Abstract :
In the North Bohemia there the considerable problem with strip mine occurred. The drive of the coal-conveyor started to overload one of three motors. This problem was obstructing the operation because two motors was driven simultaneously one gear box, while the third motor operated its own gearbox. This paper summarizes the initial conditions, the problem analysis, diagnostic measurement and final solution.
