3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
automotive lift
device used to support a part of the chassis or body of an automobile to lift or lower the automobile
3.2
rated lifting load
maximum allowable mass that an automotive lift can lift or lower within the effective working stroke range
3.3
maximum lifting height
maximum vertical movement distance of the lowest contact support surface of the automotive lift and the automobile relative to the ground
3.4
