Publication number: 20210325899Abstract: A system includes one or more processors configured to determine a discharge rate associated with discharging material from a hauling machine. In some examples, the system receives sensor data associated with a crushing machine configured to receive the material. Based on the sensor data, the system determines the discharge rate, to optimize the efficiency of the crushing machine. In some examples, the system determines the discharge rate based on input by an operator via a user interface. In some examples, the system determines an angular rate at which to raise a bed of the hauling machine to cause the material to be discharged at the discharge rate. Based on a determination to discharge material, the system causes the bed to be raised at the angular rate to discharge material. In some examples, the system may update the discharge rate based on additional sensor data and/or an additional operator input.Type: ApplicationFiled: April 21, 2020Publication date: October 21, 2021Applicant: Caterpillar Inc.Inventors: Kenneth Franklin Grambihler, James Wilber Landes, Harry Paul Newton, Joseph E.

Patent number: 9365377Abstract: A splicing tape and a method of using such tape to equip a wound roll for flying splice. The tape includes a first and second carrier and two strips of laminating composition disposed between them, each strip joining the first carrier to the second carrier. The carriers have a first and a second layer of pressure-sensitive, laminating composition and a first and a second layer of pressure-sensitive adhesive. The strips of laminating composition are disposed such that they are not in direct contact with one another. They form a predetermined breakage point. The splicing tape is adhered to the roll such that part of the first layer of pressure-sensitive adhesive forms a first bonding area, the end region of the uppermost ply of the wound roll, and the second layer of pressure-sensitive adhesive forms a second bonding area to the roll, which is located partly below the first bonding area.Type: GrantFiled: December 15, 2009Date of Patent: June 14, 2016Assignee: tesa SEInventors: Christoph Nagel, Niels Czerwonatis, Stefan Wulf, Jens Nootbaar

Publication number: 20150298666Abstract: Wheel slippage of a machine may be controlled using brake control and engine torque control. In some examples, the present disclosure describes a method of controlling a wheel. Example methods may include sensing a rotational speed of the wheel, and sensing an acceleration of the machine. The method may also include estimating a target speed of the wheel based at least in part on the rotational speed of the wheel and the acceleration of the machine. The method may continue with calculating a speed error, the speed error being a difference between the rotational speed and the target speed. The method may also include controlling a brake of the wheel based on the speed error and/or a torque of an engine of the machine based on the speed error.Type: ApplicationFiled: April 22, 2014Publication date: October 22, 2015Applicant: Caterpillar Inc.Inventors: Yun Liu, Gerry McCann, Stefan Wulf, Ry Whittington
