Second grab attachment parts 26b to attach a total of three second grabs 3b are formed at three points between adjacent ones of the first grab attachment parts 26a. A grab bucket enables a change in grab mode from a first mode equipped with only the total of three first grabs 3a to be suitable for the cargo handling of a revetment block to a second mode equipped with a total of six grabs 3 of the first grabs 3a and the second grabs 3b to be suitable for the cargo handling of a bulk material such as a stone material by attaching/detaching the second grabs 3b to/from the second grab attachment parts 26b.</p> |
