Gardner Bender CP2000 - 2000 lb Cable Puller - Manual (Page 4)

WARNING: The rope on the capstan can crush your
hand during operation. Do not allow the rope to wrap
around any part of your body. Keep loose clothing,
hands and body away from moving parts.
During normal pulling operations, the cable resistance will
constantly change. This will require the operator to change
his tailing force in response. The operator can relax this force
completely and stop the pull at any time. The capstan
requires some tailing force before it will pull. This assures
complete operator control. Do not continue to hold the rope
on the capstan if it starts to slip. Rope wear from friction and
heat will result. This could cause the rope to break. Turn off the
motor and secure the rope.
On a vertical pull, resistance to the force of gravity will tend to
reverse the pull. The weight of the cable will increase as the
vertical height of the pull increases due to the added cable
length. Resistance created by friction will require more pulling
force, but will not reverse the pull.
DANGER: Never stand directly under a vertical pull.
Using Sheaves
Sheaves are used to change the direction of pull and reduce
the friction load. When you install a sheave, make sure the
sheave support can withstand the total force. The force on
the sheave can be as high as double the pulling force. See
Figure 5.
WARNING: All pulling system components must be
rated to withstand the maximum pull forces.
Pulling Rope
WARNING: Only use rope that is rated for the
pulling force required. Check the rope often for damage.
Damaged rope can break and cause eye or other
bodily injury.
The pulling rope is a very important part of the cable pulling
system. Use a rope with a low stretch factor that has a load
rating greater than the total estimated pulling forces expected.
WARNING: Never stand directly behind the path of a
pulling rope. Keep exposed part of pulling rope as short
as possible. A broken pulling rope can whip with
extreme force.
7.0 ASSEMBLY
1. Extend the CP2000:
Remove the clevis pin from the foot. Raise the leg
extension to release the puller arm from the base. See
Figure 7. Reinstall the clevis pin in the foot to secure the
foot to the leg extension. Rotate the puller arm to a parallel
position. Set the arm extension on an available support.
The arm length can be adjusted by removing the clevis pin.
Slide the arm extension in or out as needed and reinstall
the clevis pin.
2. Install the power drive.
The CP2000 requires a power drive (Figure 8) to supply
the pulling force. The CP2000 puller is designed to use a
portable pipe threader power drive such as the Mini-
Collins
® or Rigid™. Other power drives that you may
already have may also be used. Before you install the
power drive on the CP2000 you must depress and secure
the power switch with the clamp provided (Figure 9).
