OFF-HIGHWAY BRAKE PERFORMANCE DIFFICULT TO PREDICT

New and more stringent codes are evolving for the braking performance of off-highway open pit mining trucks. A series of actual truck performance tests was conducted to learn whether stopping performance was predictable, to determine fade characteristics of available linings, and to compare actual with theoretical brake performance under various conditions. Tests were carried out with a 152 tonne (170 ton) WABCO Haulpak truck equipped with Rockwell Stopmaster shoe brakes. A series of stops at maximum brake operating pressures were run on level, 6%, and 10% grades, empty, half loaded, and fully loaded. Two different lining mixes were studied.
