Track bridge interaction plays a decisive role in the design of long railway bridges due to the high braking and acceleration forces that occur and the fact that the continuous rail is attached to the superstructure A fundamental parameter for the calculation of the effects of track bridge interaction is the equivalent longitudinal stiffness of piers and abutments with fixed bearings

Perhaps the biggest advantage of the belt conveyor is that it can convey material for both short and long distances FEECO conveyors can carry material for distances anywhere from 10 to 1500 with a single conveyor Screw conveyors are limited to much shorter distances typically around 30m maximum When Working With an Abrasive Material
