ABSTRACT:
A fixture for elevated utility lines, deployable from a hoverable vehicle having a load attachment point, each fixture having a body with a slot formed therein for receiving the line; a trap having one or a pair of movable arms for holding the line within the slot; a cocking mechanism for holding the trap in an open condition; and a trigger mechanism activated by contact with the line for releasing the cocking mechanism, and a trap releaser including a supportive hook receiver for releasing the trap during removal of the body from the line. A system for deploying fixtures also includes a base, an attachment for releasably suspending the base from the load attachment point and having a stabilizer bar supportively connected relative to the attachment point and resiliently oriented relative to the vehicle, a yoke releasably supported relative to the load attachment point, the base being suspended from the yoke. A plurality of the fixtures can be stored on the base for deployment therefrom, at least one releasable fixture hook being supported on the base for engaging one of the hook receiving members. The fixtures are sequentially affixable at selected locations along the line, at least one of the fixtures being retrievable from the line by engagement of the hook receiver by the marker hook. The fixture can be configured as a safety marker, as well as a spacer for groups of conductors of the line.
