CAUTION
IN LOADING OR UNLOADING POSI-
TION, THE APPROACH PLATE
SHOULD BE RESTING ON THE
GROUND AND THE UNDERCARRIAGE
FULLY FORWARD.
WARNING
ALWAYS USE LOW LOAD ANGLE TO
LOAD AND UNLOAD POWERED
PRODUCTS.
IMPORTANT
MAXIMUM ANGLE IS ONLY INTENDED IF RE-
QUIRED FOR UNLOADING NON-POWERED
PRODUCTS AND TO TRANSFER LOAD TO
TRACTOR. TRANSFER LOAD TO TRACTOR BY
RAISING
DECK
AND
MOVING
AXLES
REARWARD UNTIL LOAD IS FORWARD OF
REAR AXLE, THUS APPLYING LOAD TO TRAC-
TOR.
3-13.8
Winch or drive the load onto the semi-
trailer. Insure that the load is steering straight
up onto the semitrailer and does not maneu-
ver off the side of the semitrailer. Continue
until load center of gravity is just ahead of
the axles, if possible. The load should never
place more weight on the kingpin than on the
rear axles during loading and unloading.
CAUTION
TANDEM AXLE SEMITRAILER MAXI-
MUM 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 CONCEN-
TRATED LOAD IN A 16FT. AREA IS
70,000 LBS.
CAUTION
1. THE SEMITRAILER MUST BE COU-
PLED TO A TRACTOR AND THE LAND-
ING 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.
3-13.9
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 un-
til it becomes tight. (Winch cable serves as a
safety tiedown in case load tiedown fails but
is not to replace tie downs.)
3-13.10
To adjust trailer to a transport position,
alternate between tilting the front of the bed
up toward full tilt position and moving the un-
dercarriage rearward, until the center of
gravity of the trailer load is ahead of the cen-
ter 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 ap-
proach plate is lifted off the ground.
3-13.11
When the center of gravity of the
trailer and load is in front of the undercar-
riage or when the trailer is in full tilt and the
undercarriage as far back as possible with-
out 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.
