Abstract

A jib boom (100) mechanism having a main boom (A) and the feature of automatic opening and closing fixed by means of contact axis (x1) in a manner the said main boom (A) makes rotation in rotating axis in order to provide enhancement of effect fields of telescopic boom cranes and it is characterized in that it comprises second rotating piston (92) giving initial rotating motion to the said jib boom (100) mechanism, a rotating piston (91) giving the second rotating movement to the said jib boom (100) mechanism and located in the alignment same as the second rotating piston (92), a second rotating piston (92) connected to the said rotating piston (91) by at least a rotating joint (93) in a manner to rotate, a joint (93) located between the said rotating piston (91) and second rotating piston (92) and giving an angular motion at an angle of 0° to 180° to the said rotating piston (91) and the second rotating piston (92) and a locking mechanism (10) ensuring that the jib opens at 180° and fixing in the same alignment with the main boom (A) by means of the said joint (93).
