6.0 INTRODUCTION TO CABLE PULLING
Each cable pulling operation can be different. Only
experienced personnel should be responsible for setup and
operation of this equipment. During a cable pull, very high
forces can be developed. Any failure of the components of
the system can be dangerous.
WARNING: All pulling system components must be
rated to withstand the maximum pull forces.
Safe and efficient cable pulling will require knowledge of the
following subjects.
1. Planning
Each operation will need its own special set up. Selection of
the proper sheaves, ropes and puller is critical.
Planning the length of the pull is another important
consideration. Cable weight and internal conduit bends will
create resistance to the pull. Size of conduit and cables
already present must be considered. To keep the pulling
force within equipment specifications, shorter pulls may
be required.
2. Installation
Make sure the puller is secured in place. Fastening the puller
to the floor can be accomplished by using the four through
holes on the puller base. Position the puller so the force is
parallel to the conduit. When securing components to other
objects, make sure they can support the pulling force.
3. Safe Operation
Know what the limits of your puller are. Always check
equipment for damage prior to operation.
WARNING: All pulling system components must be
rated to withstand the maximum pull forces.
CAUTION: Check all pulling system parts before
use. Never use worn or defective components.
Thoroughly inspect the work area. Make sure ample space is
available for equipment and personnel. Check for secure
footing and ventilation of any combustible gasses.
WARNING: Only operate in well lighted areas.
DANGER: Do not operate in an area that contains
hazardous or combustible material. A fire or explosion
can result.
Capstan Theory
The capstan uses the friction of the pulling rope to multiply
force. The total pulling force is determined by:
1. Number of wraps of rope on the capstan.
2. Tailing force the operator applies to the rope.
With the full 5 wraps of rope on the capstan, the operator can
easily generate sufficient pulling force for most applications.
For the best operator control during cable pulling, use the
fewest rope wraps needed to maintain an even pull. Only add
more rope wraps to the capstan if the operator needs
additional leverage. Never add or remove wraps from a
moving capstan.
