SECURING CARGO
Blocking and Bracing
Blocking is used in the front, back, and/or sides of a piece of
cargo to keep it from sliding. Blocking is shaped to fit snugly
against cargo. It is secured to the cargo deck to prevent cargo
movement.
Bracing is also used to prevent movement of cargo. Bracing goes
from the upper part of the cargo to the floor and/or walls of the
cargo compartment.
Cargo Tiedown
On flatbed trailers or trailers without sides, cargo is required
to be secured to keep it from shifting and falling off. In closed
vans, tiedowns can also be important to prevent cargo shifting that
may affect the handling of the vehicle. Tiedowns need to be the
proper type and proper strength. The combined strength of all cargo
tiedowns must be strong enough to lift one and one half times the
weight of the piece of cargo tied down.
Proper tiedown equipment is required, including ropes, straps,
chains, and tensioning devices (winches, ratchets, clinching components).
Tiedowns must be attached to the vehicle correctly (hook, bolt,
rails, rings).
Cargo should have at least one tiedown for
each 10 feet of cargo. Make sure you have enough tiedowns
to meet this need. No matter how small the cargo is, it should have
at least two tiedowns holding it.
There are special requirements for securing various heavy pieces
of metal. Find out what they are if you are to carry such loads.
Header Boards
Front end header boards (“headache racks”) protect you from your
cargo in case of a collision. Make sure the front end structure
is in good condition. The front end structure should block the forward
movement of any cargo you carry. Covering Cargo
There are two basic reasons for covering cargo,
(1) to protect people from spilled cargo,
and (2) to protect the cargo from weather.
Spill protection is a safety requirement in many states. Be familiar
with the laws in the states you drive in. You should look at your
cargo covers in the mirrors from time to time while driving. A flapping
cover can tear loose, uncovering the cargo, and possibly blocking
your view or someone else's.
Sealed Loads
Sealed loads may be checked by visually checking
the trailer exterior. Look for leaning to one side, tires bulging,
or trailer tires riding low. When in doubt, weigh and then obtain
customer permission to break seal. Reseal after inspection.
Containerized Loads
Containerized loads generally are used when freight is carried
part way by rail or ship. Delivery by truck occurs at the beginning
and/or end of the journey. Some containers have their own tiedown
devices or locks that attach directly to a special frame. Others
have to be loaded onto flat bed trailers. They are secured with
tiedowns just like any other large cargo.
