A limited rotation slewing ring crane may include a pedestal, a column rotatively coupled, about a first rotation axis, to the pedestal by a slewing ring rotative coupling, and stops for limiting the relative rotation of the column with respect to the pedestal. The crane may also include a rotative sensor adapted to measure a rotation angle of the column with respect to the pedestal. The rotation sensor may include a tubular body axially extending from the base of the column, a stationary body connected to the pedestal and a wheel. A second rotation axis of the wheel may be offset with respect to a first rotation axis of the column with respect to the pedestal.
