The MikroGrader™ systems have been designed to automate the control of cross-slope and blade elevation during your grading work on any model of grader. The systems have the quickest response, and have mm accurate control of the blade. The standard system will control the cross-slope of the blade using three sensors or as the ultimate solution you can choose to let the machine be guided by measurements from a RTK GPS sensor or a Robotic Total Station.
Benefits:
- Optimises your work accurately and efficiently
- Improves the operating accuracy of your construction equipment meaning less re-work therefore reducing the wear and tear on your machine and reducing fuel costs for your machine
- Increases productivity and reduces the time spent on each job
- One man and his machine can carry out the majority of earth moving jobs without an assistant, day or night
The installation of the MikroGrader™ system can vary depending on your needs, you can choose to let it control either the cross-slope only or the cross-slope and blade elevation.
In order to maximise productivity and make the system as user friendly as possible, the most commonly used functions can be performed using the two multi-switches, which are mounted directly on the existing control handles.
Each multi-switch has three control buttons. Two buttons on the front to raise and lower the value of the cross-slope and blade elevation, and one button on the side that activates the Auto Mode.
The system comprises:
- CB4 Control Box
- JB4 Junction Box including Main Fall Sensor
- RS4 Rotation Sensor
- XIS1 Cross-Slope Sensor
- MS1 Multi-Switch
and either:
or:
- MD2 Machine Detector
- EM1 Electric Mast
Cross-Slope
To control the cross-slope, the MikroGrader™ uses three sensors, a cross-slope sensor mounted on the blade, a rotation sensor mounted in the centre of rotation of the blade and a main fall sensor mounted on the body of the grader.
The sensors continuously monitor the cross-slope of the blade, rotation of the blade and the inclination of the grader itself. This information is sent digitally via the control box to the hydraulic box, which makes the necessary adjustments to the blade, to ensure that the blade always works with the desired cross-slope.
Blade Elevation
To control the blade elevation, the MikroGrader™ uses either a sonic tracker or laser sensor.
Sonic Tracker
The sonic tracker is mounted on the end of the blade and continuously controls the blade elevation in relation to a reference line; this can be a string line, curb, previously graded surface or any other solid surface. The sonic tracker works on the principle of electrostatics, which has proven to be the most successful method of tracking, its yields measurements of unsurpassed accuracy with an internal resolution of 1mm (1/25"). And to compensate for deviation due to changes in air temperature, you have got the choice of two options, either a built-in thermometer or a temperature bail.
Laser Sensor
The laser sensor is mounted on a mast that enables the sensor to receive the laser beam. This system has been developed to work with either one or two laser sensors, if two are used; both the cross-slope and the blade elevation are controlled using a rotation laser for reference yielding mm accuracy.
3D MikroGrader™ System with GPS or Total Station
The MikroGrader™ is developed to work with a 3D Machine Control Total Station or GPS system. When using a 3D Machine Control system, you upload a 3D plan of the construction site on to your computer. On this 3D plan you can set any curving contours required for your grading work. The digital information about your construction site is then transmitted to the MikroGrader™ and forms the basis of both grade and blade elevation. This means that you do not have to worry about following any reference lines or setting cross-slope.
Benefits:
- Increased productivity and accuracy
- Work to a very small margin, reducing material wastage
- Reduced surveying costs, as all the information is supplied on the 3D plan
- Fewer mistakes, due to using the design data direct from the construction site plan, therefore reducing time and costs for correction
