A work machine includes: a vehicle body; a first imaging device that is disposed in the vehicle body and images a first imaging range; a second imaging device that is disposed in the vehicle body and images a second imaging range; and a communication device that transmits a first image in the first imaging range and a second image in the second imaging range to a remote place. At least a part of the second imaging range is set below the first imaging range.

A ground engaging tool locking system includes a pin having a first, proximal head region and a second, distal end region spaced from the first, proximal head region along an axis. The pin includes a groove located between the first, proximal head region and the second, distal end region. A biasing element is disposed at least partially within the groove.

A cartridge includes a body, an aperture extending through the body sized to receive a pivot pin, and a spherical bushing disposed within the body. The cartridge also includes a first internal seal disposed axially on one side of the bushing and a second internal seal disposed axially on an opposite side of the bushing. The cartridge also includes an end cap disposed at least partially within the aperture that abuts the bushing and prevents the bushing from moving axially in a first direction within the aperture.

An attachment is attached to an upper turning body. During a normal operation, a drive means drives the attachment according to an input of an operator to a manipulation device. A sensor detects a motion of an excavator. Based on an output of the sensor, the slip suppression unit detects slip of a traveling body in an extension direction of the attachment and corrects an operation of the attachment performed by the drive means.

A work machine control device for controlling a work machine includes a transport vehicle information acquisition unit and a dumping position specifying unit, the work machine including a swing body and work equipment attached to the swing body and including a bucket. The transport vehicle information acquisition unit acquires position information and azimuth direction information of an unmanned transport vehicle, the position information and the azimuth direction information being detected by the unmanned transport vehicle. The dumping position specifying unit specifies a dumping position for loading earth and sand onto the unmanned transport vehicle based on the position information and the azimuth direction information.

A work system includes an operation device that transmits an operation signal, a work machine that operates on the basis of the operation signal, and a transport vehicle that outputs a traveling control signal in a case where a fault in communication between the operation device and the work machine occurs.

A dipper handle includes a dipper tube, a dipper engagement member, and an intermediate member between the dipper tube and the dipper engagement member. The dipper tube has a substantially cylindrical outer surface and a contoured inner surface. The contoured inner surface results in multiple wall thicknesses for the dipper tube, including a first thickness proximate a first end and a second, larger thickness, proximate a second end. The second end is configured for coupling to the intermediate member.

A track slider mounting plate kit includes a first shark fin configured mounting plate including a first bottom mounting surface, a first beveled surface extending from the first bottom mounting surface, and a second beveled surface that extends from the first beveled surface, forming a first oblique angle with the second beveled surface. A track slider is attached to the first shark fin configured mounting plate that has a top surface extending from the rear surface toward the front surface defining a top surface radius of curvature ranging from 2200 mm to 2600 mm.

A work machine is capable of rotating an attachment while appropriately supporting a load applied to the attachment. The work machine has a hydraulic cylinder attached to a body side surface of an arm and a first link rod extending along a back side surface of the arm. A second link rod is rotatably supported via a first pin extending in the width direction of a front working device, and has one end projecting toward the back side surface of the arm and the other end projecting toward the body side surface thereof. One end of the first link rod is rotatably connected to the attachment. One end of the second link rod is rotatably connected to the other end of the first link rod, and the other end thereof is rotatably connected to a distal end of a cylinder rod of the hydraulic cylinder via a third pin.

A control device outputs an operation signal of a work equipment and a swing body for moving a work equipment to a loading point when receiving a loading command signal. The control device does not output a dumping operation signal for causing the bucket to dump earth in a case where an azimuth direction in which the swing body faces is within a first region from a starting point azimuth direction to a predetermined reference azimuth direction, the starting point azimuth direction being an azimuth direction in which the swing body faces when the loading command signal is received. The control device outputs the dumping operation signal in a case where the azimuth direction is within a second region from the reference azimuth direction to an end point azimuth direction in which the swing body faces when the work equipment is positioned at the loading point.
