The Uni-Wheel was designed to help with lines being messed up due to potholes, and/or rumbles on either side of the road. This also includes the centerline as many roads have rumbles and potholes in the center. By removing one of the carriage wheels there is no reason to make adjustments to the carriages when encountering either of these obstacles. In the past, the operator would need to take their eye off the whole operation for a few minutes to adjust the wheel. A lot can happen in a few minutes. It also eliminated some down time, as we were having to deal with flat tires on the carriage.
Benefit and Implementation
With the Uni-Wheel, you add quality to the line and less downtime which adds quantity, and you never need to take your eye off of the operation and allows operator to be safe.
