Vibratory System
The pod-style vibratory system delivers superior compactive force while offering
serviceability advantages.
Pod-style weight housing is assembled
and sealed at the factory to ensure
cleanliness, longer bearing life and
easier field exchange or service.
Dual amplitude works efficiently in a
wider range of applications. Selection is
controlled from the operator’s station.
Vibratory frequency of 31.9 Hz (1914
vpm) for maximum compaction results.
Optional variable frequency control
allows frequency to be better matched
to varying job conditions.
Large heavy-duty bearings for the
eccentric weight shaft designed for high
compactive forces.
3 year/3000 hour vibratory bearing lube
service interval reduces maintenance.
Heavy-duty isolation mounts allow more
force to be transmitted to the ground and
less vibration to the drum yoke.
Proprietary Eccentric Weights
Reliable dual amplitude selection and innovative design ensure precise performance.
Positive amplitude selection is
accomplished when the steel shot is
repositioned inside the hollow eccentric
weight. Direction of weight shaft
rotation determines amplitude level.
Simplified control from the operator’s
station with a selection switch on the
operator’s console.
High reliability since there is no chance
of the high-strength spherical steel shot
wedging together. System reliability is
superior to swinging mechanical
weights and is also quieter during starts
and stops.
Long service life. No heavy weights to
slam together, no metal fragments to
contaminate the bearing lubrication
system.
