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 tie-downs to increase the effect of friction.

General tie-down requirements

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

Run a properly tensioned tie-down through a pipe in an upper tier or over lengthwise tie-downs. It will secure all the pipe beneath it on which the tie-down 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).
