1. Start by attaching the rope end to
the becket and then route rope down
around a sheave on the Advance Tech
Mate Pulley.
2. Then bring rope back up to the Advance

on the non-cam side and then over

3. Repeat routing rope through the
Advance Tech Mate and then finally
bring rope up behind the guide pin
on the cammed side of Pulleys before
going over the sheave to form the rope

Releasing A Loaded Cam – While maintaining
control of the load, slightly raise the load by
pulling on the tail of rope while at the same
time releasing the cam. The cam can then be
rotated into the parked position, held open by
hand or by pulling the cord while lowering the
load. Use caution so that fingers or gear are not
drawn into Pulleys mechanism.
CAUTION: Always maintain control of the rope
tail until you are certain that the cam has
engaged and is holding the load. Failure to
maintain control of the load may shock load the
system which could result in serious injury or
death.
CONFIGURATION RATINGS
The Advance Tech Pulleys are designed primarily
for rigging small lightweight mechanical
advantage systems typical in rescue situations.
Park
Cammed Pulleys, like ascenders and other
similar gear, require aggressively toothed cams
to quickly and positively engage.
these same aggressive teeth may be harmful
to ropes if the cam is employed in high load
situations. For situations when high loads
are present the Advance Tech HX becomes
a very effective prussic minding Pulleys by
disengaging the cam and using prussic's.
Simply attach prussic's in the normal manner
and move cam to the parked position assuring
that the teeth are out of the rope path. The
stainless guide pins allow for better prussic
minding than all other prussic minding Pulleys.
CAUTION: Stainless guide pins should not be
used as attachment points.
It can be difficult to judge when loads will
exceed the designed capacity of the cam and
the use of prussic is required. The following
strength data has been provided for guidance
in making rigging decisions.
