Palfinger makes the crane attachment- used for all kinds of stuff but delivering drywall through windows, over roofs while the operator runs it wirelessly from a belt box it pretty amazing. I have had them fly huge loads of 16’ sheets of 5/8 drywall over multimillion dollar homes and it’s always a pucker up experience but never an issue. Beastly strength with pet your cat control. Amazing stuff and a million miles from my fathers 1968 case hydraulic backhoe arm..
