註釋A tridem is defined as a group of three axles that are equally spaced and equally share the load. This report describes a project to monitor the operational performance and maintenance requirements of a new tridem tractor designed with stability-enhancing features and used for transportation of logs in the Slave Lake region of Alberta. Tests of the tractor included both normal operation in a single-articulated combination (with a pole trailer) over forest roads in both wet and dry conditions, as well as a series of controlled steering response and traction tests to compare the performance of two- and three-drive axle log haul tractors in combination with a tandem axle pole trailer under three different load conditions. Additional tests compared the tractive ability of a tridem drive axle tractor with a conventional tandem drive unit. Recommendations are made regarding the suitability of tridem drive tractors for log hauling applications in Alberta for combinations similar to those evaluated during this project.
