1976 Skyworker 1044A tower. 50 foot working height tower, mounted on truck frame. No cab. 2 cylinder Wisconsin engine to run bucket and large Quincy air compressor. Air system is pu ped up to bucket to run air tools. Unit also has 2nd hydraulic pump and PTO to run off truck transmission. Pony engine runs great and can run all boom functions now as it sits. Unit was maintained be Aerial Lift of CT. Had new cables, pins and knuckle update done by them, was then only use briefly before truck engine went. Has been garaged entire life of machine. I was going to use, but decided to give it up as I have too many projects. Look at my feedback. I only sell quality, well maintained items.
