Document Type and Number:
Japanese Patent JP6645996
Kind Code:
B2
Abstract:
A load measurement unit (35) measures a transport article load when determination is made that a front work device (12) is performing a measurement operation. A remeasurement determination unit (36) determines the necessity of remeasuring the transport article load on the basis of the time that the front work device (12) measurement operation continued. When determination is made that remeasurement of the transport article load is required and determination is made that the front work device operation has stopped, a load remeasurement unit (38) measures the transport article load on the basis of the pressure of a boom cylinder and the orientation of the front work device. A display device (31) shows a prompt to the operator to stop the front work device (12) operation when determination is made that remeasurement of the transport article load is required.
