WINDS GIVE AWAY LORRY INSTABILITY

The safety engineering laboratory, which is part of the health and safety executive (hse), operates a number of full scale research facilities one of which is a large platform balance capable of force measurements in three dimensions. Designed for the investigation of wind force or other dynamic effects arising during crane operations, it was installed in an exposed location, 405 metres above sea level. Two research projects have recently been carried out, one on lorry stability, the other on crane wind forces. Enquiries following tipper lorry accidents show that over 900 occur each year in the UK. The force rig was utilized to carry out an investigation to establish the behaviour and stability of vehicles when loaded evenly and unevenly for various ground slope conditions. Measured vehicle centroid paths for different loading configurations and lateral tilt as the body tipping angle increases from zero (the road condition) to the maximum are given.
