Pulley is used to haul up equipment or raise a person in a rescue situation. Some pulleys have
an integrated rope clamp to make certain tasks easier (these are known as progress capture
pulleys) and others allow for movement along a rope or cable for moving loads or evacuating a
person.
Two factors determine a pulley’s efficiency: Sheave size and bearings/bushings. The larger
the sheave diameter, the higher the efficiency. Self-lubricating bushings are efficient but they
must be regularly maintained. Sealed ball bearings are very efficient and do not require any
maintenance.
Remember that when hauling with a pulley you must factor in the resultant load. If you are
hauling up 100 pounds and the rope is turned all of the way back down to the object being lifted,
you are putting 200 pounds of load on the pulley!
