A shovel includes a lower traveling structure, an upper swing structure swingably mounted on the lower traveling structure, and a hardware processor provided on the upper swing structure. The hardware processor is configured to recognize the position of a dump truck and create a target trajectory for a dumping operation.

Shovel

A shovel includes a lower-part traveling body; an upper-part swing body rotatably provided above the lower-part traveling body; an object detecting device provided in the upper-part swing body; a controller as a control device provided in the upper-part swing body; and at least one driven body configured to be operated by an actuator. The object detecting device is configured to detect another shovel in a detection space set around the shovel. The controller is configured to vary a movable range being a range accessible to the driven body, based on a state of an object detected by the object detecting device.

A shovel includes a lower traveling body, an upper turning body mounted on the lower traveling body, an attachment attached to the upper turning body, and a control device mounted on the upper turning body and configured to assist an excavating motion with the attachment. The control device is configured to derive a target excavation depth based on the hardness of an excavation target.

Shovel, and management apparatus and assist device for shovel

A shovel includes a lower traveling body, an upper turning body turnably mounted on the lower traveling body, a boom attached to the upper turning body, an arm attached to the boom, an end attachment attached to the arm, a sensor configured to output detection information about an orientation of a work part of the end attachment, and a processor configured to control operation of the work part to cause the work part to perform compaction of ground by pressing the work part against the ground, wherein the processor is configured to control an operation of the arm and the end attachment according to a lowering operation of the boom to cause an end portion of the work part to perform the compaction of the ground on the basis of the detection information of the sensor.

An excavator according to an embodiment of the present invention includes a lower traveling body, an upper turning body with an attachment mounted on the lower traveling body, and a controller installed in the upper turning body. The controller is configured to restrict movement of the lower traveling body based on information about terrain around the upper traveling body.

Excavator

A shovel includes a lower traveling body, an upper turning body turnably mounted on the lower traveling body, and a controller configured to control a projection device that projects light onto a ground surface. The controller is attached to the upper turning body, and is configured to control the projection device so as to enable visualization of the relationship between the current shape of the ground surface and the shape of a target surface.

Shovel and work support system for construction machine

A shovel includes an attachment attached to a revolving upper body; and a control device including a memory and a processor configured to execute estimating a center of gravity of loaded matter loaded in the attachment, and calculating a weight of the loaded matter based on the estimated center of gravity of the loaded matter.

A shovel includes a lower traveling body, an upper turning body mounted on the lower traveling body, an excavation attachment attached to the upper turning body, a posture detecting device configured to detect the posture of the excavation attachment, an instability detecting device configured to detect information on the instability of the upper turning body due to an excavation load, and a processor configured to correct the posture of the excavation attachment. The processor is configured to open an arm or a bucket of the excavation attachment in response to determining, based on the outputs of the posture detecting device and the instability detecting device, that the excavation load during deep excavation is more than or equal to a predetermined value.

An excavator includes a lower traveling body; an upper turning body mounted on the lower traveling body; an attachment attached to the upper turning body; an attitude detecting device configured to detect an attitude of the attachment including a bucket; and a control device configured to control a toe angle of a toe of the bucket with respect to an excavation ground, based on a transition of the attitude of the attachment, information relating to a present shape of the excavation ground, and an operation content of an operation device relating to the attachment.

Excavator that controls toe angle of bucket

A shovel includes a traveling lower body; a revolving upper body mounted on the traveling lower body; an attachment attached to the revolving upper body; and a control device mounted on the revolving upper body and configured to drive the attachment. The control device controls an angle of a teeth end of a bucket with respect to a target excavation ground, in accordance with hardness of the target excavation ground.

A shovel control method includes performing a plane position control or a height control of an end attachment by an operation of one lever. The plane position control is performed while maintaining a height of the end attachment. The height control is performed while maintaining a plane position of the end attachment.

Shovel control method and shovel control device

A shovel may include a lower travelling body, an upper swinging body mounted on the lower travelling body, an excavation attachment attached to the upper swinging body, an orientation detecting device configured to detect an orientation of the excavation attachment, and a controller. The controller may have a ground surface shape information obtaining part that obtains information relating to a current shape of an excavation target ground surface based on a transition of the orientation of the excavation attachment detected by the orientation detecting device, and an excavation controlling part that controls the excavation attachment based on the information relating to the current shape of the excavation target ground surface obtained by the ground surface shape information obtaining part.

Shovel and control method thereof

A hybrid construction machine includes: a motor generator system connected to an internal combustion engine and performing a motor generator operation; an electric power accumulation system connected to the motor generator system; a load drive system connected to the electric power accumulation system and being driven electrically; an abnormality detection part equipped to the motor generator system, the electric power accumulation system and the load drive system; and a main control part determining whether an abnormality has occurred based on a detection value of the abnormality detection part. When the abnormality determination part determines that an abnormality has occurred, the main control part stops a drive of a drive system in which the abnormality is detected in the load drive system.
