摘要： An improved balanced actuating device for lifting and/or transport apparatuses comprises a supporting frame (3) having support means (4) for an external load (L), guide means (5) associated with the frame (3) for guiding the support means (4) along a predetermined drive direction (X), drive means (6) operating on the support means (4) for moving them along the guide means (5) for a predetermined stroke (c) between a first and a second end position (A, B). The drive means (6) comprise a cylindrical jacket (7) enclosing a first working chamber (8) and housing thereinside a drive cylinder (9) adapted to exert a drive force (Fl) on the support means (4), a compensation cylinder (10) placed externally to the drive cylinder (9) and adapted to exert thereon a compensation force (F2) sufficient to at least partially balance the external load (L), first supply means (11) of the first chamber (8) with at least one pressurized fluid adapted to exert at least part of one of the forces (Fl, F2). The first supply means (11) comprise a reservoir (12) containing predetermined amounts of two different fluids (13, 14) immiscible with each other and having respective menisci (15, 16) into mutual contact relationship, a first fluid (13) being adapted to be supplied into the first working chamber (8), a second fluid (14) being adapted to transmit to the drive cylinder (9), through the first fluid (13), at least part of the compensation force (F2).
