Log haul vehicle configurations and conditions

Dimension and weight limits for various vehicles hauling logs.


Vehicles hauling logs and exceeding regulated dimensions and weights must operate under permits.

These permits include conditions that a vehicle must obey when the dimensions and weights exceed the regulated limits.

Log truck safety study

The Forest Engineering Research Institute of Canada (FERIC), performed vehicle dynamic research into common log truck configurations during the Western Log Truck Study between 1992 and 1998.

The main conclusion of this study was that the majority of existing logging trucks failed to meet the minimum criteria for safety performance, when hauling Alberta winter weights.

During 1999 and 2000, FERIC undertook a supplementary project to determine what improvements could be made to bring the safety performances up to the minimum standard.

Based on the results of this study, recommendations for the specifications of logging trucks have been developed, as contained in the Western Log Truck Study – Improvements to Dynamic Stability report.
