The increase in forest road grades on the coast of British Columbia has led to hauling safety concerns. To investigate this issue and to develop guidelines for hauling on these steep grades, the Forest Engineering Research Institute of Canada (FERIC) installed instrumentation on a coastal off-highway truck to measure braking energy requirements during typical steep grade descents. FERIC used the data to develop a computer model for predicting brake performance for steep grade descents and to develop descent guidelines for several operating conditions.
