DG Industrial uses a 14 ton Palfinger unloader (Knuckle Boom) crane with 47’6” of fully hydraulic boom and an additional 20’ of manual boom. The crane is mounted on a 1997 Western Star tractor with a 5th wheel so we can haul equipment to where you need it and offload it or install if you require. This style of crane works really well inside buildings where there is limited headroom for hoisting. A knuckle boom has horizontal extensions that enable it to reach longer distances at lower overall height A common application for this type of crane would be installing overhead cranes inside buildings.
