• As needed, pull the Sideplate fully open using
the thumb of the hand holding CAPTO. This will
move the Cam completely out of the way for
rope installation.
• Close CAPTO by rotating the Sideplate to the closed
position as described above. Listen for two audible
"clicks" and visually check that the Sideplate is
fully closed.
• Function test CAPTO to confirm that the rope
is correctly installed and the device is working
properly. Always use a backup safety system when
performing this test.
Removal:
• Remove any load that may be acting on CAPTO.
• Push CAPTO a few centimeters toward the anchor /
load to disengage the Cam.
• Open the Sideplate by actuating the Sideplate
Release Button twice. When the Sideplate is fully
opened, it also moves the Cam away from the rope
for easy removal.
• Take CAPTO off the working line, removing rope
from the pulley if needed.
WARNINGS:
• Do not load CAPTO unless the Sideplate is fully
closed and the Sideplate Release Button has
returned to the lower position. See figure 6A.
• Do not attempt to release the Cam while the device
is under load.
• If the Cam is engaged, do not attempt to pry it off
the rope using the Sideplate. Instead, disengage the
Cam by moving CAPTO a few centimeters toward
the anchor / load.
• Ensure that the rope follows the path indicated by
the laser markings and illustrations. See figure 6B.
• Make sure the rope does not pass above the Rear
Rope Guide.
• Do not load CAPTO as a high line trolley. It is not
intended to support a perpendicular load when
placed on a tensioned line. See figure 6C.
• Do not install the rope directly from the rope grab
into the inner pulley track. See figure 6D.
• Installing the rope through the rope grab and
around the outside of the pulley will allow for prog-
ress capture in a 1:1 haul. Use in this configuration
should be limited to taking up slack. CAPTO is not
intended to be used as a progress capture pulley.
Use in this manner could cause premature wear to
the rope or device. See figure 6D.
Use in Hauling
CAPTO is designed to function as a Pulley Rope
Grab (PRG) in haul systems. In this configuration,
CAPTO works in combination with a Progress Capture
Device (PCD), such as a belay / rappel device or
a self-braking descender like the CMC CLUTCH by
Harken Industrial™. Install CAPTO in a fixed position
on the working line between the PCD and the load,
and use the integrated pulley and becket to add the
desired mechanical advantage.
3:1 Mechanical Advantage System
Open CAPTO as previously described and install it
on the load line going to the PCD. Take the tail end of
the rope coming from the PCD and pass it around the
CAPTO pulley in the direction indicated on the laser
markings and shown in the illustrations. Ensure the
30
Sideplate is fully closed before loading the system
and hauling with this simple 3:1 Z-Rig.
5:1 Mechanical Advantage System
To progress from a simple 3:1 to a simple 5:1
mechanical advantage system, use appropriate
connectors to attach a pulley at the PCD side of the
system and another pulley to the CAPTO becket.
Take the tail side of the rope coming from the CAPTO
pulley and thread it through the additional pulleys.
Make sure to orient the pulleys in line with the rope.
Swivel pulleys are recommended for this purpose
but not required. A number of additional mechanical
advantage systems can be built using CAPTO's pulley
and integrated becket.
Re-Setting the System
To re-set the haul system, release tension on the haul
strand and push CAPTO toward the load. The becket
provides a useful point of leverage to reset the device
to the desired position. Installation of an optional
accessory loop can also provide a place from which
to pull / re-set CAPTO.
To collapse the haul system, ease the haul strand and
push CAPTO a few centimeters toward the load to re-
lease the Cam. Use a thumb on the Cam Grip to hold
the Cam open and slide CAPTO towards the PCD.
Use in Ascending
When using CAPTO as an ascent device, attach a
lanyard into the CAPTO becket using a compatible
connector. Attach additional personal ascent
equipment as needed such as a foot loop or etrier.
Function test CAPTO to confirm that the rope is
correctly installed and the device is working properly.
Always use a backup safety system when performing
this test.
To remove CAPTO, refer to the previous Installation
& Removal section. Use of a lanyard attached to the
CAPTO becket creates a retention system to prevent
dropping the device. The technique for stowing
CAPTO on a harness gear loop may differ depending
on the type of connector being used. The width of the
CAPTO becket may prevent it from rotating around
the spine of D-shaped carabiners. In most cases,
the becket can pass over the carabiner gate to hang
naturally when clipped to a gear loop. If using a
carabiner with an especially large gate, such as an
ANSI-compliant connector, it is recommended to use
an oval carabiner to allow becket rotation along the
spine. In this case, it is also best to clip into CAPTO
first before attaching additional equipment such as a
lanyard and/or foot loop.
To move CAPTO toward the anchor during personal
ascent, push / pull the device to slide it along the
working line. To make upward progress, use CAPTO
in conjunction with a PCD, such as a chest ascender
or self-braking descender. Take extra caution when
approaching knots, anchors, or intermediate anchors.
Keep the device at or above the user connection point
to eliminate the potential for falls with a fall factor
greater than 1.
To release the Cam for the purposes of descending a
line, begin by removing any load acting on the pulley
and becket. Push CAPTO a few centimeters toward
the anchor/load to disengage the Cam. Use a thumb
|
CMCPRO.COM
on the Cam Grip features to rotate the Cam away from
the rope as shown in the illustrations. Slide CAPTO
along the line while holding the Cam open. Remove
the thumb to allow the Cam to re-engage where
desired on the rope.
WARNING: Do not attempt to release the Cam while
the device is under load. CAPTO will not grab rope
when the Cam is manually held open.
Use in a RAD System
CAPTO can be used in combination with a self-brak-
ing descender to build a Rapid Ascent/Descent (RAD)
System. A RAD System adds mechanical advantage
and is recommended for ascents involving heavier
loads, significant tail weight, or short climbs requiring
efficient transitions between ascent and descent.
To build a RAD System, begin by installing and
function testing the chosen self-braking descender.
Open CAPTO Sideplate and place it on the working
line between the descender and anchor. Pass the
rope tail from the descender around the CAPTO
pulley in accordance with the laser markings. This
creates a 3:1 mechanical advantage when operated
by the climber.
Close CAPTO Sideplate and function test the device.
Attach additional equipment to the CAPTO becket as
needed, such as a lanyard and foot loop. Progress
upwards by pushing CAPTO toward the anchor then
stepping up in the foot loop while pulling down on the
rope tail exiting the CAPTO pulley.
Descent can be accomplished by down-climbing
with CAPTO as previously described or by removing
CAPTO from the working line and operating the
self-braking descender.
Always use a set of two ropes, main and back-up,
when ascending and descending on rope systems.
This device is only intended to be used as a means of
progression on a rope and is not intended to function
in a fall arrest system.
Use as a Pulley
The primary function of the CAPTO pulley is to aid in
building mechanical advantage systems. It can also
be used as a stand-alone pulley by using the CAPTO
becket as the pulley attachment point. Refer to the
associated illustration for pulley attachment method
and orientation.
The CAPTO pulley is strength rated only when the
becket is used as the pulley attachment point. If
CAPTO rope grab is used as the attachment point
rather than the becket, then the stated pulley MBS
does not apply. Additionally, this configuration limits
the amount of force that can be applied to the pulley
because CAPTO rope grab is designed to slip on rope
when overloaded (for example when more than 4 kN
is applied to the pulley or becket). For safe operation
of CAPTO and its components, do not block the rope
grab with a stopper knot or otherwise prevent the
device from slipping on rope.
Accessory Loop Attachment
CAPTO has a hollow Cam axle (4 mm diameter)
that allows for the attachment of an accessory cord
