  • Publication number: 20210061625
    Abstract: A limited rotation slewing ring crane comprises: a pedestal, a column rotatively coupled, about a first rotation axis, to the pedestal by a slewing ring rotative coupling, and means for limiting the relative rotation of the column with respect to the pedestal. The crane further comprises a rotative sensor adapted to measure a rotation angle of the column with respect to the pedestal, wherein said rotation sensor comprises: a tubular body axially extending from the base of the column and rotatively integral with the same; a stationary body connected to the pedestal and a wheel, rotatable with respect to the stationary body about a second rotation axis, which is meshed by the tubular body, wherein the second rotation axis of the wheel with respect to the stationary body is offset with respect to the first rotation axis of the column with respect to the pedestal; means for sensing the angular position of the wheel with respect to the stationary body.

  • Patent number: 10889473
    Abstract: A load crane main boom of the telescopic type having cylinder-piston groups located inside the main boom tubular sections with reduced dimensions. The load crane main boom minimizes the main boom section thanks to a particular arrangement of the cylinder-piston groups. Each cylinder of each piston-cylinder group is connected to a respective boom section through at least one reinforcing rod extending perpendicular to the main boom axial direction and connected to respective section walls of the main boom. At least first and the second cylinder-piston group rods are further supported by a respective reinforcing plate, which is in turn connected to the respective boom section.

  • Publication number: 20190248630
    Abstract: A load crane (1) main boom (3) comprises: a fixed tubular first boom section (4I), a tubular second boom section (4II) telescopically arranged and movable relative to the first fixed boom section (4I) between a retracted position and an extended position, and at least a tubular third boom section (4III) telescopically arranged and movable relative to the movable second boom section (4II) between a retracted position and an extended position; a hydraulic system (6) comprising: a first cylinder-piston group (7I) axially extending within the main boom (3), integrally connected with the fixed first boom section (4I) and connected to the movable second boom section (4II) so to move the latter relative to the fixed first boom section (4I) under the action of a pressurized working fluid; a second cylinder-piston group (7II) axially extending within the main boom (3), integrally connected with the movable second boom section (4II) and connected to the movable third boom section (4III) so to move the latter relative
