Personal Protection System from Linde Material Handling

In narrow-aisle warehouses, maximum performance and height are required in confined spaces. This means every single transport process needs to meet the highest standards. Very narrow-aisle trucks from Linde Material Handling rise to the challenge with ease, moving up to 40 pallets per hour. This is made possible thanks to the trucks’ capacity to lift loads and accelerate at the same time. These diagonal movements enable them to reach top speeds even at a height of several meters.

However, this dynamism does involve some particular risks: the driver’s view is often restricted and obstacles or people are easy to overlook. For this reason, the German standard DIN 15185-2 prescribes special protective measures for people in narrow aisles.

The solution is the Personal Protection System (PPS) from Linde Material Handling. The safety system reliably detects people in narrow aisles and intervenes directly in the driving behavior of the industrial truck if necessary. This prevents accidents, guarantees legal certainty for warehouse operators, and increases productivity when handling goods.

Stay Safe with Laser Scanners

The Personal Protection System offers reliable protection thanks to state-of-the-art laser technology. The front and rear of the trucks are equipped with sophisticated laser scanners that permanently monitor the working environment in both directions. Infrared rays are used to detect people and objects within a radius of up to nine meters.

The multi-level safety concept of the Personal Protection System is based on a safety field and two warning zones that can be individually adapted to the situation in the warehouse. If the very narrow-aisle truck approaches a person, the PPS reduces the speed. If any people are detected in the safety field directly in front of the truck, the truck comes to a halt quickly and safely. This multi-stage safety architecture ensures particularly smooth braking. For additional safety, an acoustic signal can be activated for each warning zone.

Safety—Always and Everywhere

The Personal Protection System also ensures safety outside the rows of shelving—for example, when moving from aisle to aisle or in outdoor areas. If the safety system detects anyone in the path of travel, it automatically reduces the speed of the truck or, if necessary, brings it to a halt. One of the two warning fields can be used for this and individually adjusted to the desired width and length.
