BLADE PRO MOTOR GRADER CONTROL SYSTEM GENERAL
SECTION I.
INFORMATION
Chapter 3 is used for operation and maintenance of the Blade Pro Motor Grader Control System used on the
130G Grader with the Tracer Sonic Grade Controller or the R2S-S Laser Receiver with EM2E-24 Electric
Mast flexibility.
EQUIPMENT CHARACTERISTICS, CAPABILITIES, AND FEATURES.
a.
Characteristics.
The Blade Pro Motor Grader Control System automatically controls elevation and/or cross-slope
(1)
of the 130G Grader's cutting edge with an Operator Interface Box. Three essential precision
sensors, read by the Blade Pro Motor Grader Control System, accurately determine the blade's
cross-slope relative to the direction of travel. The Blade Slope Sensor is mounted in the frame
pocket of the rotation circle to determine the blade's slope. The Circle Rotation Sensor is mounted
at the hydra-swivel component to determine the blade's rotation. The Mainfall Slope Sensor is
mounted on right side of Gooseneck Panel of the 130G Grader to measure the slope in the direction
of travel. The blade's actual cross-slope is compared to the desired cross-slope, and is corrected as
needed.
Tracer Sonic Grade Controller uses sonic
(2)
technology to establish an elevation reference
(e.g., a curb and gutter, a string line, a previous
pass, or an existing surface). Once elevation is set,
any elevation deviations are sent to the Remote
Interface Box. The Remote Interface Box provides
correction outputs to hydraulic valve to maintain
relative distance between Tracer Sonic Grade
Controller and reference surface.
