bridge

A serious problem in the operation of bridge cranes is the distortion of the running wheels. They cause increased wear of the flange of wheels and rails heads, disrupt the smooth movement of the crane, increase the power consumption, create emergency situations.

The operation of hopper devices, which are used in industry, civil engineering, agriculture and transport, is analyzed on the article. The external factors, which influence the process of charging, storing and discharging of loose cargo (freights) from hopper tanks, are overviewed. The subject of research of presented paper is the improvement of mechanisms of fracturing of products hangs-up (bridges) in hoppers at the stage of designing and setting up of hopper devices.
