Cable Pulling Principles
Pulling cable is a complex process. This section of the manual describes and explains four main topics of pulling cable:
- each cable pulling system component
- how these components work together
- forces that are generated
- procedures for the cable puller operator to follow
While reading through this section of the manual, look for components that are
shaded in the illustrations. The shading indicates components that are
associated with the text.
Greenlee strongly recommends that each member of the cable pulling crew review
this section of the manual before each cable pull.
Cable Pulling Systems
Pulling cable requires a system of components. At a minimum, a cable pulling
system will include a cable puller, a cable pulling rope, and connectors to
join the rope to the cable. Most systems will also include, but are not
limited to, a cable puller anchoring system, pulling sheaves, and sheave
anchoring systems.
The cable puller has a maximum amount of pulling force, which is the amount of
pulling tension that it develops. Every other component of the pulling system
has a maximum rated capacity, which is the amount of pulling tension that it
can withstand. The maximum rated capacity of every component must meet or
exceed the cable puller’s maximum pulling force. Pulling Theory
This section introduces the main ideas involved with pulling cable.
Pulling Resistance
The cable puller must overcome two types of resistance: gravity and friction.
Gravity constantly exerts its force on the vertical portions of the run. When
the pulling force is relaxed, gravity attempts to pull the cable downward.
Friction develops where the cable contacts the sheaves, conduit, and tray.
Friction resists any movement, forward or backward, and tends to hold the
cables in place.
To accomplish a cable pull, the cable pulling system must develop more force
than the combination of gravity and friction.
Generating Pulling Force
To generate pulling force, the capstan works as a force multiplier. The
operator exerts a small amount of force on the rope. The cable puller
multiplies this and generates the pulling force.
This pulling force is applied to the rope, connectors, and cable in order to
accomplish the pull. The direction of force is changed, where necessary, with
pulling sheaves.
Cable Pulling
Forces
This section provides detailed explanations and illustrations of the forces
that are generated during the cable pull.
These explanations are based on the concepts presented in the last section,
“Pulling Theory.”
At the Cable Puller Anchoring System
The cable puller will exert its maximum pulling force on cable puller’s
anchoring system. It is extremely important the anchoring system can withstand
this amount of force.
Refer to “Setup: Floor Mount” for proper setup or installation. At the Capstan
The capstan acts as a force multiplier. The operator exerts a small amount of
tension, or tailing force, on the rope; the capstan multiplies this force to
pull the cable.
The resultant force depends upon the number of times the rope is wrapped
around the capstan, as shown in the formula below.
Pulling Force = Tailing Force x e 0.0175µø
Where: e = the natural logarithm, or 2.7183
µ = the coefficient of friction between the rope and the capstan *
ø = the number of degrees of wrap of rope around the capstan
- The average value for the coefficient of friction when double-braided composite rope is pulled over a clean dry capstan is 0.125.
The following table is based on the formula above.
The input, or tailing force, is constant at 44.5 N (10 lb).
Increasing the number of wraps increases the pulling force.
Operator’s Tailing Force| Number of Wraps of Rope|
Approximate Pulling Force
---|---|---
44.5 N (10 lb)| 1| 93.4 N (21 lb)
2| 213.5 N (48 lb)
3| 474.9 N (106 lb)
4| 1043.8 N (233 lb)
5| 2293.7 N (512 lb)
6| 5048.9 N (1127 lb)
7| 11.1 kN (2478 lb)
This table shows how the capstan acts as a force multiplier. Because the coefficient of friction depends upon the condition of the rope and capstan, this formula cannot determine an exact amount of pulling force.
At the Pulling Rope
The product of a force (f) moving through a distance (d) is energy (f x d),
and may be measured in newtonmeters or foot-pounds. Energy is stored in a rope
when the rope is stretched.
This is similar to the way energy is stored in a rubber band when it is
stretched.
Failure of the rope or any other component of the pulling system can cause a
sudden uncontrolled release of the energy stored in the rope.
For example, a 100-meter nylon rope with a 50,000 newton average breaking
strength could stretch 40 meters and store 1,000,000 joules of energy. This is
enough energy to throw a 900-kilogram object, such as a small automobile, 113
meters into the air.
