Abstract
A car travels along a sheathed cable, especially a suspension cable of a bridge, with the cable sheathing being of sheet metal and forming a rabbet projecting radially outwardly and following a helical course in the lengthwise cable direction. The car has at least one drive member engaged in the rabbet grovoe limited on the side by the rabbet. The drive member can be moved by a drive device immovable relative to the car along the lengthwise axis of the cable, but movable on a track concentric with the lengthwise axis of the cable.
Claims18
A car for traveling along a sheathed cable having a metal sheathing forming a rib projecting radially outwardly and extending axially along the cable in a helical path, said car comprising:
- at least one drive member having coupling means for engaging the rib laterally and at least two relatively movable parts arranged one behind the other along the helical path of the rib, said parts trapping the cable therebetween and having biasing means for urging said parts against the cable;
- and
- drive means, coupled to said drive member, for moving said drive member along a track concentric with a longitudinal axis of the cable, said drive means being stationary in axial directions of the cable relative to the car.
A car for traveling along a sheathed cable having a metal sheathing forming a rib projecting radially outwardly and extending axially along the cable in a helical path, said car comprising:
- at least one drive member having coupling means for engaging the rib laterally;
- drive means, coupled to said drive member, for moving said drive member along a track concentric with a longitudinal axis of the cable, said drive means being stationary in axial directions of the cable relative to the car;
- a machine for applying the sheathing with the rib being axially spaced from said drive member and said drive means;
- and
- a bottom extending over an axial length corresponding to said machine, said drive member and said drive means.
A car for traveling along a sheathed cable having a metal sheathing forming a rib projecting radially outwardly and extending axially along the cable in a helical path, said car comprising:
- at least one drive member having coupling means for engaging the rib laterally;
- drive means, coupled to said drive member, for moving said drive member along a track concentric with a longitudinal axis of the cable, said drive means being stationary in axial directions of the cable relative to the car;
- and
- at least one bearing pulley bearing on the cable, said pulley having a bearing groove with transverse slots engaging the rib.
