In my 20+ years, I have done almost every job at crane rental company.
We own and operate cranes from 6 Tons to 1200 Tons:
American made hydraulic truck cranes
American, German and Japan made crawler cranes
American and German all terrain cranes
American made rough terrain cranes
American and German made lattice boom truck cranes (both friction and hydraulic winch cranes)
P.S. For any trolls out there, this thread is to help anyone out that is thinking or is already working in the crane industry. So I reserve the right not to answer any crappy questions!
