Hokuyos UXM series offers

  • Hokuyo UXM-30LAH-EWA and

  • Hokuyo UXM-30LXH-EWA

The difference in the two is mentione din our blog here

Hokuyo UXM have the highest range of the Hokuyo Laser Range Finders. The LAH-EWA has an enhanced resolution.

The UXM-30LAH series accurately detects objects when they move into and out of pre-configured zones. Typically these outputs are used for "Warning", "Slowdown" and "Stop".
Application examples

  •     Obstacle detection of RTGs, RGMs, and container AGVs

  •     Area monitoring to prevent collision between crane booms and ships.

Collision avoidance for RTGs, RGMs and AGVs

The RTG can be slowed down or stopped based on output status retrievd from the sensor.

Area monitoring between crane booms and ships

It is possibel to detect the distance between the crane boom and the ships to prevent collision.
