Hay elevator motor sprocket

A friend bought a hay elevator and I gave him an old engine and belt pulleys to run it, he is using it for cinder block and bricks and sacks of mortar etc. He said the belts don't last and he wants to go to chain and sprocket, i'm sure he is loading it heavy, he wants to use a centrifugal clutch on the motor end but it seems like that would not be needed, he wants to be able to pause the eloevator. I would think an idler sprocket would be better but maybe not. Anyone ever rig one up with idler or centrifugal clutch? Thanks.
 
He will need the centrifugal clutch. I had just a normal hay elevator years ago that had a chain drive with a dog clutch on the elevator end. It was very hard to get started. The extra weight of the chain and drive pulley made it hard to start. You could take the chain off and it would fire right up. Put the chain on a crank your self silly.
 
He wants to run it all the time? Very dangerous, has to be a way to stop the elevator fast if something goes wrong. And I would not trust a centrifugal clutch for that as if something would grab that clutch could not release. If have to use a chain drive at least get an engine with a built in disk cluch.
