Adjustable anchorage for crane rails

摘要

An adjustable rail anchorage device including a rail clip (6) and a cam (3) rotatable around a fixed mounting bolt for laterally moving the rail clip into anchoring position on the rail. The cam (3) includes a passageway for the mounting bolt (8) and a circular boss portion with an outer circular wall having a gap defined at projected wall positions where the projected perimeter of the wall approximately coincides with the projected perimeter of the passageway to transfer lateral loads from the rail to the mounting bolt. A welded platform base with a raised haunch for locating the mounting bolt can be used to transfer lateral loads from the rail to the raised haunch.
