GPS laser leveller for construction

Mara Laser is a business company that for 30 years and more has been analyzing, producing and marketing laser and GPS controlled laser levelling machines, calling on buyers in about 30 states everywhere in the world.
Thanks to GPS and laser control technologies, it is feasible to achieve considerable results in many areas of utility: from agricultural soil to sportsground, from building constructions to road excavations, from landscaping to soil scraping.
Mara’s levellers ensure a series of advantages and high productivity in various situations: from the machine functioning speed regime, to a total trustworthiness and assurance of the result.

Mara’s technology

The technology used by Mara is what makes it unique, and the results obtained all over the world are proof of this. Laser and GPS system technologies give 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 leveller, the laser beam transmitter and the laser beam receiver are the elements of the laser control system for levelling.
The transmitter is located on a tripod that examines the natural inclination of the land and sends the signal to the receiver, which is instead put on the machine itself.
The laser beam, as it is one of its internal characteristics, permits very high preciseness even over long land portions. After picking up the signal, a technologically perfectioned rotating pentaprism, put on these machines, returns an ideal pianification for the leveller to follow while functioning.
The receiver also has an important role, because it correctly reads the laser light received from the transmitter, through special photodiodes. The receivers, manufactured by Mara Laser, guarantee the levellers will be able to work on any kind of soil and receive the 360° signal, though it could be low or experiences interference.
On the leveller, besides, there is a control system to annul external interference. It lowers wind sound, automatically reaches the signal and settles the power of the tractor.

GPS system technology

GPS technology, after all, is used to settle the position of the leveller and the height of the blade.
The levellers, that adopt this technology, obtain the laser signal from the satellites: even in this situation the pianification is illustrated by the signal and reproduced on the land.
Nowadays, thanks to technological advancement and the use of dedicated software, an accuracy of ± 10 mm has been reached up, even though this technology offers less 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 less preciseness is compensated by the wide adaptability of use, in particular when this technology is used to work on large parts with various inclinations, such as agricultural soil and building constructions.

Integrated laser + GPS system

Mara Laser has produced and manufactured an integrated system that adds the precision of laser technology with the potential of GPS, proper for tough land.
The higher preciseness of the laser signal shows the plan within a radius of 1300 meters, while the GPS system communicates the precise spot of the leveller. Therefor, the Mara system can settle the height of the tractor leveller and the precise spot of the blade itself.
The creation of the 3D map of the land permits to highlight the parts that has to be scraped, the loading areas, the section where to begin, 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 prompt instructions through the constant updating of the data by the system.

Fields of application

The considerable preciseness and adaptability of the levellers manufactured by Mara Laser secure their use in various fields:

  • Laser levelling machines for agriculture:
    Mara’s laser levellers, among the many plus 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 considerable reduction of chemicals used, as well as seeds. The decrease in work times, moreover, makes the use of these machines a sure investment.
  • Laser levelling machines for construction:
    Mara Laser gives an absolute perfect precision to obtain ground floors with very contained deflections (max 4 mm) and to annul cavities and gaps that would, afterwords, be filled with concrete. The decrease of work times and the possibility of obtaining an absolute perfect inclinatoin for water to flow down, are other plus that make these machines priceless and priceless 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 times, lower costs and greater preciseness in creating the horizontal plan and inclination, are achieved.
  • Laser levelling machine for sportsground:
    this type of technology can be utilized very well in this area as it enables to level even existing areas, repairing slope without replacing the lawn.
  • Laser levelling machines for greenhouses:
    thanks to the preciseness, contained size and easy handling of Mara laser levelling machines, it is also doable to work for the maintenance of green spaces. In this way, the right inclination and also a great aesthetic result are ensured.
  • Laser grader machines for roads:
    in this area, important results are achieved thanks to the capability 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 plus, for example specialized labor is no longer needed, besides to the fact that the use of fine materials is reduced.
