Abstract

A shovel includes an attachment attached to an upper turning body and a processor configured to calculate a weight of a load carried in the attachment in accordance with a mode selected from a plurality of modes with respect to timing of detection.

Claims (10)

1. A shovel comprising:

an attachment attached to an upper turning body, the attachment including a boom; and

a hardware processor configured to calculate a weight of a load carried in the attachment in accordance with a method of detecting the weight of the load among a plurality of methods of detecting the weight of the load, the plurality of methods of detecting the weight of the load being different in timing of detecting the weight of the load, the plurality of methods of detecting the weight of the load including a first method in which the weight of the load is calculated during turning of the upper turning body and a second method in which the weight of the load is calculated during raising of the boom.

2. The shovel according to claim 1 , wherein the hardware processor is configured to compensate a torque for rotating the attachment on the basis of an inertial force and a centrifugal force of the attachment in the second method.

3. The shovel according to claim 1 , wherein the hardware processor is configured to switch from operating in one method among the plurality of methods to operating in another method among the plurality of methods, on the basis of an operation state of the shovel.

4. The shovel according to claim 1 , wherein the hardware processor is configured to switch from operating in one method among the plurality of methods to operating in another method among the plurality of methods, in response to an input by an operator.

5. A shovel comprising:

an attachment attached to an upper turning body; and

a hardware processor configured to calculate a weight of a load carried in the attachment in accordance with a method of detecting the weight of the load among a plurality of methods of detecting the weight of the load, the plurality of methods of detecting the weight of the load being different in timing of detecting the weight of the load,

wherein the hardware processor is configured to switch from operating in a first method among the plurality of methods to operating in a second method among the plurality of methods, on the basis of a relative position of a work target of the shovel.
