    摘要: A crane comprises a base, a driving body for driving and controlling the crane disposed on the base rotatable in a horizontal plane, an articulated arm attached to the driving body pivotable in a vertical plane, and a clutching means for clutching the construction elements. The arm is folded and extended in a vertical plane. The clutching means is tiltably and detachably connected to a forward end of the arm. The crane further comprises a fixing means tiltably and detachably connected to the forward end of the arm as a substitute for the clutching means. The fixing means is capable of being fixed to the construction, so that the driving body can be moved while the fixing means is fixed to the construction.