A similar double-braided composite rope could store approximately 300,000
joules of energy. This could throw the same object only 34 meters into the
air.
The double-braided composite rope stores much less energy and has much less
potential for injury if it were to break.
Double-braided composite rope is the only type of rope recommended for use
with the Ultra Tugger cable puller. Select a double-braided composite rope
with an average rated breaking strength of at least 143 kN (32,000 lb).
At the Connectors
The connectors will be subjected to the cable puller’s maximum pulling force.
Several types of rope connectors—clevises, swivels, and rope-to-swivel
connectors—are available. Follow the instructions provided with each to
provide a good connection.
Two types of wire connectors—wire grips and pulling grips—are available. The
wire grip uses a set screw to clamp onto the conductors of the cable. The
pulling grip consists of a wire mesh basket that slides over the cable and
grips the insulation.
When selecting a pulling grip, it is extremely important to select a grip of the correct (1) type, (2) size, and (3) maximum rated capacity.
- Select the correct type based on the descriptions of each type in the Greenlee catalog.
- Measure the circumference of the wire bundle. (To do this accurately, fasten a tie strap around the bundle. Cut off and discard the tail. Then cut the tie strap and measure its length.) Use the table provided to find the correct size.
- See the maximum rated capacities in the Greenlee catalog.

At the Sheaves
Sheaves are used to change the direction of the pull.
A change in direction creates a new resultant force that may be greater than
the cable puller’s maximum pulling force. This new resultant force exerts
itself on the sheaves, sheave anchoring system, and support structures
illustrated.
The resultant amount of force depends on the angle of the change in direction.
A brief table is provided here.
Refer to “Calculating the Hook Load” to determine the resultant force at any
angle.

Calculating the
Hook Load
One Attachment Point
To calculate the hook load exerted at one attachment point, use the Reference
Table and Formula 1. Formula 1:
R = 2 x T x SIN ((180 – θ) / 2)
R = the resultant force, or hook load; this force is exerted on the hook,
anchoring, and structural support
θ = the angle of change in rope direction
T = the tension exerted on the rope by the cable puller
Note: The total load on the support structure = R + the weight of the
sheave.
Two Attachment Points
To calculate the hook loads exerted at two attachment points, use the
Reference Table and Formulas 1, 2 and 3. R1 = resultant force on left hook, anchoring, and
support structure
R2 = resultant force on right hook, anchoring, and support structure
A = angle between the left mounting and the centerline of the two legs of the
rope
B = angle between the right mounting and the centerline of the two legs of the
rope
R = the resultant force, or hook load; this force is exerted on the hook,
anchoring, and structural support
θ = the angle of change in rope direction
T = the tension exerted on the rope by the cable puller
Notes: The total load on the left support structure = R1 + the weight of the
sheave.
The total load on the right support structure = R2 + the weight of the sheave.
Hook Load
Two variables interact with the sheave to produce a resultant (total) force,
or hook load. This load, represented by R in the formulas and illustrations,
is exerted on the hook, anchoring, and structural support.
Sheave Forces R = the resultant force, or hook load; this force is
exerted on the hook, anchoring, and structural support
θ = the angle of change in rope direction
T = the tension exerted on the rope by the cable puller

Some Hook Loads Illustrated
A straight rope exerts no load on the hook and structure.| A rope that makes a
120° angle exerts the total pulling force on the hook and structure.
---|---
A rope that makes a 150° angle exerts 1/2 of the pulling force on the hook and
structure.| A rope that makes a 90° angle exerts 1-1/2 times the pulling force
on the hook and structure.
Arope that makes a 135° angle exerts 3/4 of the pulling force on the hook and
structure.| A rope that makes a 0° angle exerts 2 times the pulling force on
the hook and structure.
Tailing the Rope
The rope must be pulled off of the capstan as the pull progresses. The rope
that has left the capstan is the “tail.” The process of pulling the rope off
of the capstan is called tailing the rope.
The resistance of the cable varies throughout the duration of the cable pull.
Changes in resistance are due to characteristics of the rope, changes in
conduit direction, and changes in the amount of friction. The “feel” of the
rope provides this information about the pull. This is called tactile
feedback. Adjust the tailing force as necessary to compensate for these
changes.
