Rail (10, 30) for use at boom hinges (5) of a crane (1), extending longitudinally from one end (11) to an opposite end (12), comprising a rail head (13, 33) having a running surface (131) for a wheel of a railway vehicle, a rail foot (14, 18, 38) for fastening the rail, and a web (15) connecting the rail head to the rail foot and interposed between the rail head and the rail foot, wherein the rail head is continuous along the length of the rail. The rail comprises a resilient member (16, 36) extending across the web (15) from the one end (11) of the rail over a length shorter than the length of the rail in order to provide a resiliency of the rail head (13, 33) relative to the rail foot (18, 38) over a length of extension of the resilient member. |
