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 System Five
• The Slope Sensor is attached to the paver’s transverse beam
 Transverse beam is an optional part of the paver

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

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

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

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

Slope Control Theory
Rear Mounted Transverse Beam
• Super-elevations or desired changes in slope
 Sensor has direct feedback of screed position
 Accurate control of desired slope

Front Mounted Transverse Beam
• The slope sensor does NOT move as the screed moves
• Any forces acting on the screed are NOT measured

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)

Screed Extensions
Slope of screed Extensions are controlled manually
• Slope sensor on transverse beam does not measure extensions
