A self-cleaning elevator flight bracket system is described for attachment to an elevator or conveyor flight for pipeline padding and backfill operations. The system is designed for bolt-on installation to padding equipment elevator flights, or cleated conveyor feeders. Built-up soil, clay, and other debris, which interfere with elevator drive mechanisms, are self-cleaned with the system. The assembly is universal to fit a variety of existing bolt patterns on elevator flight plates or feeder conveyor cleats. Flexible cables are directed to engage and remove excessive backfill material build-up. While operating padding machinery in heavy soil, or clay, material builds up in the space between the elevator flights and the elevator side wall. This leads to impeding the drive mechanism. With the use of the presently described elevator flight bracket and flexible cable or fingers, the upward movement of the elevator acts to self-clean the machinery and allows for longer operation.

An assembly and method for using a flexible tensile member as part of the rigging for a heavy machine such as those used in the mining industry. The inventive tensile member includes a core surrounded by a separate armor layer. The armor layer assumes various forms, including a hollow cylinder having a substantial wall thickness. The core produces excellent strength in tension (and with a substantial reduction in weight). The armor layer protects the core from external blows and forces produced by the weight of the other parts of the machine's rigging and the hostile environment in which the machine operates.

A dump block assembly for a dragline bucket rigging assembly including a frame assembly having a first side frame and a second side frame attached to and parallel to the first side frame. The first side frame includes a first attachment portion having a first upper connection portion, a first lower connection portion opposite the first upper connection portion, and a first central connection portion spaced apart from and in between the first upper connection portion and the first lower connection portion. The second side frame includes a second attachment portion having a second upper connection portion, a second lower connection portion opposite the second upper connection portion, and a second central connection portion spaced apart from and in between the second upper connection portion and the second lower connection portion.

A method for determining stability of a vehicle having a load suspended from the vehicle is provided. The method can include obtaining measurements from a plurality of sensors positioned on the vehicle, obtaining a measurement from a vehicle accelerometer operative to determine an inclination of the vehicle, determining a position of the load suspended from the vehicle, determining a slung load of the load suspended from the vehicle, using the determined slung load and the determined position of the load suspended from the vehicle, determining tipping moments acting on the vehicle, determining righting moments acting on the vehicle and determining a tipping stability based on the determined tipping moments and determined righting moments.

A hoist drum is disclosed for use with a power shovel. The hoist drum may have a body that is hollow and generally cylindrical, and an anchor connected to an outer annular surface of the body. The hoist drum may also have at least one stiffener located inside the body and extending in an axial direction of the body across the anchor.

A protection system for protecting wire ropes may include a gusset plate(s), a bracket(s), and/or a protection device(s). The gusset plate(s) and bracket(s) act like stops for the protection device(s). Each protection device includes a pair of pieces that when assembled form a tube to go about a cable wire for a cable shovel.
