USE The Models CD-22 and CD-28 can be driven mechanically, hydromechanically
or hydraulically. Both winches have been primarily designed for placing under-
ground communication cable or electrical conductor. However, they can be used
for most applications where a long, continuous pull is required.
Mechanically - for mobile mounting, using the truck engine as the prime source of
power, through a split shaft or side mount power take-off and silent chain drive to
the winch input shaft.
Hydromechanically - for mobile mounting, using the truck engine as the prime
source of power, through a split shaft or side mount power take-off coupled to a
hydraulic pump, driving a hydraulic motor integrally mounted to the mechanically
shifted three speed transmission and silent chain drive to the winch input shaft.
Hydraulically - for mobile mounting, using the truck engine as the prime source of
power, through a split shaft or side mount power take-off, coupled to a hydraulic ;
pump, driving a three speed hydraulic motor and silent chain drive to the winch
input shaft.
Stationary mounted units can also be driven mechanically, hydromechanically or
hydraulically. The prime source of power can vary.
HYDRAULIC
REQUIRMENT Hydromechanical - to obtain the maximum rated pull and line speed, using the
three speed transmission model 240-584, the system should have an operating pres-
sure of 2,000 psi and a flow of 55 GPM. The pressure relief should be set at 2,200
psi.
Hydraulic - to obtain the maximum rated pull and line speed, using the three speed
transmission Model 230-1600, the system should have an operating pressure of
2,000 psi and a flow of 30 GPM. The pressure relief should be set at 2,100 psi.
Suction line hoses are 1" diameter minimum; return line hoses are IV" diameter.
The recommended hydraulic oil reservoir capacity for the Model 240-584 three
speed transmission is eighty gallons; for the Model 230-1600, sixty gallons.
The suction line is fitted with a 100 mesh strainer; the return line is fitted with a 10
micron by-pass type filter.
For additional details and information concerning the Model 240-584 three speed
transmission, see drawings 15669-1 and 15669-2; for Model 230-1600, see draw-
ings 230-1600-1 and 230-1600-2.
INSTALLATION For mobile applications, the winch is normally mounted behind the chassis cab in
the forward section of the body load area, directly to the chassis frame or sub-
frame. Two standard cast steel mounting brackets are furnished with each winch.
