A limited rotation slewing ring crane (1) comprises: a pedestal (3), a column (2) rotatively coupled, about a first rotation axis, to the pedestal (3) by a slewing ring rotative coupling (6), and means for limiting the relative rotation of the column (2) with respect to the pedestal (3). The crane (1) further comprises a rotative sensor (10) adapted to measure a rotation angle of the column (2) with respect to the pedestal (3), wherein said rotation sensor (10) comprises:- a tubular body (11) axially extending from the base of the column (2) and rotatively integral with the same;- a stationary body (13) connected to the pedestal (3) and a wheel (14), rotatable with respect to the stationary body (13) about a second rotation axis, which is meshed by the tubular body (11), wherein the second rotation axis of the wheel (14) with respect to the stationary body (13) is offset with respect to the first rotation axis of the column (2) with respect to the pedestal (3);- means for sensing the angular position of the wheel (14) with respect to the stationary body (13).
