ABSTRACT:
An adjustable rail anchorage arrangement comprises: a support surface (24) for supporting a rail (26). A platform base (4) is fast with this support surface and a boss (9) is upstanding from the platform base. A passageway in the boss captively receives a threaded bolt and nut assembly (1/2/23) having a shaft (2). A rail clip (15) has a hole (17) that encompasses the boss and the shaft and there is a cam (18) having a hole (20) whereby the cam is fitted over the boss and the shaft. A cam surface of the cam engages the rail clip whereby rotation of the cam causes lateral movement of the rail clip, whereafter the cam can be clamped in position by the bolt and nut assembly.
