Tow Vehicle Recommendations and Requirements
D
Graco recommends a tow vehicle wheelbase of at least 130 in. (305 cm) for normal highway use.
D
The tow vehicle must have 1/2 ton or greater carrying capacity.
D
The tow vehicle must have a minimum payload capacity of 1400 lb (635 kg).
NOTE:
This minimum payload capacity is for a RoadLazer trailer with a full bead tank only. The payload
capacity must be increased by the weight of striping paint, additional glass beads, cargo in the truck, and
passengers other than the driver. See Fig. 1.
D
The tow hitch must have a minimum rated capacity of 750 lb (340 kg) TW, 7500 lb (3402 kg) GTW.
NOTE:
This is the minimum rated capacity as defined by SAE Standard J684 Class 4 hitch requirements for a
Gross Trailer Weight (GTW) of 7500 lb (3402 kg). Recommended hitch manufacturers available upon request.
Calculating Tow Vehicle Payload Capacity
Use the sample calculation below to determine the minimum payload capacity requirement for
the RoadLazer tow vehicle:
RoadLazer with full tank of beads
1400 lb
Striping paint
(15 lb per gal.)
{
gal. x 15
=
lb
Additional glass beads (50 lb per bag)
{
bags x 50
=
lb
Tow vehicle minimum payload capacity: 1400 lb + (
lb) + (
lb) =
lb
{
Calculation assumes waterborne traffic paint and 50 lb bags of glass beads. Actual numbers could
vary, depending on the paint or beads used.
Fig. 1
Example:
One 55-gallon drum of waterborne striping paint and 2 extra bags of beads:
Tow vehicle minimum payload capacity: 1400 lb + (15 x 55) + (50 x 2) = 2325 lb
+
The tow vehicle must have the following additional equipment:
D
Warning lights and/or sign board per federal, state,
and local regulations. Reference
Part IV of the
Manual on Uniform Traffic Control Devices
(MUTCD)
by the U.S. Department of
Transportation, Federal Highway Administration, for
federal regulations.
D
Securing device for paint supply containers that can
be sealed during transport.
D
Standard trailer light connector.
D
DRAW-TITE
R
Class IV Ultra Frame Hitch with two
Graco clamp-on receivers that are 32 in. (81 cm) on
