4.20 Underground Installation Methods
Underground Placement Equipment
Underground Equipment
Shoe, Cable
This equipment is used to
route conduit through manholes
while the conduit is being pulled into
place. Placement of the cable shoes
will prevent the rubbing of the conduit
on obstacles within the manhole.
Sheave
This equipment is used to facilitate
the movement of conduit that is
being pulled into place through
a manhole. Sheaves are free
wheeling and accordingly
add little drag to the conduit
that is being installed. The
placement of the sheave
will prevent the rubbing of
the conduit on obstacles
within the manhole.
Breakaway Swivel
Used to prevent excessive
pulling tension. It is
designed to break
should it exceed a
pre-set tension limit.
Pulling Sling
Used to prevent both excessive pulling tension and
twisting of conduits in multiple conduit installations. It
is designed to break should it exceed a pre-set tension
limit.
Winch, Cable
A cable winch is a powered
capstan used to pull cable. This
equipment will often be used as
an intermediate assist in pulling
cables or conduits that are very
long or have considerable
drag.
Come-A-Long
This equipment is used to facilitate the movement
of innerduct that is being pulled into place through
existing conduit.
