Rock Exotica has reinvented the machined pulley. Their machined pulleys are milled from solid 7075 aluminum, which allows anyåÊmaterial to be removed from where it's not needed and left it where it is required. The axle is machined as part of the side plate, allowing for a flush head axle screw. That's why these pulleys are more compact, stronger and lighter weight than conventional stamped pulleys.
The Aztek Compact 4:1 Mechanical Advantage is a highly compact MA system that continually amazes rescuers with its many uses and versatility. Even with 8mm rope, the system maintains a strength of 36kN.
Some of applications for the Aztek include use as a pick off, travel restrict, adjustable directional, high directional guyline, high angle attendant tether, high angle litter scoop, load release hitch and much more. Each of the̴Ì_Aztek pulleys have their own colour-coded prusik and can be easily activated or deactivated. This means you can have the ratchet at either the top pulley or the bottom pulley. The special 3-on-2 prusik cannot come off the rope, so the deactivated prusik will stay ready to be used as soon as you need it.
You cannot appreciate how smooth and easy use of the prusiks is until you experience it. Because the prusik only sees a fraction of the total load in an MA system, they don't get too tight and they are easy to release and very controllable.
This system grew out of extensive use and experimentation of small MA systems by Ropes That Rescue and is light-years ahead of anything else. If the world as we know it ends and you need an MA system to help you rebuild civilization, this is the one!
