Failsafe support for height adjustable passenger loading bridges |
摘要 |
A failsafe support for use with a height adjustable passenger loading bridge. A main support member supports the weight of a passenger loading bridge passageway under normal operating conditions. The failsafe support includes a self-arresting mechanism for varying a length of a height-adjusting portion of the failsafe support in order to raise and lower a support portion of the failsafe support. The support portion is positionable adjacent to and spaced apart from a lower surface of the passenger loading bridge passageway, for supporting the weight of the passageway in the event of a failure of the main support member. The self-arresting mechanism prevents the passageway of the passenger loading bridge from descending to a level below the support portion.
