A device particularly for moving oscillating supports for hose winding reels, of the type that comprises a bracket (16) that is rigidly coupled to a tank and to which a fork (17) is articulated about a substantially vertical axis, the hose winding reel (12) being coupled to the fork (17) so that it can rotate about a horizontal axis. The device further comprises a double-acting hydraulic actuator (18) that is articulated to the bracket (16) and is connected, by means of a kinematic chain that comprises a lever (19) with lever systems and crank systems, to the rotation shaft (22) of the fork (17). The actuator (18) determines two limit operating configurations for the device: a closed one, with the reel (12) adjacent to the tank, and an open one, with the reel (12) rotated substantially through 180 sexagesimal degrees. The actuator (18), the lever systems and the crank systems are substantially comprised within the longitudinal dimensions of the lever (19) when the device (10) is arranged in the closed configuration. <IMAGE> |
