High load conveyor chain and method

摘要

An 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.

主权项

1. 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; said conveyor chain having pairs of spaced side links joining alternating center links, in which said center links have spaced center link legs which are 50-75% taller in a direction perpendicular to the length of the chain, and 25-50% thicker, than the center link legs of industry standard chains having the same pitch; and said side links have spaced legs which are 25-50% taller in a direction perpendicular to the length of the chain, and 25-50% thicker, than the side link legs of industry standard chains having the same pitch; said nominal pitch being 2 inches, and said side links and center links being joined by ½ inch diameter pins.
