OPERATING INSTRUCTIONS
CAUTION
WARNING
8. 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.)
9. Before returning trailer to transport position, return air
ride suspension switch to transport (off) position.
10. Using Axle/Tail Control Lever, move the
undercarriage to the rear until it is in transport
position. The tail deck will raise as the undercarriage
moves into the transport lock position. Hold Axle/Tail
Control Lever in the transport position until hydraulic
system works against the fully extended Hydraulic
Axle Cylinder (Approximately 15-30 seconds.)
11. 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.
12. 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 3-21.
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.
Remember that regulations vary from state to state.
for state regulations, see
http://www.fhwa.dot.gov/webstate.htm.
Model 930 semitrailer maximum concentrated
load in a 10ft. area is 50,000 lbs. Model 950
semitrailer maximum concentrated load in a 10ft.
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.
