    摘要： A tip for use on an earth working roll for mining, construction and public works machines such as crushers, surface miners, milling machines and the like includes a working end provided with side relief to reduce drag and wearing, require less power to drive the rolls, and lengthen the usable life of the tip. The working end can also have a generally flat front surface to improve the yield in a crushing or other similar operation. The tip includes a base and a wear cap releasably secured together by a retainer.

    摘要： A wear assembly for use on various kinds of earth working equipment that includes a base with a supporting portion, a wear member with a cavity into which the supporting portion is received, and a lock to releasably secure the wear member to the base. The supporting portion is formed with top and bottom recesses that receive complementary projections of the wear member. These recesses and projections include aligned holes so as to receive and position the lock centrally within the wear assembly and remote from the wear surface. The hole in the wear member is defined by a wall that includes a retaining structure provided with an upper bearing surface and a lower bearing surface for contacting and retaining the lock against upward and downward movement in the hole.

    摘要： A pick for mineral winning includes an elongate shank configured to be positioned into a cavity of a holder. A profile is defined on an outside surface of the shaft which includes a first surface formed into the profile and disposed to receive a leveraging device to enable a first forced translational movement of the shaft relative to the holder, and a second surface formed into the profile and disposed to receive the leveraging device to enable a second forced translational movement of the shaft relative to the holder.
