Mobile Safeguarding of Automatic Guided Vehicles
For this application, the ROTOSCAN RS4-4 is installed on automatic guided vehicles in
order to monitor the vehicle path. The aim is to detect people or objects in the path of
the vehicle and to automatically bring the vehicle to a halt. Safety systems available up
to now, such as bumpers or safety bars, have allowed only very low driving speeds to
be maintained. In contrast, using the ROTOSCAN RS4-4 as a non-contact “advance
bumper” results in the creation of a substantially larger safety zone.
The vehicles can move faster, and down times are reduced to the necessary minimum.

Protecting Transporter Trolleys against Collisions
Transporter trolleys are generally guided along a system of rails or grooves in the floor.
Hence the vehicle paths are usually just slightly wider than the trolleys themselves. This
represents an increased hazard for people, since it is impossible to get out of the way of
the trolley. For this reason, transporter trolley are used in enclosed areas equipped with
suitable access safeguarding.
