Hello!
I'm Greenhall. At one time I was a heavy machinery professinal, but I've gone back to school and spend my time reading legal textbooks. To keep my sanity, I use my knowledge from my prior life to create knowledge about heavy machinery such as cranes, railroad equipment, conveyors, blasting cabinets, etc... I find people that have been around heavy machinery for ten+ years, like myself, have a wealth of knowledge that can keep buyers and owners of machinery from making expensive and irresponsible decisions. Education and sharing of knowledge is one of the most important parts of growing and becoming a more valuable person, which is why I've decided to spend time updating articles about machinery on Wikipedia. Please don't hesitate to send a message if something isn't understood, and we can work together to clear it up.
