A cable bending limiting arrangement is provided for an anchoring unit including an anchorage, a cable including a plurality of wires and/or strands extending in a tensioned manner from the anchorage, a compacting clamp unit adapted for compacting the wires and/or strands to a side-by-side arrangement and located at a predetermined distance from the anchorage, and a recess pipe surrounding the cable in at least a portion of the predetermined distance. The cable bending limiting arrangement includes a cable bending limiting device adapted for being located axially inside the recess pipe and radially between an outer surface of the cable and an inner surface of the recess pipe leaving an annular gap of a predetermined radial width if the longitudinal axis of the cable extends substantially parallel to the longitudinal axis of the anchorage.

The invention relates to a damping arrangement (100) for a cable (102) extending in a tensioned manner from an anchorage (108), said damping arrangement (100) comprising a rigid damping action transfer device (112) which is positively connected to the cable (102) at a predetermined distance (L1) from said anchorage (108), and at least one damping device (110) extending in a damping manner between said damping action transfer device (112) and a constructional element (106) rigidly connected to said anchorage (108), and connected to said damping action transfer device (112) at a further predetermined distance (L2) from said anchorage (108), said further predetermined distance (L2) being shorter than said predetermined distance (L1).

The proposed sheath is for a structural cable (10) having a path between an upper anchorage (16) and a lower anchorage (17). It comprises sheath segments (21) assembled along the path of the structural cable, at least one supporting rope (30) extending along the sheath segments and having an upper end connected to the construction work adjacent to the upper anchorage, and connectors (32) for connecting the sheath segments to the at least one supporting rope. The connectors (32) are configured to block relative upward movement of the supporting rope (30) with respect to the sheath segments (21) and to allow relative downward movement of the supporting rope with respect to the sheath segments.

A plurality of wire elements for use in an energy recovery device comprising Shape Memory Alloy or other Negative Thermal Expansion (NTE) material, wherein at least one wire element is fixed at one end and free to move at a second end, such that the wire elements are arranged adjacently and are in friction or interference contact with each other and are secured at the outer perimeter of wires utilising a securing means. In such arrangement, during the operation of the bundle arrangement in a heat engine system, the plate elements act to transmit the aggregated force generation of the wire grouping and thus usefully recover and transmit power.

A cable climbing robot includes a climbing front body and a detection body. The climbing front body includes a front body rack, duct propellers, a front body clasping units and a front body control modules, the duct propellers are mounted on the outer side of the front body rack; the front body clasping unit includes a front body clasping electric motor, a front body clasping transmission component and a front body clasping member; the front body clasping electric motor is fixedly mounted on the front body rack, and the front body clasping electric motor drives the front body clasping member via the front body clasping transmission component; the front body control module is mounted on the front body rack, and the front body control module is electrically connected to the duct propellers and the clasping electric motor.

A cable anchorage is described for anchoring a cable, for example a stay cable comprising multiple strands (50), against an axial tension force. Each strand (50) is individually sealed in an individual channel (6) of the anchorage against moisture ingress, and each strand (50) may be removed and replaced individually. A tight-fitting elastic annular seal (26) is fitted into a recess (27) in the channel. The annular seal (26) is inserted from the anchor block end (1) of the anchorage.
