PATENTED CHAIN WATCH
As the chain stretches or wears through time, the chain pitch may not correspond to the drive wheel pitch and the entire load is pulled with one or two links at a time. In this case, the chain must be kept tight as it easily jumps off the drive wheel. Finnchain system’s Chain Watch removes this problem; Chain Watch mechanically prevents the chain from jumping off the drive wheel. An electrical switch can also be connected to the Chain Watch, which shuts off the motor in the event of an overload.
