    摘要: A tool includes an actuator assembly, a rod, a first nut, and a second nut. The actuator assembly includes a cylinder, a ram, and a bore extending through the cylinder and the ram. The cylinder includes an internal chamber supporting the ram, a first end, a second end, and a reaction surface positioned proximate the first end. The ram is movable relative to the cylinder and positioned adjacent the second end of the cylinder. The rod extends through the bore of the actuator assembly. The first nut is selectively coupled to one of a first end of the rod and a second end of the rod, and defines a first dimension larger than the bore width of the bit block. The second nut is selectively coupled to the other of the first end of the rod and the second end of the rod, and defines a second dimension less than the bore width.

    摘要: A crawler track includes a link and is driven in a direction of travel by a sprocket having a plurality of teeth. The link includes a pad, a first grouser, and a second grouser. The pad defines a first surface, a second surface opposite the first surface, a first end, and a second end spaced apart from the first end along the direction of travel. The pad defines at least one opening extending through the pad between the first surface and the second surface, and the opening is operable to receive a sprocket tooth. The first grouser is positioned on the first surface proximate the first end of the pad, while the second grouser is positioned on the first surface proximate the second end of the pad. The first grouser and the second grouser extend in a direction substantially perpendicular to the direction of travel of the track.

    摘要: A cutting bit assembly includes a block, a bit sleeve, and a seal. The block includes a first bore and a fluid passage. The fluid passage includes a first portion and a second portion in fluid communication with the first portion. The first portion is oriented obliquely with respect to the first bore, and the second portion extends at least partially around the perimeter of the first bore. The bit sleeve includes a shank, a flange, and a second bore extending through the shank and the flange. The shank is positioned within the first bore of the block such that a surface of the flange engages a first end surface of the block. The seal is positioned between the second portion of the fluid passage and the shank to prevent contact between a fluid in the fluid passage and the outer surface of the shank.

    摘要: A cutter head for a longwall shearer includes a drum, a vane, and a plurality of cutting bits. The drum includes a first end and a second end and defines an axis of rotation extending therebetween. The vane is connected to the drum and extends in a helical manner along at least a portion of the axis. The vane defines an edge surface extending along an outer perimeter of the vane. The cutting bits are secured to the vane edge surface. Each cutting bit includes a block and a bit coupled to the block. The block is secured to the edge surface and extends beyond the outer perimeter of the vane.
