That's essentially what I had planned to do, but have two chains on the outside of flights rather than one in the centre. I think if you put something heavy on it or something got hung up somehow it would damage itself quickly like that

The center chain design lets the flights move a long way before they bend. The hydraulic detent can kick out when relief pressure is surpassed and lastly they had a shear pin in the sprocket driving(pulling) the chain. The pulling(top mount) rather than pushing is important I think. I broke 1 shear pin in two years and had it stall or kick the detent occasionally. Generally if there was a issue it happened when something hung and went down to the lower sprocket.

I wouldn't be so much worried about the flight bending as torquing on the chain and bending links or rollers, damaging the chain. I don't imagine it will be so easy to replace.

That is a good idea having a shear pin anyway I'll try and encorporate that.

Nothing to worry about with '78' chain, one strand down the middle. We never bothered with shear pins. Hyd. relief adjustment on hyd. conveyer and the other is belt drive that would slip in a jam. Also need flared 'side boards' so wood will spill rather jam like on boxed sides. Drive sprocket always on top pulling load. I don't do the nice work Josh does but through trial and error have figured what works.

my conveyor is a 12 V gear reduced tarp motor and has a 50 amp auto-resettable breaker, so if it jams the current kicks the breaker off temporarily.
