Low and high angle rope rescue Flashcards
environment with a shallow grade that does not require the use of rope systems, but movement would be hazardous or difficult without the aid of a rope
low-angle
natural unaltered level ground
grade
environment in which rescuer must be secured with rope for safety
High-angle
A rigging system using one or more pulleys that move a load in line with the anchor point.
simple mechanical advantage system
series of pulleys contained within a wood or metal frame; used with rope to provide a mechanical advantage for pulling operations
block and tackle
the rate of mechanical advantage a system offers in actuality
actual mechanical advantage
a rigging system using a series of travelling pulleys that move in the same direction
compound mechanical advantage system
a rigging system using a series of pulleys that move in different directions
complex mechanical advantage system
the rate of advantage gained from a system if all friction is removed from the system
theoretical mechanical advantage
technique of sliding or descending down a rope in a controlled manner using a friction device
rappelling
mechanical advantage system designed for lifting a load
raising system
