A crane (10) for lifting and transporting loads, comprising: a base frame (12) to transfer loads onto a support surface by means of a plurality of contact means in contact with said surface; an arm (18) for lifting loads, which is rotatable relative to said base frame (12) around a vertical axis, wherein the angular range of said arm (18) around the vertical axis comprises a plurality of angular fields (A1, A2, A3, A4, A5); a plurality of load sensors (C1, C2, C3, C4), each load sensor (C1, C2, C3, C4) being associated with a respective contact means to detect the force on the support surface; a control system (16) to obtain, from said load sensors (C1, C2, C3, C4), the value of the force, detect the angular field (A1, A2, A3, A4, A5) where said arm (18) is located, determine a danger condition based on the values detected by said load sensors (C1, C2, C3, C4), according to different criteria in at least two different angular fields (A1, A2, A3, A4, A5), carry out predetermined functions of the crane (10), if said danger condition is reached.
