GPS laser leveller for earth-moving

Mara Laser is a business company that for over 30 years has been examining, producing and trading laser and GPS controlled laser levellers, calling on clients in about 30 states everywhere in the world.
Thanks to GPS and laser control technologies, we can get to significant results in many areas of use: from agricoltural ground to sport courts, from building constructions to road excavations, from landscaping to soil scraping.
Mara’s levellers ensure a series of advantages and high capacity in more than one situations: from the machine operating speed regime, to a total trustworthiness and guarantee of the final success.

Mara’s technology

The technology used by Mara is what makes it unbeatable, and the results obtained all over the world testify this. Laser and GPS system technologies provide an unique performance, in particular when they are combined.

Laser technology

Laser technology is applied to the levellers in a way that without stopping synchronize the height of the blade.
The laser 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 observes the natural gradient of the soil and communicates the signal to the receiver, which is instead mounted on the machine itself.
The laser beam, as it is one of its internal characteristics, permits very high accuracy even over long sections of land. After obtaining the signal, a technologically perfectioned rotating pentaprism, mounted on these machines, returns an ideal pianification for the leveller to follow while operating.
The receiver also plays a very important part, 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 move on any type fo ground and receive the 360° signal, even if it could be poor or it is subjected to interference.
On the laser leveller, also, there is a control system to remove external interference. It lowers wind sound, automatically captures the signal and sets the power of the tractor.

GPS system technology

GPS technology, after all, is used to set the position of the laser leveller and the height of the blade.
The levellers, that adopt this technology, get the laser signal from the satellites: even in this situation the pianification is illustrated 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 minor accuracy than laser technology: GPS systems are subject to fluctuations as it is one of the periodic change of constellation of the satellites.
In any case, the minor accuracy is compensated by the wide elasticity of use, in particular when this technology is used to work on large parts with more than one inclinations, such as agricoltural ground and building constructions.

Integrated laser + GPS system

Mara Laser has produced and made an integrated system that connects the precision of laser technology with the potential of GPS, proper for harsh soil.
The higher accuracy of the laser signal shows the plan within a radius of 1300 meters, while the GPS system communicates the location of the leveller. Thus, the Mara system can set 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 starting point, and the best way that enables to do the greatest job possible, with both the tractor and the leveller in the right position.
Thus, the operator will have instant instructions through the constant updating of the data by the system.

Fields of application

The significant accuracy and elasticity of the levellers made by Mara Laser secure their use in more than one areas:

  • Laser levelling machines for agriculture:
    Mara’s laser levellers, among the many conveniences secure 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 times, besides, makes the use of these machines a sure investment.
  • Laser levelling machines for construction:
    Mara Laser gives a perfect precision to obtain ground floors with very reduced deflections (max 4 mm) and to remove cavities and gaps that would, afterwords, be filled with concrete. The decrease of work times and the possibility of obtaining a perfect inclinatoin for water to flow down, are other conveniences that make these machines priceless and incomparable in this areas.
  • Laser levelling machines for earth-moving:
    the fine performance of the Mara levellers permits to move large quantity of soil very quickly and with low power. In this way, shorter work times, lower costs and greater accuracy in creating the horizontal plan and gradient, are gained.
  • Laser levelling machine for sportsground:
    this type of technology can be used very well in this field as it enables to level even existing areas, repairing soil depressions without replacing the lawn.
  • Laser levelling machines for greenhouses:
    thanks to the accuracy, reduced size and easy handling of Mara laser levellers, it is also doable to work for the maintenance of green spaces. In this way, the right gradient and also a great aesthetic result are ensured.
  • Laser grader machines for roads:
    in this field, important results are gained thanks to the capacity of the Mara’s laser graders to perform the same job as the motor grader, with minor costs and more convenient times. In addition, there are important conveniences, for example specialized labor is no longer needed, besides to the fact that the use of fine materials is reduced.
