My Cousin and I have recently restored a 1978 Bucyrus Erie H-3 Hydrocrane on a 1978 Ford F-700 Chassis.  The Project Lasted about a year ( working in our spare time) It was bought new by Duke Power Company in Charlotte, NC from E.F Craven Company. It was bought at Auction in 1986 By a local Contractor who used it for lifting tasks untill 2011. The machine had become ran down and tired. but its last  job was lifting Jaw plates out of a 32x42 Jaw crusher in the Fall of 2011. I have put  some pictures  in New photos of Old Equipment.
