Excavator is the main equipment in mining production, the working device of bucket tooth and bucket in theadapter assembly is firm and not directly related to the safety and efficiency in the process of using.
According to the requirements of design and application: bucket teeth and adapter assembly, the outline of the contact surface and the inner cavity of adapter bucket tooth should reach more than 75%. But in the early stage ofelectric excavator bucket teeth and put into use, adapter is the original new piece, after several times of replacementparts made of adapter have slight wear, at this time will not be noticed. To continue after a period of time after useadapter wear intensifies, geometric size, even installed a new tooth will loose.Especially when the non originalexcavator bucket teeth parts factory production, due to various reasons, can not fully guarantee the inner bucket tooth size consistent with the original design manufacturing plant, the assembly will be more loose. Continue to work in the above two kind of loose situation, serious when the bucket teeth can break or fall off, extremely easy to cause theserious accident crusher tape cut etc..
