Multipoint Anchors Building an anchor system requires much practice and experience. In the end, simplicity and complexity are competency issues. Competency takes time to build and this doesn’t come without an investment of focus and purpose. Building an anchor system requires much practice and experience. When dealing with structures, chose anchor points that are part …
Fast Fours Mechanical Advantage System The Fast Fours is a simple variation on a standard set-of-fours. The difference is that the far end of the rope is not terminated on the becket of a pulley. Instead it is run through another progress capture pulley. This means that an operator can either pull on both ends …
Calculating mechanical advantage: the T-system The subtle but significant difference to this system… a pulley on the load and the main line terminated at head of the tripod. We have a 6:1 mechanical advantage in the pulley system. 1. Assume continuous strands of rope have the same amount of tension. If we start at the …

T Method Applied To Mechanical Advantage Systems Using Rope Grabs. Calculating mechanical advantage: the T-system 1. Assume continuous strands of rope have the same amount of tension. If we start at the point where effort is applied and assume that we apply one unit of tension (1T) then we can assume that the tension along …

Tension forces are two forces acting on one object, moving in opposite directions (away from one another) to stretch the object. Compression forces are two forces acting on one object, moving in opposite directions (towards one another) to compress or deform the object. In this video, the Arizona Vortex is used as a compression member, …

Physics apply to all of our lives. Ropes and rescue and rigging are no different. Pat discusses applied physics of rope rescue, hauling systems and the effects of gravity on raising and lowering objects. Sterling Rope is the Official Rope of Rescue Response Gear’s The Rigging Lab. The Lab uses Sterling’s 11mm HTP Static for …
