Abstract: A trolley travels in response to rotation of a winch along a main cable of a suspension bridge having a tower and support cables extending along and substantially parallel to the main cable. The trolley includes a support assembly engaged with the support cables, first and second enclosures suspended from the support assembly, each enclosure located at a laterally opposite side of the main cable, and a tugger cable engaged with the winch and connected to the support assembly for pulling the enclosures along the main cable toward the tower and/or allowing the enclosures to move along the main cable away from the tower.

Abstract: An extendable truck height measuring pole comprising a tubular body, one or more telescopic extension members slideably deployable from a stowed position in the telescopic body, a contact member on the distal end of the top most extension member and connected to the extension member by means of a pull-to-release joint. By operating the joint, the contact member may be deployed to a position at right angles with the longitudinal axis of the pole. Alternatively, the contact leg may be moved to a stowed position adjacent and parallel to the pole. Truck height is read from indicia on the extension member or members.

Abstract: A restraint assembly for securing an automotive vehicle to a flat-bed transport vehicle is adapted for use along with wheel chocks. The restraint assembly includes a synthetic, woven webbing strap having ends which are cut cold rather than by a heated blade; a standard, off-the-shelf ratchet mechanism with which the strap is engaged; a vehicle attachment hook attached to a second end of the strap; and a J-shaped hook for engaging a hole on the transport vehicle, the J-hook having a return bend that is approximately 180.degree. in arc length and an extended free end. The geometry of the J-hook serves to substantially prevent the ratchet mechanism from becoming disengaged from the transport vehicle due to bouncing of the restrained automotive vehicle on its suspension.

Abstract: A lightweight stowable carrier for a tire of an automotive vehicle such as a truck or trailer comprises a plurality of straps, preferably formed of woven webbing. In a first embodiment, one set of straps has ratchet buckles for securing the tire to the carrier in encircling relationship. Another set of load-bearing straps is provided with cam buckles for length adjustment and hooks for securement to the underbody of a vehicle. All of the straps cross one another and are stitched at a common centerpoint. In a second embodiment, three separate straps are attached to the tire at points spaced around its circumference. Hooks attached to first ends of the straps are passed around the tire and through coupling links attached to opposite ends to form choker loops around the tire. Two of the straps are of fixed length and the third strap is adjustable in length.
