LeeBoy 8608 - Hopper Wings

Hopper WingsHopper Wings
The hopper wings are hydraulically opened so the
hopper can be lled with paving material. The 8608
paver features a 9-ton, rounded design to reduce cold
material build-up while rear hopper wing wipers help
prevent spillage. (Figure 4-55)
Material in the hopper is moved toward the back of the
paver to the screed by conveyors. The narrow, auto-
matic conveyors with a wide hopper design delivers
asphalt more evenly and efciently to produce a smooth
asphalt mat. The hopper’s rounded design reduces
cold material build-up while rear hopper wing wipers
help prevent spillage.
The operator can also extend and retract each hopper
wing individually. This feature gives you the ability to
pave very close to walls, fences, road barriers, buildings
or other obstacles with ease.
DO NOT retract the hopper wings until
the material truck has moved completely away from
the paver or if the hopper is full of asphalt. NEVER
raise the conveyor bed with asphalt in the hopper.
Ensure no people, equipment or other
obstacles are in or near the hopper when raising or
lowering the hopper wings to prevent injury or
damage to the paver.
Ensure the hopper cylinder valves are
unlocked before extending or retracting the hopper
wings.
