Abstract
Disclosed is a collision avoidance method, controller, and system for a scissor lift. The scissor lift includes a passenger basket, a scissor extension mechanism, and a base with wheels. The collision avoidance system includes at least one of a basket proximity sensor sub-system that has proximity sensor elements disposed on the passenger basket. The collision avoidance system also includes a basket contact sensor sub-system that has impact sensor elements disposed within padded bumpers coupled to the passenger basket and a through-beam sensor sub-system mounted to the scissor extension mechanism. Still further, the collision avoidance system includes a wheel position transducer that is coupled to at least one of the wheels of the base.

21. A method for avoiding collisions between a scissor lift and surrounding objects, the scissor lift comprising a passenger basket, the method comprising:
-
providing padded bumpers coupled to the passenger basket, wherein impact sensor elements are embedded within the padded bumpers; detecting an impact condition of the passenger basket with respect to the surrounding objects by receiving impact information from the impact sensor elements; determining a collision status based on the impact condition; and activating a warning indicator when the collision status is within a predetermined warning threshold. - View Dependent Claims (22, 23)

24. A controller apparatus for a scissor lift, the scissor lift comprising a passenger basket, the controller apparatus comprising:
-
a sensing module comprising a basket contact sub-module that detects an impact condition of the passenger basket with the surrounding objects by receiving impact information from impact sensor elements embedded within padded bumpers coupled to the passenger basket; a collision module that determines a collision status based on the impact condition; and a warning module that activates a warning indicator when the collision status is within a predetermined warning threshold. - View Dependent Claims (25, 26, 27, 28, 29)
