INFORMA
TION
The model 300-4 vibro is a high frequency vibratory
pile driver / extractor designed to drive and extract
sheet piles, pipe, timber piles and concrete piles,
caisson pipe and H, I and wide-flange beams.
The Model 300-4 operates in a frequency range
of 1250 to 1850 vibrations per minute to provide
maximum pile penetration rates in a wide variety of
soils. The unit has an eccentric moment of 5,300
inch-pounds.
The vibratory driver unit consists of two major
components
The vibration case which consists six eccentric
weights which rotate in a vertical plane to create
vibration. The eccentric weights are driven by a
hydraulic motors mounted on the vibration case.
The motors and four eccentrics are all gear
connected to maintain a proper synchronization.
The eccentric and motor shafts are mounted in
heavy-duty cylindrical roller bearings. Lubrication
is provided by a splash system activated by the
rotating eccentrics and gears.
A suppressor assembly is mounted to the top of the
vibration case, to isolate vibration from the crane
an permit pile extraction. A heavy outer suppressor
housing is connected to the vibration case by ten
rubber elastomer’s. The maximum line pull during
extraction is 133 tons.
A hydraulic clamp, bolted to the bottom of the
vibration case, transmits to the piling. The hydraulic
clamp contains two gripping jaws; one fixed and
one movable. A large hydraulic cylinder operates
the movable jaw with 125 tons (1,112kN) of force to
grip the pile. Clamping and un-clamping occurs in a
few seconds.
