The R2000 Class 1 laser sensor helps to avoid these collisions by scanning a 360° area around the sensor, detecting the smallest of objects in its scanning zone and giving a pre-emptive warning during normal operation. The R2000 laser scanner gives protection at up to a 30m distance, allowing plenty of time for the crane to slow down.
In order to give a highly reliable and accurate scan the R2000 gives a gapless 360° measuring angle with extremely small light spot. At a scanning frequency of up to 30 Hz, this gives 54,000 measurements per second.
Depending on the application, the R2000 scanner can be set for either a high resolution to detect small parts or higher speed for faster reaction times. With the 10Hz setting, an angular measurement of 0.071° is achieved for detection of extremely small objects. At a distance of 10m this will give a light spot diameter of 15mm and a step of ~12mm making a gapless detection area. The scan plane is only ±0.05° which enables detection of objects in very tight places. At the same 10m range other scanners could have a light spot of approximately 200mm. For applications where objects may not be so small but speed is more important, the 30Hz setting gives an angular resolution of 0.2°. At a distance of 10m this would still give a light spot of 15mm, but the angular step would be ~35mm.
