SECTION 2 - TRAILER OPERATION
2-4 – Triple-L-Trailer – 3121224
2.2 TRAILER FEATURES
1. Rails (Not Shown) - These surround the front and
sides of the deck and provide a means to aid in the
proper placement of cargo.
2. Storage - This compartment is used to secure the
owners manual, tools and other items.
3. Actuator - A device on the tongue of the trailer that
activates the optional hydraulic (surge) brake sys-
tem.
4. Coupler - A device on the tongue of the trailer that
connects to the hitch on the tow vehicle.
5. Safety Chains - If the coupler connection comes
loose, the safety chains can keep the trailer attached
to the tow vehicle. With properly rigged safety
chains, it is possible to keep the tongue of the trailer
from digging into the road pavement, even if the
coupler-to-hitch connection comes apart.
6. Tongue Jack - A device on the trailer that is used to
raise and lower the coupler to aid in coupling and
uncoupling the trailer. The jack is sometimes called
the “landing gear.”
7. Motor/Pump Battery - This compartment holds the
motor/pump and battery. The battery provides the
electrical power for raising and lowering the trailer
deck and the power for the electrically operated
breakaway brake system. The pump/motor provides
hydraulic fluid to the cylinder that raises the deck
into place for transport.
8. Up/down Control - The control lever used to activate
the hydraulic system to lower or elevate the deck.
9. Travel Latch - A mechanism that prevents the deck
from lowering to the ground unintentionally.
10. Identification Plate - This placard contains the Vehi-
cle Identification Number (VIN) and weight ratings
for the trailer.
11. Deck Bearing (Not Shown) - This component is
attached to the chassis and guides the bearing
channel when the trailer deck is being raised or low-
ered.
12. Bearing Channel - This component is part of the
trailer deck and rides on the deck bearing when the
deck is being raised or lowered.
13. Chassis - This is the structural frame work of the
trailer.
14. Deck - This is the surface where cargo is placed for
transport. It can be lowered for loading and raised
for transport.
15. Serial Number - This is a 17 digit number, also
referred to as the Vehicle Identification Number
(VIN), that can be found on the identification plate
and stamped on the frame of the trailer.
16. Suspension - The system that allows the trailer
wheels to absorb bumps in the travel surface.
17. Trailer Lighting (and braking) connector (not shown)
- A device that connects electrical power from the
tow vehicle to the trailer. Electricity is used to turn on
brake lights, running lights, and turn signals as
required. In addition, if you trailer has a separate
braking system, the electrical connector will also
supply power to the brakes from the tow vehicle.
18. Breakaway Cable - If the coupler connection comes
loose, the breakaway cable can actuate emergency
electrical brakes on the trailer. The breakaway cable
must be rigged to the tow vehicle with appropriate
slack that will activate the brakes if the coupler con-
nection comes loose.
19. Hitch (Not Shown) - A device on the tow vehicle that
supports the weight of the trailer tongue and pulls
the trailer. The coupler attaches to the hitch.
20. Descent Alarm - An alarm on the trailer that sounds
anytime the trailer is lowered.
21. Spare Tire (accessory) - A spare tire is mounted on
the side of the trailer.
DO NOT MOVE THE TRAILER UNTIL THE COUPLER IS SECURED
AND LOCKED TO HITCH, THE SAFETY CHAINS ARE SECURED
TO THE TOW VEHICLE AND THE TRAILER JACK(S) ARE FULLY
RETRACTED.
DO NOT TOW THE TRAILER ON THE ROAD UNTIL THE TIRES
AND WHEELS ARE CHECKED, THE TRAILER BRAKES ARE
CHECKED, THE BREAKAWAY CABLE IS CONNECTED TO THE
TOW VEHICLE, THE LOAD IS SECURED TO THE TRAILER AND
THE TRAILER LIGHTS ARE CONNECTED AND CHECKED.
