A sliding element is slidably constrained to the base frame. An arm capable of moving the loads is hinged to the sliding element. A connection element has a first end hinged to the sliding element, and a second end constrained to the base frame in a mobile manner. Each of a pair of rod elements is hinged to the base frame and to the connection element to form an articulated quadrilateral. A first linear actuator is hinged to the base frame and to the connection element and capable of causing sliding movement of the sliding element relative to the base frame. A second linear actuator is hinged to the sliding element and to the arm capable of causing mutual rotation movement between the arm and the sliding element. ## Claims ### Claim 1 A crane for lifting and transporting loads, comprising: a base frame for transferring loads of the crane onto a support surface by wheels arranged in contact with said surface; a lifting mechanism to lift and transport loads associated with said base frame; a roll-over protection system comprising: a first portion and a second portion of the base frame, mutually hinged to one another and rotating around a hinge, the first portion and the second portion being also constrained by at least one elastic element; and a control system for detecting a mutual position between the first portion and the second portion and of carrying out predetermined tasks of the crane when said mutual position reaches a threshold condition; wherein the deformation of the at least one elastic element is linked to a mutual angular position of the first portion and the second portion; wherein the first portion and the second portion of the base frame are constrained for rotating only around the hinge, wherein said rotating corresponds to a greater or smaller elongation of the elastic element. ### Claim 2 (depends on 1) The crane according to claim 1, comprising at least one sensor for detecting the mutual position between the first portion and the second portion; said at least one sensor being associated with the first portion and/or the second portion. ### Claim 3 (depends on 2) The crane according to claim 2, wherein said at least one sensor is a contact sensor or a proximity sensor. ### Claim 4 (depends on 1) The crane according to claim 1, wherein detection of the mutual position between the first portion and the second portion is carried out by detection of the deformation of the elastic element. ### Claim 5 (depends on 1) The crane according to claim 1, wherein the control system is configured so that, when the mutual position between the first portion and the second portion reaches a threshold condition, every movement of the crane that causes an increase in rolling-over torque is interrupted or inhibited. ### Claim 6 (depends on 1) The crane according to claim 1, wherein the control system is configured so that, when the mutual position between the first portion and the second portion reaches a threshold condition, one or more movements of the crane that cause a decrease in the rolling-over torque are carried out. ### Claim 7 (depends on 1) The crane according to claim 1, wherein, when the mutual position between the first portion and the second portion reaches a threshold condition, an emergency signal perceivable by a user is emitted. ### Claim 8 (depends on 1) The crane according to claim 1, comprising a telescopic arm; wherein when the mutual position reaches a threshold condition, the control system prevents the telescopic arm from extending or moving. ### Claim 9 (depends on 1) The crane according to claim 1, wherein the control system is adapted for detecting the mutual position between the first portion and the second portion as a variation of said mutual position relative to an initial position in which the crane is in a safety condition. ### Claim 10 (depends on 1) The crane according to claim 1, wherein said hinge is located in the lower part of the base frame and said elastic element is located in an upper part of the base frame. ### Claim 11 (depends on 1) The crane according to claim 1, wherein said elastic element is connected to the first portion and to the second portion of said base frame. ### Claim 12 (depends on 11) The crane according to claim 11, comprising a pair of elastic elements, each connected to the first portion and to the second portion of said base frame.
