Area guarding at transfer shuttles

The increasing automation of machinery and systems places growing demands on the necessary safety concepts. Classic concepts, such as muting, are often pushed to their limits here. Our innovative safety solutions guarantee gapless safety, efficient material flow and high availability of your system, even with automated processes.

The transportation path of the transfer shuttle is to be monitored for the presence of persons by using safety laser scanners. To ensure optimal use of the floor space available, the shuttle has to move up to close to the wall. For this purpose, the protective field of the safety laser scanner must gradually be reduced as the skate approaches the wall.


An area guarding system with a safety laser scanner is installed on both direction of the shuttle. The autonomous system detects when the shuttle is approaching the adjacent wall, and automatically reduces the size of the protective field of the safety laser scanner.

Advantages for you

  • Improvement of the safety concept across the entire travel range of the transfer shuttle without any reduction in shuttle system performance
  • The autonomous safety systems can each be easily integrated into the shuttle system control via a two-channel safety output
  • Easily retrofittable, minimal mechanical installation requirements
  • Also for the operation of 2 shuttles in one aisle
