Practical Stress Behaviour of Complete Rail Fastening Systems

摘要

Conventional elevator design practice considers rail clips, brackets and rail anchors as separate units. Hilti conducted an analysis of how the complete rail fastening system acts under loading. This paper discusses the distribution of forces in the complete rail fastening system (rail clips, brackets and wall anchors) based on loads applied to the cabin rail. The results of practical tests disclose the failure mode of the various components of the rail fastening system and identify those that may cause a breakdown of the complete fastening system. Finally, the consequences an effective and cost efficient rail fastening system have for design are also discussed.
