Mara - Laser Levelers

Catalogue

Used graders for tractors

Mara Laser is a business activity that for 30 years and more has been examining, producing and trading laser and GPS controlled levellers, turning towards buyers in about 30 states all over the world.
Thanks to GPS and laser control technologies, it is feasible to achieve outstanding results in different areas of use: from agricultural soil to sport courts, from building constructions to road excavations, from landscaping to soil scraping.
Mara’s levellers ensure a series of returns and high capacity in more than one situations: from the machine running velocity, to a total trustworthiness and guarantee of the final success.

Mara’s technology

The technology used by Mara is what makes it unique, and the results obtained all over the world testify this. Laser and GPS receiver technologies give an unrivaled performance, mostly when they are used together.

Laser technology

Laser technology is applied to the levellers in a way that without stopping synchronize the height of the blade.
The leveller, the laser beam transmitter and the laser beam receiver are the elements of the laser control system for levelling.
The transmitter is placed on a tripod that examines the natural inclination of the soil and sends the signal to the receiver, which is instead put on the machine itself.
The laser beam, beacuse of its own characteristics, permits very high preciseness even over long sections of land. After picking up the signal, a technologically perfectioned rotating pentaprism, put on these machines, gives back an ideal program for the leveller to follow while running.
The receiver also has an important role, because it correctly reads the laser light received from the transmitter, through special photodiodes. The receivers, made by Mara Laser, guarantee the levellers will be able to work on any kind of ground and receive the 360° signal, even if it could be poor or it is subjected to interference.
On the leveller, moreover, there is a control system to annul external interference. It decreases wind rumble, automatically reaches the signal and sets the power of the tractor.

GPS receiver technology

GPS technology, however, is used to regulate the position of the leveller and the height of the blade.
The levellers, that adopt this technology, perceive the laser signal from the satellites: even in this situation the program is represented by the signal and reproduced on the soil.
Lately, thanks to technological progress and the use of dedicated software, an accuracy of ± 10 mm has been obtained, even though this technology offers less accuracy than laser technology: GPS systems are subject to fluctuations beacuse of the periodic change of constellation of the satellites.
In any case, the less preciseness is compensated by the wide elasticity of use, mostly when this technology is used to work on large parts with more than one inclinations, such as agricultural soil and building constructions.

Integrated laser + GPS system

Mara Laser has produced and made an integrated system that adds the precision of laser technology with the potential of GPS, perfect for harsh soil.
The higher preciseness of the laser signal lays out the plan within a radius of 1300 meters, while the GPS system communicates the location of the leveller. Therefor, the Mara system can regulate the height of the tractor leveller and the location of the blade itself.
The creation of the 3D map of the soil permits to highlight the parts that has to be scraped, the loading areas, the point where to start, and the best way that enables to do the greatest job possible, with both the tractor and the leveller in the right position.
Therefor, the operator will have immediate instructions through the constant updating of the data by the system.

Fields of application

The outstanding preciseness and elasticity of the levellers made by Mara Laser assure their use in more than one fields:

  • Laser levelling machines for agriculture:
    Mara’s laser levellers, among the different benefits assure a important increase of the arable parts. They enable a reduction in the amount of water used, they can provide more abundant harvest, a less use of chemicals, as well as seeds. The decrease in work hours, furthermore, makes the use of these machines a sure investment.
  • Laser levelling machines for construction:
    Mara Laser provides an absolute perfect precision to obtain ground floors with very reduced deflections (max 4 mm) and to annul cavities and gaps that would, afterwords, be filled with concrete. The decrease of work hours and the possibility of obtaining an absolute perfect inclinatoin for water to flow down, are other benefits that make these machines incomparable and incomparable in this fields.
  • Laser levelling machines for earth-moving:
    the superbe performance of the Mara levellers permits to move large amount of soil very quickly and with low power. In this way, shorter work hours, lower costs and greater preciseness in creating the horizontal plan and inclination, are gained.
  • Laser levelling machine for sportsground:
    this type of technology can be used very well in this field as it makes possible to level even existing areas, repairing soil depressions without replacing the lawn.
  • Laser levelling machines for greenhouses:
    thanks to the preciseness, reduced size and easy handling of Mara levellers, it is also feasible to work for the maintenance of green spaces. In this way, the right inclination and also a fabulous aesthetic result are assured.
  • Laser grader machines for roads:
    in this field, important results are gained thanks to the skills of the Mara’s laser graders to provide the same job as the motor grader, with less costs and more convenient times. In addition, there are important benefits, for example specialized labor is no longer needed, on top to the fact that the use of fine materials is reduced.
