Abstract: A device is provided for monitoring the compaction of concrete introduced into a slipform of a slipform paver by means of at least one concrete compacting device that has an asynchronous motor for driving an unbalanced mass which generates vibrations. The monitoring device comprises an apparatus for monitoring the stator current of the asynchronous motor, the apparatus being configured such that a change in the compaction of the concrete is determined based on an analysis of the stator current. The apparatus for monitoring the stator current of the asynchronous motor is preferably configured such that the amplitude spectrum of the stator current is determined in order to analyse the stator current. It is advantageous that the compaction of the concrete is not monitored using sensors which are exposed to harsh ambient conditions during operation of the slipform paver.

Abstract: The invention relates to a slipform paver and a method for operating a slipform paver. The slipform paver 1 according to the invention comprises a machine frame 3 carried by rolling assemblies 7, 8, 10, 11, at least two of said rolling assemblies being drivable and at least one rolling assembly being steerable, as well as comprising a support 17 arranged on the machine frame 3 for a slipform mould 18 and a control unit 21 for controlling the rolling assemblies so as to adjust the velocities of the drivable rolling assemblies and the steering angle of the one steerable rolling assembly, or the steering angles of the steerable rolling assemblies. The control unit 21 is configured such that, when the steering angle of the one steerable rolling assembly changes or the steering angles of the steerable rolling assemblies change, the velocities (vLVO, vLHI, vRVO, vRHI ) of the drivable rolling assemblies (7, 8, 10, 11) are adjusted so as to reduce the change in the velocity (vG) at which a reference point (G) referring to the support (17) for the slipform mould (18) will move along a predefined trajectory (T), said change in velocity being caused by changing the steering angle. The quality of the concrete profile produced by the slipform paver is improved as a result.

Abstract: A self-propelled paving machine includes a plurality of swing legs, each swing leg being supported from a ground surface by an associated crawler track steerably connected to an outer end of its associated swing leg. The machine may be re-oriented from a paving mode to a transport mode by driving the ground engaging units to rotate the frame substantially in place on the ground through a re-orientation angle of the frame relative to the ground, and as the frame is rotating, pivoting one or more of the swing legs from a paving position relative to the frame, to a transport position relative to the frame.

Abstract: A self-propelled construction machine includes a plurality of swing legs, each swing leg being supported from a ground surface by an associated crawler track steerably connected to an outer end of its associated swing leg. Pivotal movement of a swing leg may be accomplished by steering the associated crawler track through a non-zero steering angle until the lateral movement of the crawler track achieves the desired pivoting movement of the associated swing leg.

Abstract: The invention relates to a paver, in particular a slipform paver, having a machine frame 1 supported by front and rear undercarriages 2 and 3 and a paving device 6 for the paving of material. The invention relates additionally to a method of operating such a paver. The paver is provided with an apron monitoring device 13 configured to generate elevation profile data or elevation profile signals describing the elevation profile of the material deposited in the apron of the paving device 6 in a direction transverse to the working direction X. In addition, the paver has a data or signal processing device 16 receiving the elevation profile data or elevation profile signals. The apron monitoring device 13 provides the data needed to allow the material to be spread more evenly across the working width of the paver during the feeding operation by means of a spreading device for spreading the material to be paved in a direction transverse to the working direction X and/or to allow the spreading device to be controlled for improved spreading of the material after the paver has been fed.
