<p>The rail track consists of at least one main run (Vp) serving a number of storage lines (V1, V2) at right angles to it, all made with rails (4, 5) welded to metal cross-members (18, 18') anchored to the ground by feet (14, 14') fixed to roughly levelled concrete surfaces (12, 12'). The feet have pairs of projecting threaded rods (15, 15') with nuts and plates (16, 16') controlling the height of the cross-members and rails. The cross-members can be welded to the plates, and the space between the initial surfaces and the plates can be filled with concrete.</p> |
