Swival head for a clam, pulp loader

[joes_427_vette]

Thinking about constructing a pulp trailer with a loading boom. Anyone know where a hydraulic swival could be purchased to operate a clam ? I have seen a unit made in Canada that is pretty compact. A new one may be quite costly depending on size and capacity.

I have a friend that built a whole grapple for his homebuilt knuckle boom he put on his work barge. He made the swivel out of a set of tapered roller bearings off 2 truck hubs and mounted a hydraulic motor to the die with a sprocket on the clamp frame. he then cut the center out of a sprock and mouned it the the eye that the shaft wit hthe bearings mounted on the boom. I have a pic on my old computer Ill see if my wife can retriece it on a memory card.
He made the grapple with one cylinder that opened and closed the jaws without a linkage or a flow divider. he used a set of stops. His head wasnt a 360 continuos rotation. He added a couple feet of hoses for both functions in a plastic coil that held them out of the way and let it go 360 each way. They tore out old docks and used it to handle Schedule 40 and 80 6 and 8 inch pipes 25 feet long.

I built a loader for my splitter using a steering cylinder and # 40 chain for the head swivel, mount the cylinder horizontal wrap chain around bushing and hook to ends of the ram twists 180+ degrees allowing you to grab wood at any orientation I could take pic if you want

Thanks for the info. The Hawk series looks great but weighs almost 1100 #. A few more responses on the home built models will probably be the winner.

Slick !!

That looks simple yet effective. Sizzami; did you build this?

See post #3 - yeah he did. Nice job!

I wonder how it would work to put a hydraulic motor on a hollow shaft gear box? Might want a slip clutch on the output to protect the gears.
