PREVENTING ROPE OVERLAP
Do not allow the rope to become overlapped on the capstan during a pull.
A rope overlap will make it will impossible to continue or back out of the pull.
If the rope becomes overlapped, you will lose control of the pull — the rope will advance with no tailing force
and will not feed off of the capstan. The capstan will not allow you to reverse the direction of the rope, so you
cannot back out of an overlap.
Set up the puller properly. The rope ramp and tapered capstan are intended to prevent rope overlap. Refer to
the instructions in the "Operation" section of this manual.
Every wrap of the rope must remain in direct contact with the capstan. During the pull, take great care to
prevent the incoming rope from riding up and overlap-ping the next wrap. If an overlap begins to develop,
immediately relax the tailing force on the rope so that the rope can feed back toward the conduit or tray. When
the rope resumes its normal path, apply tailing force and continue the pull.
There is no suggested remedy for a rope overlap.
Do not allow the rope to overlap!
Summary of Cable Pulling Principles
• A cable pulling system consists of many components that work together to accomplish a pull.
• The cable puller is rated by its maximum pulling force; every other component is rated by its maximum rated
capacity. The maximum rated capacity of every component must meet or exceed the maximum pulling force
of the cable puller.
• The cable puller must overcome two types of resis-tance: gravity and friction. The puller's capstan, the
pulling rope, and the operator tailing the rope work together to produce pulling force.
• The cable puller exerts force on every component of the cable pulling system, including the anchoring
systems and the support structures.
• Energy is stored in a rope when the load causes the rope to stretch. Failure of the rope or any other
component can cause a sudden release of energy. Replace any rope that is worn or damaged.
• Carefully select the number or wraps of rope around the capstan before starting the pull.
• Control the pull by tailing the rope. Be familiar with the interaction of the rope and capstan.
• Do not allow a rope overlap to develop.
• Pull in a direction that will require the lowest amount of pulling force.
• Plan several shorter pulls rather than fewer longer pulls.
• Locate the puller as close to the end of the conduit as possible to minimize the amount of exposed rope
under tension.
• Place each component so that the pulling forces are used effectively.
• Select an anchoring system: adapter sheaves, which are preferred, or the floor mount.
• Verify that each component has the proper load rating.
• Inspect the structural supports. Verify that they have enough strength to withstand the maximum forces that
may be generated.
