Anti-Collision Protection for Overhead Cranes via Laser Distance Sensor Time-of-Flight

In the steel industry, overhead cranes are used to transport sheet metal coils. Since there are often several cranes on a shared track, there is a risk of collisions. Laser distance sensors time-of-flight work with a reflector mounted on the opposite crane. They measure the distance between two cranes up to a distance of 100 m and transmit the information to the control system. This enables hazardous distances to be detected and cranes to be slowed down in good time or stopped if they approach too closely.

Laser Distance Sensors Time of Flight

Laser distance sensors Time-of-Flight (ToF) work according to the principle of transit time measurement, which means that they cover large working ranges up to 10,000 mm, so that objects can be reliably detected even at great distances. The ToF sensors are extremely robust against interfering ambient light, which ensures reliable operation.
