Abstract: The invention relates to a suction excavator having a vehicle chassis, a suction fan, and a dumpable material collection container. The material collection container has a collection chamber and is swivelable about a tilt axis that extends parallel to the vehicle longitudinal axis, between a working position and an emptying position. Furthermore, a filter unit is provided which is situated in a filter chamber in the material collection container and through which suction flow passes. The filter unit is rotatably mounted on a rotational axis that extends parallel to the tilt axis of the material collection container, wherein in an unlocked state, swiveling of the filter unit about the rotational axis is enabled in order to swivel the filter unit out of the filter chamber, at least in sections.

Abstract: The invention relates to a device (07) for receiving and transporting components, in particular pipes or tubes (15), on a vehicle (01). The vehicle (01) carries a container (03) having a container cover (05) that is tiltable about a cover axis (19). A carrier (12) of the device is mountable on the container cover (05). An adjustment drive (22) that can pivot the carrier (12) about a pivot axis (21) between a transport position and a working position is preferably also present. Also provided are a retaining device (13) for accommodating at least one component (15), and a drive unit for moving the retaining device (13) relative to the carrier (12) between an upper holding position and a lower removal position. The invention further relates to a suction excavator (01) having a material collection container (03) that includes such a device for receiving and transporting pipes.

Abstract: A method for controlling the movement of an articulated hose mount having at least n>2 members, wherein a change in angle can be induced between neighboring members with the help of a respective drive includes: a) determining the starting position of the n members with the help of sensors; b) input of a direction vector and a velocity parameter; c) determining a target position, which should be taken by a suction crown, on the free end of the last member; d) determining n angle changes which must be carried out on the n members in order to reach the target position while maintaining the following condition: d.i. the suction crown moves into the target position along a straight path of movement; e) controlling the drives associated with the n members in order to perform the predetermined angle change on the n members; and f) cyclically repeating the aforementioned method steps until the direction vector and/or the velocity parameter are zero.

Abstract: The invention relates to a vehicle comprising a tiltable material collecting container which is suspended in a tilt axle running parallel to the longitudinal axis of the vehicle and a telescoping device. The tilt axle runs in a plane of symmetry of the material collecting container. The frame-side ends of the telescope arms are pivotably attached to the frame in the central plane. At least one rotary drive is arranged on the container-side end of at least one telescope arm (09) to enable a rotation of the material collecting container about the tile axle. At least one pivot drive, which enables pivoting of the telescope arms out of the center plane of the vehicle in both angular directions, is provided.

Abstract: A suction excavator includes a suction hose with a suction opening for pneumatically receiving solid or liquid suction material using a fast-flowing air stream. The suction excavator has a separator for separating the suction material from the air stream, a filter unit for cleaning the air stream, a fan unit for generating the air stream, and a recirculation channel that is connected to the pressure side of the fan unit via a volume-controllable recirculation opening. A volume-controllable secondary air opening allows secondary air from the surroundings to be supplied to the suction side of the fan unit, downstream from the filter unit in the flow direction. The recirculation channel is fluidically coupleable to the suction hose to generate a positive pressure in the recirculation channel to blow out recirculation air through the suction hose.

Abstract: The invention relates to a material collection container of a suction excavator, having a suction connection at its rear end-face wall and a suction flow duct that leads from the suction connection through a collection chamber and a filter unit. The suction connection is positioned at the rear end-face wall in such a way that its cross section is intersected by the plane of symmetry of the material collection container. After passing through the collection chamber, the suction flow is divided into at least two subflows that are conducted in air ducts situated on both sides of the plane of symmetry. The invention further relates to a suction excavator having this type of material collection container.
