摘要： A handling equipment of the swingable arm type comprises a double acting cylinder within whose chamber a main piston is sealingly mounted, which is slidable owing to the selective delivery of fluid under pressure at opposite zones of the chamber, which is connected to a rod associated to the arm with a toggle joint. The equipment comprises a device for controlling the oscillation of the arm, including: a cavity of the rod having a nut screw, a screw member with a threaded shank in engagement with the nut screw, a rotatable head opposite to the rod and not slidably mounted with respect to the cylinder, and means for controlling the rotation of the screw member, associated with its head in order to brake the rotation of the screw member following to an anomalous condition in the feeding of fluid under pressure to the chamber of the cylinder.

摘要： A handling equipment of the swingable lever type comprises a driving double acting cylinder (5) having a chamber (18) in which a main piston (15) is sealingly mounted, which is slidable as a result of the selective delivery of fluid under pressure from opposite zones of the chamber (18) of the cylinder (5). The main piston (15) is connected to a rod (10) having a driving end (10a) which projects from the cylinder (5) and is associated with a movable arm (7). The equipment (1) is provided with a device for dampening the oscillation of the arm (7), which comprises an axial cavity (27) formed in the rod (10) and containing a service fluid. A stem (30) rigidly connected to the cylinder (5) and provided with at least one orifice (31, 31a) for the service fluid is sealingly and slidably mounted in the cavity (27), so that the movement of the rod (10) with respect to the stem (30) is slowed down as a consequence of the flowing of the service fluid through said orifice (31, 31a), if the sliding speed of the main piston (15) inside the cylinder (5) exceeds a threshold speed set by the cross-section of said orifice (31, 31a).
