REINFORCED DRUM-WITHIN-A-DRUM
DESIGN SAVESYOU A TON ONYOUR
CONVEYOR SYSTEM!
The most sophisticated conveyor system in the
world isn’t worth a dime when it’s down. And yet, the
obvious trend towards larger, more complex, more
demanding systems cal ls for improvements in
technology and engineering throughout the entire
system...and the application of these improvements.
This is especially true in the area of conveyor
pulleys. For example, in recent years, modern, high
tonnage conveyor systems and the increased use of
belting reinforced with steel cables have created forces
not previously considered in present pulley design.The
result? Pulley failure. Consequently, there has been
sufficient cause for engineers to design to more
conservative stress and deflection levels. In fact, until
more accurate field testing and feedback from existing
applications can be accumulated, the most practical
way to avoid premature failures is by designing to
these lower stress and deflection levels.
Double Drum™ Pulleys
TheVANGORP® Double Drum™Pulley is in a class
by itself. It is engineered to meet these demanding
loading conditions and has established an impressive
performance rating from many satisfied customers. In
fact, with hundreds of Double Drum™Pulleys presently
in service all over the world, it has proven itself in both
design and performance. The reason? A unique drum-
within-a-drum design that decreases end disc slope and
minimizes stress at both rim end and hub end disc
locations. A pulley design that decreases shaft deflection
between hubs and prevents pre-stressing the end discs
when assembling taper type hubs. A pulley matched to
your conveyor’s maximum capacity; then built by a
precision-engineered, “two-rim-half” process that many
have never considered nor taken time to imitate.
In many applications end discs can be held to a
much more practical thickness which actually results in
a lighter and more economical pulley than those with
heavier end discs.
The VAN GORP® Double Drum™ Pulley ...saves
you a ton on your conveyor system. In fact, we
guarantee it...for two full years.
