A bucket for an underground loading machine includes an opened bucket front and a concaved bucket back. To provide abrasive wear resistance, the bucket includes a paddle plate joined to the bucket underside of the bucket floor. The paddle plate can have a trumpet-shape tapering from flared forward edge to a plate tail disposed toward the concaved bucket back. The bucket may be configured as a wedge bottomed bucket and include a plurality of spacer wedges disposed between and spacing apart the bucket underside and the paddle plate.

A skid device and a loader bucket assembly includes the skid device, which include a ski-shaped base plate. The skid device is attachable to a front end of a loader bucket including a plurality of mounting holes for securing an accessory, such as an edge plate and a toothbar, to a bottom side of the loader bucket at a front side thereof, with a portion of the accessory extending forwardly of a front edge of the loader bucket when the accessory is mounted to the loader bucket. The skid device is also attachable to the loader bucket without the accessory mounted thereto. Two or more skid devices can be attached to the front end of the loading bucket to enable it to move materials on the ground.

A work tool includes a bucket and a hydraulic actuator that pivots the bucket on a frame. The loaded bucket applies a maximum compressive force Fc against a resilient bump stop, which reacts a proportion of the applied force as a restoring force Fr against the actuator. A major proportion of the applied maximum compressive force Fc is reacted between the piston and cylinder, while the restoring force Fr is arranged to be greater than the force Fe applied by the self weight of the empty bucket, such that (Fc>2.Math.Fr), and (Fr>Fe).

A work machine includes a chassis, a boom coupled to the chassis, and a work implement coupled to the boom and movable relative to the chassis. In system may further include dynamic payload weighing system configured to measure the payload weight on the work implement. The system may also include an electrohydraulic system controller in communication with the dynamic payload weighing system and an electrohydraulic control valve electrically coupled to the electrohydraulic system controller and moveable to a plurality of weight-specific valve positions based on the measured payload weight on the implement.

A mining machine includes a frame, a boom, an elongated member supported by a pivot element for movement relative to the boom, and a digging attachment. The boom includes a first end coupled to the frame and a second end opposite the first end. The pivot element is positioned between the first end and the second end of the boom. The hoist rope includes a portion extending over the second end of the boom. The member includes a first end, a second end, a first portion proximate the first end of the member, and a second portion positioned between the first portion and the second end of the member. At least a portion of the second portion is oriented at an angle relative to the first portion. The digging attachment is coupled to the second end of the member and is supported by the hoist rope.

Disclosed embodiments include backscreens, backscreen accessories for implements of power machines, and implements including the same. In the backscreens or backscreen accessories, a first backscreen portion is attached to a frame of the implement, for example by welding. The first backscreen portion includes at least one first portion interface feature. A second backscreen portion has at least one second portion interface feature. The at least one first portion interface feature and the at least one second portion interface feature are configured to engage one another to removably couple the second backscreen portion to the first backscreen portion.

Screening bucket (100) provided of a screening basket (1) comprising a first cylindrical body (30) having a central axis (51) and a plurality of first holes (32); an actuating unit (50) being provided to rotate the first cylindrical body (30) around the central axis (51); a second cylindrical body (60) being coupled to the first cylindrical body (30) in a longitudinally free and angularly fixed manner; the second cylindrical body (60) having a plurality of second holes (62) facing the first holes (32); an actuating unit (50) being arranged between the first and the second cylindrical bodies (30) (60) to move them longitudinally relative to each other.

A power operated locking device for securing for example a tooth or an adaptor, to a ground engaging system, the lock having an internal motor, and sensing system operated by remote wireless technology to unlock and lock the locking device, and a wireless transmitting handheld device for the locking, and unlocking of the power operated locking device, wherein the motor and drive and electronic response circuits are all contained within the power operated locking device.

The invention relates to a bucket lip for earth moving machines, said bucket lip comprising a front blade (1) provided with a plurality of projections (2) for placing a plurality of teeth; a plurality of front cavities (3) placed between said projections (2) for placing a plurality of front guards; and a plurality of tension elements (4) for distributing the stress produced while using the bucket; wherein said tension elements (4) are arranged between said projections (2), after said front cavities (3). The invention allows optimizing stress distribution while using the machine, obtaining a more flexible bucket and subjecting said bucket to less fatigue, such that it requires fewer repair tasks.
