Mara - Laser Levelers

Used grader for roads

Mara Laser is a business company that for 30 years and more has been examining, making and marketing laser and GPS controlled laser levelling machines, turning towards clients in about 30 nations all over the world.
Thanks to GPS and laser control technologies, we can get to outstanding results in many sectors of use: 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 velocity, 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 acquired all over the world witness this. Laser and GPS system technologies provide 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 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 sees the natural inclination of the soil and sends the signal to the receiver, which is instead positioned on the machine itself.
The laser beam, for its internal characteristics, enables very high accuracy even over long land portions. After picking up the signal, a technologically perfectioned rotating pentaprism, positioned on these machines, gives back an ideal program for the leveller to follow while functioning.
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 work on any kind of ground and receive the 360° signal, though it could be low or experiences interference.
On the laser leveller, besides, there is a control system to remove external interference. It cuts wind rumble, automatically reaches the signal and sets the power of the tractor.

GPS system technology

GPS technology, however, is used to regulate 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 program 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 minor accuracy than laser technology: GPS systems are subject to fluctuations for the periodic change of constellation of the satellites.
In any case, the minor accuracy is compensated by the wide elasticity of use, mostly when this technology is used to work on large land sections with various inclinations, such as agricultural soil and building constructions.

Integrated laser + GPS system

Mara Laser has created and made an integrated system that adds the precision of laser technology with the potential of GPS, proper for tough soil.
The higher accuracy of the laser signal shows the plan within a radius of 1300 meters, while the GPS system communicates the precise spot of the leveller. Hence, the Mara system can regulate the height of the tractor leveller and the precise spot of the blade itself.
The creation of the 3D map of the soil enables to highlight the land sections that has to be scraped, the loading areas, the starting point, and the best route that enables 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 outstanding accuracy and elasticity of the levellers made by Mara Laser secure their use in various fields:

  • Laser levelling machines for agriculture:
    Mara’s laser levellers, among the many benefits secure a important increase of the arable land sections. They permits 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 lowering 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 contained deflections (max 4 mm) and to remove cavities and gaps that would, later, be filled with concrete. The lowering of work times and the possibility of obtaining a perfect slope for water to flow down, are other benefits that make these machines worthy and priceless in this fields.
  • Laser levelling machines for earth-moving:
    the superbe performance of the Mara levellers enables 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 inclination, are reached.
  • Laser levelling machine for sportsground:
    this type of technology can be utilized very well in this area as it enables to level even existing sectors, repairing slope without replacing the lawn.
  • Laser levelling machines for greenhouses:
    thanks to the accuracy, 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 assured.
  • Laser grader machines for roads:
    in this area, important results are reached 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 benefits, for example specialized labor is no longer needed, besides to the fact that the use of fine materials is reduced.
