Few events related to the operation of a motorcoach will embarrass a company easier or destroy its reputation for quality faster than having a wheelchair lift that doesn't function properly when it's needed.
Using a wheelchair lift during a move is an event. Everyone on the coach is aware of it, and most are watching. Passersby often stop to gawk.
So, when a wheelchair lift is balky, binding or busted it reflects almost as poorly on the company as the entire bus turning brutish on a lonely stretch of interstate.
Wheelchair lifts are required by law to be cycled or operated daily as part of the regular pre-trip routine.
However, it takes additional periodic maintenance to assure proper operation and longevity of lifts. The following checklist, prepared by the Fleet Support unit of Motor Coach Industries, includes steps operators should take at least at every oil change interval or once a month, depending on your lift model. (Consult your owner's manual.)
· Clean lift assembly thoroughly prior to inspection.
· Verify pump oil level and correct as necessary.
· Check lift operation while unloaded; verify for unusual noises, signs of binding, and bent or damaged parts.
· Inspect the lift frame and lifts for proper mounting; ensure that all fasteners are present and properly torqued. Also be sure to inspect lift frame and lift for cracks, broken welds, etc.
· Check all electrical connections and harnesses for routing.
· Verify that switches are smooth, that the lights function properly, and that the plug end is undamaged.
· Repair fraying and corroded components, including the hand control and its components. Make any needed repairs as soon as possible.
Following the lift manufacturer's recommendations with regard to type and quantity of lubricant to use, lubricate the lift.
After all repairs are complete, test the lift while fully loaded (use a person or a weight equal to person, such as sandbags) to check for proper lift operation. Always listen for unusual noises. Verify that the lift reaches proper heights. Correct as required and return the unit into service.
Consult the wheelchair lift owner's manual for proper repair and adjustment procedures. These manuals are usually available via the Internet from the lift manufacturer.
