  • Patent number: 10053167
    Abstract: A paving machine for spreading, leveling and finishing concrete having a main frame, center module, bolsters laterally movably, and a crawler track associated with respective aft and forward ends of the bolsters. A bolster swing leg for each crawler track supports an upright jacking column. A worm gear drive permits rotational movements of the crawler track and the jacking column. A hinge bracket is interposed between each swing leg and a surface of the bolsters to enable pivotal movements of the swing leg. A length-adjustable holder engages the pivot pin on the hinge bracket and pivotally engages the swing leg. The holder permits pivotal motions of the swing leg in its length-adjustable configuration and prevents substantially any motion of the swing leg in its fixed-length configuration. A feedback loop cooperates with transducers keeping the crawler tracks position. The paving machine can be reconfigured into a narrowed transport configuration.

  • Patent number: 6923594
    Abstract: A pavement ramp edge maker, paving machine and related method are provided for generating a pavement edge ramp that is equal to or less than approximately 45° relative to a surface upon which the ramp is formed. The edge maker generates a ramp that is partially compacted using a compaction surface that extends upwardly from a bottom edge of an end gate of a paving machine. When the pavement mat is compacted, the resulting ramp has an angle that is equal to or less than approximately 45° relative to a surface upon which the ramp is formed.

  • Patent number: 6890125
    Abstract: A mechanical linkage having a geometry designed to substantially hold the plane of a main screed and the plane of an extension screed at a generally constant relative angle with respect to one another through a predetermined range of screed depth adjustments. The linkage is configured to allow the extension screed to be raised and lowered by an amount sufficient to compensate for angle of attack and elevation changes in the main screed. In particular, the linkage compensates for the effect of the radial distance differences from the axis of rotation of tow bars of the main screed and extension screed as the main screed pivots with respect to the tow point of the tow bars for different asphalt mat depths. An alternate embodiment includes actuators, together with sensors, for sensing the position of the extension screed with respect to the main screed and automatically compensating for changes in main screed position to properly orient the extension screed with respect to the main screed.

  • Patent number: 6520716
    Abstract: The invention relates to a paving screed for a paver, with a basic screed and with at least one lateral extendable screed part which is connected to the basic screed via hydraulically actuable tensioners. The height of the extendable screed part can be adjusted via a height setting device which comprises vertical spindles which are coupled to the extendable screed part and are held on the basic screed rotatably relative to the latter. The spindles are adjustable via a common drive motor, it being possible, as a result of the actuation of the drive motor, to trigger a release of the hydraulically actuable tensioners for the duration of actuation. The extendable screed part is also connected to the basic screed via spring-biased screws.

  • Patent number: 6390728
    Abstract: A concrete paving machine for leveling concrete having a frame and at least one dowel apparatus carried by the frame. The at least one dowel apparatus is movable along a working width of the concrete paving machine in a direction perpendicular to a paving path. The at least one dowel apparatus includes a vibration device and a dowel distribution device. The dowel distribution device comprises a series of longitudinal members having L-shaped profiles. Each longitudinal member forms a predetermined pattern of recesses wherein the series of longitudinal members are slidably arranged so that in an unlocked position, the recesses of each longitudinal member are aligned so as to permit distribution of at least one set of dowel bars. In a locked position, each longitudinal member is arranged to so that the recesses are misaligned so as to prevent distribution of at least one set of dowel bars.

  • Publication number: 20020044831
    Abstract: The invention teaches a slip form paving machine which can be used for both zero clearance variable width and variable width conventional paving using the same paving pan. The main frame of the machine is designed to hydraulically extend and retract from varying desired widths. The paving assembly, attached to the main tractor assembly frame, is adjustable as wide as the width of the main frame of the machine or further past the exterior limits for additional clearance, if required. The paving pan, which is part of the pan assembly, can also be extended to conform to these various widths. In a “zero clearance” paving mode, the same pan is located behind the main tractor frame, whereas in conventional paving, the pan is located under the center of the main frame inside of the tracks. In addition, the paving pan can be adjusted to pave varying surface angles, if required.

  • Patent number: 6273636
    Abstract: An edge-forming device is used with a screed assembly having lateral ends and a screed plate extending between the lateral ends, the screed plate having a generally horizontal working surface, and a generally horizontal centerline. The edge-forming device includes a frame connected with a lateral end of the screed assembly and a plate disposed below the frame. The plate has a horizontal working surface and extends outwardly beyond the screed assembly lateral end. An adjustment mechanism is connected with the frame and with the edge-forming plate and displaces the plate with respect to the frame to adjust a vertical position of the edge-forming plate with respect to the screed plate such that the plate forms a vertical step in a mat of material paved by the screed assembly proximal to an edge of the mat. The adjustment mechanism also pivots the plate to adjust the taper angle of the vertical step in the mat and also to adjust the angle of attack of the plate.
