DEFINITION

Classification: 414/639

Tilting carrier:

(under subclass 592) Elevating devices wherein the load carrier as a whole has a tilting motion in a vertical direction (i.e., about a horizontal axis) at some point in its path of travel, usually for the purpose of loading or unloading.

(1) Note. The inclusion of a load by name only, e.g.,., car, container, or the like, in the absence of any structure adapting the carrier to such load, does not exclude the device from this and indented subclasses.
