Abstract (en)

[origin: WO9516630A1] The invention pertains to a hydraulic control device for a loading crane, wherein adjacent control slide valves (11-14) actuated by control levers (21-24) are used to activate various functions of the crane itself as well as various functions of a support device (61, 62) for the truck bearing the crane. Thus, connected downstream of at least a portion of the control slide valves (11-14) are selector valves (1, 2) which, depending on their position, direct the hydraulic fluid coming from the corresponding control slide valves (11, 12) either to the crane or to the support device (61, 62).
