operation and extends the usable life of the vehicle.
When you are operating the bucket, safety of operation
should be your prime concern. Although the bucket is
insulated, all personnel should maintain a constant
awareness of the hazards of operating in and around
high-voltage power lines.
Another high-production piece of line equipment is
the earth auger. This truck-mounted unit, as shown in
figure 4-39, is designed to dig holes up to 7 feet deep and
comes with different sizes of auger bits to enable you to
vary the diameter of the hole. The auger truck usually
has a winch attached that enables it to be used to set
poles and other attachments that allow it to install some
types of guying anchors. These features are normally
used when a framing crew is assigned with the auger
truck. They install all line hardware on the pole before
they set it in place (except when the hardware is too
heavy) and place the anchors. This method is used
when long power lines are being constructed. It
requires less pole time for the linemen and enables them
to devote more time to stringing conductors, installing
the line equipment, and making connections on the
MANUAL LIFTING EQUIPMENT
There are many different types of manual lifting
equipment used in line work. Some of the various types
and uses of manual lifting equipment are discussed in
the paragraphs below.
The pole gin, as shown in figure 4-40, is designed
for temporary attachment to a pole. It provides a secure
point for attaching other lifting equipment, such as a
block and tackle used in lifting heavy objects, for
mounting on the pole. Transformers, capacitors,
regulators, heavy lighting fixtures, and heavy crossarms
are a few examples of the types of equipment that may
be lifted by using the pole gin.
When you are lifting a distribution transformer, it
should be handled carefully. Bushings and other
equipment on the transformer can be damaged easily.
The windings of the transformer may be damaged if the
