    摘要: Solar panels are prepared for installation on an array frame by initially tipping packages of palletized, bundled, vertically-oriented panels in a preparation area to form a vertical stack of horizontally oriented panel separated from the pallet and packaging material for placement on the upper supporting surface of the transport deck. The transport deck is displaced longitudinally alongside a rack of the array frame, together with a lifting machine having a lifting head on a lifting arm for transferring solar panels from a longitudinal row of stacked solar panels on the transport deck to the array frame. The lifting head may be adapted to support one panel from each of the stacks on the transport deck for simultaneous transfer from the transport deck to the array frame.

    摘要: A crane includes a base, an upperstructure rotationally mounted on the base, a boom, and a gantry. The boom is pivotally attached to the upperstructure at a front attachment location and supports a load line operable to raise a payload. The gantry is mounted on the upperstructure and supports a boom line coupled to the boom. The gantry includes at least one front leg mechanically coupled to the front attachment location and inclined away from the boom to apply, to the front attachment location, a horizontal force component towards the boom opposed by a horizontal force component applied by the boom towards the front leg. The upperstructure includes a frustoconical turret forming an upper circle and a lower circle. The front attachment location is aligned over the upper circle of the frustoconical turret.
