Driver's Handbook on Cargo Securement - Chapter 7: Concrete Pipe Loaded Crosswise

What Does This Section Cover?

The specific requirements for concrete pipe apply to the transportation of certain concrete pipe loaded crosswise on a platform trailer or vehicle.

What is exempt from these specific requirements?

Follow general cargo securement requirements (Section 2) when transporting the following pipe:

• Concrete pipe that is grouped together into a single rigid article and may not roll.
• Concrete pipe loaded in a sided vehicle or container.
• Concrete pipe eyes vertical and concrete pipe loaded lengthwise.

What is covered under these specific requirements?

Any concrete pipe loaded crosswise on a platform trailer or vehicle that is not exempt.

Securing Concrete Pipe

To make sure that concrete pipe does not roll or slide:

Load pipe as compactly as possible.

Immobilize symmetrically stacked pipes by securing them in groups.

Use blocking systems and tiedowns to increase the effect of friction.

General tiedown requirements

The aggregate working load limit of all tiedowns on any group of pipe must be more than half the total weight of all pipes in the group.

Run a properly tensioned tiedown through a pipe in an upper tier or over lengthwise tiedowns. It will secure all the pipe beneath it on which the tiedown causes pressure.

Blocking requirements

Blocking must prevent the pipe from rolling or rotating.

Blocking may be one or more pieces placed at equal distances from the center of a pipe

There are two blocking options:

Blocking Option #1

Place one piece of blocking so that it extends at least half the distance from the center to each end of the pipe.

Blocking Option #2

Place two pieces of blocking at the outside quarter points.

Blocking must be:

• Placed against the pipe
• Secured to prevent it from moving out from under the pipe.

Timber blocking must have a minimum nominal dimension of 10 x 15 cm (4 x 6 in).
