The 80-ton Faun (also spelled "Farana / FARANA” in some listings) is a hydraulic mobile crane used in heavy lifting operations on construction, infrastructure, industrial sites, etc. It typically features a telescopic boom, hydraulic outriggers for stabilization, winches (main and auxiliary), and is mounted on a truck or carrier chassis. The "80 ton” rating refers to its maximum rated lifting capacity under ideal conditions.
Such cranes must consider load charts (lifting capacity versus boom length and radius), stability (outrigger spread & ground conditions), and structural design (boom strength, hydraulic systems, counterweights).
