  • Publication number: 20240318388
    Abstract: A system for assisting an asphalt compactor in performing a directional change can include a controller configured to perform a turn-out for the asphalt compactor by steering the asphalt compactor at a desired turning angle on an asphalt mat; the controller configured to turn off a vibratory system for the asphalt compactor during the turn-out; the controller configured to slow down and stop the asphalt compactor after a desired distance into the turn-out; and the controller configured to move the asphalt compactor in an opposite direction and restart the vibratory system.

  • Publication number: 20240295085
    Abstract: The asphalt compactor may include a control system communicatively coupled to the one or more sensors including a grade sensor configured to determine a slope of the asphalt surface within the compacting area in at least the direction of travel of the asphalt compactor, the control system configured to: receive data indicative of the slope of the asphalt surface in at least the direction of travel of the asphalt compactor from the grade sensor, determine if the slope of the asphalt surface is one of an incline slope or a decline slope in the direction of travel, if the slope is determined to be the incline slope, determine if the incline slope exceeds a first threshold for the incline slope, and if the incline slope exceeds the first threshold for the incline slope, control a vibratory system to stop vibration of the trailing drum.

  • Publication number: 20220410803
    Abstract: A compactor machine can include a machine frame; at least one cylindrical roller drum rotatably coupled to the machine frame and rotatable about a drum axis oriented generally transverse to a direction of travel of the compactor machine; a plurality of cameras mounted to the machine frame so as to provide a 360° bird's eye view of an area around the machine; a display showing the 360° bird's eye view; and a controller; wherein, the controller is configured to determine certain conditions regarding a compacting operation of the compactor machine and the controller overlays a highlight symbol on the 360° bird's eye view on the display notifying a machine operator of the certain conditions.

  • Patent number: 8967910
    Abstract: A vibratory compactor includes a roller and an eccentric shaft. The roller is rotatably mounted on a main frame and may include a first vertical support and a second vertical support. The eccentric shaft is rotatably connected between the first vertical support and the second vertical support in the roller. The eccentric shaft includes a first end, a second end, a first eccentric weight, a second eccentric weight, and a center portion, casted as a single piece. The first eccentric weight is proximal to the first end and the second eccentric weight is proximal to the second end. The center portion may be disposed between the first eccentric weight and the second eccentric weight. The center portion may include at least one cavity on a surface of the center portion. The at least one cavity is elongated between the first eccentric weight and the second eccentric weight.
