Back in 2010, we were still using paper load charts for a 250-ton crane in Detroit.

You had to flip through a huge binder in the cab, find the right page for the boom length and radius, and do the math yourself. About five years ago, the company switched all the big rigs to digital load moment indicators. Now the computer shows the exact capacity in real time on a screen, with warnings if you get close. It's way safer, but I kinda miss the feel of those old charts. Anyone else remember the switch and have a story about a close call the old system caught?

Digital charts were basically crane origami.

Honestly @ryanf66, I just kept it super simple and used the basic line chart.
