GREIN
Safety bumbers
Bumpers are normally used as shockproof means of transport and self-propelled machines which may inadvertently run over the staff. Their job is to absorb the shock in case of a crushing incident, and to produce a signal for the immediate arrest of the machines (for example AGV). It consists of a block of foam shaped to the customer's design with embedded sensors. The safety bumper are compliant with EN 13856-3. The mats in combination with PS3 control module can reach the CAT 3 - PL “e” as indicated in the ISO 13849-1 standard.
Safety bumber design is largely based on stopping time the machine. Compression distance has to be greater than the distance travelled after the initial contact. This way the bumber ensures that no personnel damage occur in the case of an accident.
Grein safety bumber features two copper strips that do not contact under normal operation (NO). The control unit monitors any contacts between the strips and gives a stopping signal after collision. The control unit also monitors cable breakage.
