anchoring system

any item or group of items that keeps a cable pulling

component in place during the cable pull

capstan

the hollow cylinder of the cable puller that acts on the

pulling rope to generate pulling force

coefficient of friction

the ratio that compares two amounts of force:

(1) the force needed to move an object over a surface and

(2) the force holding the object against the surface

This ratio is used to describe how the capstan and the

rope work together.

connector

any item, such as a wire grip, clevis, swivel, or pulling

grip, that connects the rope to the cable

direct line of pull

the areas next to the pulling rope and along its path;

this includes the areas in front of, in back of, and

underneath the rope

maximum rated capacity

the amount of pulling tension that any component

can safely withstand, rated in kilo-Newtons (metric)

or pounds; the maximum rated capacity of every

component must meet or exceed the maximum pulling

force of the cable puller

Newton

a metric unit of force, equivalent to .225 pounds of force

pipe adapter sheave

attaches to conduit for pulling or feeding cable

pulling grip

connects the rope to the cable; consists of a wire mesh

basket that slides over the cable and grips the insulation

pulling force

the amount of pulling tension developed by the cable

puller, rated in Newtons (metric) or pounds; a cable

puller is usually described by the maximum pulling force

that it can develop

resultant force

any force that is produced when two or more forces act

on an object; applies to the sheaves of a cable pulling

system

rope ramp

a device that works with a tapered capstan; guides the

rope onto the capstan to help prevent rope overlap

sheave

a pulley that changes the direction of the rope and cable

stored energy

the energy that accumulates in the pulling rope as it

stretches, described in Newtons-meters (metric) or

foot-pounds

support structure

any stationary object that a cable pulling system

component is anchored to, such as a concrete floor

(for the floor mount) or an I-beam (for a sheave)

tail

the portion of the rope that the operator applies force to;

this is the rope coming off of the capstan, and is not

under the tension of the pull

tailing the rope

the operator’s main function; this is the process of

applying force to the tail of the pulling rope—see the

complete explanation under Principles of Cable Pulling

wire grip

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.
