J. R. Clancy has turned its rigging slide rule tool into a free iPhone app, specifically for installers and users of theatre stage rigging. The new app, iRigging, also makes it easier for riggers to get the equipment data they need for proper installation and operation of manual and motorized rigging. iRigging  delivers information about wire rope, batten loading, arbors, stage ropes, motors, fabrics, fleet angles, and more in English and metric units. It’s easy to install and use from an iPhone or iPod Touch.


Wire rope data include:


Minimum sheave pitch diameter

Quantity of cable clips

Wire turnback for cable clips

Proper torque for cable clip bolts

Cable breaking strength

Nicopress sleeve crimp quantity and manual tool


Other data include:

Allowable fleet angles

Uniform and midpoint batten loading

Arbor capacity

Weight of counterweights

Recommended working loads for equipment

Motor current

Stage ropes

Weight of stage fabrics


The company invites users to provide feedback on possible improvements.
