2.3.7
Unsafe Load Distribution
Improper front/rear load distribution can lead to an unstable trailer or poor tractor handling. Poor
trailer stability results from fifth wheel weights that are too low, and poor tow vehicle stability results
from fifth wheel weights that are too high.
After loading, be sure to check that none of the axles are overloaded.
Uneven left/right load distribution can cause tire, wheel, axle or structural failure. Be sure your trailer
is evenly loaded left/right. Towing stability also depends on keeping the center of gravity
as low as
possible.
Improper tongue weight (load distribution) can result in loss of control of the trailer, leading to death
or serious injury.
WARNING! Make certain that axle weights are within the allowable range.
Be sure to:
•
Distribute the load evenly, right and left.
•
Keep the center of gravity low.
•
Distribute the load front-to-rear to provide proper suspension weight.
2.3.8
Shifting Cargo
Since the trailer “ride” can be bumpy and rough, you must secure the cargo so that it does not shift
while the trailer is being towed.
WARNING! A shifting load can result in failure, or to loss of control of the trailer, and can
lead to death or serious injury.
You must tie down all loads with properly sized fasteners, chains, straps, etc. to prevent
the load from shifting while towing.