Control of the Pull
Decreasing the tailing force will decrease the pulling force, until the rope
slips on the capstan and the pull stops. This provides a high level of control
over the progress of the cable pull.
Do not allow the rope to slip on the capstan for more than a few moments. If
it becomes necessary to completely stop a pull, shut off the puller and
maintain enough tailing force to hold cable in place. Tie the rope off to hold
it in place. Use the rope tie-off to hold it in place.
Amount of Tailing Force
While the rope and cable are under tension, it is im-portant to maintain the
proper amount of tailing force.
Too little tailing force will allow the rope to slip on the capstan. This will
build up excessive heat and accelerate rope wear, increasing the possibility
of breaking the rope.
The proper amount of tailing force will stop the rope from slipping on the
capstan and produce a sufficient amount of pulling force to pull in the rope
and cable.
Too much tailing force is any amount more than is necessary to stop the rope
from slipping on the capstan.
Excessive tailing force will not increase the pulling force or pulling speed.
Number of Wraps of Rope around the Capstan
An experienced operator should choose the number times the rope is wrapped
around the capstan.
The proper number of wraps allows the operator to control the progress of the
pull with a comfortable amount of effort.
Using too few wraps requires a large tailing force to accomplish the pull.
Using too few wraps also makes the rope more likely to slip on the capstan.
This builds up heat and accelerates rope wear.
Using too many wraps causes the rope to grab the capstan tighter. This
accelerates rope wear, wastes power, and increases the possibility of a rope
overlap.
Using too many wraps also reduces tactile feedback, so you receive less
information about the pull. You cannot quickly relax the tailing force when
there are too many wraps.
If the rope becomes difficult to tail, add another wrap of rope. Turn off the
puller and release all of the tension in the rope. Add a wrap and resume
pulling. Be aware, however, that some pulls will require tension to hold the
cables in place. In these cases, do not attempt to release all of the tension
and add a wrap of rope. You will need to anticipate the number of wraps before
starting the pull.
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
overlapping 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.
Planning the Pull
- 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.
- Make sure area is clear of bystanders, etc.

Requires: A concrete floor with the following characteristics:
- fully cured structural-type concrete
- minimum compressive strength of 211 kg/cm (3000 psi)
- free of cracks, crumbling, or patchwork
WARNING
Follow all floor mounting instructions carefully.
- An improperly attached floor mount can come loose and strike nearby personnel.
- Do not attach the floor mount to masonry, brick, or cinder block. These materials will not hold the anchors securely.
Failure to observe this warning could result in severe injury or death.
-
Determine the best position for locating the floor
• mount. Locate the floor mount: on a flat section
• at least 152 mm (6″) from edge of concrete
• as close to the conduit as possible to reduce the amount of exposed rope under tension
• so that the pull rope will approach the puller’s capstan at a 90° (±5°) angle. -
Set the floor mount in the desired location. Use thefloor mount as a template to drill four ∅15.87 mm (5/8″) holes at least 152 mm (6″) deep.
Note: Use a ∅15.87 mm (5/8″) carbide-tipped masonry bit manufactured in accordance with ANSI standard B94.12-77. -
Vacuum the debris from the holes.
Installation
Greenlee recommends using Greenlee 35607 Wedge Anchors. If another type of
anchor is used, they must have an ICBO (International Conference of Building
Officials) allowable tension and shear rating of 10.7 kN (2400 lb) in 211
kg/cm2 (3000 psi) concrete.
-
Assemble the nut and washer to the anchor so the top of the nut is flush with the top of the anchor, as shown.
-
Insert the four anchors through the floor mount and into the holes in the floor.
-
Hammer the anchors in until the washer is in firm contact with the floor mount.
-
Expand the anchors by torquing the nuts to 122 to 128 Nm (90 to 95 ft-lb).
WARNING
If any of the four anchors spin before the minimum torque is achieved, abandon the location and start elsewhere. An improperly installed anchor can allow the puller to break loose.
Failure to observe this warning could result in severe injury or death. -
Have the installation checked by a qualified inspector.
Operation
-
Fish the rope through the conduit.
