Huhtamaki, headquartered in Finland, is a global provider of sustainable food packaging solutions. With major customers coast-to-coast, including Walmart and some of our country’s largest fast-food providers, all 18 facilities in the United States are busy.

Huhtamaki owns several factories in Ohio that also remain busy. Their two factories located in New Vienna, Ohio specialize in the manufacture of plastic Chinet tableware (cups and plates) as well as ice cream lids, and their manufacturing processes rely heavily on large die-casting presses. plastic injection. When the change requires a new mold or when problems arise requiring mold repair, time is of the essence. In the past, Huhtamaki relied on contractors and riggers. Availability, timing and prices varied, all of which could be problematic. More importantly, Huhtamaki did not have full control over his manufacturing process.

How NOMAD Cranes Solved Problems

NOMAD self-supporting cranes solved the problems and eliminated the need for outside contractors, putting control back in Huhtamaki. To date, EMH has installed four low headroom, high capacity (20-25 ton) NOMAD self-supporting crane systems in each of Huhtamaki’s four main production halls. Huhtamaki now resolves issues quickly and replaces molds on its own schedule. The company is no longer at the mercy of outside contractors and riggers. Price variations are no longer a problem either.

NOMAD cranes also solved other problems. For example, when contractors and riggers were commissioned before, typical rigging stresses required workers to lift and remove heavy molds from injection molding machines at an angle. Since the weight of the molds varied from around 7,000 pounds to 55,000 pounds, getting them out of the machine at an angle was not an easy task and could be problematic. The rigging crews had to do their job with precision. Slight bumps could cause problems. The self-supporting NOMAD cranes easily solved the problem because the cranes could be assembled and positioned so that the molds could be lifted perpendicular to the ground, or straight up for easy removal and replacement. Additionally, if a change in machine position was required, self-supporting cranes could also accommodate this. The base plate design allows most NOMAD systems to be installed without legs. And with a bolted assembly, NOMAD self-supporting crane systems are easily dismantled, moved and reassembled as needed.

NOMAD cranes are available for one, two, three or four cell manufacturing systems, with safety closed type track electrification, brackets welded to track support columns and field installed busbars. Each system comes complete with mounting plates, bolts and bumpers and with maximum end carriage travel speeds of 80 or 120 FPM (VFD). Wire rope hoists offer hoisting speeds of 16/2.6 ft/min with carriage speeds of 65 ft/min (VFD). Bridge conductor cables are pre-wired on quick-disconnect plugs. NOMAD cranes are delivered as standard with a radio remote control. Each system comes with an AAA handheld radio controller. Rechargeable models are optional. An emergency push-button station can be supplied as an option.

Extra large NOMAD cranes

An EMH NOMAD XW (extra large) custom self-supporting crane was EMH’s most recent solution for Huhtamaki in New Vienna. EMH tailored it to the company’s specific layout, with a length of 250 feet and a span of 50 feet. Column spacings varied to accommodate the production floor. There were no headers to maximize hook height on the system. EMH also provided a stepped box girder, allowing the hoist to pass between the bridge girders, maximizing lift above the injection molding machines, but below the roof trusses.

The crane’s capabilities also eliminated other problems. Thanks to the bolted connection and flexibility, EMH was able to best position the crane to optimize Huhtamaki’s floor space. Then, as the crane could be assembled, disassembled and reassembled so easily, repositioning the crane was not a problem. According to a Huhtamaki MCP manufacturing engineer, “EMH had to move the crane about three or four times to get the crane columns into the exact position we wanted, and since the foundation floor wasn’t perfectly level, EMH had to shim and adjust some of the columns to get the crane perfectly level, and within 10 days the self-supporting crane was fully tested and fully operational.

Commenting on the performance of NOMAD self-supporting cranes in general, the same engineer said, “We have been extremely pleased with EMH and their self-supporting cranes. We now have one placed above every plastic injection molding machine in our factory and have never had a problem. That’s why we never considered another crane solution from another manufacturer. We are particularly pleased because we sometimes squeeze these cranes to lift some of our heaviest molds, which are close to the crane’s recommended weight limit. We have never had a problem. »
