The barge cranes equipped with large grapples grab to stones and swing them over the stone scowls. Grabbing this multi-ton stone blocks can be a bit tricky sometimes. As the video shows, the crane operator has to make multiple attempts before he gets a firm grip on some of these stones. He repositions the grapple on the boulder until he can lift the stone without dropping. Sometimes the excavator needs to reposition the stone for the crane operator. Once crane grabs the stone, it is lifted and swung over to scowl. Care is taken not to get the boulder swinging while moving it.
