MODEL 66-80 VIBRATORY DRIVER/EXTRACTOR
I. GENERAL DESCRIPTION
B. VIBRATOR
The vibrator consists of two major components; The vibration case and the
vibration suppressor. The vibration case contains six eccentric weights which
rotate in a vertical plane to create vibration. The eccentric weights are driven by
two hydraulic motors. The vibration suppressor contains a minimum of 24 rubber
elastomers to isolate the vibration case from the crane line. The suppressor is
designed for a maximum line pull of 80 tons (712kN) during extraction.
C. HYDRAULIC CLAMP
The hydraulic clamp attaches the vibrator to the pile. Four types of hydraulic
clamps are available for the Model 66 vibrator. The Model 196 universal clamp
will drive and extract most types of sheet piling, 14" (355mm) H-beams, and wide
flange beams. The Model 122 caisson clamps are used in pairs with either the 7-
foot (2.13m) or 11-foot (3.35m) caisson beam to drive and extract pipe from
22.25" (565mm)ID to 129.25" (3283mm)OD. The Model 50 wood pile clamp is
designed to drive and extract wood piles from 10” (254mm) OD to 18” (457mm)
OD. The model 165 concrete pile clamp will extract square concrete piles from
18” (457mm) to 24” (610mm).
D. POWER UNIT
The Model 66 vibrator is powered by the J&M Model 950 power pack. The 950
power pack is powered by a Caterpillar 3412DIT diesel engine. The engine
develops 800 horsepower (597kW) at 1900 RPM, and is mounted on a tubular
sub-base which serves as a fuel tank. The Power Unit and Vibrator are operated
from the control panel or remote control pendant. Hydraulic oil is stored in the
reservoir. Oil cooling is accomplished by a air to oil heat exchanger mounted in
front of the engine radiator. All of the above components are contained in a sheet
metal enclosure, with lockable doors, and a central lifting bale. Five hydraulic
pumps are mounted to the engine via a multi-output gear box.
E. HOSES
Three hydraulic hoses, 150 feet (45.7m) in length, connect the power unit to the
hydraulic motors on the vibrator. Two other hydraulic hoses run from the power
unit to the hydraulic clamp.
F.REMOTE-CONTROL PENDANT
The vibrator is operated by the hand-held remote control pendant. The pendant
has 1 palm button, 2 switches and 2 push buttons, 1 with a light. The red palm
button (EMERGENCY STOP) shuts down diesel engine instantly in the event of an
emergency. The (OPEN CLOSE) switch opens and closes the hydraulic clamp.
The light in the (START) button indicates that adequate clamping pressure exists.
The (START) button starts vibration. The (STOP) button stops vibration. The
(THROTTLE) switch raises and lowers the diesel engine speed. Note: Controls
are duplicated on the control panel for use if the pendant becomes damaged.
