DEFINITION

Classification: 414/481

Trailer-type vehicle and adjustable or removable tow-engaging structure associated therewith enabling lowering of forward end of vehicle for loading:

(under subclass 469) Apparatus wherein the vehicle is of a kind which is intended to be towed and has its wheels located in the vicinity of that end which is opposite to its usual direction of travel, and wherein there is provided structure (e.g.,., a separable connector of the "gooseneck" type, a reconfigurable forward extremity of the vehicle, etc.) for connecting the vehicle to a towing vehicle and pivotably lowering the forward end of the vehicle, relative to its rearward end, to facilitate the loading or unloading of the vehicle.

(1) Note. The towing vehicle ordinarily is of a "tractor" type and is provided with a "fifth wheel" for supporting the tow-engaging structure.

(2) Note. The vehicle of this subclass, often a trailer of "low-boy" kind, ordinarily is intended to have a load driven, or otherwise move, thereonto or therefrom by way of its forward end when the latter is in its lowered position.
