Dec 02, 2018 · The low-frequency vibration of the bucket wheel excavator has an important impact on the fatigue life of the structures. For conventional vibration testing methods, it is difficult and expensive to excite the overall low-frequency vibration of the whole machine. Hence, in this paper, the excitation method that uses the belt-supporting rollers on the boom as an exciter is tried to excite the

Bucket wheel excavators are the ideal solution: they can move as much lignite and overburden in a day as 40,000 workers-240,000 cubic meters, equivalent to more than 10,000 dump truck loads. The material is picked up by the bucket wheel and transported on conveyors over three meters in width. The overburden is dumped by spreaders. 2.
