I just discovered a great rigging calculator that helps you size webbing or wire rope for many pick configurations. Liftall: Products for Better Lifting manufactures lifting components here in Lancaster, PA. It’s hard to keep those Pennsylvania Dutchman down. The schematic for the two leg configuration is shown below.

The calculator also include a Basket hitch for box, Basket hitch for roll (shown below), three leg hitch and 4 leg hitch.

I think it would make a helpful smart phone app, fitting nicely with the ConstructionKnowledge.net Steel Beam Design app, Wood Beam Design app and Steel Shapes app. We’ll see.

We are just getting started on the next batch of apps, so let us know if you have any suggestions that would make your construction life better.

Speaking of phone apps that make your life better, iKamaSutra works for me. Reviewed as “A stylish way to spice up your sex life”, this tastefully done app will certainly get your creative juices flowing. By the way, sorry if you find this last recommendation offensive. It’s not meant to be…just me passing on a good app.
