Rail joints
A rail 13 for supporting a trolley (14 fig. 1) of a gantry crane (10 fig. 1) has rail end sections 18, 19 on opposites sides of a joint 17 each end section 18, 19 comprising a projecting portion 21 and a rebated portion (22 fig. 2B) on opposite longitudinal sides of the rail 13. The end regions (20 fig. 2A) of the rail have a modified rail head profile that directs the wheels of the trolley (14 fig. 1) over ridges 23, 24 that rise gradually above the height (L2 fig. 5) of the head portion (27 fig. 5) of elongate rail member 32 remote from the end member 31 while approaching the joint 17. The ridges 23, 24 then carry the wheels into the joint 17 where the transition from one rail section 18, 19 to the next occurs over a reinforced region. The load-bearing apexes A of the ridges 23, 24 are disposed away from the side edges of the rail 13 and away from the ends of each projecting portion 21. The rail 13 increases the operational life of a crane rail 13 by reducing wear rate in high stress areas of the joint 17 and by adding additional wear material above the rail 13 at the joint 17.
