WARNING
Inspect puller and accessories before use. Replace
any worn or damaged components with manufacturer
replacement parts. A damaged or improperly assembled
item can break and strike nearby personnel with sufficient
force to cause severe injury or death.
WARNING
Entanglement hazard:
• Do not operate the cable puller while wearing loose-
fitting clothing.
• Retain long hair.
Failure to observe this warning could result in severe
injury or death.
Wear eye protection when using this
tool. Failure to wear eye protection
could result in severe eye injury from
flying debris.
Cable Pulling Glossary
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 kilonewtons (metric)
or pounds; the maximum rated capacity of every
component must meet or exceed the maximum
pulling force of the cable puller.
Newton (N)
A metric unit of force, equivalent to 0.225 pounds of
force.
WARNING
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 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 newton-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).
Tactile feedback
The way the rope feels as it feeds off of the capstan;
the feel of the rope provides information about the
progress of the pull to the operator.
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—refer
to the complete explanation under "Cable Pulling
Principles".
Wire grip
Connects the rope to the cable; some use a set
screw to clamp onto the conductors of the cable.
