Load sensing system for wheelchair lift arrangement

摘要

A load sensing system for a wheelchair lift arrangement includes an elongated member that is rotatable about a longitudinal axis between an unloaded position and a loaded position; a biasing member that biases the elongated member toward the unloaded position; at least one contact member connected to the elongated member and configured to contact a bridge plate; and a switch assembly operatively connected to the elongated member, the switch assembly being configured to be activated to prevent operation of the wheelchair lift arrangement when the elongated member is in the loaded position. A method of regulating movement of a lift platform of a wheelchair lift arrangement is also provided.
