摘要： A shovel includes a traveling undercarriage, an upper turning structure, an attachment, an end attachment position detecting device, an object detecting device, and a processor. The upper turning structure is turnably mounted on the traveling undercarriage. The attachment is attached to the upper turning structure, and includes an end attachment at an end thereof. The end attachment position detecting device is configured to detect the position of the end attachment. The object detecting device is configured to detect the position of an object. The processor is configured to control the movement of at least one of the attachment and the upper turning structure, based on the relative positional relationship between the excavation completion position of the end attachment and the position of the object.

摘要： A shovel that performs excavation in accordance with an arm excavation operation including an arm closing operation includes an excavation operation detection part, a position detection part, a maximum allowable pressure calculation part, and an arm cylinder pressure control part. The excavation operation detection part detects that the arm excavation operation has been performed. The position detection part detects the position of the shovel. The maximum allowable pressure calculation part calculates the pressure of the expansion-side oil chamber of an arm cylinder corresponding to an excavation reaction force at a time when the shovel is dragged by the excavation reaction force as a maximum allowable pressure, based on the position of the shovel. The arm cylinder pressure control part controls the pressure of the expansion-side oil chamber not to exceed the maximum allowable pressure when the arm excavation operation is performed.

摘要： A shovel that performs excavation in accordance with a complex excavation operation including an arm or bucket closing operation and a boom raising operation includes an excavation operation detection part, a position detection part, a maximum allowable pressure calculation part, and a boom cylinder pressure control part. The excavation operation detection part detects that the complex excavation operation has been performed. The position detection part detects the position of the shovel. The maximum allowable pressure calculation part calculates the pressure of the contraction-side oil chamber of a boom cylinder corresponding to an excavation reaction force at a time when the shovel is lifted by the excavation reaction force as a maximum allowable pressure, based on the position of the shovel. The boom cylinder pressure control part controls the pressure of the contraction-side oil chamber not to exceed the maximum allowable pressure when the complex excavation operation is performed.

摘要： A shovel management apparatus includes a temporary storing part and an abnormality information storing part. The temporary storing part temporarily stores detection information containing an operation input amount detected by an input amount detecting part of a shovel and physical amounts detected by a plurality of sensors in the shovel. The abnormality information storing part stores abnormality information. A controller performs an abnormality determination based on the detection information. The controller transfers, when an occurrence of an abnormality is determined at a first time, the detection information as the abnormality information, which is stored in a time period from a second time earlier than the first time to at least the first time, from the temporary storing part to the abnormality information storing part.
