Bronze sleeves are integrated on both
ends of the shaft for protection in in-
stances where the outer race of the bear-
ing could potentially turn on the shaft.
This reduces unnecessary downtime and
only requires the sleeve to be replaced,
according to McLanahan. All components
slide onto the shaft, allowing for easy re-
moval and installation. The straight shaft
features jacking bolts in the mechanism
tube that supports the shaft during chan-
geouts, eliminating the need for a crane
and thus improving safety while minimiz-
ing downtime.
The MAX line features labyrinth seals
to prevent oil contamination, eliminating
the need for a standard breather that
could plug and fail. Other design ele-
ments include independent cross mem-
bers that facilitate replacement of just
the worn tubes — not the complete deck
frame — increasing uptime and lower-
ing downtime. The standard motor base
features jacking screws to make belt
tensioning easier, and a conventional
pivoting motor base can also be provid-
ed. A Quick Change Spring Kit allows for
removal of the spring pack with only min-
imal vertical clearance without need of
an overhead crane.
Upgrades to existing screen designs
can also play a major role in improving
machine efficiency. For example, Ha-
ver & Boecker recently announced an
upgrade to its F-Class vibrating screen
system, which is claimed to cut service
downtime by 50%. According to the
company, its new split-bucket mount-
ing system, featured in all-new F-Class
vibrating screens, provides easy access
to critical components, such as rubber
McLanahan's MAX screens offer design features aimed at improving screen longevity and streamlining routine
maintenance procedures.
