Publication number: 20240401286Abstract: A screed assembly for a paving machine includes a screed plate, an end gate, and compression mechanisms. The screed plate paves a material to form a mat on a work surface. The end gate restricts a spread of the material in a lateral direction of the paving machine. The end gate includes a support structure and a floating wall. The support structure includes an engagement portion and the floating wall is slidably disposed relative to the support structure and is configured to be guided along the work surface during the paving operation. Further, each compression mechanism includes at least one compression member disposed in an engaged state with respect to at least one of the engagement portion and the floating wall. An actuation of the compression member moves the floating wall with respect to the screed plate to adjust a clearance between the floating wall and the screed plate.Type: ApplicationFiled: May 30, 2023Publication date: December 5, 2024Applicant: Caterpillar Paving Products Inc.Inventors: Reece Berns, Ryan Todd Thiesse, Toby Frelich

Patent number: 10458076Abstract: A control system for a road paver comprises a camera system configured to generate image data of an environment of the road paver. The control system further comprises a controller electronically connected to the camera system. The controller is configured to receive the image data from the camera system, and to apply an object recognition process on the received image data to identify an edge line serving as a reference line for a mat to be laid by the road paver, and to determine a three dimensional position of the identified edge line. The controller may automatically control the road paver, and may assist an operator to control the road paver based on the identified position of the edge line.Type: GrantFiled: July 24, 2017Date of Patent: October 29, 2019Assignee: Caterpillar Paving Products Inc.Inventors: John Lee Marsolek, Toby Frelich, Kent Hoisington
