A remote control system includes a mobile terminal configured to control a construction machine in a first operating mode using one or more control elements of the mobile terminal and to control at least one imaging device in a second operating mode using the one or more control elements of the mobile terminal. The at least one imaging device is controllable by the one or more control elements of the mobile terminal to record an environment of the construction machine and/or a working tool of the construction machine. A position and/or alignment of the at least one imaging device is controllable via the one or more control elements of the mobile terminal.

Remote control system for a construction machine and method for controlling a construction machine

A large manipulator includes a chassis, a mast pedestal, an articulated mast, and a control unit. The mast pedestal is rotatable around a vertical axis by means of a rotary drive and arranged on the chassis. The articulated mast includes two or more mast arms pivotally-movably connected, via articulated joints, with the respectively adjacent mast pedestal or other mast arm by a pivot drive. The control unit is configured to actuate the pivot drive and/or the rotary drive to move the articulated mast with a control sequence from an initial position of the articulated mast, autonomously, into a pre-specified target position of the articulated mast.

Large manipulator with automated mast set-up

A device includes a remote control apparatus with a control lever that is pivotably mounted to the remote control apparatus. The control lever is pivotable within an inner zero-position range, an outer travel range, and an oscillation damping range located between the inner zero-position range and the outer travel range. The remote control apparatus is configured to cause movement of a large manipulator, which has an active oscillation damping mode, switch on the active oscillation damping mode and cause movement of the large manipulator when the control lever is within the outer travel range, switch off the active oscillation damping mode when the control lever is located in the zero-position range, and switch on the active oscillation damping mode without causing movement of the large manipulator when the control lever is located within the oscillation damping range.

A manipulator includes an articulated boom configured to be folded out. The articulated boom includes a turntable that can be rotated about a vertical axis, a plurality of boom segments, electrically-actuated proportional valves, and a remote control. The boom segments are pivotable via respective drive assemblies. The electrically-actuated proportional valves are respectively arranged directly on or in proximity to the respective drive assemblies to be controlled. The remote control includes at least one control lever configured to be displaced in a plurality of actuating directions. The manipulator further includes an electronic controller configured to actuate the drive assemblies via a travel command. The travel command indicates a desired movement of the boom tip. The travel command is generated in response to displacement of the control lever into at least one of the plurality of actuating directions. And, the travel command causes actuation of the respective electrically-actuated proportional valves.

Large manipulator with decentralized hydraulic system

A large manipulator includes a chassis, a turntable arranged on the chassis and rotatable around a vertical axis via a rotary drive, and an articulated mast including two or more mast segments pivotably-movably connected, via articulated joints, with the respectively adjacent turntable or mast segment via a respective drive. The large manipulator further includes a mast sensor system configured to detect position of at least one point of the articulated mast or a pivot angle of at least one articulated joint and configured to generate sensor output signals. The large manipulator further includes a control device configured to actuate the drive in a normal operation for mast movement and to limit speed of movement of the articulated mast depending upon the sensor output signals. The drive is manually controllable in an emergency operation. The large manipulator further includes at least one limiting means, which, in the emergency operation, limit speed of the drive to a pre-specified maximum value.

Large manipulator having an articulated mast that can be quickly folded and unfolded

A large manipulator including an extendable folding boom. The extendable boom includes a turntable that is rotatable about a vertical axis and boom segments pivotable at folding joints about folding axes in relation to an adjacent boom segment or the turntable via respective drive assemblies. The extendable boom further includes rotary angle sensors configured to detect folding angles between adjacent boom segments or between one of the boom segments and the adjacent turntable. The extendable boom further includes an inclination sensor arranged at a last of the boom segments forming a boom tip and a computing unit configured to establish an elastic deformation of the extendable folding boom based on the detected folding angles and the inclination of the last boom segment.

An electrohydraulic control circuit includes a hydraulically-operated drive assembly and an emergency valve. The hydraulically-operated drive assembly includes an electrically-actuated proportional valve and hydraulic operating lines. The proportional valve is connected to the hydraulic operating lines for actuation of the drive assembly in a normal operation mode. The proportional valve is also connected to a pressure supply line and to a return line. The emergency valve is connected to the hydraulic operating lines for actuation of the drive assembly in an emergency operation mode. In the emergency operation mode, the emergency valve is actuated via an emergency operating unit.
