摘要: The invention provides a liner sleeve (8) adapted, in use, to be interposed between the external periphery of a round shank (3) of a point attack, mineral cutter pick (1), and the internal periphery of a circular, shank-receiving bore (5) of a pick box (6), the sleeve (8) being constituted by a plurality of individual rings (14A, 14B, 14C) stacked end-to-end in abutting relationship about a common longitudinal axis (15), the rings (14A, 14B, 14C) together having an axial length (17) approximating to the axial length (12) of the bore (5). The invention also includes a pick box (6) provided with such a sleeve (8), and also a combination of pick (1) and pick box (6)

摘要: A tip (1A, 1B, 1C, or 1D) of hard material has in at least one external surface, a wear line or marker (12) in the form of a rib (13, 16 or 17), or a groove (15) capable of being felt by a thumb or finger of a miner, so that a visual inspection for wear is unnecessary. The invention also includes a pick (5) provided with such a tip.
