Abschnitt 4.6 – Safety technology at the shearing point between transfer car and conveyor

Safety measures are required at the shearing point between transfer car and conveyor to avoid serious injuries. If technical measures as partly described in chapter 7 are not possible for example resilient and soft foam cubes in the signal colour yellow with an edge length of at least 400 x 300 mm can be installed. The height of the foam cube should reach the conveyor level.

PICTURE 5: Dimensions of a foam cubes stack

Care must be taken that the front edge of the foam cube flushes with the front edge of the conveyor. Using laser scanners it is recommended to notch the lower part of the foam cubes by 150 mm to enable a scanning underneath this area.

PICTURE 7: Foam cube with notch

The foam cube belongs to the "indicating safety technology". It signals a hazard zone and is designed to prevent the access into this area.

As damages of these foam cubes by fork-lift trucks are to be expected care must be taken that these foam cubes are protected correspondingly and that damaged foam elements will be exchanged immediately. The application by means of Velcro tapes on the floor or laterally at the conveyor has been proven as a practical solution in order to replace the foam cube quickly after unintentional removal.

The application of the foam cubes does not serve to safeguard the shearing point between transfer car and conveyor but rather to point out to the hazard zone and thus to prevent the employees to stand in this critical area.
