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.

Cable Pulling Principles (cont’d)

Cable Pulling Theory Illustrated

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 direc-

tion of force is changed, where necessary, with pulling

sheaves.

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 import-

ant the anchoring system can withstand this amount of

force. Refer to “Typical Setup: Floor Mount” for proper

setup or installation.

Cable Pulling Forces (cont’d)

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 coefcient 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 coefcient 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.

This table shows how the capstan acts as a force

upon the condition of the rope and capstan, this formula

cannot determine an exact amount of pulling force.

Stored Energy

Cable Pulling Forces (cont’d)

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 newton-

meters 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 Super Tugger cable

puller. Select a double-braided composite rope with an

average rated breaking strength of at least 115.6 kN

(26,000 lb).

Cable Pulling Forces (cont’d)

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.

1. Select the correct type based on the descriptions

of each type in the Greenlee catalog.

2. 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 pro-

vided to nd the correct size.

3. See the maximum rated capacities in the Greenlee

catalog.

Typical Resultant Force at Sheave

Cable Pulling Forces (cont’d)

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 struc-

tures illustrated.

The resultant amount of force depends on the angle of

the change in direction. A brief table is provided here;

for more details, see IM 1363 (99929988).

Cable Pulling Principles (cont’d)

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 dura-

tion 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 neces-

sary 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 com-

pletely 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.

While the rope and cable are under tension, it is import-

ant 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 acceler-

ate 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 sufcient

amount of pulling force to pull in the rope and cable.

Too much tailing force is any amount more than is nec-

essary 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 difcult 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 start-

ing 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. See 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!

Cable Pulling Principles (cont’d)

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 com-

ponent 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 oor 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.
