Abstract (en)
A driving system of the opening/closing sequence of telescopic stabiliser beams comprising multiple mobile members in a self-propelled machine, and in particular in a concrete pump. During the extension movement of the telescopic beam, the different members (A,B,C) of the same are caused to become temporarily mutually fixed, except one only thereof at a time, sequentially starting from the largest intermediate member (B) down to the terminal resting member (C) and viceversa during the retraction mevement, thanks to a mechanical structure comprising a double cam hook (3) idly pivoted about a vertical wall of each intermediate member (B) and projecting from the two sides of said wall; and a guide and/or grip elements (1,2,7) projecting from the neighbouring corresponding walls of the other members, on which said hooks (3), are apt to slide and/or engage to cause said members to become mutually fixed. Actuation of the telescopic beam can therefore be performed also with a single cylinder/piston assembly, in any case keeping the desired extraction/retraction sequence of the beam members.
