Patent ID: 7950095

Claim:
A method for manufacturing a gangway, wherein the gangway comprises a plurality of tread supports and an underbody, said method comprising the steps of: providing a first tread support of the plurality of tread supports from a first continuous piece of metal such that the first continuous piece of metal defines a left flange area and a right flange area, connected to a tread area, wherein the left flange area and the right flange area are opposite one another with respect to the tread area, the left flange area and the tread area define a first fold line, and the right flange area and the tread area define a second fold line; folding the left flange area with respect to the tread area at the first fold line; folding the right flange area with respect to the tread area at the second fold line; providing the underbody from a second continuous piece of metal, wherein the second continuous piece of metal defines a first side area opposite a second side area with respect to a middle area located between the first and second side areas, the first side area and middle area define a first side fold line, and the second side area and middle area define a second side fold line; folding the first side area with respect to the middle area at the first side fold line so that the first side area becomes a left support of the underbody; folding the second side area with respect to the middle area at the second side fold line so that the second side area becomes a right support of the underbody; and connecting one side of the first tread support to the left support and an opposite side of the first tread support to the right support.
