Abstract: A safety tie-down roller (1) has a spring laden ratchet pawl (9) positioned at an opposite side of structural framework (11) from a ratchet gear (8) and its related working conditions. A handle (33, 34, 35) is provided to release the ratchet pawl (9) against pressure of a spring (20, 37, 40, 42) for unloading cars and for straightening out chain to prevent loosening hazards. A wrench socket (45, 46, 51) is provided in addition to bar wrench apertures (15) for fast ratchet wrench rotation or optionally for motorized wrench rotation of the tie-down ratchet gear (8). Accurate torque control is made possible by the wrench sockets with either a hand torque wrench or a motorized torque wrench. Adapter plates (47, 49) are provided in addition to convenient forms of special hand wrenches (57, 58, 60).

Abstract: An automobile tie down assembly for use on vehicle supporting track assemblies in vehicle carriers to secure the vehicle being carried on the track assemblies including a guide assembly to guide the flexible tie down member attached to the vehicle and a tie down mechanism for winding the flexible tie down member thereon to tie down the vehicle where the tie down mechanism includes a tie down winding shaft onto which the flexible tie down member is wound, an input drive member adapted to be engaged and rotated, and gearing means interconnecting the tie down winding shaft and the input drive member so that rotation of said input member rotates the tie down winding shaft, the gearing means constructed and arranged so that said gearing means is substantially irreversible whereby the input shaft can be rotated to drive the tie down winding shaft while rotation of the tie down winding shaft to drive the input shaft is substantially precluded.

Abstract: A car haul trailer for transporting vehicles which includes a trailer frame with a base frame and a pair of spaced apart upstanding side frames between which are mounted a plurality of fixed and movable track assemblies so that the track assemblies can be positioned in a plurality of positions to accommodate different loads of vehicles to be transported.
