Concrete pipe with an inside diameter up to 1.143 m (45 in) can form a complete single tier on a typical flatbed vehicle. Larger pipe often can only be carried as a partial tier.
Note: This pipe diameter of 1.143 m (45 in) is simply a convenient breaking point between "medium" and "large" diameter pipe.
Note: At least one tie-down through the front pipe of the bottom tier must run rearward at an angle not more than 45 with the horizontal when viewed from the side of the vehicle, when ever practical.
At least one tie-down through the rear pipe of the bottom tier must run forward at an angle not more than 45 with the horizontal when viewed from the side of the vehicle, when ever practical.
Arrange the load properly
Run a tie-down though the pipe.
Place lengthwise tie-downs over the group of pipes:
Either one 13 mm (1/2 in) chain or wire rope,
Or two 10 mm (3/8 in) diameter chain or wire rope
Either attach the side-to-side tie-down through a pipe
Or pass the tie-down over both front-to-back tie-downs between two pipes on the top tier.
When securing concrete pipe with a diameter up to 45 inches loaded crosswise as a group, a crosswise tiedown should be used every how many feet?
