL/
