DEFINITION

Classification: 187/240

TRANSPORTABLE ELEVATOR:

(under the class definition) Subject matter constructed in a manner which makes it easily movable, as a unit, from one location where it functions as an elevator to another location where it again functions as an elevator.

(1) Note. The line between a portable elevator proper for Class 254, Implements or Apparatus for Applying Pushing or Pulling Force, is as follows: (a) Class 187 provides for transportable elevating apparatus which (a) lifts the entire load a significant distance between a loading and unloading position (e.g., greater than the height of a load being lifted), (b) is transported between use locations in an unloaded condition and (c) has a load supporting surface intended to be guided along or confined to (e.g., located within a shaft) a linear path, and (b) Class 254 provides for portable "jacking" apparatus which is movable between locations and either (a) elevates only one portion of the load, or (b) is manually transported as an assembled self supporting unit between use locations or (c) is carried and positioned under the load and is capable of lifting the load only a relatively short distance (e.g., less than the distance between the floor and ceiling of a room).
