Highest efficiency

Tyrolit products convince all along the line

Cutting and grinding wheels from Tyrolit are proving a lasting success for users carrying out maintenance work at Gran in southern Germany. As a traditional, family-run company in Bavaria, Gran specializes in gravel extraction with dragline buckets mounted on duty cycle crawler cranes.

The very hard materials from which dragline buckets are made pose a particular challenge when it comes to maintenance work. The highly wear-resistant Hardox or manganese steel used requires powerful grinding tools for processing. The aim is to remove wear, rust and surface damage from the dragline buckets in order to restore their performance as quickly as possible and thus reduce idle times of the duty cycle crawler crane to a minimum.

Applications

Cutting and grinding the hardest materials

By using Tyrolit cut-off and grinding wheels, maintenance work can be carried out efficiently and at the highest quality. CERABOND X wheels in particular impress with their durability, high removal rate and cutting ability, which means fewer tool changes are required and machine downtimes are minimized. The dragline bucket is successfully maintained, which extends its service life and significantly increases operational efficiency.

Cutting: The team uses high-performance PREMIUM or CERABOND X cut-off wheels for high-precision cutting of worn or damaged metal parts on the dragline bucket. These enable clean cuts and protect the intact areas of the workpiece.
Grinding: The CERABOND X high-performance rough grinding wheels offer outstanding removal rates and the longest lifetimes for a wide range of applications, which is particularly advantageous for large-area machining. Thanks to their high efficiency, work can be completed extremely quickly and thoroughly.
