Trucking of forest products is a very important segment of the harvesting process and it is monitored

relatively closely by external sources. Load weight is the focal point of the attention received

by log hauling. The optimization of load weights is therefore very important to a logging operation’s

success and this can be achieved only through adequate gross vehicle weight control.

Methods of load weight control are reviewed and possible applications discussed in this report.

Studies were conducted to evaluate the adequacy of load weight control achieved utilizing two quite

different methods. A reporting technique which provided loader operators with information about

trends in the delivery weights of trucks which they loaded was used to heighten their awareness of

problem areas in load weight distributions. This study was conducted at two southern paper mills

with substantially different truck weight regulation environments. Two separate case studies were

conducted on Virginia loggers utilizing on-board electronic truck scales.

Results of the loading study indicated that the passive treatment had affected the behavior of some

of the producers studied. The behavioral changes observed generally improved the economic optimization

of load delivery weights. The on-board scale studies indicated that the scale systems did

perform well in the applications observed. However, the economic benefits associated with use of

the scales were negligible for the two producers studied due to a reduction in delivery weights after

installation of the scales.
