1 Hauling Systems

2 What Is a Hauling System? Combination of ropes and hardware assembled to form a mechanical advantage used to move a load from one point to another. Named for the amount of advantage it offers 3:1, 4:1, 9:1

3 Definitions Directional pulley: stationary pulley used to change the direction of pull on a rope Haul cam: camming device that secures the haul line to the load line Soft or hard Haul line: rope used to pull on Load line: obvious…

4 Definitions Mechanical advantage pulley: moving pulley that is attached to the load or haul cam that adds MA Piggyback system: Common name given to a 4:1 MA (it is two 2:1 MA systems piggy backed to each other) Ratchet cam: Holds the load line to keep from losing what you have gained with MA
