9. Securely tie down the load and attach the winch
cable to the front of the load, if it is not already
attached. Reel in winch cable until it becomes tight.
(Winch cable serves as a safety tiedown in case load
tiedown fails but is not to replace tie downs.)
10. To adjust trailer to a transport position, alternate
between tilting the front of the bed up toward full tilt
position and moving the undercarriage rearward,
until the center of gravity of the trailer load is ahead
of the center of the undercarriage. Keep part of the
load on the wheels and part on the approach plate.
Reel winch out as needed to keep slight tension on
the cable. Never move the undercarriage so far to the
rear that the approach plate is lifted off the ground.
11. When the center of gravity of the trailer and load is in
front of the undercarriage or when the trailer is in full
tilt and the undercarriage as far back as possible
without lifting the approach plate off the ground, fully
lower the tilt angle. Reel in the winch cable as
needed to keep slight tension on the cable.
12. After bed tilt angle is fully lowered, move the
undercarriage to the rear until it is in transport
position. The trailer deck will lower as the
undercarriage rollers go into pockets. Hold
TRAILER
TILT lever in the down position until hydraulic system
works against the bottomed out Hydraulic Tilt
Cylinders (Approximately 2-5 seconds). Hold
AXLE
CONTROL lever in the transport position until
hydraulic system works against the fully extended
Hydraulic Axle Cylinder (Approximately 2-5
seconds).
13. Recheck that load is properly secured. If necessary,
unsecure the load, move load slightly forward or
rearward on the load bed to get correct weight
distribution on kingpin and the trailer axles, and
resecure the load with the tiedowns and winch cable.
14. Shut down hydraulic power system. If hydraulic
engine package is installed, shut down the auxiliary
hydraulic power engine following operating
instructions in
“Hydraulic Power Supply Engine
Operation (Option)” on page 3-20. Assure
maintenance schedule is up-to-date and semitrailer
is ready to be pulled.
Securing the Load

WARNING
1. All items of the semitrailer load must be securely tied
to the deck, front and rear, using the D-rings on the
semitrailer frame. The load must be tied with chain or
ratchet straps sufficient to withstand the weight of the
load using standard approved tiedown methods.
2. No slack is allowed in the tie down chains or straps.
Use binders with chains or a ratchet type buckle on
straps to eliminate any slack in the tiedowns.
IMPORTANT
More information about cargo securement may be
found at
http://www.fmcsa.dot.gov/cargosecurement.pdf.
3. Remember that regulations vary from state to
state. for state regulations, see
http://www.fhwa.dot.gov/webstate.htm.
Tandem axle semitrailer maximum concentrated
load in a 10ft. area is 40,000 lbs. for a standard
semitrailer and 50,000 lbs. with additional
crossmembers. Triple axle semitrailer maximum
concentrated load in a 16ft. area is 70,000 lbs.
1. The semitrailer must be coupled to a tractor
and the landing gear raised off the ground
before operating.
2. Do not exceed the gross axle weight ratings
for any axle on your vehicle. The combined
weight of the semitrailer and cargo must not
exceed the gross vehicle weight rating
(GVWR) of the trailer.
Do not allow slack in tiedowns. A shifting load
may create enough momentum to break hi-test
chains or strap ties. Slack in tiedowns may result
in damage to the load, and death or serious injury
to persons near the load.
