The chain that keeps jumping
Case elevator: incline lug-chain drive · 10 min
The case elevator's lug chain jumped teeth under load again this week. The chain that just came off is on the bench and its replacement is fitted. Every replacement runs quiet at first, then the jumping comes back, and the crib keeps issuing chains. A chain drive that eats chains this fast is being fed to something. Read the old chain, then find what keeps eating them, and commit.
