OPERATING INSTRUCTIONS
3-7
6.
Winch or drive the load onto the semitrailer. Insure
that the load is steering straight up onto the
semitrailer and does not maneuver off the side of the
semitrailer. Continue until load center of gravity is just
ahead of the axles. The load should never place
more weight on the kingpin than on the rear axles
during loading and unloading.
CAUTION
WARNING
WARNING
7.
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.)
8.
If the load center of gravity is not ahead of the rear
axle, alternate between tilting the front of the bed up
and moving the undercarriage to the rear, until the
center of gravity of the semitrailer load is in front of
the rear axle. Keep part of the load on the wheels
and part on the approach plate. Never move the
undercarriage so far to the rear that the approach
plate is lifted off the ground during this procedure.
9.
When the center of gravity of the semitrailer and load
is in front of the rear axle, fully lower the tilt angle.
10. After bed tilt angle is fully lowered, move the
undercarriage to the rear until it is in transport
position. Hold
TRAILER TILT
lever in the down
position until hydraulic system works against the
bottomed out Hydraulic Tilt Cylinders. Hold
AXLE
CONTROL
lever in the transport position until
hydraulic system works against the fully extended
hydraulic axle cylinder.
11. If necessary, unsecure the load, move load slightly
forward or rearward on the load bed to get correct
weight distribution on kingpin and the semitrailer
axles, and resecure the load with the tiedowns and
winch cable.
12. Shut down the auxiliary hydraulic power engine
following operating instructions in
Hydraulic Power Engine Operation” on
page 3-11.
13. Recheck that the load is properly secured. 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 to the semitrailer frame.
The load must be tied with chain or 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.
remember that regulations vary from state to state.
For state regulations, see
http://www.fhwa.dot.gov/webstate.htm.
Maximum concentrated load is 10,000 lbs. in a 10
ft. area for a single axle semitrailer and 20,000
lbs. in a 10 ft. area for a tandem axle semitrailer.
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.
The center of gravity of the load must be in front
of the center of the undercarriage whenever the
approach plate is not supported by the ground.
Failure to do this can cause the semitrailer to tilt
back resulting in injury or death.
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.
