  • Patent number: 11866893
    Abstract: The invention relates to a self-propelled construction machine, comprising a machine frame supported by a chassis having wheels or crawler tracks. The basic principle of the invention involves determining a variable ? which is characteristic of the milling profile on the basis of a functional relationship between the variable which is characteristic of the milling profile and the advance speed v and/or milling drum rotational speed n. The variable ? which is characteristic of the milling profile is a correction variable for adjusting the height of the milling drum with respect to the surface of the ground.

  • Patent number: 11346062
    Abstract: The invention relates to a planning system and method for operating one or more road milling machines. In that context, material properties of a road are captured and are geographically associated with one or more roads or road segments. Based on the material properties, an expected milling output of a road milling machine is ascertained, in the context of carrying out milling tasks on the road, or an expected wear on the milling tools. An optimized sequence of milling tasks to be carried out is created on the basis of those data. Accordingly, the invention may enable optimized deployment of the one or more road milling machines and of resources necessary for carrying out the road milling tasks. Aspects of the planning system may be remotely implemented for centralized application with respect to each of the road milling machines, or locally implemented for individual road milling machines.

  • Patent number: 10968577
    Abstract: The invention relates to a tool combination consisting of a chisel holder, which can be fastened to a milling drum of a soil tillage machine, and at least one leading and one trailing chisel, which are retained on the chisel holder, wherein the trailing chisel is arranged after the leading chisel, based on a working movement of the tool combination in use in the soil tillage machine, and wherein each chisel has a chisel tip having a cutter. According to the invention the trailing chisel tip of the trailing chisel has, at least in some areas, a greater hardness than the leading chisel tip of the leading chisel. Thus stoppage times of the soil tillage machine for maintenance can be reduced and the loss of chisels can at least be decreased.

  • Patent number: 10968740
    Abstract: The invention relates to an interchangeable chisel holder (40) which can be fixed to a milling drum (15) of a ground-working machine (10), having a forward chisel holder (42) for the interchangeable holding of a forward chisel (20), preferably a round-shaft chisel, and having a rearward chisel (30, 31), which is held on the interchangeable chisel holder (40), wherein, as based on a working movement (76) of the interchangeable chisel holder (40) when used in the ground-working machine (10), the rearward chisel (30, 31) is arranged behind the forward chisel holder (42). In such an interchangeable candleholder (40) provision can be made, according to the invention, for the rearward chisel (30, 31) to be held on the interchangeable chisel holder (40) axially and fixed in the circumferential direction of the chisel holder. Maintenance-induced stoppages of the ground-working machine can thus be reduced and the loss of chisels can at least be lowered.

  • Patent number: 10577036
    Abstract: In a construction machine (1) for working a ground pavement (29), comprising a machine frame (2), no less than one lifting column (14), no less than one travelling device (4, 6) which is connected to the machine frame (2) via the no less than one lifting column (14), where the machine frame (2) is adjustable in height relative to the ground pavement (29) by means of the lifting column (14), where the lifting column (14) comprises a column element (18) and a guiding element (16), where, during height adjustment of the lifting column (14), the column element (18) is guidable into and out of the guiding element (16) in a telescoping fashion, it is specified for the following features to be achieved: that a mount (26) is specified at the column element (18) into which a locking element (24) is insertable in such a fashion that the locking element (24), in the inserted condition, projects, at least in part, vis-à-vis the column element (18).
