Recall Notification - Threshold Warning

Safety Standard Non-Compliance Recall Notification (#07E-095)

This notice is posted as a convenience to our customers who wish to check their Ricon lift serial number(s) against the master list of lifts requiring inspection and/or repair.Ricon Corp. has determined that a safety related non-compliance with S6.1 of the 403 (Threshold Warning System) exists in certain “DOT Public Use” and “DOT Private” platform wheelchair lifts manufactured between April 1, 2005 and October 9, 2007.


The non-compliance with S6.1 of the 403 is the result of the Threshold Warning System not detecting the presence of a wheelchair or mobility aid user in a certain spot within the defined threshold area. In the event this condition occurs during passenger operations the wheelchair or mobility aid user may move toward the vehicle lift door when the lift platform is below floor level. This situation could cause personal injury.
