With a capacity of up to 2000 pieces of baggage per hour, strength and resilience are needed. The m06 vertical sorting unit »VSU« is used for the distribution and merging of baggage and general cargo between two or three levels. The belt conveyor incorporated into the »VSU«is lifted and lowered using a lifting system with two steel-reinforced tooth belts. This maintenance-free lifting system has been tried and tested for decades.
