Barge-Mounted Clamshell Crane

[Jared]

The power tagline on a clamshell is also used for the dipper trip when the machine is set up as a shovel. It usually runs off the end of one of the drum shafts and has a clutch that is set to drag a little bit to keep a constant pull. When you want to trip the dipper or pull on the clam you fully engage the clutch.

I haven't made any progress on the crane for a while. Last winter when I was unemployed I had piles of time and no money, and now that I have a job I have money and no time and energy. But anyway, today it was time to refill the laundry detergent box so I put the clam bucket on the job. It took about an hour and a half to get it done. I shot a little video. I have a longer one if demand is there.
