A vinyl manufacturer had a giant bottleneck on the line that literally rested on the backs of its workers to resolve—a scenario so rife with risks and safety issues that it could only ever end in disaster.
The problem was this: every day, a small team of workers was responsible for unloading giant, unwieldy pallets of vinyl rolls. These rolls—measuring up to 6-feet long and weighing up to 1,200 pounds—had to be rolled off the pallet, propped up on end, and wheeled into cold storage without the aid of any powered equipment.
This meant that workers had to perform this job without crushing their hands or feet, without destroying their backs and shoulders, and without damaging the product in the process. All of which is, if not impossible, at least improbable in the long term.
The biggest issue for them was that there was nothing on the market that could replace this human effort—there was no off-the-shelf material handling system available anywhere that could somehow lift these soft rolls, manipulate them into position, and also transport them where they needed to go.
They were stuck.
This is a common issue faced by manufacturers. With all of the new equipment available today—all these robots and sophisticated material handling systems—some jobs are just too specific and too complicated for generic solutions.
So this company did what many do in this situation: they called the customization experts.
"Customers come to us with complicated problems," explains Ryan Blesi, vice president material handling division at Nu-Star, Inc. "They don't have a particular solution or machine in mind, though. They say, 'Here is what we have, tell me what you can do for us.'"
This, he says, has become a fairly standard occurrence at Nu-Star over the years. And for good reason.
On the face of it, Nu-Star is a material handling company. It sells a few core technologies—most notably, the PowerPusher and the PowerTug—designed to help move incredibly heavy material with incredible ease.
While these tools are impressive on their own, what really makes the company interesting is the custom engineering it does on top of them.
"Most of the machines we sell have been customized to fit exactly the application it is being used for," Blesi explains. "The drive wheel remains the same, the handle remains the same, but what comes off the front of the machine may be totally different."
This customization, he says, is all in the attachments. Nu-Star works closely with clients to design and build custom end pieces—giant lifting contraptions, claws, cranes, and everything else imaginable—that are engineered to handle specific materials and specific issues.
This can mean moving airplanes or cars on the production line; it can mean pulling trains and preposterously large metal coils. Or, it could mean carrying the load for vinyl makers.
The answer for this vinyl problem came in the form of the MFC-100—Nu-Star's powerful lifting and pulling tool designed for heavy, awkward pieces like this.
The core device can lift up to 5,000 pounds and push/pull up to 15,000 pounds and is equipped with all of the power controls for easy transport that Nu-Star is known for.
Nu-Star also designed a custom attachment designed to carefully squeeze and lift these rolls right off the pallet to finally take the strain out of the job.
"With our machine, they are able to go into the pallet at an angle and attach a special strap," Blesi explains. "They squeeze the roll at that point, pick it up and then use the machine to walk it to the area they need to store it in."
This system, he says, removes all of the safety concerns the workers had been enduring.
"Using this powered equipment, it takes the back issues away, it takes the shoulder issues away, it takes away anything that may require force on your body to get the load moving," he says. "Just squeeze the handle and let the machine do its work."
At the same time, he says, the system cuts the task down from a three-person job to just one.
This kind of case study, Blesi argues, is the real benefit his company offers in these situations.
"Our equipment has built a strong reputation in the market," he explains. "That's because we put time into getting the right equipment to every customer, and time putting the right attachment on it, and then backing it up once it's done and in service."
