DEFINITION

Classification: 414/556

Carrier comprises movable component of load-receiving portion:

(under subclass 546) Apparatus wherein the carrier comprises an element or segment of the load-receiving portion of the vehicle, which element or segment is movable relative to the remainder of the portion.

SEE OR SEARCH THIS CLASS, SUBCLASS:

469, for a self-loading or unloading vehicle having a load receiving portion, or a significant section of the portion, which is pivotable relative to the horizontal. In the instance where only a section of the portion is pivotable, and the movement of that section places a load on, or removes a load from, the vehicle, there may exist considerable similarity with some of the art of this subclass (556), the difference amounting primarily to what proportion of the load receiving portion is represented by the movable significant section of that subclass or by the movable component of this subclass.

546, for related structure, but wherein the carrier is in the nature of an attachment to the vehicle, rather than a component of the load-receiving portion.
