SLIPFORM PAVER AND METHOD FOR OPERATING A SLIPFORM PAVER
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.
