I. GENERAL DESCRIPTION
B. VIBRATOR
The vibrator consists of two major components; The vibration case and the vibration
suppressor. The vibration case contains four eccentric weights which rotate in a vertical
plane to create vibration. The eccentric weights are driven by two hydraulic motors. The
vibrationsuppressorcontains 16 rubber elastomers (20or24optional)toisolate 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. Five types of hydraulic clamps are
available for the Model 44 vibrator. The Model 126 universal clamp will drive and extract
most types of sheet piling, 14” (355mm) H-beams, and wide flange beams. The Model
127 Z-pile clamp is designed to drive and extract single Z-sheets and can also be used
on Z-pile doubles. The Model 80 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 15” (381mm)ID to
136” (3454mm)OD. The Model 25 & 50 wood pile clamps are designed to drive and extract
wood piles from 8” (203mm) OD to 18” (457mm)OD. The model 165 concrete pile clamp
will drive and extract square concrete piles from 18” (457mm) to 24” (610mm).
Consult J&M in your area for any other clamp questions regarding
other than what is stated herein.
D. POWER UNIT
The Model 44 vibrator is powered by the J&M Model 580 Power pack. The 580 power pack
ispoweredbyaCaterpillar C-15 diesel engine. The engine develops 580 gross horsepower
(433kW) at 2100 RPM, and is mounted on a tubular sub-base which serves as a fuel tank.

I. GENERAL DESCRIPTION
F. CONTROL PENDANT
The vibrator is operated by a hand-held control pendant. The control pendant has three,
two-wayswitches(one with a light) and one push button. Oneswitch(SLOW-FAST) raises
and lowers the diesel engine speed. The second switch (REVERSE-FORWARD) starts
and stops the vibrator. The other switch (OPEN-CLOSE) operates the hydraulic clamp.
The light indicates that adequate clamping pressure exists for vibration to begin. The (red
mushroom) push button (EMERGENCY STOP) shuts down the diesel engine instantly, in
the event of an emergency. Note: Controls are duplicated on the control panel in case the
pendant is damaged. (See pg. III-5, Section E-e)

II. PREPARATION FOR OPERATION
C. RIGGING OF VIBRATOR
Asteel wire rope sling must be connected to the lifting pin of the vibration suppressor. The
required strength of this sling depends on the capacity of the crane and the work to be
carried out. A safety factor of five is recommended. Several turns of a smaller diameter
cable will usually last longer than one turn of a larger diameter cable.
All rigging of either the hydraulic power unit or vibrator must be
done in accordance with standard rigging guide lines set forth
in ASTM standards; J&M does not assume responsibility for
incorrect rigging or proceedures.
D. CONNECTION OF HYDRAULIC CLAMP
The vibrator is usually shipped with the hydraulic clamp already attached.
If the clamp is not attached, it will be necessary to attach it to the bottom of the vibrator.
Orient the clamp to the vibrator with the clamp cylinder end (movable jaw) at the same end
of the vibrator as the hose chute is mounted. All eight (1.5-6UNC x 5.00) bolts must be in
place and torqued to approximately 2800 ft-lbs.
For caisson work, the caisson beam must be attached to the bottom of the vibrator and
tightened as above. Then slide the clamps into position on the caisson beam.

II. PREPARATION FOR OPERATION
E. CONNECTION OF HYDRAULIC HOSES
1. Connection of hoses at power unit.
a. The vibrator and hydraulic clamp are connected to the power unit by five hydraulic
hoses (Fig. 1) on the previous page.
The power unit must be shut down during connection of the
hydraulic hoses.
b. The hoses connect to the power unit with quick-disconnect couplers. Hose couplers are
arranged to insure correct connections at the power unit. See the diagram (Fig. 1) for
correct hose connection.
c. Clean couplers with a lint-free cloth before making connections.
Do not use engine starting fluid to clean quick disconnects,
this will damage the seals and result in an oil leak.
d. Make sure that the couplers are fully run up, and hand tightened only, do not use
wrenches to over tighten.
2. Connection of hoses at vibrator.
a. The vibrator is usually shipped with the hoses attached to the vibrator. If the hoses have
been shipped separately, they must be connected in the field. Fig. 1 shows the correct
arrangement of the five hoses connecting the power unit to the vibrator.
Starting the vibrator with the hoses reversed will result in low
power or possible ruptured hoses.
b. The vibrator is usually shipped with the hydraulic clamp and hoses attached. If the
clamp has been shipped separately, the two hoses connecting the clamp to the vibrator
must be connected. (Fig. 2) shows the correct arrangement of these hoses.
Forcaisson clamps,fourhosesmust beconnected. Thetwoconnections ontheopposite
end of the vibrator are reversed from the positions shown in Fig. 2. Both ends of the
vibrator are stamped with an “O” and a “C” to insure correct connetion. The clamp
connections are also stamped with an “O” and a “C”.
