Fleet Experience and Economic Analysis of the Prototype Controlled-Steering B-Dolly and Linked-Articulation Dolly. A Report to Saskatchewan Highways and Transportation

摘要

The purpose of the report is to provide an assessment of the performance of the CSB- and LA-dollies throughout the field service trial program. Primary objectives of overall assessment considered fleet experiences with respect to dynamic stability, offtracking, ease of operation, coupling, loading, backing, and life-cycle costs. Actual experience with the prototype dollies has been very satisfactory as regards functional and operational considerations. An economic analysis indicates that use of these dollies represents a cost penalty within the 'normal' regulatory environment, but that the additional weight allowance under new Saskatchewan regulation provides very strong economic motivation for using these safer dolly designs.
