SYSTEM AND METHOD FOR PAVER SCREED ENDGATE CONTROL

摘要

A height adjustment system (338) for a paving screed apparatus (414) and a method for adjusting the height of the endgates (226) of a screed system (1 14) are disclosed. In a disclosed system (314), the system (314) includes an endgate (226) coupled to a biasing element, such as a spring (235) or a hydraulic cylinder (371) and rod. The biasing element is coupled to an actuator (240). The actuator (240) is linked to a controller (244). 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 (342) for measuring vertical displacement of the biasing element, pressure or load on the biasing element with respect to the setpoint range.
