Abstract
The present invention relates to a mobile concrete mixing system which substantially comprises: a feeding unit (2); a mixing unit (3); a conveyor belt; and a support structure (5) that embodies a first framework (18) supporting the conveyor belt (4), and a second framework (19) supporting the mixing unit (3). According to the present invention, the first (18) and second (19) frameworks are connected to each other by means of a hinge (22) which allows for the rotation of the first framework (18) about a substantially horizontal axis (X) in relation to the second framework (19). In this manner, a movement of the mixing unit (3) between a transporting position (23) and an operative position (24) is determined. Such a rotation about the axis (X) is obtained by keeping the mixing unit (3) in a horizontal position. In turn, by means of a mechanical actuator (27), the conveyor belt (4) is movable between a shortened condition, in the transporting position (23) of the mixing unit (3), and a lengthened condition, in the operative position (24) of said mixing unit (3).
