Horizontal Systems and the Gear Used Part 1

Hey All! I wanted to drop in some thoughts about the equipment used when rigging highlines and other horizontal systems for the purposes of work and rescue. Your anchors are the key… the greater the angle between two anchor points, the greater the stress will be on those anchors. It must be the goal of …

Determining Mechanical Advantage using the T-Method with an added Pulley on the Load

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 …

Mechanical Advantage Using the T-Method with a Horizontal System

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 this single strand of rope will be the same throughout. …
