A rope shovel has a boom and a hoist rope. The boom has a first end and a second end. The hoist rope extends over the second end of the boom. A digging assembly for the rope shovel includes a shaft, an elongated member supported for movement relative to the boom, an attachment, and a drive link. The shaft is positioned between the first end and the second end of the boom and transverse to the boom, and the shaft includes at least one pinion gear. The elongated member includes a first end and a second end. The attachment is coupled to the first end of the elongated member and is configured to be coupled to the hoist rope. The drive link includes a rack engaging the pinion gear of the transverse shaft such that rotation of the pinion gear moves the drive link and actuates the attachment.

A bucket raising/lowering and opening/closing device (11) of a deep foundation excavator (1) includes a raising/lowering cylinder (12), a first raising/lowering sheave (14) and a first opening/closing sheave (15) that move in an expansion/contraction direction of the raising/lowering cylinder (12), a second raising/lowering sheave (17), a second opening/closing sheave (20), an opening/closing cylinder (18) that moves the second opening/closing sheave (20) to be closer to and to be separated from the first opening/closing sheave (15), a raising/lowering rope (24) that is wound around the first raising/lowering sheave (14) and the second raising/lowering sheave (17), and an opening/closing rope (25) that is wound around the first opening/closing sheave (15) and the second opening/closing sheave (20). In addition, provided are a slack adjustment cylinder (26) that expands and contracts to adjust the slack of the opening/closing rope (25), and a slack adjustment sheave (28) that moves in a direction of being closer to and being separated from the second opening/closing sheave (20) in response to an expansion/contraction movement of the slack adjustment cylinder (26).

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.

A combination of a first unit and a second unit are to be rotatably interconnected through a pin. The first unit includes a first unit body provided with a first pin hole, a first contact member, and a fastening member. The first contact member has a first contact surface. The second unit includes a second unit body provided with a second pin hole, and a second contact surface. The second contact surface is contactable with the first contact surface. The fastening member fastens the first contact member to the first unit body so as to allow the relative position of the first contact member to the first unit body to be adjusted.

Hydro excavation vacuum apparatus that process spoil material onboard the apparatus by separating water from the cut earthen material are disclosed.
