The disclosure relates to a work machine, in particular a duty-cycle crawler crane, having an undercarriage which comprises a middle part and at least one crawler carrier connected to the middle part and having at least one electric traction drive, wherein at least one energy transmission line for supplying power to the traction drive and at least one further supply line runs between the traction drive and the middle part. According to the disclosure, the at least one energy supply line and the at least one further supply line run together in a separate protection means outside the middle part and the crawler carrier.

A hitch assembly for a bucket of a work machine includes a bracket adapted to be removably coupled with the bucket at any one of a plurality of hitch locations. The bracket defines a first bracket end and a second bracket end. The bracket is adapted to be coupled with a drag chain proximal to the first bracket end. The hitch assembly also includes one or more first mechanical fasteners adapted to removably couple the bracket with the bucket. The hitch assembly further includes a second mechanical fastener adapted to be coupled with each of the bucket and the bracket proximal to the second bracket end. Based on a removal of the one or more first mechanical fasteners from the bucket and the bracket, the bracket and the second mechanical fastener rotate relative to the bucket for disposing the bracket at any one of the plurality of hitch locations.

A pinned connection assembly includes a first rigging component, a second rigging component, a rigging pin, a locking pin, and a lock. The first rigging component has an end with at least one coupling aperture and at least one retention aperture that is transverse to the coupling aperture. The second rigging component has an end with at least one coupling aperture. The rigging pin has an end with a retention groove. The rigging pin is inserted through the coupling apertures of the first and second rigging components. The locking pin has an end with a locking groove. The locking pin is inserted through the retention aperture and the retention groove. The locking groove has guide, transitional, and locking portions for engaging a key of the lock.

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.

Shaker assemblies for dewatering slurries are disclosed. The shaker assemblies may include a positioning device which limits movement of the vibratory frame of the shaker assembly relative to a subframe when the vibratory frame is moved from a raised operating position to a lowered position. The positioning device may guide the vibratory frame as it is lowered from the raised position to the lowered position. In some embodiments, the shaker assembly includes a locking device for locking the vibratory frame to the subframe when the vibratory frame is in the lowered position.

An equalizer assembly for a mining machine includes a single piece cast equalizer having a first end and a second, opposite end. The assembly also includes a first end cap configured to be coupled to a dipper of the mining machine, the first end cap including a first bushing configured to receive the first end of the equalizer. The assembly also includes a second end cap configured to be coupled to the dipper of the mining machine, the second end cap including a second bushing configured to receive the second end of the equalizer.
