These tools are used to create a separation between the metal coil and the cover. Ramp bearings are usually made from 4×4 or 6×6 pieces of wood, often built of oak, and have a slight slope, usually around 12.5 degrees. This gentle gradient encourages the rolling edge of the coil to settle down, preventing lateral movement.
In addition to ramp bearings, coil racks are a common choice. These steel structures are placed on the trailer and are equipped with vertical steel columns several inches high. These columns are inclined to suspend the coil and prevent rolling. Typically, one rack is needed for each 10,000 pounds of weight
Friction bearings and wedges also play a vital role in the process.
- Friction bearings: These rubber pads are placed on the deck, effectively preventing movement and sliding of the ramp pads or reel racks.
- wedges: Located on the outside of the ramp pads, these taller blocks serve as a physical barrier to stop rolling.
Effective use of these tools and techniques ensures the safe transportation of metal coils.
