SPIRAL WING
The spiral wing pulley is formed by a pair of flat steel
bars helically wound towards one another with intervals
between the convolutions of each. Individual gussets
are welded continuously to each wing and the hub
forming a strong double-cone design.
Rotation of the pulley automatically starts the self-
cleaning action, discharging foreign material to the
side of the conveyor.
No more belt misalignment because the multi-wing
construction decreases the possibility of any material
build up between the belt and pulley.
AVAILABLE IN CROWN OR STRAIGHT FACE.
SIZES: 10" THRU 60" Diameters and 12" THRU 76"
Face.
NOTE: The finished diameter will be greater than the
specified diameter by twice the spiral bar thickness.
Example: A 12" diameter spiral wing will actually be

Spiral Wing
and Spiral Drum Pulleys
SPIRAL DRUM
The VAN GORP
®
Spiral Drum Pulley is formed by a pair
of vertical steel bars helically wound around a heavy-duty
reinforced drumpulley (H•D•R
®
) and towards one another
with intervals between the convolutions of each. This
unique design reduces the possibility of material build-
up between the belt and the pulley in applications where
self-cleaning wing type pulleys cannot be used.
Rotation of the pulley automatically starts the cleaning
action, discharging foreign material to the side of the
conveyor.
All pulleys are made with XT
®
, Tapered Bore or Q-D
®
Hubs, which permit the simplest, surest andmost modern
installation. Hubs are inset from the pulley end, and this
inset permits the bushing to be easily removed in small
confined spaces.
AVAILABLE IN CROWN OR STRAIGHT FACE.
SIZES: 12" THRU 44" Diameters up to 76" face width.
