A hydraulic actuator drives an expulsion mandrel along an arcuate path to remove worn chisels from milling drum holders.
Varying rib width directs abrasive debris while reducing hard metal expenditure and extending tool life.
Automated imaging systems analyze cutting drum images to detect wear thresholds, eliminating production halts for manual inspections.
A rebound cage guides the drop weight after impact, reducing metal fatigue and environmental noise.
Deposition welding joins a hard metal plate to an abrasive tool body, resolving low wear resistance from conventional low-carbide filler materials.
Segmented tool holder shank combines tapered and cylindrical sections to secure cutting bits, reducing machine downtime from broken components.
Segmented boom and shield components resolve the trade-off between structural simplicity and cutting efficiency by enabling precise hydraulic positioning.
Interlocking protrusion and recess inhibit toolholder rotation, reducing frictional wear and loosening in milling drum applications.
Segmented retainer and spring mechanisms enable rapid bit replacement in mining machines while maintaining rotational stability and operational security.
A road planing tool bit uses circumferential retaining teeth to engage a toothed inner rim on the assembling socket for secure mechanical attachment.
