General Machine Products 15472 Fiber Optic Mid-Assist Capstan 25 in., 32 in. and 40 in. - Manual

Fiber Optic Pulling Capstans
Description & Use
Your new GMP Fiber Optic Pulling Capstan is a
versatile and highly productive tool for placing
fiber optic cable. It is based on GMP's accessory
approach to fiber cable placing that lets you use
your existing pulling equipment, winches and
capstan drives, without special modifications or
expensive new pulling equipment.
Virtually anywhere you have used a CR Collapsi-
ble Reel or RS Power Reel you can now use this
fiber puller. Its durable construction and mini-
mum number of components give it a remarkably
long, trouble-free service life. The large working
diameter of the capstan translates into good pull-
ing speed and you can pull with rope, tape, or pull
the fiber cable itself. This means that the Fiber
Optic Pulling Capstan can be used both as an end
puller or a mid-assist booster puller.
Any of these units can be easily mounted on a 2-
7/16 in. (62 mm) diameter drive shaft with either
a bayonet or a cross pin type of connection.
IMPORTANT PRECAUTIONS
Before you begin placing cable, you should be
completely familiar with the control and opera-
tion of the vehicle, power take-off, winch or cap-
stan drive controls and all of the other pulling
equipment you will be using. The operator should
never leave his position at the controls while the
pulling line is under load or the winch power
take-off is engaged. All members of the crew
along the entire length of the intended pull should
be in visual communication by hand signals or
voice communication at all times.
Make certain that all vehicles and trailers are se-
cured with wheel chocks. Make sure your work
area is properly posted with signs, flaggers and
other advance warning devices in accordance
with company practices. Federal, State and local
regulations for the protection of the crew and the
public. You'll find everything you need in our
Safety Catalog.
If you are pulling from a drum shaft extension on
a bed winch, de-clutch so that the drum is in free-
spool, wind all of the wire rope onto the drum and
secure it using a winch line holder. This will keep
the wire rope from spooling off the drum and be-
coming entangled.
Do not stand inside of angles formed by the pull-
ing line or cable. As much as possible, do not
stand where there is the danger of being struck by
the pulling line if it should fail or snag. Never
place hands on a moving pulling line. To prevent
entanglement in moving parts and possible seri-
ous injury, do not wear loose fitting clothing
when working around the winch, capstan, sheaves
and pulling line.
General Physical
Features
There are several models
of capstans available:
P/N 15470 P/N 15472 and
P/N 15479 each consist of
an aluminum alloy capstan
drum measuring 27-1/2 in.
(698 mm) outside flange
diameter and a 25 in. (635
mm) diameter X 5 in. (127
mm) wide working sur-
face. The capstan drum is
bolted to an inner hub and
drive spindle by means of
three 1/2 -13 x 1-1/4 in.
cap screws with 3/4 in. (19 mm) hex heads.
P/N 15470 is a capstan mounted directly to the
inner hub and drive spindle with no torque limit-
ing capability. With this unit the pulling tension
must be limited by means of a break-away swivel
or by limiting the hydraulic system pressure to
achieve a maximum allowable torque.
P/N 15472 is a capstan equipped with an integral
torque limiter between the driving spindle and the
inner hub. The torque limiter limits the pulling
tension to a calibrated maximum that has been set
at the factory to 600 pounds-force (2669 N).
P/N 15479 is a capstan equipped with an integral
torque limiter between the driving spindle and the
inner hub. The torque limiter limits pulling ten-
sion to a calibrated maximum that has been set at
the factory to 1000 pounds-force (4448 N).
P/N 70351 consists of an aluminum alloy capstan
drum measuring 34-3/4 in. (883 mm) outside di-
ameter and a 32 in. (813 mm) diameter X 7-1/2
in. (191 mm) wide working surface. The unit is
equipped with an integral torque limiter between
the driving spindle and the inner hub. The torque
limiter limits the pulling tension to a calibrated
maximum that has been set at the factory to 600
pounds-force (2669 N).
P/N 70381 is same as 70351, but provides pulling
tension of 750 pounds-force (3336 N).
