2.3 GENERAL
Trailer VIN Information
The Trailer Features figure shows the location of the Trailer
Identification Plate on your trailer.
The Trailer Identification Plate contains the following criti-
cal safety information for the use of your trailer.
a.
GVWR:
The maximum allowable gross weight of
the trailer and its contents. The gross weight of
the trailer includes the weight of the trailer and
all of the items within it (such as cargo, water,
food and other supplies). GVWR is sometimes
referred to as GTWR (Gross Trailer Weight Rat-
ing), or MGTW (Maximum Gross Trailer Weight).
GVWR, GTWR and MGTW are all the same rat-
ing.
b. GAWR:
The maximum gross weight that an axle
can support. The sum total of the GAWR for all
trailer axles may be less than the GVWR for the
trailer, because some of the trailer load is to be
carried by the tow vehicle, rather than by the
trailer axle(s). The total weight of the cargo and
trailer must not exceed the GVWR, and the load
on an axle must not exceed its GAWR.
c.
RIMS
- Specification of rims equipped on the
trailer.
d.
TIRES -
Size and load rating of tires equipped
on the trailer.
e.
INFLC:
The tire pressure (Pounds per Square
Inch) measured when Cold.
f.
VIN:
The Vehicle Identification Number is a 17
digit serial number located on the trailer identifi-
cation plate.
g.
SERIAL NO
- JLG manufacturing number. Use
this number when conducting business with
JLG.
2.4 COUPLER
A coupler connects to a ball that is located on or under the
rear bumper of tow vehicle. This system of coupling a
trailer to a tow vehicle is sometimes referred to as
“bumper pull.”
The trailer is equipped with a ball hitch coupler that is suit-
able for the size and weight of the trailer. Your trailer may
be equipped with a 2" or a 2-5/16" coupler. The load rating
of the coupler and the necessary ball size are listed on the
trailer tongue. Do not change the coupler to a smaller
size. You must provide a hitch and ball for your tow vehi-
cle, where the load rating of the hitch and ball is equal to
or greater than that of your trailer. The ball size must be
the same as the coupler size. If the hitch ball is too small,
too large, is underrated, is loose or is worn, the trailer can
come loose from the tow vehicle, and may cause death or
serious injury.
THE TOW VEHICLE, HITCH AND BALL MUST HAVE A RATED
TO W I N G CA P A C I T Y E Q U AL T O O R G RE AT E R TH A N TH E
TRAILER GVWR (GROSS VEHICLE WEIGHT RATING).
IT IS ESSENTIAL THAT THE HITCH BALL BE OF THE SAME SIZE
AS THE COUPLER.
2.5 BRAKES
Governmental regulations may contain various brake
requirements. Some of these regulations may require the
use of electric brakes only or require brakes on all wheels
of a tandem axle trailer.
NOTE:
It is the responsibility of the owner to meet the
requirements of all governmental regulations in his
area.
Electric Brakes (Option)
The electric brakes on this trailer are similar to the drum
brakes on an automobile. The basic difference is that the
automotive brakes are actuated by hydraulic pressure
while electric trailer brakes are actuated by an electro-
magnet. The brakes are applied by a brake controller
installed on the tow vehicle.
Hydraulic Brakes - Surge Brakes (Option)
The hydraulic brakes (surge brakes) on the trailer are
actuated by a master cylinder. The hydraulic fluid from the
master cylinder is used to actuate the hydraulic wheel cyl-
inder which, in turn applies force against the brake shoes
and drum. A surge tongue actuator is required for a trailer
with hydraulic brakes.
