In this sequence we address the 5 basic rules of constructing a simple mechanical advantage with pulleys and pulley systems. This information has been handed down over centuries through the mariners industry and they still hold true for today in a very useful understanding.
The first rule is… if the rope is tied off at the anchor it is always going to be even. It’s going to be a 2:1, a 4:1, a 6:1, 8:1. Here we have a 2:1. It’s tied off at the anchor.
Rule number 2 says, if it’s tied off at the load it is always going to be odd…

The way we address knots, MAs (Mechanical Advantages), and Anchors in these videos are more general and with a focus of the finer points that are many times overlooked. Our hopes are that the viewer walks away with an energized commitment to studying the “WHY” behind general rigging, and focus on an extremely clean approach and a dedication to practice and muscle memory. We will explore the finer points of these topics that are applicable to anyone who is called upon to rig.
Commitment to rigging as an art form is the true storyline.
Sterling Rope is the Official Rope of Rescue Response Gear’s The Rigging Lab. The Lab uses Sterling’s 11mm HTP Static for many of our rigging systems. A multi-use rescue/rappel rope that resists moisture and has high abrasion resistance. 100% polyester static provides significantly lower elongation and is perfect for any haul system. Ideal for high traffic expeditions, mountain rescue, military, industrial rope access, and swift-water rescue uses.
