Paver System Five Slope Sensor Theory of Operation Presentation - Date (change on Slide Master)

Slope Control • Slope Control can be added to any Paver System Five • The Slope Sensor is attached to the paver’s transverse beam ü Transverse beam is an optional part of the paver Presentation - Date (change on Slide Master)

Transverse Beam • Most paver manufacturers provide a rear-mounted transverse beam • Some provide a front mounted transverse beam as “standard” • Rear mounted beam is available if the customer requests it Presentation - Date (change on Slide Master)

Slope Sensor • The electronic level sensor accurately measures slope • The Slope sensor sends the slope measurement to the control box • The control box drives the paver’s tow cylinder up or down until the slope sensor measures the desired slope Presentation - Date (change on Slide Master)

Slope Control Theory • Slope Control is a “slave” to grade control • Grade sensor raises or lowers one tow arm cylinder • The slope sensor measures the change • The control box drives the opposite tow arm cylinder to maintain a constant slope Presentation - Date (change on Slide Master)

Slope Control Theory Rear Mounted Transverse Beam • The slope sensor does move as the screed moves • Any forces acting on the screed are measured and the screed is adjusted Presentation - Date (change on Slide Master)

Slope Control Theory Rear Mounted Transverse Beam • Super-elevations or desired changes in slope ü Sensor has direct feedback of screed position ü Accurate control of desired slope Presentation - Date (change on Slide Master)

Slope Control Theory Front Mounted Transverse Beam • The slope sensor does NOT move as the screed moves • Any forces acting on the screed are NOT measured Presentation - Date (change on Slide Master)

Crown in screed Transverse beam spans tow arms – not directly mounted to the screed • Manual Crown adjustments are not controlled • Slope is controlled across ends of main screed (tow arm attachment points) Presentation - Date (change on Slide Master)

Screed Extensions Slope of screed Extensions are controlled manually • Slope sensor on transverse beam does not measure extensions Presentation - Date (change on Slide Master)
