Excavators as operating machines or equipment are exposed to diversetypes of
undesired conditions, such as variable workloads, exposure to various environment conditions,
unprofessional or imperfect maintenance and others. This paper demonstrates a case of
anexcavator slewing ring failure which is investigated. The study suggests the failure to be
caused by improper control and inadequate maintenance. The example is illustrated by
photodocumentation with description of damage and probable causes in details. In conclusion,
distinctive types of conditions are listed for consideration while selecting the appropriate
bearing for certain type of load. Further, we outline the necessary conditions needed for
maintenance and monitoring the slew ring during normal operations. |
