PURPOSE:To enable the measuring value of an external force to be effectively utilized for palnning of a front part, by a method wherein an external force, exerted on a bucket, is detected through utilization of a bucket for measurement to which 2 divided units are connected through a 3-component load cell. CONSTITUTION:Mounting metals 13 and 14, being mounted to an arm mounting part side upper unit 11 and a ground contact part side lower unit 12, respectively, into which the unit is divided, are intercoupled through a 3-component load cell 15 which is provided at the inner side of its frame body with strain gauges, and measures a horizontal external force, a vertical external force, and twist moment, exerted between members positioned facing each other, to output them as a voltage value. The external force, detected by the load cell 15, produces a force which is exerted on the unit 12 on a basis of the unit 11, and an external force, exerted on the bucket, can be measured independently from movement of the front part of a shovel. This enables an external force to be measured easily and with high precision. |
