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 36" 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
12 3 /4 " over the spiral.
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 drum pulley (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 can-
not 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 and most mod-
ern 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 144" face
width.
