The present invention provides a reversible bucket coupler device and method of use for reversing the orientation of a bucket used with an excavator so that the teeth of the bucket is facing away from the cab of the excavator and method of use. The reversed orientation of the bucket using the reversible bucket coupler device provides an operator of an excavator the ability to complete tasks in a more efficient, clean and safe manner, as well as providing much needed flexibility in the way excavation projects can be performed.

A mining machine assembly includes a dipper having a main body, the main body having a front side, a back side, a bottom side, and a top side. A ground engagement portion extends from the front side, the ground engagement portion including digging teeth. The mining machine assembly also includes a hoist rope attachment assembly coupled to the dipper. The hoist rope attachment assembly is configured to directly couple a hoist rope to the dipper. The hoist rope attachment assembly includes a cam having a first portion extending from the top side of the main body of the dipper, and a second portion that extends from the first portion and away from the main body and digging teeth.

An excavator having a rotatable arm is disclosed. The excavator includes: a vehicle body configured to have a hydraulic pump; a boom connected to the vehicle body at one end thereof; a boom cylinder coupled between the vehicle body and the boom, and configured to receive hydraulic energy from the hydraulic pump and operate the boom; an arm connected to the other end of the boom; an arm cylinder coupled between the boom and the arm, and configured to receive hydraulic energy from the hydraulic pump and operate the arm; a bucket connected to an end of the arm; and a bucket cylinder coupled between the arm and the bucket, and configured to receive hydraulic energy from the hydraulic pump and operate the bucket. The arm includes: a first body, a second body, and a rotation module configured to enable the rotational movement of the second body.

A hybrid bucket assembly for a work vehicle having movable loader arms includes a structural skeleton having a frame, one or more support struts mounted to the frame, and one or more brackets coupled to the support struts configured to interface with a carrier at distal ends of the loader arms. A bucket shell is mounted to the skeleton that defines a carry volume for materials. Force loading on the bucket shell is carried by the skeleton through the struts.

A mining machine includes a boom, a handle coupled to the boom, a dipper coupled to the handle, and a dipper door pivotally coupled to the dipper. The mining shovel also includes a dipper door trip assembly including a trip motor coupled to the boom, a trip drum coupled to the handle, a linkage assembly coupled to the dipper door, a first actuation element extending directly from the trip motor to the trip drum, and a second actuation element extending directly from the trip drum to the linkage assembly.

A digging machine (1) such as a face shovel is controlled in an automated dumping sequence in which the bucket (10, 10′) is pivoted to a first angular orientation before opening and, optionally, re-orienting to a second, slightly more forwardly inclined angular orientation. The first orientation may relieve the front part (20) of the bucket from the load while the second orientation is selected to discharge the load at an optimal trajectory. The bucket may move to a third angular orientation before closing the front part (20) against gravity.

A posture acquisition unit acquires posture information of a bucket. A topography acquisition unit acquires topographical information indicating a three-dimensional shape of a construction target of a work machine. A projected image generation unit generates, based on the posture information and the topographical information, a projected image including a ground projection figure obtained by projecting teeth of the bucket on a ground surface of the construction target. A display control unit outputs a display signal for displaying the projected image.

A variable track joystick device includes a support housing, a joystick movable with respect to the support housing, and a joystick guidance mechanism controllable to selectively confine joystick movement to a predetermined track pattern. During operation of the variable joystick device, a controller determines when the variable track joystick device is placed in a selected one of (i) a first mode in which joystick movement controls the first work vehicle function and (ii) a second mode in which joystick movement controls the second work vehicle function. The controller further commands the joystick guidance mechanism to restrict joystick movement to the predetermined track pattern when the joystick device is placed in the first mode, while permitting joystick movement outside of the predetermined track pattern when the joystick device is placed in the second mode.

A work vehicle includes work equipment having a work tool and a support member supporting the work tool. A display control system controls a display device provided outside the work vehicle. The display control system includes a captured image acquisition unit, a supplementary image acquisition unit, a display image generation unit, and a display control unit. The captured image acquisition unit acquires a captured image captured by an imaging device mounted on the work vehicle. The supplementary image acquisition unit acquires a supplementary image representing information related to the work vehicle. The display image generation unit generates a display image in which the supplementary image is disposed in an area where a side surface of the support member can be shown in the captured image. The display control unit outputs a display signal in order to display the display image on the display device.

The present invention relates to a method of determining an angle of a piece of working equipment of a machine, wherein the machine has an undercarriage and a superstructure rotatable with respect thereto, wherein the piece of working equipment is fastened to the superstructure via a swivel joint such that the angle of rotation of the swivel joint is orthogonal to the axis of rotation of the rotatable superstructure, wherein the piece of working equipment is provided with an IMU, that is in an inertial measurement unit, that is configured to detect an angular speed in three spatial directions that are preferably perpendicular to one another, and wherein a first of the three spatial directions, whose angular speed ({dot over (θ)}.sub.y) is detectable by the IMU is in parallel with the axis of rotation of the swivel joint. The method is characterised in that an angular speed ({dot over (θ)}t.sub.z) that occurs on a rotation of the superstructure is detected by the IMU and an angle of the piece of working equipment relative to the axis of rotation of the superstructure is determined on the basis of the detected angular speed ({dot over (θ)}t.sub.z) of the superstructure.
