Clamshell with a Bite: Its Got Teeth!

The next time I dropped by Salisbury Beach State Reservation to see the progress on the north jetty, I found the toothless clamshell benched and a new clamshell in action. The new clamshell has a deeper bucket and has teeth on both halves of the clamshell. It was working far more effective. It was able to grab a decent load of stone each time.

You will notice in the opening scene of the video, the dump trucks are now driving further out on the the beach with their loads. The stones are now being dumped much closer to where the crane is picking them up.
