Securing Pipe with an Inside Diameter Up to 1143 mm (45 in)

Concrete pipe loaded crosswise generally:

• At least one tiedown 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.
• Note: At least one tiedown 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.
• 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.
• All of these things apply.

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?

• 6
• 3
• 10
• 15

As a group

Place lengthwise tiedowns 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

Place one crosswise tiedown for every 3.0 m (10 ft) of load length.

Either attach the side-to-side tiedown through a pipe

Or pass the tiedown over both front-to-back tiedowns between two pipes on the top tier.

When securing concrete pipe with a diameter up to 45 inches loaded crosswise as a group,lengthwise tiedowns should be either one 1/2 in chain or wire rope, or:

• Two nylon straps with aggregate WLL of 50% the weight of the load.
• One 3/8 inch chain or wire rope.
• Two 1/4 inch chains or wire ropes.
• Two 3/8 inch chains or wire ropes.

When securing concrete pipe up to 45 inches loaded crosswise, tiedowns through the pipe must be:
