TO: AC Transit Board of Directors
FROM: Michael A. Hursh, General Manager
SUBJECT: Wheel Chair Ramp/Lift Maintenance
BRIEFING ITEM
RECOMMENDED ACTION(S):
Title
Consider receiving a report on wheel chair ramp/lift maintenance, operator pre‐checks and how lift issues are managed including an analysis of the September 2019 road calls. [Requested by Director Shaw - 10/9/19]
Body
STRATEGIC IMPORTANCE:
Goal - Safe and Secure Operations
Initiative - Service Quality
This briefing item provides road call performance and Operator pre-check data that will be used to enhance the District’s ability to deliver safe, reliable, and sustainable service.
BUDGETARY/FISCAL IMPACT:
There is no specific fiscal impact for this briefing item.
BACKGROUND/RATIONALE:
As requested by the Board, staff is presenting this briefing item on the wheelchair deployment analysis used to monitor pre-checks and improve road call failures. The District experienced seven (7) wheelchair ramp/lift related road calls between report date August 31, 2019 to September 30, 2019. Analysis found that four (4) of the road calls resulted in items lodged in the ramp drawer preventing operation, two (2) road calls had defective kneeler switches, and one (1) road call required a mechanical adjustment to the proxy sensor.
The following table details the road call incidents that includes time stamps on the division departure, road call, and wheelchair ramp/lift deployments to indicate if a pre-trip deployment was made. Based on the data, one (1) failure may have been preventable through Operator pre‐check depending on when the item was dropped and lodged in the ramp.

The table above is an example of a new Lift Analysis Report being developed that will provide pertinent information to identify root causes of road calls and possible preventable measures to enhance performance and reliability of the equipment. Division staff will use this report to validate if a proper pre-trip inspection was performed by the Operator. Division staff will also complete regular “gate” checks along with Road Supervision to verify that each Operator has deployed the ramp/lift during their normal bus pre-trip inspection.
