In a previous blog, we talked about simple changes you could make to a heavy assembly cart that would improve its maneuverability, and also increase its contributions to a more efficient manufacturing operation.

But often, it’s the most minute of movements that have the greatest impact when trying to position your industrial cart into the precise location it is needed. Though many industrial carts get a “power-assist” by Automatic Guided Vehicles (AGV’s) or Human Operated Tuggers across a distance, it is these short and precise movements that often have to be performed manually.

Movements — such as pulling a cart into the Tugger line or maneuvering a cart from the line to a precise spot at the work area — are handled by humans. This pushing, pulling and turning can require operators to exert greater energy than simply pushing directly forward.

And starting an industrial cart from a dead stop – when we exert the “initial push force” – can be the most challenge operation of all.

That’s when TWERGO® — the patented industrial caster we developed here at Caster Concepts, featuring a patented parabolic face and independently rotating wheels – is at its most appreciated. TWERGO® (which stands for Twin Wheel Ergonomic) is designed to produce a 25 percent reduction in forces needed to start, stop, turn and maneuver*.

The independently rotating wheels on the TWERGO® industrial caster reduce friction by allowing the wheels to rotate in the direction and amount needed to turn and maneuver.  The parabolic face design with tapered tread design reduces the amount of force exerted to start rolling.

By using multiple thinner wheels in a tandem operation, TWERGO® reduces the amount of wheel-to-floor surface contact and allows each wheel to spin independently. The independent spinning functionality lets each wheel turn in the direction and amount that promotes minimal friction.

One last note – a heavy-duty industrial caster like TWERGO®, which achieves reduction in force by mechanical design, is a decided advantage over other industrial wheel designs, such as balloon or donut wheels, which reduce force by rounding the ends of the tread material. While this rounded end design achieves some reduction in force when turning, that force reduction will diminish as the tread material wears.

Therefore, the benefit achieved by these wheels is limited; where as TWERGO®’s mechanical functionality is not. TWERGO® is built to last, with precision sealed ball bearing units, more durable tread material and a tapered tread design.

*25% reduction in force based on in house testing verses conventional casters. Actually performance will vary depending upon various factors including cart design, handle placement, load weight distribution and other factors. Users have claimed as much as 50% reduction in initial push force in their specific application.

“Individual results vary depending upon several factors, including cart design, load weight distribution, handle height and other factors. 25% is average of testing, users have reported reduction in initial push force by as much as 50%.”
