Abstract
AD overhead conveyor, components therefor and method for making same, in which the conveyor chain has a nominal pitch “X,” bit 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.
Claims23
An overhead conveyor chain having a nominal pitch of “X” inches, with 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 inches.
An overhead conveyor comprising:
- a driven conveyor chain having a nominal pitch of “X” inches;
- a beam track having a nominal height of X+1 inches;
- trolleys having nominal X+1 inch wheel diameter riding on said track and attached to said driven conveyor chain;
- and said driven conveyor chain having 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 inches.
A method of constructing an overhead conveyor comprising:
- providing as driven conveyor chain having a nominal pitch of “X” inches, having 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 inches providing a beam track having a nominal height of X+1 inches;
- mounting trolleys having nominal X+1 inch wheel diameter to ride on said track and attaching said trolleys to said driven conveyor chain.
