Operating device for manual manoeuvring of a controllable spray nozzle (20) from an open operation platform (9) which is enclosed by boundary side elements (10, 11, 12), particularly for deicing aircrafts, comprises a swinging arm (15) adapted to swing on a mainly horizontal plane across the upper limitation of the elements (10, 11, 12). At its one end said arm is adapted to pivotal suspension at one of the boundary side elements (10, 11, 12). The swinging arm (15) is concave angular-shaped on the horizontal plane, and the length of the swinging arm (15) is greater than any cross dimension of the operation platform (9) which is enclosed by boundary side elements (10, 11, 12). At its other end, the angular swinging arm (15) is provided with a pivotal bed (19) for the spraying nozzle (20) which is connected with an operating hand grip (21) projecting in the direction along the swinging arm (15). |
