Figure 4-42 shows examples of a lifting strap and a
chain. For a detailed explanation of uses, strengths, and
various types of lifting straps and slings, refer back to
A snatch block (fig. 4-43) is a single sheave block
made so that the shell opens on the side at the base of the
hook to permit a rope or line to be slipped over a sheave
without threading the end of it through the block.
Snatch blocks ordinarily are used when it is necessary to
change the direction of the pull on a line.
While working on a power pole, every lineman
should carry a handline. It can be used for lifting or
lowering smaller objects and also for holding
transformers and other equipment away from the pole
as it is being raised. The handline is usually made of
1/2-inch manila rope, approximately 30 to 35 feet long,
and has a manufactured or self-made metal hook
attached to one end. The handline is personal
equipment and can be configured to best suit the
individual or the job to be accomplished.
The pulley line, as shown in figure 4-44, is another
lifting tool and is used to replace the handline when
large quantities of material must be lifted to the top of
the pole. When the pulley line is used in this way, the
lineman can continue working, while the materials are
being supplied by the groundman.

Another manual lifting device is the pole jack, as
shown in figure 4-45. It is designed for easy attachment
and removal from the pole and provides an unpowered
mechanical lift that is used to straighten or remove
