The AZTEK system is used in rigging programs around the world. These, configured as “set-of-fours” (double blocks) will enable the rescue practitioner greater versatility in a personal mechanical advantage (PMA) for rescue and general rigging. The swivel Omni pulleys (blocks) are hewn from a solid block of high strength aluminum and are engineered with great pride to withstand over 8,000 lbs (36kN) of tensile force end to end.
Here is a compact mechanical advantage system that continually amazes rescuers with its many uses and versatility. Some of the uses are 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. Both Aztek pulleys have their own color-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.
Turn the set-of-fours one way and you have a 5:1 mechanical advantage. Turn it around and a 4:1 w/change of direction is the result, making this PMA extremely versatile. Also, the progress capture ratchet prusik can be attached at either end (orange to orange, or blue to blue). The progress capture prusiks are laced onto the restraint cord and then formed into a directional prusik hitch (3 on 2), which prevents the inadvertent loss of the prusik once assembled. One quick pin is sold with each set of blocks. Additional pins may be purchased if needed or if one wished to hold a spare in the opposite block.
Complete system with two Aztek pulleys, main rope (8 or 9mm), two Prusiks, a travel restrict Prusik. 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. It 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.
