3-18 UNLOADING THE LOWER DECK

WARNING

1. THE SEMITRAILER MUST BE COU-

PLED TO A TRACTOR AND THE LAND-

ING GEAR RAISED OFF THE GROUND

BEFORE OPERATING.

2. DO NOT OPERATE TRAILER HYDRAU-

LICS UNLESS TRACTOR BRAKES ARE

LOCKED.

WARNING

DO NOT EXCEED THE GROSS AXLE

WEIGHT RATINGS FOR ANY AXLE ON

YOUR VEHICLE. THE COMBINED

WEIGHT OF THE TRACTOR, SEMI-

TRAILER, AND CARGO MUST NOT EX-

CEED THE GROSS VEHICLE WEIGHT

RATING (GVWR) OF THE TRACTOR.

3-18.1

Insure that the winch cables are firmly

attached to the vehicles and sufficient ten-

sion is on the cables so load securing chains

can be safely removed.

3-18.2

Unlock and raise any of the arms nec-

essary so that all vehicles on the lower deck

will clear the upper deck while unloading.

3-18.3

Move the axles forward.

If the load cannot be driven and must be slid

off the trailer, move the undercarriage forward

just enough to allow the rear edge of the

lower deck to touch the ground, when the

trailer is fully tilted.

If the load can be driven off the trailer, the

lowest possible load angle is desirable. Move

the undercarriage forward as far as possible.

3-18.4

Tilt the trailer up until the approach

plate touches the ground.

3-18.5

With load securing devices removed,

reel out the winch on which the rear most

vehicle is attached so that the vehicle moves

back towards the rear of the semitrailer. In-

sure that the load is steering straight so it

does not maneuver off the side of the semi-

trailer.

WARNING

WHEN REMOVING LOAD, INSURE

THAT THE LOAD IS STEERING

STRAIGHT SO IT DOES NOT MANEU-

VER OFF THE SIDE OF THE SEMI-

TRAILER. FAILURE TO DO SO COULD

RESULT IN DAMAGE TO EQUIPMENT,

INJURY, OR DEATH.

3-18.6

After the vehicle is completely off the

rear of the semitrailer disconnect the winch

cable and store it on the lower deck.

3-18.7

Move the vehicle out of the way or

move the semitrailer away from the vehicle.

3-18.8

Repeat

steps 3-18.5 through 3-18.7

until the lower deck is unloaded.

3-19 UNLOADING THE UPPER DECK

3-19.1

Insure that the winch cables are firmly

attached to the vehicles and sufficient ten-

sion is on the cables so load securing chains

can be safely removed.

3-19.2

Unlock and lower the front arm as far

down as it will go.

3-19.3

Unlock and lower the rear arm until the

back edge of the upper deck touches the

lower deck.

3-19.4

steps 3-18.3 through 3-18.7

for

unloading the vehicles.
