  • Patent number: 9873990
    Abstract: A monitoring system for a paving machine having a screed may include an input device configured to receive a first input from an operator of the paving machine, the first input being indicative of a height of the screed above a work surface, and a controller electronically connected to the input device. The controller may be configured to determine an amount of a material deposited by the paving machine based on the first input, receive a signal indicative of an amount of a material delivered to the paving machine, and determine a correction factor based on the amount of the material deposited by the paving machine and the amount of the material delivered to the paving machine.
    Type: Grant
    Filed: July 30, 2015
    Date of Patent: January 23, 2018

  • Patent number: 9151003
    Abstract: A system and method for controlling operation of an endgate of a screed paving machine using a control device is disclosed. The at least one control device may have a plurality of endgate controls and may be employed for issuing commands to a controller by an operator for controlling operation of the at least one endgate and operate the at least one endgate in an up mode and a down mode, changing the fore/aft pitch of the at least one endgate in tilt-up and tilt-down modes and operating the at least one endgate in auto-on and auto-off modes.

  • Patent number: 8825312
    Abstract: A height adjustment system for a paving screed apparatus and a method for adjusting the height of the endgates of a screed system are disclosed. In a disclosed system, the system includes an endgate coupled to a biasing element, such as a spring or a hydraulic cylinder and rod. The biasing element is coupled to an actuator. The actuator is linked to a controller. The biasing element is moveable between a compressed position and an extended position with a setpoint range disposed between the compressed and extended positions. The biasing element is also associated with a sensor for measuring vertical displacement of the biasing element, pressure or load on the biasing element with respect to the setpoint range.
