An overhead conveyor, components therefor and method for making same, in which the conveyor chain has a nominal pitch "X," but a maximum allowable chain pull value which is equal to or greater than the maximum allowable chain pull value for a chain having a nominal pitch of X + 1. Trolleys can be attached to the chain at intervals which differ from the intervals of a chain with pitch of X + 1. Fewer synchronized drives are required for driving longer chains. A lower pitch chain can be used to drive larger trolleys, without sacrificing the maximum allowable chain pull value always used in conjunction with the larger trolley. |
