A device placed between the deck of a vehicle and car or between articles of cargo, intended to provide greater friction than exists naturally between these surfaces is:

• A friction mat.
• Void filler.
• A cleat.
• A chock.

If loading and securing paper rolls on a second layer:

• Lay the second layer horizontally.
• Make sure heavier rolls are on top.
• Be sure the bottom layer extends to the front of the vehicle.
• Stack the second layer at the back.

A container chassis vehicle is defined as:

• A reusable, transportable enclosure that is especially designed with integral locking devices that secure it to a container chassis trailer to facilitate the efficient and bulk shipping and transfer of goods by, or between various modes of transport, such as highway, rail, sea, and air.
• A specialized container, primarily used to contain and transport materials in the waste, recycling, construction/demolition, and scrap industries, which are used in conjunction with specialized vehicles, in which the container isloaded and unloaded onto a tilt frame body by an articulating hook-arm.
• A vehicle especially built and fitted with locking devices for the transport of intermodal containers.
• A structure, device, or another substantial article placed against an article to prevent it from tipping that may also prevent it from shifting.

To prevent rolling, how many points of contact are required, at minimum, for a boulder resting on a rounded or partially rounded side?

• 2
• 3
• 5
• 4

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.

When using tiedowns to secure boulders, all of the following are requirements except:

• Use only chain to secure large boulders.
• Tiedowns should be located in valleys or notches across the top of the boulder.
• Tiedowns must be arranged to prevent sliding across the rock surface.
• Boulders must be loaded as far back towards the rear as possible.

Requirements

Use only chain to secure large boulders.

Tiedowns in direct contact with the boulder:

Should be located in valleys or notches across the top of the boulder

Must be arranged to prevent sliding across the rock surface.

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?

• 3
• 6
• 15
• 10

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 loading and securing a boulder, it should be:

• All of these are requirements.
• Placed on symmetrical hardwood blocking that extends 3/4 of the length of the boulder.
• Supported on at least 2 pieces of 4in x 4in hardwood blocking, extending the full width of the boulder.
• Placed on the vehicle with its largest or flattest side down.

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.

Define 'bolster':

• A vertical barrier across the front of the deck of a vehicle to prevent forward movement of cargo.
• An inflatable bag intended to fill otherwise empty space between articles of cargo, or between articles of cargo and the wall of the vehicle.
• A crosswise load bearing structural component, particularly a part of a log bunk.
• A structure, device, or another substantial article placed against or around an article to prevent horizontal movement of the article.

Aggregate Working Load Limit is defined as:

• The maximum load that may be applied to a component of a cargo securement system during normal service, usually assigned by the manufacturer of the component.
• A combination of securing devices which form an assembly that attaches cargo to, or restrains cargo on, a vehicle or trailer, and is attached to anchor point(s).
• The maximum weight of a load of rocks that a securement device can withstand.
• The summation of the working load limits or restraining capacity of all devices used to secure an article on a vehicle.

When loading paper rolls with eyes horizontal, which of the following is not a requirement for stacking a second layer:

• All the wells in the layer beneath must be filled
• The bottom layer must extend all the way to the front.
• Place second layer with eyes vertical.
• It must be blocked against an eye-vertical blocking roll resting on the floor of the vehicle that is at least 1.5 times taller than the diameter of the roll being blocked.
