摘要:
A filler element (18) is located between each adjacent pair of outer strands (17) of a wire rope (10) and interlocks with the adjacent strands. The filler elements provide the rope with a substantially smooth outer surface, reducing vibration of the rope passing over a pulley. Filler elements are disclosed consisting of an elastomeric or polymeric material having an oriented molecular structure aligned along the filler element and also aligned in a generally radial direction with respect to the rope.

L'âme comprend un élément cannelé (1) en matériau polymère ou élastomère à cannelures hélicoïdales à espacement symétrique (2) ayant chacune la forme d'un arc elliptique en section transversale perpendiculaire à l'axe de l'âme. Une région centrale (3) peut contenir un élément de renforcement ou des conducteurs ou des fibres optiques.
摘要:
Equipment for making a wire strand is characterised by the following features: an elongate track (12); a clamp (14) at one, leading end of the track rotatable about an axis parallel to the track; an anchor frame (15) at the other trailing end of the track having rotatable tensioning spaced anchorages (16) for wires (17) extending parallel to the track; a trolley (18) movable along the track (12) and carrying adjacent the leading end a rotatable closing die (19) having an aperture (20) of cross-section corresponding to the cross-section of the strand (11), and adjacent the trailing end a grouper plate (21) having spaced wire guide apertures (22) corresponding to the anchorages (16) on the anchor frame (15), there also being on the trolley (18) intermediate the closing die (19) and the grouper plate (21) a lay plate (23) having wire guide apertures (24) with spacings intermediate the spacing of the guide apertures (22) in the grouper plate (21) and the closeness in the closing die (19); first drive means (25) for moving the trolley (18) along the track (12) from the leading end to the trailing end; second drive means (26) for rotating the clamp (14) at the leading end of the track (12) with a predetermined relationship to movement of the trolley (18); removable supports (27) for the wires (17) at intervals between the trolley (18) and the anchor frame (15); and removable supports (28) for the strand (11) at intervals between the rotatable clamp (14) and the trolley (18).
摘要:
A cable safety barrier has means for disengagement of the cable (102) from an anchor portion of the cable safety barrier when certain vehicle impact conditions are met. The means for disengaging the cable (102) may involve allowing a cable end fitting (204) to escape from an open ended slot (206), when the cable is deflected upwards, or causing the cable fitting to fail.

摘要:
A stranded rope (12) of large size is made by assembling a plurality of strands (10) and a core (11) side-by-side along a track (13); securing the leading ends in a clamp (14); securing the trailing ends in spaced anchorages (17, 18); applying tension to the strands (10) and core (11); guiding the strands (10) intermediate the clamp (14) and anchorages (17, 18) into the closed rope array round the core (11) by means of a closing die (20) on a trolley (19); moving the trolley (19) from the clamp (14) to the anchorages (17, 18); rotating the clamp (14) progressively as the trolley (19) moves progressively; rotating the trailing ends of the strands (10) and core (11) progressively in the same direction as the damp (14); securing all the strands (10) and the core (11) together adjacent the trailing ends; and releasing the tension from the strands and the core.
摘要:
Extruded polymeric rod (7) is elongated in the solid state by being drawn through a forming device (4) to produce a solid polymeric core (8) having an orientated structure which comprises elongated crystals orientated in the axial direction of the core (8). The core may also comprise crystals additionally orientated in respective radial directions (23). The single rod may be replaced by a bundle of rods.
