Laser levelling machine for construction

Mara Laser is a business company that for over 30 years has been analyzing, making and marketing laser and GPS controlled laser levellers, turning towards clients in about 30 states all over the world.
Thanks to GPS and laser control technologies, we can reach important results in many areas of utility: from agricoltural ground 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 affidability and certainty of the result.

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 unique 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 observes the natural gradient of the soil and sends the signal to the receiver, which is instead mounted on the machine itself.
The laser beam, beacuse of its internal characteristics, enables very high accuracy even over long sections of land. After getting the signal, a technologically perfectioned rotating pentaprism, mounted on these machines, gives back an ideal planning 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, manufactured by Mara Laser, guarantee the levellers will be able to work on any type fo ground and receive the 360° signal, even if it could be poor or experiences interference.
On the leveller, also, there is a control system to annul external interference. It cuts wind rumble, automatically reaches the signal and sets the power of the tractor.

GPS receiver 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, get the laser signal from the satellites: even in this situation the planning is represented by the signal and reproduced on the soil.
Lately, thanks to technological advancement 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 accuracy is compensated by the wide elasticity of use, mostly when this technology is used to work on large land portions with more than one inclinations, such as agricoltural ground and building constructions.

Integrated laser + GPS system

Mara Laser has created and manufactured an integrated system that adds the precision of laser technology with the potential of GPS, perfect for harsh soil.
The higher accuracy of the laser signal represents the plan within a radius of 1300 meters, while the GPS system communicates the location of the leveller. Hence, the Mara system can settle the height of the tractor leveller and the location of the blade itself.
The creation of the 3D map of the soil enables to highlight the land portions that has to be scraped, the loading areas, the section where to begin, and the best route that allows to make the best work possible, with both the tractor and the leveller in the right position.
Hence, the operator will have instant instructions through the constant updating of the data by the system.

Fields of application

The important accuracy and elasticity of the levellers manufactured by Mara Laser secure their use in more than one fields:

  • Laser levelling machines for agriculture:
    Mara’s laser levellers, among the many plus secure a key increase of the arable land portions. They enable a reduction in the amount of water used, an increased production, a less use of chemicals, as well as seeds. The lowering in work hours, 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 reduced deflections (max 4 mm) and to annul cavities and gaps that would, later, be filled with concrete. The lowering of work hours and the possibility of obtaining an absolute perfect inclinatoin for water to flow down, are other plus that make these machines worthy and priceless in this fields.
  • Laser levelling machines for earth-moving:
    the first-rate performance of the Mara levellers enables to move large quantity of soil very quickly and with low power. In this way, shorter work hours, lower costs and greater accuracy in creating the horizontal plan and gradient, are reached.
  • 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 slope 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 feasible to work for the maintenance of green spaces. In this way, the right gradient and also a great aesthetic result are assured.
  • Laser grader machines for roads:
    in this field, important results are reached thanks to the skills of the Mara’s laser graders to perform the same job as the motor grader, with less costs and more convenient times. In addition, there are key plus, for example specialized labor is no longer needed, besides to the fact that the use of fine materials is reduced.
