The Mechanical Advantage Piggyback Method is a powerful and advanced rope rescue technique that provides precision, safety, and flexibility during raising operations—especially when encountering knots in the rope system. This method leverages an auxiliary mechanical advantage (MA) system, such as an AZTEK kit, to temporarily assume load-bearing responsibility, enabling rescuers to reposition and manage the

In rope rescue scenarios, particularly those involving raising systems, managing a mid-line knot can be a critical challenge. Whether the knot results from extending rope length or bypassing damaged sections, failure to address it safely can bring operations to a halt. Fortunately, integrating a Prusik hitch into the system offers an efficient and controlled method

Twin Tension System Knot Pass for Raising Operations – The Twin Tension System (TTS) offers a significant advantage in rope rescue operations, particularly when navigating knot passing during raising evolutions. This method uses dual mainlines and staggered knot positions to allow continuous control of the load, enabling one side of the system to manage tension

The Lowering Piggyback Method is a rope rescue technique used to maintain continuous descent control while safely bypassing a knot in the main line. This method incorporates a secondary descent control system—known as the piggyback—and provides a controlled process for transferring loads when a knot prevents further lowering. Ideal for systems using the Clutch, MPD,

Mechanical Advantage Piggyback Method for Rope Rescue Transitions – The Mechanical Advantage Piggyback Method is an advanced rope rescue technique used to safely and efficiently pass knots and transition loads during lowering or raising operations. By incorporating a self-contained mechanical advantage (MA) system—such as an AZTEK kit—teams can bypass rope knots without interrupting the primary

The Twin Tension Knot Pass with a Prusik Hitch is a valuable technique used in rope rescue operations to manage mid-line knots during lowering or hauling. This method maintains load control, enhances system redundancy, and ensures continuous rope operation through safe, structured load transfers. Especially effective when paired with devices like the CMC Clutch or

Twin Tension Knot Pass Using a Figure 8 Loop – In lowering systems configured as twin tension rope systems, passing a knot becomes more manageable—particularly when the knot locations are intentionally staggered between the two lines. This strategy allows for momentary load transfer to one side, effectively transforming the system into a main and belay
