Abstract
Transportation equipment having at least one deck for supporting and transporting four-wheel vehicles such as automobiles and trucks; at least one track secured to the deck; the track having a pair of substantially upwardly extending spaced apart surfaces; chock blocks for a vehicle transported on the deck to secure the vehicle against longitudinal movement; each chock block having a horizontal first member which nests with the track and is quickly removable from such nesting arrangement by upward displacement; each chock block having a second member substantially horizontally positioned and permanently laterally joined to the first member; the second member having a sufficient length to extend along, and terminate beyond, the tread face of a tire of a vehicle located along side the track; and the chock block having a lock for removably securing the first member to the track, when in nesting position therewith, to prevent the chock block from horizontal movement along the track and upward movement from the track.
