A boom mounting assembly for attachment to an agricultural machine is disclosed, which may comprise a primary frame, and a boom support frame configured to support a boom and being suspended from the primary frame to pivot in a transverse plane around a longitudinal axis of rotation provided in a pivot point. The boom support frame may comprise a first sub-frame connected to the primary frame; a second sub-frame supported by the first sub-frame in support sections provided on opposite sides of the pivot point in a transverse direction; and an actuator connected to the sub-frames and operable such that the support sections move relative to the pivot point to increase and decrease, in the transverse direction, a respective distance on opposite sides of the pivot point at the same time. Further, a method for controlling operation of a boom mounting assembly attached to an agricultural machine is provided.

A shovel includes a lower traveling body, an upper swiveling body mounted to the lower traveling body, attachments including a boom attached to the upper swiveling body, an arm attached to an end of the boom, and a bucket that is an end attachment attached to an end of the arm, and a control device configured to control swiveling of the upper swiveling body and movement of the attachments so that an end portion of the bucket moves along an extension of a slope toe, which is a target line.

Systems and methods for compensating dipper swing control. One method includes, with at least one processor, determining a direction of compensation opposite a current swing direction of the dipper and applying the maximum available swing torque in the direction of compensation when an acceleration of the dipper is greater than a predetermined acceleration value. The method can also include determining a current state of the shovel and performing the above steps when the current state of the shovel is a swing-to-truck state or a return-to-tuck state. When the current state of the shovel is a dig-state, the method can include limiting the maximum available swing torque and allowing, with the at least one processor, swing torque to ramp up to the maximum available swing torque over a predetermined period of time when dipper is retracted to a predetermined crowd position.

A measurement device of a shovel, wherein the measurement device is installed in the shovel including a lower travelling body that performs traveling operation; an upper turning body pivotably mounted on the lower traveling body; a boom that is attached to the upper turning body, the boom being included in an attachment; and an arm that is attached to the boom, the arm being included in the attachment, wherein the measurement device measures a landform in a vicinity of the shovel at a plurality of positions based on an output of a device that captures information on a distance to a surrounding measurement target, the device being located above the lower traveling body.

an An arm for a material handling machine includes a first plate, a second plate, and a pair of side walls. The second plate includes two opposite edges and a first of the pair of side walls is welded inward of the first edge of the second plate. A second of the pair of side walls is welded inward of the opposite edge of the second pate to form two flanges, with each of the two flanges extending on opposite sides of the second plate and having at least one hole at each of its ends. Each of the flanges has a length that is longitudinal with respect to the arm and a width that is transverse with respect to the arm and the length of each flange is between and of the length of the arm.

A dipper door trip assembly includes a dipper, a dipper door pivotally coupled to the dipper, a linkage assembly including a sliding latch bar disposed at least partially in the dipper door, and a latch keeper coupled to the dipper. The latch keeper includes a roller that engages and disengages the latch bar.

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.

A stabilizer system includes a first object that moves relative to a second object and includes a first actuator coupled to a first wear pad. The first actuator drives the first wear pad to contact a first side of the second object to control motion of the first object relative to the second object. The first actuator operates in a first mode and in a second mode. While operating in the first mode, the first actuator applies a first force to the first wear pad to block the motion of first object relative to the second object. While the first actuator is operating in the second mode, the first actuator applies a second force, lower than the first force, to the first wear pad to enable the motion of the first object relative to the second object.
