CAUTION! Do not allow the weight of the machine to
rest on the carriage or the paving rollers. Damage to
the carriage or the paving rollers could result.
TOWING THE MACHINE
A Towing Hitch and a Transportation Dolly are accessories that are
available from the factory.
WARNING! The recommended maximum towing
length is 36 feet. The recommended towing speed,
on a smooth surface, is 40 MPH.
The transport system will be placed under the drive end of the
machine. Move the carriage toward the drive end to obtain a good cen-
ter of gravity of the machine. Now clamp transport system to machine
with clamps. Remove carriage when traveling long distances. If mov-
ing the machine on the job site the carriage can be left on the frame
track. Make sure that the carriage is secured and can’t move during
transport. Do not allow the carriage roller to rest on the carriage rail
while transporting. This will prevent the carriage rail
from being damaged.
30 inches). The screed chairs should not interfere with support studs.
The rails and chairs should be double checked after the positioning of
the machine.
When the machine is riding on bridge girders you will need to fabricate
a screed chair stand that will normally be epoxied or welded to a bridge
deck beam. It is also recommended that you tie the vertical tube to the
rebar mats. The top of the vertical tube should be below finished grade.
The screed rail needs to be adjusted to conform to the longitudinal
profile. This can be accomplished many different ways. You can use
an instrument to measure from quarter points on the deck to the top of
the screed rail using a level and rule; then pulling a stringline between
the two points or measuring from the grade line on the form to the top
of the screed rail.
SCREED RAIL AND PAVING FORMS
The screed rail and paving form setup is as important to a successful
operation as the machine itself. The setup of these two items is what
determines the longitudinal profile of your bridge deck or slab. There
are two screed rail setups for bridges. Normally, the specifications in
your area will dictate if the paving machine will ride on the forms or on
the bridge girders themselves.
When the machine is riding on forms the first area to look at is the type
and spacing of the overhang brackets. Consult with the factory about
your machine load weight. After the machine loads have been deter-
mined refer to the manufacturer’s specifications of the overhang
brackets for spacing of the brackets. Screed rail must be accurate and
conform to the grade required. ACP recommends 2 inch schedule 80
black pipe with an insert at one end to connect two sections. The
adjustable screed chairs should be spaced 24 inches apart (maximum

Remember this is just an initial setup. After the machine has been set
on the deck it will need to run up and down the screed rail to take out
any timber crunch or settling of the form work. Then another check of
the form must be performed.
