3-4 LeeBoy 8515E Conveyor Paver
Component Location
AugersAugers
Right and left augers
rotate to move material
from the conveyors to the
screed. The auger can
be manually controlled
at the operator platform
or by a screed operator
on the screed using a
remote screed control
box.
ScreedScreed
The screed is the last component that contacts the
paving material. Asphalt material is fed from the hopper
conveyor through the augers to the screed.
The LeeBoy 8515E Conveyor Paver is equipped with the
Legend® screed system that is electrically heated. The
optional Heavy Duty HD815 screed is also available. The
main screed has hydraulically-controlled extensions on
each side that extend and retract to allow paving widths
from 8 - 15 feet. Hydraulically-driven dual vibrators
mounted on the main screed frame increase paving
material compaction. The screed can be locked in the
raised position for travel, service and overnight parking
for additional stability.
The optional HD815 screed features heavy-duty ight
screws, heavy-duty crown and valley mechanism and
3-Adjuster AOA (Angle of Attack) with vertical height
adjustment for even more screed control.
Hydraulic SystemHydraulic System
The hydraulic system includes hydraulic pumps, motor
and cylinders that work together for optimum machine
component control. Valves regulate the directional,
pressure and uid ow throughout the hydraulic system.
The LeeBoy 8515E model is now equipped with
additional hydraulic oil cooling components for
smoother operation. Hydraulic test ports add ease and
convenience for checking pressure for the paver’s main
functions.
Electrical SystemElectrical System
The battery produces 12 volts DC and maintains 1,125
cold cranking amperes (CCA). An engine-mounted
alternator with a minimum of 60 amperes charging
capacity keeps the battery charged during normal
operation.
Heating controls provide the necessary connection and
control of the output power from the generator to the
heating elements. Each element is sized to t properly
in your screed, and provide sufcient power to heat
your screed plate to a temperature so asphalt material
will not drag or stick to the lower surface of the screed
plate. The heating control is mounted near the middle of
the main screed and is easily accessible to the screed
operator when a heating cycle is required.
The auger can also be controlled automatically using
the auger sonic sensor system. The sensor is mounted
on the screed endgates and used to monitor and control
the pile height of material at the discharge end of the
augers.
Hopper and ConveyorsHopper and Conveyors
Hydraulic power raises and lowers the hopper wings.
The hopper wings can also be locked into place in
the closed position for transport. When fully open, the
hopper can hold a payload up to 7.5 tons.
Material in the hopper is moved toward the back of the
paver to the screed by conveyors. Its wide, automatic
conveyors with a wide hopper design delivers asphalt
more evenly and efciently to produce a smooth asphalt
mat.
The conveyor bed can be lifted hydraulically, allowing
easy access to the paver undercarriage and tracks for
service and cleaning.
