The come-along, a pulling tool, is normally used for
dead-ending line conductors or installing guy wires
(fig. 4-46). It is designed with a ratchet action that can
be used to pull or release strain by placing the forward or
reverse lever in the desired setting.
The wire grips, as shown in figure 4-47, view A, are
engineered to grip the wire and hold it when pulling or
slow release is desired. It is used in the sagging
operation and also in applying strain to the guy wire
during installation. Different designs of wire grips are
used, and you should ensure that you have the right one
before you attempt to pull with them.
A grip that is similar to the wire grip is called the
bulldog grip. This grip, as shown in figure 4-47, view B,
is made for pulling large objects, such as ground rods.
When pulling conductors, do not use this grip; it will
cause damage that cannot be repaired.
SETTING POLES AND INSTALLING
HARDWARE AND CONDUCTORS
Constructing a pole line involves such functions as
framing; setting poles; and installing crossarms,
hardware, and conductors. The paragraphs that follow
will cover these elements of work and give you a better
understanding of how the construction is accomplished.
Framing a pole consists of the following actions:
determining the face and back of the pole, cutting the
roof and gain, and drilling holes for mounting hardware.
