Taking the Crane Barge and the Stone Scowl out to the Jetty

The crane barge and stone scowls are sometimes taken out to the Salisbury jetty separately. They are now bringing one of the cranes out around the tip of the jetty to work on the ocean side of it. Previously, the cranes had been anchored along the Merrimack River side of jetty. You will see the video of the crane barge, there are two different size grabbles sitting on deck. One is red (left) and other is blue (right). I have seen both being used fairly regularly.

While the barge is being moved out, the crane's lift cable is attached to one of the anchor posts. It is standard procedure to keep it attach to the last anchor posted pulled up while docked along the construction staging area. Once the barge is in position on the jetty, the anchor post is lowered. The second part of the video shows two tug boats working together to turn a stone scowl in the river and bring it out to the crane.

A portable metal gangway is lowered into position. It allows the crew to access the jetty.
