Class Information
Number: 187
Name: Elevator, industrial lift truck, or stationary lift for vehicle >
Description: This class is the locus for apparatus (i.e., elevator) for shifting a discrete load, in its entirety, from an entry level to a vertically spaced exit level along a fixed path when the apparatus includes (1) a reciprocating, load-underlying, support surface (e.g., car), (2) rigid or semirigid means for contacting and limiting the travel of the load support surface to the fixed vertical path, and (3) either (a) drive means* (e.g., fluid motor, manually operated linkage) for transmitting to the load support surface the force necessary to shift the load between the levels or (b) motion resisting means (e.g., counterweight) for slowing the travel of the load supporting surface when moving from a higher load entry level to a lower load exit level.
