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.
Constructing a pole line involves such functions as framing; setting poles; and installing crossarms, hardware, and conductors. The paragraphs that follow
