Systems for controlling 3D machines are created to transform digital terrain models into actual terracing. There are a number of requirements that must be met for this to be achievable. Digital data is initially required by the machine operator or an autonomously operated machine.
The conventional grade staking method is essentially disregarded by a 3D machine control system.
A 3D grade control system displays the site plans on a screen in front of the machine operator rather than handing the surveyor the site plans, who uses them to manually set the stakes, and then having the machine operator visually interpret those stakes.
An on-board computer in the machine’s cab has a digital copy of the site plans saved in its memory, and it receives information on the cutting edge of the blade from a machine receiver and other on-board sensors.
After determining how far the cutting edge is from grade, the computer instructs the hydraulics to drive the blade.
The Global 3D machine control system market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
The Niveltronic Plus System for Automated Grade and Slope Control enters the third dimension with Niveltronic Plus 3D. Its 3D data interface enables the use of 3D sensors for grade control in addition to more traditional sensors like sound and mechanical ones. Niveltronic Plus 3D must be connected to an external 3D machine control system in order for this to be accomplished.
The next stage of 3D machine control is represented by Navitronic Basic. It’s capabilities extend beyond standard grade and slope control. In addition to this, Navitronic Basic completely automates the regulation of the screed position.
The location of the screed is accurately regulated by the screed’s extending units in order to provide the highest level of paver precision. Displacement sensors on the extending units measure the screed’s current breadth for this purpose.
The user then has two possibilities for setting position accuracy: he can specify the screed’s extreme left or right end as a fixed reference so that paving happens along this designated line. Alternatively, he can establish a predetermined pave width that will remain in place for the entire project.
The use of many positioning systems from renowned producers like Leica, TopCon, and Trimble is made possible via the open interface. Road pavers can use 3D sensors for grade and slope control thanks to Niveltronic Plus 3D.
For operators and specialists in the construction industry, the improved compatibility between the Leica MC1 3D machine control system and Caterpillar’s NGH sensors offers a number of advantages.
With this technical approach, the Leica MC1 software may operate in harmony with the current Cat Grade 2D Assist system without the need for any further hardware modifications, in contrast to conventional solutions that need for sensor replacements. It leads to a smoother and simpler installation, reducing downtime.
