Abstract: A slipform paver includes a chassis 2 able to be adjusted in the heightwise direction and having a mounting unit 10 arranged on the chassis for fastening on an arrangement 8 for molding flowable material. The slipform paver is characterised in that the mounting unit 10 for fastening on the concrete mold 8 is mounted on the chassis 2 of the paver to be pivotable on an axis 14 extending in the direction of operation of the slipform paver. To produce parts of a structure whose orientation varies along their length, the concrete mold fastened 8 to the mounting unit is pivoted on the axis of pivot 14 by means of a pivoter unit 15 whereas the chassis of the paver maintains its orientation.

Abstract: The invention relates to a self-propelled civil engineering machine, and in particular to a slipform paver, road paver or road milling machine, and to a method of controlling a self-propelled civil engineering machine. The civil engineering machine according to the invention has a control unit 7 which has means for determining data which defines the position and/or orientation of a reference point R on the civil engineering machine in relation to a reference system (X, Y, Z) independent of the position and orientation of the civil engineering machine. The reference system (X, Y, Z) independent of the machine-related reference system (x, y, z) may be selected as desired, and there is thus no need for the positions of various reference points to be plotted on the ground.

Abstract: A paving system includes a machine having a frame with a plurality of ground-engaging elements coupled with the frame, and a height adjustable screed coupled with the frame. The paving system may also include a paving control system having a receiver configured to receive screed control data indicative of a position of the height adjustable screed relative to a reference position. The paving control system may further include a computer readable memory storing a control algorithm, which may include a smoothness estimating algorithm and a screed adjusting algorithm. An electronic control unit is coupled with the computer readable memory and is configured via the control algorithm to determine a smoothness value for a region of a mat of material which corresponds with an irregular pattern of screed position, in response to screed control data received via the receiver.

Abstract: A device and method for contouring three-dimensionally curved surfaces includes an elongated contouring assembly that is supported at two locations by height adjustment mechanisms that raise and lower the two locations of the contouring assembly independently of each other. The contouring assembly creates a three-dimensionally curved surface as it passes over an area to be contoured. The control of at least one location of the contouring assembly is based on a comparison of the measured position of one portion of the contouring assembly with a profile of the surface to be leveled that is stored in a computer memory. Control of the height of the other location is preferably based on the height above a physical reference measured with a proximity sensor. A pivot or tilting controller may control the tilting of the contouring assembly to follow the slope of the profile stored in computer memory.

Abstract: A lightweight one man screed apparatus to automatically strike off and level uncured concrete flatwork, includes a tri-pod framework beneath which a cutting/leveling member operates. The apparatus is controlled by two grade setting devices, adjustably mounted to the screed tool, which may be adjusted relative to a laser plane generating system. Physical control of the screed member may be provided by at least one screed tool pivotal arm assembly moved for and aft by a carriage operated under the tri-pod framework within a fore and aft footprint. The screed tool is adjusted to grade by being raised or lowered by at least one linear actuators responding to an electronic controller. When moving the framework and screed assembly into freshly poured concrete, an operator is assisted by retractable wheels. The wheels are rotationally stowable or used deployed as part of the tripod/transport system facilitating mobility.

Abstract: A contouring machine control system, contouring/smoothing method, and kit for enabling a contouring machine to automatically contour three-dimensional surfaces includes a contouring member, such as a screed or dirt grading blade, a target either attached to the contouring member or located at a remote location, a tracking device at the other of the contouring member or remote location that tracks the target and measures the position of the target in three dimensions, a proximity sensor adjacent one end of the contouring member to detect its height above a physical reference, and a controller/computer for controlling the height of the two ends of the contouring member. One of the ends is controlled as a function of a stored profile of the desired surface to be contoured and the target or tracking device position, while the second end is controlled as a function of the current height of the proximity sensor above the reference.

Abstract: A drag box for use in applying cold mix asphalt paving material to a surface includes a pugmill for distributing the cold mix over the surface, a strike blade for shearing the asphalt mixture to a desired thickness, cylinders for raising and lowering the strike blade in response to elevational changes in the surface, at least one signal generator associated with each cylinder and adapted to produce a signal indicative of the elevation of the surface, and at least one signal receiver associated with each signal generator. The drag box is pulled behind a prime mover but preferably is not rigidly coupled with the prime mover. The blade is raised and lowered in response to signals emanating from the generator as the elevation of the surface changes, allowing surface level variations to be evened out while paving.

Abstract: A concrete placing apparatus is provided for placing uncured concrete on a support surface, such as an elevated deck of a building. The apparatus comprises a base unit and a movable support, with a conduit assembly extending therebetween. A supply end of the conduit assembly is positioned at the base unit and is connected to a supply line for uncured concrete or other material, while a dispensing end of the conduit assembly is supported by the movable support and extends outwardly therefrom to dispense uncured concrete or other material through a discharge outlet. The movable support is movable arcuately and/or radially relative to the base unit to dispense the concrete in a generally uniform manner over a targeted area. The apparatus may further include a screeding device at the discharge outlet to grade, level, compact and smooth the concrete as it is placed.
