ON-SITE TRAILER AXLE MANUFACTURING JIG

A system providing an on-site trailer axle manufacturing jig according to the present invention includes a pair of jig horizontal members, a pair of end cross members coupled between the pair of jig horizontal members about opposing ends, a set of support leg members vertically arranged to support the combination of the jig horizontal members and the end cross members, a pair of attachment wheel assemblies adjustable coupled between the jig horizontal members, and an extending shaft coupled to one of the attachment wheel assemblies for receiving a set of balancing weights to act as a counterweight when manufacturing a trailer axle. Each of the support leg members is coupled to a corresponding leveling adjustment leg, and each attachment wheel assembly has an attachment wheel, a spindle chuck, and a wheel mount spindle. A trailer axle is assembled with a spindle inserted into each spindle chuck to align with opposing ends of an axle member during welding.
