2-12 – Triple-L-Trailer – 3121224
DO NOT TRANSPORT FLAMMABLE, EXPLOSIVE, POISONOUS OR
OTHER DANGEROUS MATERIALS IN YOUR TRAILER. EXCEP-
TIONS ARE: FUEL IN THE TANKS OF EQUIPMENT BEING
HAULED, FUEL STORED IN THE TANK OF AN ON-BOARD GEN-
ERATOR.
Preparing the Trailer for Loading
Before loading cargo onto the trailer:
Chock wheels on the left and right sides of the trailer to
prevent movement to the front or rear while loading.
Inspect the deck of the trailer (and the interior, if trailer is
enclosed) for corrosion or damage, and Inspect the hold
down openings, “D”-rings and/or track system used to
secure loads. Hold down openings must be sturdy with no
visible cracks or kinks. D-rings and track systems must be
tight and must not be bent.
If the deck or any required hold-down is damaged, do not
load the cargo. Bring the trailer to your dealer or a compe-
tent repair service before using it to carry cargo.
INSPECT “ D”- RI NGS, AND TEST THEM FOR LOOSENESS
BEFORE LOADING CARGO. DO NOT USE A DAMAGED OR
LOOSE “D”-RING TO SECURE CARGO.
Loading the Trailer
Triple L trailers are equipped with a hydraulically lowered
deck instead of ramps. The lowering deck feature allows
for easier loading and unloading.
When loading the trailer:
• Read all trailer decals before loading.
• Be sure all personnel are clear when raising or lower-
ing the deck.
• Never exceed the capacity of the trailer.
• Always center the load side-to-side and load to the
proper tongue weight.
• Confirm correct coupler height when loaded.
• Never allow "rear-heavy" loads. This will cause sway
and loss of control.
• After raising the deck, make sure the travel latch is
engaged and locked.
• Be sure the cargo is securely tied to the deck. Do not
tie to the outer frame.
DO NOT TRANSPORT PEOPLE ON OR INSIDE THE TRAILER. THE
TRANSPORT OF PEOPLE PUTS THEIR LIVES AT RISK AND MAY
BE ILLEGAL.
The hydraulically lowered trailer deck is fitted with a travel
latch that keeps the trailer in the driving (up) position. After
the trailer is loaded, the cargo is secured with hold-downs,
and the deck has been raised to the travel position, be
sure the travel latch has locked the trailer deck into place.
Couple the trailer securely to the tow vehicle before
attempting to unlock the deck and load the trailer. Be sure
all personnel are clear when lowering deck.
Unlatch and hold the travel latch. Move the "up/down"
control handle to the “down” position. Move the control
handle slowly to "feather" or control the speed of lowering.
The travel latch may be released once the deck starts to
lower.
The deck alarm is designed to give intermittent beeps as
the deck is lowered. The alarm should sound automati-
cally when the deck control lever is moved to the "down"
position.
If equipped, open the gate or door of the trailer. After the
trailer deck has been lowered to the ground, the trailer
may be loaded. Ensure that the load is centered side-to-
side and forward to where approximately 10% - 15% of the
total load is positioned at the trailer tongue.
Secure the properly positioned load by tying it to the
trailer deck using appropriate straps and tensioning
devices. Be sure you secure to the deck only and not to
the outer trailer chassis. There are tie down locations
along both sides as well as the front rail. Since the trailer
“ride” can be bumpy and rough, secure the load so that it
does not shift while the trailer is being towed.
After securing the load, close and latch the gate or door of
the trailer, if equipped.
Ensure all personnel are clear and raise the deck to the
travel position by simply moving the "up/down" control
handle to the "up" position. Stop when the deck is all the
way up (continuing to hold the control will cause the fluid
to be pumped through the by-pass relief valve). At this
"up" position, the spring loaded travel latch will automati-
cally lock into place. Visually check that the travel latch
locks the deck into position.
