DEFINITION

Classification: 187/222

INDUSTRIAL LIFT TRUCK OR REQUIRED COMPONENT THEREOF (E.G., FORKLIFT):

(under the class definition) Subject matter consisting of a mobile wheeled or tracked apparatus (e.g., forklift) or a specified component thereof (i.e., drive-means*, load support surface, guides for surface) not provided for in another class, which travels to, picks up, and shifts a discrete load, in its entirety, from one level to another vertically spaced level and then carries the load while still fully supported on the surface a short horizontal distance (e.g., the length of a warehouse) to a load discharge point.

(1) Note. The line between a mobile lift truck proper for this and the indented subclasses and one proper for Class 254, Implements or Apparatus for Applying Pushing or Pulling Force is as follows: (1) This subclass and its indents provide for a mobile wheeled or track guided truck which both

(a) selfloads, supports, and travels with a load between horizontally spaced locations and (b) is capable of vertically moving this load along a fixed path for a significant distance and unloading it at a different, vertically spaced level; and (2) Class 254 provides for a mobile lift truck which either (a) elevates only one portion of the load or (b) lifts the entire load only a relatively short distance (e.g., less than the height of the load) and then returns it to its original level when unloading.

(2) Note. Wheeled or tracked apparatus otherwise proper for this and the indented subclasses is excluded therefrom when the load support surface is mounted for movement in an additional direction (e.g., tilted) and is found in Class 414 subclasses 629, 631+, 641+, and 663+ even when the movement is not utilized to load or unload the surface (e.g., merely stabilizes the load).
