If separate accessories are furnished for use with a lift conforming to ANSI/ALI ALCTV (current edition), the separate accessory shall conform to the relevant national standards and shall be certified as such.  Placement of unrecognized accessories into a certified lift configuration invalidates the lift’s certification as long as the certified lift configuration remains altered.

The ALI Lift Certification Program requires each participant to submit all accessories for evaluation. Approved accessories are required to be listed for use by model number on ALI’s Directory of Certified Products. Accessories not found on the Directory are not approved for use.

Perhaps the most common example of a configuration altering accessory would be a wheels-free-device (rolling jacks) or high reach fixed stands.  Wheels-free-devices must be certified as an accessory to the lift model. For the safety of the technician and others in the immediate area, high reach fixed stands, when used in support of a certified automotive lift, must be certified in accordance with ANSI/ASME PALD or ANSI/ASME PASE, the safety standard covering portable automotive service equipment (ASME PASE has replaced ASME PALD).
