  • Patent number: 10422222
    Abstract: 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.

  • Patent number: 10366177
    Abstract: A method of designing a cutting drum for earth moving equipment is disclosed. The cutting drum has two or more ring segments, each ring segment comprising a plurality of cutting tools, and the rotational position of at least one ring segment is adjustable relative to one or more other ring segment and fixable in the new rotational position. The method involves inputting a plurality of design parameters of a cutting drum into a computer program, performing a computer simulated analysis of the cutting drum using the computer program to determine at least one operational value associated with at least one design objective, using the computer simulated analysis to determine the relative locations of the ring segments that correspond to the at least one design objective, and rotating the or each adjustable ring segment relative to at least one other ring segment so that the relative locations of the ring segments correspond to the at least one design objective.

  • Patent number: 10094078
    Abstract: In a cold planer, a rotor housing partially enclosing a rotor may have a rotor housing side wall with retention plates defining a space in which a rotor housing side plate disposed so that the side plate can translate and rotate relative to the rotor housing. A pair of side plate lift cylinders may operate to vary a vertical position of the rotor housing side plate and a rotation of the rotor housing side plate about a horizontal axis relative to the rotor housing. The cold planer may use information from one or more distance sensors to identify contours in a work surface over which the cold planer is propelled, and actuate the lift cylinders to adjust the position and orientation of the rotor housing side plate to closely track the contour of the work surface and substantially prevent ground material from escaping from the rotor housing.

  • Patent number: 8789891
    Abstract: Methods and apparatuses for producing a planar cavern are provided. The planar cavern is formed by first creating a continuous bore that extends through a subsurface resource deposit. The drill head used to create the bore can be steered in response to information about the concentration of the resource in the strata through which the drill head is passing, in order to keep the bore within resource deposit. The continuous bore can be formed by connecting first and second bores at a point within the subsurface resource deposit. After the continuous bore has been formed, a sawing assembly is placed within the continuous bore. The sawing assembly is then moved, in a continuous or in a reciprocating fashion, within the continuous bore. As the sawing assembly is moved, it is maintained under tension, to create a planar cavern. By thus exposing a large area of the resource deposit, a relatively large amount of the resource deposit can be dissolved in a solvent introduced to the planar cavern per unit time.

  • Publication number: 20140077578
    Abstract: A cutter head includes a first member, a cutting bit, and a second member. The first member includes a first end and a second end and includes a first mass. The cutting bit is coupled to the first member proximate the second end. The cutting bit includes a cutting edge rotatable about the axis. The second member is rotatable about the axis and includes a second mass eccentrically positioned with respect to the axis. Rotation of the second mass causes the first member and the cutting bit to oscillate.

  • Patent number: 8424973
    Abstract: A method of mining a valuable metal or material in an ore body is described. The method comprises the steps of: a) placing a cushion in a stope whereby the cushion creates a void into which fragmented rock can expand during subsequent blasting operations for a second or subsequent panel; and, b) maintaining the void until blasting operations occur whereupon the void is caused to collapse to accommodate fragmented ore generated during blasting operations.
