The invention relates to a counterweight balancing device for filming cranes of the type that are mounted on vehicles suitable for carrying same and that are used to film moving images, said crane (1) having a rotating centre (4) form which a counterweight system (2) on one side and a filming camera (3) on the other side oscillate as if on a balance. Said device comprises a pantograph mechanism that enables said counterweight system (2) to be maintained in relation to the ground, in the event of any ascending or descending movement of the arm holding the filming camera (3), as a result of the device being equipped with articulated points (6, 7, 8 and 9), fixed shafts (10 and 11) and shafts (9 and 9') movable in relation to the central shaft of the crane (5), thereby forming said pantograph mechanism.
