Working outside the box: Robinson Custom Enclosures pushes the boundaries in development and fabrication of machine enclosures

It's very easy for even the most successful companies to become pigeonholed, associated in people's minds as specializing in just one small area. For example, when considering Robinson Custom Enclosures, what no doubt comes to mind for a lot of people is the image of a company that focuses on enclosures for smaller generator set packages, primarily in the Midwest.

That's accurate as far as it goes. Yet in reality, that image of Robinson misses the full range of capabilities the De Pete, Wis., company can bring to the table by a wide mile. Robinson can supply highly engineered enclosures for packages in excess of 2 MW and can build and outfit trailers and containers of all sizes--and not just for power generation systems, as demonstrated by a specialized enclosure designed for a global manufacturer of railway maintenance equipment.

"Before I got here in 2001, they really didn't have anyone in sales," said David Oshefsky, national sales manager at Robinson. "They had sold everything through word of mouth and reputation

What the company can do is perhaps best exemplified by some of the things it has already done. "We had one order where we fabricated 48 ISO containers in six weeks," said Oshefsky. "We did not hire any welders, we did not get any temporary labor to do it. We ramped up in three days, pulled anyone we could from the lab business, from heating and cooling and manufacturing and we got them all done in that time."

"That goes to the quality of our workforce," said Tom Verboncouer, Robinson's marketing manager. "We have a talent pool in house that really is unique. Most all of our people are cross-trained. They can weld, they can fabricate, they can do just about every job that needs doing. That's how we can respond so well to those kinds of situations."

An even more recent example--and one that aptly demonstrates that Robinson is not exclusively tied to the power generation industry--involved a contract with Holland Co. LP, a leading manufacturer of track maintenance equipment. Holland, headquartered in Crete, Ill., produces a line if mobile track welders with dual-purpose highway and rail chassis.

When the company began looking at selling mobile rail welding equipment into the European markets, it found that its products were essentially too large to fit into smaller European rail tunnels. In addition, its conventional fiberglass reinforced plywood body style was too heavy to accommodate European vehicle weight restrictions.

Holland's previous experience with rental generators led it to Robinson. "The Holland Mobile Rail Welder was definitely an interesting project," said Oshefsky. "The entire package needed to be built very robust in order to handle rail transportation, yet be light enough to meet the stringent weight requirements of the highways.

"This combination usually doesn't mix well, especially when you add in the height requirements of the European tunnels, both on the rail and the highways."

Robinson engineered an enclosure constructed of 1/8 in. aluminum with formed, seam-sealed panels to prevent leakage, as well as allow the unit to fit into the tight rail tunnels. While the goal was to manufacture a vehicle weighing less than 30 tons, the lightweight enclosure helped it come in at 25 tons. In addition, the unit is sound attenuated, helping the machine reduce noise emissions by some 20 dB(A).

"Robinson met all of our demands without question," said Dennis E. Gibbs, senior mechanical engineer at Holland. "They came through on their promise to deliver, from timeframe to budget."

Robinson's enclosure design also managed to reduce assembly time, Gibbs added. In most cases, assembly of a custom enclosure on a custom chassis can take as long as three weeks. In this case, the union took just three days.

"All they really had to do was set the container over the locks and attach the fuel lines," said Gibbs. "In a matter of three days, it went from a stack of several parts to one unit that was very functional. They picked it up, put it on the truck and it fit.

"It was a job well done on Robinson's part--everything was custom made, fit together and complete."

That kind of versatility could be expected from a company with Robinson's heritage. The company was founded in the mid-1970s as Robinson Metal and Roofing, a specialist in roofing, sheet metal fabrication and heating and cooling. In time, the roofing business was sold off and the company evolved into Robinson Metal, Inc. consisting of four divisions, one of which is Robinson Custom Enclosures. The other four business activities are metal fabrication, machining and heating and cooling.

The Custom Enclosures business grew to encompass small trailers and sound-attenuated weather protection enclosures as well. The company's product line includes drop-over or skid-mounted generator set housing styles, with aluminum, stainless-steel or galvanealed construction. Custom turnkey packages can be skid- or trailer-mounted, with or without accessories enclosed
