Tool Operation - Greenlee Pull Assist Manual De Instrucciones

Tool Operation

• Rope and V-Pulley can entangle and crush
• Keep hands and body away from rope,
capstan, and V-Pulley. Fingers and hands
can be crushed, fractured, or amputated if
they become caught between the rope and the
V-Pulley.
• Do not wrap rope around hands or body. Do
not stand in spent coils or tailed rope. Hold rope
so that it may be released quickly. Entanglement
in rope could result in severe injury or death.
• Do not allow rope to overlap on the capstan.
Properly align rope on capstan with rope ramp
and V-Pulley. If an overlap occurs, immediately
stop the cable puller and relax the tailing force.
• System components can break, allowing
whipping rope, flying parts and injury
• Do not stand in line with the rope during use.
The rope is under tension and could break.
• Do not maintain a stationary rope on a
rotating V-Pulley. A worn rope can break under
tension and whip violently.
• Only use double braided nylon pulling rope
in good condition and recommended for the
puller in the IM. A worn or underrated rope can
break under tension and whip violently.
• Do not add wraps to a rotating capstan. Rope
could overlap and limbs could get caught between
the rope and capstan resulting in crushed limbs.
• Do not lock foot switch in ON position. The
operator should always be in control of the tool
to reduce the risk of injury from uncontrolled
movement.
• Maintain communication between operators.
Loss of communication increases the risk of injury
and damage to the tool and cable.
• The rope is still under tension when the V-Pulley
is stopped. When removing rope from the V-Pulley,
be prepared to hold the tailing force and maintain
the pull manually to avoid injury.
*
The Pull Assist automatically adjusts the tailing force to attempt to
maximize the speed, the dial sets an upper limit on the allowable
tailing force: it does not directly control the tailing force.

1. Assume a proper operating position. Stand to the
side of the puller so the control panel is visible and
the rope tail is within arms reach.
2. Confirm the Pull Assist and work area has been
properly set up and inspected according this
manual and the manuals of any other equipment.
3. Use the pendant to control
the tailing force limit*. (Fig.7)
Increase or decrease the tailing
force limit by turning the dial.
The green zone is for continuous
operation, while the yellow
zone should only be used
intermittently when extra force is
required.
If the rope starts to slip on the
capstan, increase the tailing
force limit. If you're already at the
maximum setting, step off the
footswitch, add another wrap to
the capstan, and then resume
the pull. To slow the pull or to
decrease puller load, decrease the tailing force limit.
If you're already at the minimum setting, step off the
footswitch, remove a wrap from the capstan, and
resume the pull.
The gray zone is the minimum setting, the V-Pulley
may appear to stop but it is still applying tailing
force to the rope. Step off the foot switch before
removing the rope from the V-Pulley to add or
remove a wrap.
4. Start the pull. Press the foot switch to start the
rotation of the puller and Pull Assist. The LED on
the pendent will start flashing to indicate that both
machines are running.
• To switch to hand tailing, stop the pull, remove
the rope from V-Pulley and route the tailing rope
around the right-angle sheave and continue the
pull according to the instructions in the puller's
manual.
5. Manage the tailing rope to keep it from piling up
next to the puller. Move the rope away from the
puller or into a storage container (spool, bucket,
etc.). Do not stand in the spent coils of rope. Coils
of rope create a tripping and entanglement hazard
that could result in injury.
Avoid pulling on the tailing end when handling the
tailing rope. This can cause the rope to jam in the
V-Pulley, which will interrupt the pull and could lead
to tool damage
6. When the pull is finished, turn off puller and Pull
Assist. Remove the rope from the V-Pulley by lifting
the rope retention lever and lifting the rope out of
the V-Pulley. Then unwrap rope from the puller
capstan.
