A power-operated tool shifts an actuating member bidirectionally to mount and remove chisels from holders.
A hydraulic piston displaces mineral cutter picks axially within their bores using controlled fluid pressure.
Optical imaging captures milling tool positions to compare against reference values, eliminating subjective visual inspection and production interruptions.
A wireless camera network integrates into longwall face supports using intrinsically safe electronics and local antennas.
A rotatable cutting tool holder base assembly uses an alignment pin to secure the tool holder within a bore for precise orientation.
Segmented tooth formation uses complementary projections to rigidly hold a mineral breaking pick head, reducing wear while enabling easy replacement.
A movable maintenance flap on the machine frame underside provides storage compartments and a pivot seat for replacement tools.
Segmented carbide or sintered diamond inserts deflect abrasive materials to reduce replacement downtime and extend cutter bit service life.
Segmenting the cutter bit allows quick replacement of the worn element without removing the drum, reducing maintenance downtime.
