Abstract
An improved suspension that may be used in any dynamically loaded beam structure, such as a trailer chassis. Specifically, an improved spring hanger and method for attachment are discussed, in which the improved spring hanger is welded to the web of a support beam, where stresses are lower, as opposed to the bottom flange thereof. Methods are provided for welding the spring hanger to said beam alongside as well as in contact with existing, transverse support members.
