Abstract (en)
The crane has main and auxiliary arms (5, 7) controlled by respective hydraulic actuators (6, 9). A distributor has a slide (20) displaced between inactive and active positions. The slide does not allow a connection pipe (18) to connect control pipes (15, 16) in the inactive position. The slide permits the pipe (18) to connect the pipes (15, 16) in the active position. A control unit (21) guides the slide in the active position.
