Lumber

Bundles 3 or more tiers high:

  1. Place a 4×4 timber under the front of the front bundle when loading. (red in figure 2)
  2. Place a 4×4 timber under the rear of the rear bundle. (red in figure 2)
  3. Secure each bundle on the second tier with two 4-inch straps. (orange in figure 2)
  4. Secure each bundle on the third tier with two 4-inch straps.
  5. X-Straps should be added to the front and rear to prevent shifting.
Figure 2: 3 tier lumber load. Notice the orange belly straps over the second layer. Without the orange straps,
this load is not legal. X-straps to prevent shifts are seen in blue.

Points to Remember:

  • All straps used on the load should have edge protectors in place.
  • Blocking or spacing between layers cannot be taller than it is wide. This creates unstable layers that will roll forward during hard breaking and cause any tie-downs on the load to become loose. 
  • If there are more than 3 tiers a belly strap must be used on one of the lower levels no more than 6 feet off the deck of the trailer. 
  • X-straps can be over or under the tarp.
