Abstract
Since 2000, all tractors and trailers manufactured in Canada are required to have anti-lock braking system (ABS). It is difficult to keep these systems operational in off-highway applications such as log-hauling. The most frequent issues with these systems involve wheel-speed sensors and wiring. This guide provides a brief overview of these issues and recommends best practices for maintaining these systems.

Abstract
In order to provide bridge designers with better information, International Forest Products Limited (Interfor) asked the Forest Engineering Resarach Institute of Canada (FERIC) to evaluate the bending strength and stiffness of log stringers used for constructing bridges on forest roads in coastal British Columbia. Given the lack of definitive standards for testing this material, FERIC developed a field-based test procedure and designed a test facility for destructive testing of full-size, whole-log stringers obtained from second-growth stands. Sixteen coastal Douglas-fir and twelve western hemlock logs were tested in 2003. This report describes the test procedure and methods of analysis, presents the log bending strength and stiffness results, and makes recommendations regarding future testing.

Abstract
This report describes the development and monitoring of two off-highway tridem pole trailers operating on Vancouver Island. The project was conducted from 1993 to 1997 by FERIC, and MacMillan Bloedel Limited. The report details the design and fabrication operational experience and productivity, brake maintenance costs, and braking performance of the tridem pole trailer. In addition, a cost-benefit analysis for converting conventional tandem pole trailers to tridem pole trailers was conducted.

Abstract
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.

Abstract
In the fall of 2001, several cooperating organizations conducted full-scale stability and dynamic tests for a wide range of heavy vehicle configurations in British Columbia. The Forest Engineering Research Institute of Canada (FERIC) facilitated the testing of six log hauling configurations. This report summarizes the rollover stability and dynamic performance of these configurations and compares their performance with two reference configurations (ship and tanker Super B-trains).

Abstract
An increase in steep-slope harvesting brings the need for a greater understanding of how machines can operate safely and efficiently on steep terrain. This study aimed to investigate the sensitivity of different operating positions for non-tilting and tilting machines, and to propose a methodology for determining safe operating parameters.

Abstract
Lower delivered wood costs can be achieved by reducing the tare weight of logging trucks and thereby maximizing the payload. The Forest Engineering Research Institute of Canada (FERIC) evaluated a low tare weight, double pole trailer design operating in Alberta under a special permit. FERIC conducted several individual studies to assess the dynamic performance and facilitate regulatory approval of the new design. This report summarizes these studies and presents the results of the dynamic performance evaluation.

Abstract
This report described a field trial of an antilock brake system (ABS) installed on an off-highway log tractor operating on Vancouver Island, British Columbia. The trial was conducted between 1992 and 1994 by FERIC, and MacMillan Bloedel Limited. The objectives of the study were to increase overall braking capacity by utilizing the steering axle brakes, while addressing steering axle wheel lockup concerns, and to determine the overall effectiveness of ABS in an off-highway application.
