Condux WDR505 Underground Pulling Trailer - Manual (Page 10)

Operating Procedures
It is essential that the Underground Pulling Trailer be properly set up before operation.
Using the following procedure will allow the unit to be set up in a short period of time
and yield optimum performance.
A. POSITIONING THE TRAILER & LOWER BOOM
Position the WDR 505 Puller within an approximate boom arm reach of the
manhole or duct bank. After trailer is positioned, lower boom arm.
NOTE: It may be necessary to payout a small amount of winch line (releasing it
from the boom) first to allow the boom to be lowered. If so please refer to Steps
C and D before proceeding.
Remove the traveling pin and carefully lower the boom to the position desired for
pulling operations (Figure 2). Once in position lock the boom in place with the pin
(Figure 3).
Now that the boom is in place, minor adjustments in the puller’s position can be
made if necessary for optimum working alignment.
B. STABILIzE TRAILER
After the WDR 505 is properly positioned, place wheel chocks to prevent trailer
movement.
NOTE: The trailer may be disconnected
from the tow vehicle or left connected
depending on specific site conditions.
After placing wheel chocks, stabilize the
trailer using three of the five supplied
adjustable leveling jacks. Place three
jacks in the jack mount locations on the
trailer. Raise and lower jacks by
rotating crank handle (Figure 4). Place
two jacks on the boom arm and adjust
jacks until the boom arm is level to the
ground (Figure 5).
