TRANSPORTING LOADS - Continued
CAUTION
DO NOT over steer during small radius turns. Know the position
of the fifth wheel towing device in conjunction with the prime
mover. Failure to comply may result in vehicle contact between
the fifth wheel towing device and the primemover and may cause
damage to equipment.
e. Turning. When turning corners, allow extra room. The towed vehicle wheels will follow a
track that is inside the radius of the prime mover wheels. For right turns, drive about halfway
into the intersection and then cut sharply to the right. The forces affecting the stability of a
tractor combination are increased during turning. The smaller the radius, the greater the force
trying to pull the vehicle over. Therefore, the tighter the curve, the slower the speed must be
in order to avoid a rollover.
WARNING
Stopping distances greatly increase when the towed vehicle has
nonfunctioning brakes. Care should be taken to ensure adequate
stopping distance is obtained and speed is adjusted accordingly.
Failure to comply may result in injury or death to personnel.
Towing of a single vehicle with non-functioning brakes must be
limited to not more than 25 mph on the highway and 15 mph off-road.
Failure to comply may result in injury or death to personnel.
Towing of vehicle combinations with non-functioning brakes is
prohibited. Failure to comply may result in injury or death to
personnel.
Stopping. In normal operation, brake pressure should be applied gradually and smoothly.
f.
Selecting a lower gear before beginning a long downgrade is the safest, most effective way
to maintain control of the vehicle combination.
g. Parking. When the prime mover and the towing device are to be parked and left unattended,
set the parking brake on the prime mover and place chock blocks in front and behind wheels
to prevent rolling.
WARNING
Visibility from the prime mover is significantly reduced when
backing. Proper procedures must be followed and extreme
caution used when backing to prevent damage to equipment and
injury or death to personnel.
h. Backing. When backing, use the assistant driver as a ground guide. Adjust rear view mirrors
before backing. Use slow speed and extreme caution when backing this combination.
