Angular Vector Forces

Angular vector forces occur when ropes are passed through a deviation or a directional pulley. Dependent on the angle created, this can have a multiplying

Pulley Systems

Pulley systems are used to provide us with a mechanical advantage, where the amount of input effort is multiplied to exert greater forces on a

Fall Factors

A fall factor is a simple representation of the severity of a fall. It can be used to evaluate the potential loadings exerted on the

Vector Forces

Vector forces become apparent whenever there is an internal angle greater than 0° between two or more rigging components or anchorage points. For ease of
