Safe reduced speed and continuous flow conveyors
The C standard EN 619:2002 for continuous handling equipment and systems only states speed for cases in which people may travel on the conveyor. These are:
Continuous flow conveyors on which persons may travel:
Floor level: Conveying speed of 0.3 m/s
0.3m above floor level: Conveying speed of 0.15 m/s
Full railings: Conveying speed of 0.5 m/s
VDI 2854 also deals with the issue of safe, reduced speed.
This states that a speed is deemed to be safe
if the person has time to escape from a hazardous event.
