Publication number: 20230399064Abstract: 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.Type: ApplicationFiled: August 24, 2023Publication date: December 14, 2023Applicant: GUNTERT & ZIMMERMAN CONST. DIV., INC.Inventors: Ronald M. Guntert, JR., Gerald L. Dahlinger, Richard Wood Francis

Patent number: 11772723Abstract: A paving machine including a modular frame, a plurality of swing legs pivotable relative to the frame, a jacking column secured to each swing leg, a crawler track, a slew gear drive, and angular position transducers for measuring an angular position between the swing leg and the modular frame, and an angular position of the crawler track relative to the jacking column. Feedback from the transducers facilitates maintaining position of the crawler track. The jacking column can include telescoping outer and inner tubes, a vertically oriented hydraulic actuator including a cylinder and a piston operable within the outer and inner tubes, and spaced apart axial bearings coupled to the outer tube and/or the inner tube. The slew gear drive can be secured between the inner tube and a yoke and capable of steering the crawler track under load without lifting the crawler track.Type: GrantFiled: August 9, 2022Date of Patent: October 3, 2023Assignee: GUNTERT & ZIMMERMAN CONST.

Patent number: 11535318Abstract: A swing leg assembly, coupled to a paving machine for spreading, leveling and finishing concrete, includes a pivotable swing leg coupled to the paving machine. The swing leg may pivot between multiple angular orientations relative to the paving machine. A jacking column is coupled to the swing leg, and a crawler track is coupled to the jacking column. A slew drive coupled to the jacking column and crawler track rotates the crawler track relative to the jacking column between multiple angular orientations. A processor using sensors determines the angular positions of the swing leg and crawler track, and in response to determining a change in angular orientation of the swing leg controls the slew drive to cause the crawler track to rotate relative to the jacking column.Type: GrantFiled: March 16, 2020Date of Patent: December 27, 2022Assignee: Guntert & Zimmerman Const. Div., Inc.Inventors: Ronald M. Guntert, Jr., Gerald L. Dahlinger, Richard Wood Francis

Patent number: 11193244Abstract: A paver for laying down a strip of concrete and, with a dowel bar inserter module as part of the paver, inserting dowel bars into and parallel with to the concrete strip. The dowel bar inserter module has an operational width capable of covering paved concrete strips of greater than 34 feet. In some implementations, the dowel bar inserter module has an operational width of 36 feet, 40 feet, or 50 feet.Type: GrantFiled: August 10, 2020Date of Patent: December 7, 2021Assignee: Guntert & Zimmerman Const.

Patent number: 11186958Abstract: A material placer having an augmented hopper, which can receive and convey concrete or other material at a greater rate than other material placers known in the industry. The augmented hopper has a relatively large volume, a bumper structure, a hinged flop gate, and a sliding gate plate that improves the process of receiving concrete or other discharged material from delivery trucks. The hinged flop gate and/or the sliding plate can optionally be vibrated to aid in moving concrete or other material into the trough of the augmented hopper. The material placer is further configured to have ease of access for cleaning and maintenance.Type: GrantFiled: August 31, 2020Date of Patent: November 30, 2021Assignee: Guntert & Zimmerman Const.
