Typical Types of Manual Rigging
Single Purchase Systems: A manual rigging system where the pipe battens travels the same distance as the counterweight arbor. In a single purchase system the counterweight should be equal to the weight supported on the pipe batten. Every foot of travel in the counterweight arbor and control line equals a foot of travel at the pipe batten.
Double Purchase Systems: A type of manual rigging system designed for a building with a limited operating gallery height. In a double purchase system the counterweight arbor only travels half the distance of the onstage load. With this system the amount of weight located in the counterweight arbor is double the weight of the onstage suspended load, typically resulting in longer arbors. For every foot of travel in the counterweight arbor the control line and the pipe batten will travel 2'.
