Operation
Description Of Operation
The LeeBoy Model 8616 Conveyor Paver has
hydrostatic driven tracks that propel the paver. The
hydrostatic assist feature can be engaged by the
operator using a friction-controlled joystick. Two
friction-held joysticks control the speed of the paver in
conjunction with a maximum speed setting. Ramping for
acceleration and deceleration are proportional to the
movement of the joysticks.
The direction of the paver is controlled by using the dual
joysticks. Multiple switches and dials positioned on the
paver allow the operators to control all paving functions.
The operator can operate the paver from one of two
identical control stations. Left and right sides are
determined by sitting in the normal operation position
facing straight ahead in the forward direction of travel.
Propel System
The propel system utilizes a dual path proportional
system to control the tracks. In low speed, the inside
track will be allowed to counter-rotate. In high speed, the
inside track will not counter rotate.
Steering
Steering of the tracks is controlled by a hydraulic
proportional pump. The amount of steering is controlled
by the amount of joystick movement and the speed of
the paver. As the paver speed increases, the amount of
steering will be reduced.
Throttle
Engine RPM is set manually by using the throttle up
and throttle down buttons located on the ENGINE
and PAVER screens of the display unit. Engine RPM
automatically increases to 1800 RPM when conveyor
and/or augers are turned on. When generator is turned
on, engine RPM automatically goes to 1400 RPM unless
augers and/or conveyors are on, then engine will remain
at 1800 RPM. While in motion, if the joysticks are set to
neutral position for 10 seconds, the engine will go to idle.
When the joysticks are taken out of neutral, the engine
immediately returns to last set RPM.
Operating Controls
