Frankenstein Crane

[sparkycuda]

Wow! That reminds me of inside a Bucyrus-Erie 38B. Fully mechanical, with air operated clutches and brakes, open gears and sheaves. Looks to be quite large - what are approximate dimensions of what you have already? Add an angle-iron boom, flat track pads and ready to go. Will the crawlers also be mechanically driven from the upper works? I remember replacing the center shaft on a mechanical crane was a pain the the a$$!
Keep up the good work.
