RC Instruction Manual
Routing The Working Line -
RC-3001 Lowering Device
The following instructions demonstrate the correct routing of the working line to achieve a 3:1 tensioning system. Only ever
use the RC-3100 with a Prusik Loop as demonstrated. Never substitute the prusik for/in favour of a rope-grab.
(1)
Remove as much slack as
possible from the working line
and tie off using the fairleads
on the lowering device.
(2)
Attach a suitable prusik loop
to the working line using
either a 4-wrap or 6-wrap
prusik knot. More wraps give
extra grip.
(3)
Attach the RC-3100 to the
prusik loop by hooking the
device onto the loop by
means of the prusik retention
bar
(4)
Raise the prusik loop and
pulley up the line then release
the working line from the
fairleads leaving one wrap
around the bollard
(5)
Create a loop in the line and
route it over the pulley wheel
whilst keeping tension on the
line. The line goes in between
the retention bar and wheel
(6)
By pulling down vertically on
the line exiting the pulley this
will start to remove slack from
the main line.
(7)
To get extra tension securely
hold the end of the working
line which enters the pulley,
then release the line from the
pulley.
(8)
Tie off the working line and
repeat the process over until
the desired tension has been
achieved

This technique can be used on both the RC-1000 and RC-2000
Lowering Devices. When using the RC-3100 Pre-Tension
Pulley with both the RC-1000 and RC-2000 the working line
must remain within the top fairlead.

WARNING
ALWAYS ENSURE THE WORK AREA IS FREE &
CLEAR OF ANY OBSTACLES AND A FULL
RISK ASSESSMENTS HAS BEEN UNDERTAKEN
BEFORE USING THE RC DEVICE
This process of tensioning should only ever be carried out by one person. More than one person can exceed the RC-3100 WLL (working load limit).
Never try to achieve more tension by impact loading the pulley i.e. tugging repeatedly on the working rope.
If additional tension is required over and above what is possible by using the RC-3100 seek advice.
