The new MAC Trailer plant is under the direction of Jeff Sheen, general manager of MAC’s refuse equipment division; Mike Conny, president of MAC Trailer; and Tate Ray, plant manager.
High on the wish list when MAC Trailer was designing the new plant: minimum movement of components and raw materials. With fabrication and subassembly production nearby, the forklift does not have far to travel.
Transfer trailers are the primary product produced at the new plant. Separate lines produce high-volume standard trailers and highly customized refuse haulers.
The plant is set up to manufacture external sheet-and-post trailers and smooth-side designs.
Assembly lines are similar, with refuse and end-dumps both starting the assembly process being built upside down.
Live floors are completed before the walls are installed.
Once the trailers are completed, they are inspected and the tare weight is determined.
Half-round end dumps are another product line manufactured in the new MAC plant.
Subassemblies are produced near the point where they are needed on the assembly line.
Upper coupler assembly is one of the few steel components used in what is predominantly an aluminum trailer plant.
Like a giant rolling pin, this roller moves across the table to provide the radius on MAC half-round dump trailers.
Half-round dumps are assembled in a fixture engineered and built by the MAC research and development team.
Dump box of the MAC half-round end dump is assembled almost completely upside down.
As is the case with the refuse trailer production process, subassemblies required for half-round end dumps are assembled as close as possible to where they are required on the assembly line.
Assembled dump boxes move to the finishing station for plumbing, wiring, and other items such as conspicuity tape.
MAC purchased 77 Fronius welding machines. Management says the Austrian company’s welders are exceptionally energy efficient—not surprising for a company that is also involved in battery charging systems and solar energy.
A new Messer CNC plasma table fabricates the steel components that go into MAC refuse and half-round trailers. President Mike Conny likes the fact that the parts cut on the machine require no secondary processing.
A CNC router cuts aluminum parts from sheet. Like the plasma table, the router produces an edge that requires no grinding. As production demands, MAC plans to install the optional automated sheet handling system that will enable the plant to produce parts automatically overnight.
