Driver's Handbook on Cargo Securement - Chapter 13: Large Boulders

What Does This Section Cover?

The requirements in this section apply to any piece of natural, irregularly shaped rock that:

Weighs more than 5,000 kg (11,000 lb.) or has a volume greater than two cubic meters

Is transported on an open vehicle or in a vehicle whose sides are not designed and rated for the transportation of boulders.

Boulders weighing less than 5,000 kg (11,000 lb.) may be secured in one of two ways:

1. Using the requirements for large boulders (this section)

2. In some situations, using the general cargo securement requirements (Section 2) if:

  • Transported in a vehicle designed to carry boulders.
  • Boulders are stabilized and adequately secured by tie-downs.
Rock that is formed or cut to shape and has a stable base can be secured:

Either by the requirements for large boulders.

Or by the requirements for general cargo

Positioning Boulders

Requirements

Place each boulder on the vehicle with its flattest and/or largest side down.

Support each boulder on at least two pieces of hardwood blocking (at least 10 cm x 10 cm (4 x 4 in) that extend the full width of the boulder.

Place hardwood blocking pieces as symmetrically as possible under the boulder so they support at least 3/4 of the length of the boulder.

Requirements

If the flattest side of the boulder is rounded or partially rounded, place the boulder in a crib made of hardwood fixed to deck of vehicle.

Boulder should rest on both deck and timber, with at least 3 well-separated points of contact that prevent rolling in any direction.

If a boulder is tapered, point the narrowest end towards the front of the vehicle.
