Mara - Laser Levelers

Catalogue

Levelling machine for construction

Mara Laser is a business activity that for 30 years and more has been analyzing, making and marketing laser and GPS controlled laser levelling machines, turning towards buyers in about 30 nations all over the world.
Thanks to GPS and laser control technologies, we can reach considerable results in different sectors of use: from agricultural soil to sportsground, from building constructions to road excavations, from landscaping to ground scraping.
Mara’s levellers ensure a series of returns and high capacity in more than one situations: from the machine running speed regime, to a total trustworthiness and assurance of the result.

Mara’s technology

The technology used by Mara is what makes it unbeatable, and the results acquired all over the world witness this. Laser and GPS system technologies give an unique performance, mostly when they are used together.

Laser technology

Laser technology is applied to the levellers in a way that continually synchronize the height of the blade.
The laser levelling machine, the laser beam transmitter and the laser beam receiver are the elements of the laser control system for levelling.
The transmitter is positioned on a tripod that examines the natural gradient of the land and sends the signal to the receiver, which is instead positioned on the machine itself.
The laser beam, beacuse of its own characteristics, permits very high preciseness even over long land portions. After obtaining the signal, a technologically perfectioned rotating pentaprism, positioned on these machines, returns an ideal planning for the leveller to follow while running.
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 low or it goes through interference.
On the laser levelling machine, also, there is a control system to annul external interference. It cuts wind sound, automatically reaches the signal and sets the power of the tractor.

GPS system technology

GPS technology, however, is used to settle the position of the laser levelling machine 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 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 obtained, even though this technology offers minor accuracy than laser technology: GPS systems are subject to fluctuations beacuse of the periodic change of constellation of the satellites.
In any case, the minor 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 tough land.
The higher preciseness of the laser signal lays out 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 elasticity of the levellers made by Mara Laser assure their use in more than one areas:

  • Laser levelling machines for agriculture:
    Mara’s laser levellers, among the different conveniences assure a important increase of the arable parts. They enable a reduction in the amount of water used, an increased production, a considerable reduction of chemicals used, as well as seeds. The lowering in work hours, furthermore, 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 conveniences that make these machines incomparable 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 hours, lower costs and greater preciseness in creating the horizontal plan and gradient, are attained.
  • Laser levelling machine for sportsground:
    this type of technology can be utilized very well in this field as it makes possible to level even existing sectors, repairing soil depressions without replacing the lawn.
  • Laser levelling machines for greenhouses:
    thanks to the preciseness, reduced 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 gradient and also a fabulous aesthetic result are ensured.
  • Laser grader machines for roads:
    in this field, important results are attained 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 necessary, on top to the fact that the use of fine materials is reduced.
