Wheelchair lifts shall be serviced based on duty cycles. A duty cycle is one full cycle from stowed position back to stowed position. The number of cycles a lift is operated in a given shift will be documented on the daily trip sheet. The supervisor will keep a running tally of the lift cycles for each vehicle, and send the vehicle in for the next designated service prior to reaching the maximum number of lift cycles allowed between services.
There are two different maintenance schedules for wheelchair lifts/ramps: Schedule A (Braun) and Schedule B (Ricon)
Braun: Schedule A: Includes inspection and service at 150, 750, 1,500 and 4,500 cycles with service and inspection at consecutive 750 cycles.
