It's always good to have rigging information at your fingertips - it sure beats guessing or digging in your tool box for that chart of numbers. J. R. Clancy has turned its popular rigging slide rule tool into a free iPhone application. Installers and users of theatre stage rigging should find this handy. The new application delivers instant information in English and metric (SI) units.
iRigging provides wire rope data, including: minimum sheave diameter; cable breaking strength; and recommendations for quantity of cable clips, wire turn-back for cable clips, proper torque for cable clip bolts, and Nicopress sleeve crimp quantities. Other data includes: allowable fleet angles, uniform and midpoint batten loading, arbor capacity, weight of counterweights, recommended working loads for equipment, motor current, stage ropes, and weight of stage fabrics.
The tool is free and currently available at Apple App Store.
More information about J. R. Clancy is available at www.jrclancy.com. As of this date there is no information available about the iRigging application on their web site.
Note: The app does not include iCommonSense, so you have to provide that yourself. It does feature standard GIGO* operation, though.
* Garbage-In yields Garbage-Out
Have fun with it, just don’t be an iDiot and drop your iPhone from the iGrid – it might hit someone in the iHead. Has anyone released the iLanyard to keep this from happening?
