Wheelchair Lift Maintenance Policy

It is the intent of Columbia County Rider by way of this policy, to assure that our wheelchair lifts and ramps are maintained to the specifications prescribed by the device manufacturer. The maintenance of wheelchair loading apparatus will be performed by a combination of bus operators, mechanics and certified manufacturer technicians, depending on the level of service required. Services such as daily safety checks, monthly safety checks, and 10 cycle (daily) maintenance shall be performed by the bus operator and documented on the daily vehicle check sheet. All other maintenance and inspection shall be done by a qualified mechanic except those services where the manufacturer requires the service to be performed by a certified or authorized technician.


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 run sheet. There will also be a lift counter installed to use for verification in each vehicle. 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 three different maintenance schedules for Columbia County Rider wheelchair lifts/ramps, described below; Schedule A, Schedule B and Schedule C. These maintenance schedules will be listed on the fleet maintenance spreadsheets using the appropriate schedule for the type of lift in that particular vehicle. Bus operators will do the 10 cycle inspection each day during their morning vehicle check and anytime during a shift where the lift is cycled more than 10 times. The 10 cycle inspection is described in the Schedule B attachment. In addition to this:
Schedule A includes inspection and service at 750, 1500 and 4500 cycles with service and inspection at consecutive 750 cycles.

Schedule B includes inspection and service every 150 cycles, with additional services required at 1800 cycles. This schedule also requires service at 3600 cycles to be performed by a certified technician.



Schedule C is applicable only to manual wheelchair ramps and requires a monthly safety check which includes cleaning and light lubrication of pivot points and hinges. Services within this schedule may be performed by the bus operator.

Be certain undercoating is intact. Re-coat areas as required. Note: The rust inhibiting coating should provide years of trouble free service. However, severe condition (frequent use on unimproved or heavily salted road surfaces, etc) may cause premature corrosion. Any area where undercoating is bulging due to flaky rust should be cleaned using a wire brush, treated with primer and re-coated.

Hoses and fittings

Be certain that all fuel lines are intact and not damaged. Be certain that fuel fill hoses are free of cracking and damage.
