As a result, the maximum transfer speed or the running speeds of the conveyors is limited, since the laxative conveyor can not slow down as desired due to the large inertial mass and can be accelerated. In addition, high speed changes of the conveyor lead to heavy wear and also bring the danger with them, the jerky movements elsewhere cause goods to be lost from the chain pins.
