Abstract: A hollow profile (1, 15), in particular crane girder for a crane (14), wherein the hollow profile (1, 15) has a cavity (2) and an outer wall (3) bounding the cavity (2), and at least one fastening element (4) protruding from the outer wall (3) for the, preferably re-releasable, fastening of at least one add-on part (5) to the hollow profile (1, 15), wherein the outer wall (3) has at least one passage opening (6), which opens into the cavity (2), for the fastening element (4), and an intermediate space between that portion (36) of the outer wall (3) which bounds the passage opening (6) and the fastening element (4) which is guided through the passage opening (6) is sealed with a sealing compound (7).

Abstract: Camera dolly track has adjustable width and is foldable for transport or storage. A track section has first and second rails connected via first and second cross braces. The cross brace includes a first bar pivotally attached to the first rail, and a second bar pivotally attached to the second rail. The first bar is securable onto the second bar at multiple positions along the second bar, to change the length of the cross brace to allow a track width of the dolly track to be changed. The length of the cross brace may be changed via a straight slot in the first bar and at least one projection in the second bar extending into the slot, to allow the bars to slide in and out over each other.

Abstract: Temporary support structure that provisionally supports the railroad tracks (12) with traffic during the execution of works below the track, such as the jacking of a reinforced concrete box (13) for elimination of a level crossing.

Abstract: Supporting arrangement intended to be arranged in a shoring zone of railway lines (17), where at least first longitudinal metal beams (12) are arranged parallel to a line of the track on the outer side of each track line (17) so that they are braced by at least one second perpendicular metal beam (14) with a length less than that of the first longitudinal beams (12) and the joining of each longitudinal beam (12) to one end of the perpendicular beam (14) is performed by means of a mechanical fixing means (15).

Abstract: A support system for a rail section which bridges the gap between foundations which are relatively movable auxiliary rails running parallel to the rail across the sleepers which are supported by the foundation, and underpinning supports providing a stiff connection between rail and auxiliary rails. The underpinning supports move in response to relative movement of the foundation so that undesirable rail bending is avoided.

Abstract: An adjustable railway fastening for securing a bridge girder or cover plate of the girder to a cross-tie on a bridge which includes a resilient clip having a planar body portion with an elongated slotted opening therein for a bolt which is offset with respect to the resilient end engaging bridge girder. The resilient end in the form of a compression arch engages a girder flange to limit vertical movement and a tie-engaging end includes downwardly and outwardly extending ears for laterally restraining the cross-tie. A shoulder on the resilient end also engages a side of the girder flange to further limit lateral movement. In order to provide greater resilience, the arch includes two separate finger portions joined at the base with the body portion to form a U, each of the finger portions having a lip adapted to overlie the girder flange. A plate has an aperture for receiving a bolt and a projecting lug adjacent to the aperture to facilitate securing a bolt tensioning member, i.e., a nut.

Abstract: A railway fastening, especially adapted for securing a bridge girder or cover plate of the girder to a cross-tie on a bridge, or like supporting structure, is in the form of a resilient clip having a substantially planar body portion with an opening for a bolt which is offset with respect to the resilient end engaging bridge girder. The resilient end in the form of a compression arch engages a girder flange to limit vertical movement and a tie-engaging end includes downwardly and outwardly extending ears for laterally restraining the cross-tie. A shoulder on the resilient end also engages a side of the girder flange to further limit lateral movement. In order to provide greater resilience, the arch can be in the form of two separate finger portions joined at the base with the body portion to form a U, each of the finger portions having a lip adapted to overlie the girder flange. A projecting lug adjacent to the opening for the bolt is provided to facilitate securing a bolt tensioning member, i.e., a nut.