-
Set up the cable puller. Refer to “Typical Setups” illustrations and instructions in this manual.
WARNING
Set up the cable puller so that the rope will approach the capstan at an angle of 90° (±5°).
Angles outside of this range may cause the rope to overlap. -
Set the rope ramp as follows:
a. Wind the rope several times around the capstan. b. Pull the ramp away from the mounting plate and rotate it until the flat surface contacts the rope. c. Push the ramp toward the mounting plate and rotate it counterclockwise until it locks into place. -
Check the I/O switch on the puller to be sure it is OFF (O). Plug the puller into the receptacle of the standard force gauge.
-
Connect the force gauge to an appropriate power supply (refer to “Grounding Instructions” in this manual).
Note: If using an extension cord, it must be rated for 20 amps. Use the shortest cord possible. Longer cords reduce puller speed. -
Position the force gauge so that it can be monitored by the puller operator.

Turn the circuit breaker in the force gauge ON (I).
-
Grasp the tailing end of the rope. Apply a slight amount of tailing force.
-
Turn the puller ON (I).
-
Tail the rope, allowing the spent rope to accumulate on the floor between the operator and the puller.
-
When the pull is complete, turn the puller OFF (O).
Tie off the rope and anchor the cable.
WARNING
Entanglement hazard:
Do not wrap rope around hands, arms, waist, or other body parts.
Do not stand in spent coils or tailed rope. Hold rope so that it may be
released quickly.
Failure to observe this warning could result in severe injury or death.
Removing Cable
Removing old cable involves the same principles as installing new cable.
However, there are some important differences.
Pulling Force
It is difficult to predict the amount of pulling force necessary to remove an
old cable. The cable may be damaged, and it may break with an unexpectedly low
pulling force.
The required pulling forces may be very high:
- The cable has probably “taken a set.” Unlike the new cable on a reel, cable in conduit has probably been in the conduit for years, or perhaps decades. The cable will resist bending and straightening as it is pulled through the conduit.
- The pulling lubricant has probably hardened, increasing pulling resistance.
- The insulation may be damaged and the cable may be corroded.
- Dirt or other foreign matter may have entered the conduit and may have cemented the cable in place.
Using a Force Gauge
When pulling old cable out of a conduit, the pulling force will be highest
when starting the pull. Select a cable puller and pulling components to meet
or exceed the estimated amount of pulling force necessary to remove the old
cable. Because breaking the cable free will require the largest amount of
pulling force, it is necessary to use a force gauge to prevent overloading the
system components. Use the 07120 Force Gauge Unit.
Carefully monitor the pulling force at the force gauge; if the puller is not
able to begin the pull, shut off the puller and disassemble the setup. Start
over with a puller and components of a higher force rating.
Puller Placement
Pulling out old cable is generally accomplished with the puller located some
distance away from the end of the conduit. This allows the pulling crew to
pull out a long section of cable before turning off the puller, cutting off
the cable, and reattaching the grip(s). Mounting the cable puller a distance
away from the end of the conduit increases the amount of exposed rope, which
greatly increases the amount of violent whipping action which would occur if
the rope were to break.
To isolate the operator from the rope path:
-
Locate the puller so that you will stand behind an obstruction, such as a wall. Set up the puller so that you will be able to maintain control of the pull. You need a clear view of the rope as it feeds onto the capstan, including several feet of the rope in front of the capstan. You must be able to turn off the puller before the pulling grip, connector, or swivel contacts the capstan.
-
Use an additional pulling sheave to change the direc-tion of the tailing rope. Anchor the sheave so that you are close enough to maintain control of the pull.
You need a clear view of the rope as it feeds onto the capstan, including several feet of the rope in front of the capstan. You must be able to turn off the puller before the pulling grip, connector, or swivel contacts the capstan.
Note: Use the additional pulling sheave to change the direction of the tailing rope (after the rope leaves the capstan). Do not change the direction of the pulling rope. -
Use a longer tailing rope than usual and stand away from the puller. Stand as far from the puller as pos-sible, while maintaining control of the pull. You need a clear view of the rope as it feeds onto the capstan, including several feet of the rope in front of the capstan. You must be able to turn off the puller before the pulling grip, connector, or swivel contacts the capstan.
