PREFACE
This manual was prepared to acquaint the owner, operator
and serviceman with the operation and maintenance of the
vibratory driver/extractor. We strongly suggest that this
manual be carefully studied before operating or undertaking any maintenance work
on the unit. It is not meant to be all inclusive as to content, and any questions and/
or doubt should be directed to J&M before proceeding with any operation or
maintenance.
This manual is organized into two major categories.
ThefirstcategoryisforOPERATINGINSTRUCTIONS of the unitandincludesaGENERAL
DESCRIPTION section, which presents a basic explanation of the driver/extractor
specifications. The MAINTENANCEANDADJUSTMENT section should be referred to for
all servicing of equipment. All machines and equipment require systematic, periodic
inspection and maintenance, if they are to perform satisfactorily.
The second category is for parts ordering and it includes both a PARTS LISTand a pictorial
drawing of the assembly. Refer to the ORDERING PARTS section of the PARTS LIST for
more specific procedures regarding parts ordering. Adherence of the listed procedures will
insure receipt of the required part(s) with the minimal amount of delay or error.

Refusal: Vibros: If the pile does not move one foot in 30 seconds of vibro operation at full speed. Resort to
a larger vibro. APE/J&M equipment may exceed the refusal driving criteria for short periods of time as may be needed
to penetrate hard soil layers or obstacles. In such cases, a heat gun is used to monitor the temperature of thebearings and
related components to prevent use of the machine beyond 210 degrees. ContactAPE/J&M or your local
APE/J&M distributor for special instructions when faced with refusal conditions.
Refusal: Diesels: Do not exceed 10 blows per inch or 120 blows per foot. In cases of setting of the pile it is
permitted to increase the blow count to 250 blows per foot, but only for one foot of driving penetration. Pile
inspectors should consult the APE factory for permission to exceed these limits. Failure to do so will void the
warranty. This standard specification is accepted by the DFI (Deep Foundations Institute) and the PDCA
(Pile ContractorsAssociation) and by all manufacturers of pile driving equipment.

INSTRUCTIONS
A. GENERAL
The J&M Model 44 is a low-frequency vibratory pile driver/extractor designed to drive and
extractsheet,pipe,timberandconcretepiles,caissonpipeandH,Iandwide-flangebeams.
TheModel44 operates in a frequency range of800to1600 vibrations per minute to provide
maximumpilepenetrationratesin a wide variety of soils. The unit has aneccentricmoment
of4400inch-pounds(50.7kg-M)andproduces a maximum amplitude of 1.20 inch (30 mm).
The vibratory driver unit consists of two major components. (1) The vibrator with attached
clamp and (2) the hydraulic power unit with control pendant.

INSTRUCTIONS
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.
The Power Unit and Vibrator are operated from the control panel or control pendant.
