OPERATING INSTRUCTIONS
3-13
Unloading Procedure
1. Practice all standard industrial safety standards.
2. Park the tractor/semitrailer in a straight line on a level
even surface
Set the tractor brakes
and release the semitrailer brakes.
3. Start operation of hydraulic power system. If the
hydraulic engine package is installed, start and warm
up the auxiliary hydraulic power engine following
engine operating instructions in
Supply Engine Operation (Option)” on page 3-21.
WARNING
4. Move load as far forward as is practical on the trailer
and secure with appropriate load tiedowns.
5. Using the Axle/Tail Control Lever
,
move undercarriage forward until approach plate
touches the ground.
6. Switch the air ride suspension to lower
(ON)
position
to achieve the lowest load angle.
WARNING
7. If load is non-powered, insure that the winch cable is
firmly attached to the load and tension is on the
cable. Lower tail deck according to
steps 5 through
adjusting tension on winch cable as required. With
winch cable firmly attached to load and sufficient
tension on the cable so load securing devices can be
safely removed, remove other load securing devices.
Use the winch to assist the load down to end of
approach plate. With end of load resting on ground,
block load from rolling or sliding, if necessary.
Disconnect the winch and move the trailer from under
the load, allowing the load to move off trailer to the
ground.
8. If powered load is secured to lower deck only, lower
tail deck according to
Make sure the tail deck
is tilted to the low load angle. Check that powered
equipment parking brakes are set and winch cable
hooked to powered equipment with sufficient tension
so load securing devices can be removed. Remove
safety securing devices. Take tension off winch cable
and remove winch cable. Power load off the trailer.
WARNING
9. If powered load is secured to both tail and lower
deck, attention is required before lowering tail deck.
Adjust load securing devices to allow tail to tilt and
sufficiently secure load from movement while tail is
tilted to low load angle.
10. Before returning the semitrailer to transport position
insure that there is sufficient distance between the
load and the rear of the semitrailer so that the
semitrailer does not hit the load when being folded
back to transport position.
CAUTION
11. Using Axle/Tail Control Lever, move undercarriage
rearward to transport 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.)
12. Reel in winch cable and secure hook on upper deck.
13.
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.
Work Light (Option)
The Work Light Switch is on the hydraulic control panel
It illuminates the hydraulic control
panel and controls the optional work lights mounted on
the bulkhead. The work lights illuminate the upper deck.
When load is on tail, do not lower with load
secured to main deck. When load is on main
deck, do not lower tail with load secured to tail.
Always use low load angle to load and unload
powered products.
When removing load, insure that the load is
steering straight so it does not maneuver off the
side of the semitrailer. Failure to do so could
result in damage to equipment, injury, or death.
Before returning the semitrailer to transport
position, insure that there is sufficient distance
between the load and the rear of the semitrailer.
Failure to do so may result in damage to the
semitrailer and/or load.
