In Dec. 2015, One of our old client ask us whether our long reach boom armwith standard bucket can grab and carry big boulders, in our experience, we think standard bucket is not suitable for material handling, we suggest rock grapple, which has two claws can open and close, one claw is fixed by a steel rod on bottom side of dipper, another claw is driven by bucket cylinder, maximum opening of this rock grapple is 1.9m that's wide enough to grab stone.
