Abstract:
1. A method for operating a lift comprising the steps of: providing a wheelchair platform connected to a vehicle and configured to move between a ground level position, a floor level position and a stowed position; lifting the platform; receiving a signal from a sensor associated with the lifting; controlling operation of the lifting in response to a level of the signal received by the sensor, wherein said controlling prevents movement of the platform when the signal level reaches a set value; and adjusting the set value from a first signal level to a second signal level based on additional platform position data about the lifting, wherein said set value is adjusted to the first signal level when moving the platform into the stowed position after moving the platform between the ground level position and the floor level position, and the set value is adjusted to the second signal level when moving the platform into the stowed position after moving the platform away from the stowed position.
