MODEL 44-50
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 four eccentric weights which rotate in a vertical
plane to create vibration. The eccentric weights are driven by two hydraulic motors. The
vibration suppressor contains 16 rubber elastomers (20 or 24 optional) 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. 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 fl ange 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).
D. POWER UNIT
The Model 44 vibrator is powered by the J&M Model 580 Power pack. The 580 power pack
is powered by a Caterpillar 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.
E. HOSES
A hydraulic hose bundle (multiple hoses) connects the hydraulic power unit to the vibrator unit.
