Abstract: Methods and apparatus for controlling edge slump in newly formed concrete structures formed by a slip form paving machine. An edge height sensor generates an edge height signal corresponding to a height of an edge of the newly formed concrete structure to thereby detect a slumping of the edge of the newly formed concrete structure behind a slip form paver mold. A controller receives the edge height signal, determines whether any slumping of the edge of the newly formed concrete structure exceeds a set slump limit, and automatically controls an actuator assembly at least in part in response to the edge height signal to adjust the height of a lateral edge portion of a mold bottom plate relative to an interior portion of the mold bottom plate and thereby adjust the height of the edge of the newly formed concrete structure.

Abstract: A slip form paving machine includes a slip form mold having a mold width extending transversely to a paving direction. At least one smoothing beam is supported behind the slip form mold for engaging an upper surface of a formed not yet hardened concrete structure to smooth the upper surface, the at least one smoothing beam being configured to oscillate transversely to the paving direction. At least one advance speed sensor is configured to provide an advance speed signal corresponding to an advance speed of the slip form paving machine in the paving direction. A controller is configured to receive the advance speed signal and to generate a command signal to control a frequency of transverse oscillation of the at least one smoothing beam such that a constant relationship is maintained between the advance speed and the frequency of transverse oscillation.

Abstract: A road milling machine includes a machine frame having a longitudinal axis. A plurality of ground engaging units support the machine frame from a ground surface. A milling drum is supported from the machine frame. An operator's station is supported from the machine frame by a support linkage configured to move the operator's station laterally between an inner position and an outer position relative to the machine frame. The support linkage includes at least one pivot link extending between the machine frame and the operator's station and oriented to pivot about a pivot axis extending parallel to the longitudinal axis of the machine frame. The operator's station in the outer position extends laterally partially beyond the machine frame on one of the left and right edges of the machine frame, the outer position being at a higher elevation than the inner position relative to the machine frame.

Abstract: A self-propelled construction machine for working the ground, in particular a stabilizer or recycler, has a controller for automatically reversing the direction of travel, which interacts with the drive device for the wheels or crawler tracks. The controller is configured such that the drive device, after receiving a travel direction reversal control signal, reduces the predefined first speed at which the construction machine travels in the first direction of travel until the construction machine is stationary, and, after the construction machine is stationary, drives the wheels or crawler tracks in the opposite direction, wherein the drive device increases the speed in the second direction of travel up to a predetermined second speed. Not only the drive device, but also other components of the construction machine, may be automatically controlled depending on different driving situations.

Abstract: The present invention relates to an interchangeable unit (28) for material-removing work on a subsoil (U) starting from ground surface (A), the interchangeable unit (28) being designed for operational physical and functional coupling to a machine frame (12) of a road construction machine (10), the interchangeable unit (28) comprising:



a housing (30),
a removal tool (32), which is mounted on the housing (30) so as to be rotatable about a working axis (R) and of which a circumferential section protrudes from a working opening (30c),
a drive belt pulley (62), which is rotatably mounted on the housing (30) and is able to be coupled to a drive belt (58),
a transmission gear unit (76), which transmits torque and rotary motion from the drive belt pulley (62) to the removal tool (32) by reversing the direction of rotation, at least the axis of rotation (P62) of the drive belt pulley (62) running at a distance from the working axis (R).




According to the invention, a working shaft assemblage (74) penetrates a housing wall (30d) of the housing (30), the working shaft assemblage (74) connecting the removal tool (32) with a working gear component (70) situated on the side of the housing wall (30d) facing away from the removal tool (32) for equidirectional joint rotation, the transmission gear unit (76) being situated between the drive belt pulley (62) and the working gear component (70).

Abstract: A system is provided for determining a volume of material milled, or a surface area milled, by a construction machine having a milling drum. The volume of material milled is determined as a function of a cross-sectional area of material to be milled in front of the milling drum and a distance traveled by the construction machine while actively milling. The cross-sectional area is determined in part by direct machine observation of one or more profile characteristics of a ground surface in front of the milling drum. The surface area milled is determined as a function of the width of the area to be milled in front of the milling drum and a distance traveled by the construction machine while actively milling.
