An eccentric assembly for a walking mechanism is provided. The eccentric assembly includes a barrel member and a shaft member. The barrel member includes a circumferential portion extending in a longitudinal direction and a web portion extending inwardly from the circumferential portion. Further, the web portion includes a cut-out region and an inner periphery outlining the cut-out region. The shaft member includes a tubular portion extending in the longitudinal direction and a flange portion extending outwardly from the tubular portion. The flange portion includes an outer periphery. Further, the shaft member is coupled to the barrel member such that the outer periphery of the flange portion substantially conforms to the inner periphery of the web portion. Further, the flange portion is configured to adjust an eccentricity of the shaft member with respect to the barrel member.

A dragline bucket includes a base member defining a first end, a second end, and a third end. The dragline bucket also includes a first side wall, a second side wall, and an end wall extending from the base member proximate to the third end of the base member such that the end wall is connected to each of the first side wall and the second side wall. The end wall includes a first portion connected to the base member such that a first angle is defined between the base member and the first portion. The end wall also includes a second portion extending from the first portion. The second portion is substantially perpendicular to the base member. The end wall further includes a third portion extending from the second portion such that a second angle is defined between the second portion and the first portion.

A walking assembly for a machine includes a walking shoe and a driving assembly including a walking frame, a driving member, and a linkage member pivotally coupled to the driving member and the walking shoe. The walking assembly also includes a sliding assembly coupled to the walking shoe and the walking frame. The sliding assembly includes a support structure adapted to be received within the walking shoe and sliding assembly plate member mounted on the support structure. The sliding assembly further includes a pair of roller chains adapted to roll on a contact surface of the plate member. The sliding assembly includes a sliding shoe adapted to be coupled with the walking frame that is in rolling contact with the pair of roller chains. The sliding assembly also includes a guiding assembly to retain the sliding shoe in rolling contact with the pair of roller chains.

A novel cable construction provided an armored covering over a cable containing high-strength synthetic filaments. The synthetic cable is provided with a strong and tough termination where it attaches to heavy machinery, such as mining machinery. An external armoring is then provided for a desired portion of the cable (up to the entire length of the cable). A collar is preferably provided to seal the end of the armoring portion to a cable jacket (where a cable jacket is present).

A method and hardware for damping and controlling unwanted motion in the fixed rigging of large machines. In a first approach large clamp blocks are added to multi-cable rigging systems. These blocks use a first cable to damp the motion of an adjacent cable. The invention also encompasses adding armored sections to synthetic cables to enhance their abrasion resistance and cut resistance.
