Technologies for lining the inner walls of excavator buckets with sheets of ultrahigh molecular polyethylene (UHMWPE RE-1000) are being introduced at the Pereyaslovsky section (an asset of the Russian Coal company in the Krasnoyarsk Territory).
Lining allows you to increase the service life of the bucket, reduce the impact of shock loads, reduce the sticking of overburden and the impact of friction on the surface of the working equipment of excavators of the EKG type (crawler excavator). Carrying out these works contributes to increasing the resource and productivity of mining equipment, as well as reducing operating costs, explained in the department of the chief mechanic of the enterprise.
Currently, specialists of the repair and mechanical section group, taking into account the recommendations of suppliers of lining material, have mastered and successfully applied the technology of lining excavator buckets with sheets of ultra-high molecular weight polyethylene, one bucket of the EKG-10 excavator and two buckets of the EKG-8I excavator have been lined. At the same time, one bucket, upgraded with this technology, has been successfully in operation for more than 1 year.
“The quality of the work performed by the specialists of our enterprise is not inferior to the quality of the work performed earlier by the contractors. It should be noted that in case of defects and separation of individual lining elements, we have the opportunity at any time to promptly replace the failed lining material sheets, having a reserve in the material warehouse of the branch, and therefore the time of emergency downtime of the excavator is reduced,” explained Konstantin Zhbanov, Deputy Chief mechanic of the Pereyaslavsky section.
