Conceptual Innovations designs non-sparking motorized carts to carry flaking rollers with a high degree of accuracy and movement.

Situation

A raw agricultural commodities trader reached out to Conceptual Innovations regarding upgrading their Flaker cart fleet. A Flaker Cart is a type of mobile equipment used in the food industry, specifically in the production of flaked grains. It is typically used to crush oilseeds such as soybeans, canola, and sunflowers into flakes which can be collected in a hopper or bag for transport or further processing.

Flaker carts need to be mobile, as they’re moved to different locations to collect the flakes and for periodic maintenance on the rollers used in processing. This was where some new challenges came to light. Up to this point, the company relied on overhead cranes to move the 16,000-pound rollers onto a cart which a tugger then moved. This also required employees stationed at the corners to help steer the cart.

Now that the company had just moved into their new facility, they quickly found that there wasn’t enough room for all the needed equipment and people to move the rollers.

And the challenges didn’t end there. Besides the logistical problems they faced, one of the most critical challenges working inside a grain processing facility is that the grain dust generated during processing is highly flammable — a volatile situation requiring any transportation vessel to move the grain to be contained entirely to avoid any chance of spark or flame.

Solution

That is when they reached out to Conceptual Innovations. To solve the non-sparking requirements, Conceptual Innovations designed and fabricated a cart to carry the flaking roller in a cradle fashion. Powering the cart required two Drive Casters consisting of five-horsepower, explosion-proof 480 Volt AC motors, and an energy-efficient right-angle gearbox.

Conceptual Innovations also utilized Caster Concepts, a premier Caster Company Specializing in Heavy Duty Casters, for the additional casters used to carry most of the load. These casters were especially suited for this application, consisting of 97 Series Casters with dual swivel sections. These casters allowed an excellent range of movement, thus reducing wheel scrub and less caster binding during direction changes under load.

This system was topped off with a user interface that allowed the operator to control each drive independently, allowing a high degree of control and accuracy when positioning the cart for loading and unloading operations.

Other features of the Drive Caster solution include:

  • High-quality and wear-free helical and bevel gearing
  • Robust UNICASE cast iron housing
  • High-quality helical gearing up to AGMA Class 13
  • High-performance inverter/vector duty motors and brake motors
  • Protective features for severe duty and washdown environments
  • Oil-safe QUADRALIP seal system
  • AUTO VENT breather regulates internal pressure and keeps contaminants out
  • Stainless steel (316) protective paint coating – USDA/HI compliant

The system was topped off with a user interface that allowed the operator to control each drive independently, allowing a high degree of control and accuracy when positioning the cart for loading and unloading operations.

Results

The customer could move the casters easily on their concrete decking. The speed/power of the cart allowed the operators to achieve a high degree of accuracy and safety in a dangerous environment. It also eliminates the need to install additional overhead cranes and multiple people tuggers manhandling a 16,000 lb. load in a space-constrained area.
