A conveyor chain for a travel way on which an operator and/or a work carriage are reliably moved in a nonskid manner. The conveyor chain has a series of modules, each with a nonskid material loaded upper surface with front and rear hinge portions for connecting the modules to each other by connecting pins. The nonskid material loaded upper surface has hollows with the hollow surfaces recessed below the upper surface. The upper surface includes a number of supporting ribs project upwardly from the hollow surfaces and terminate flush with the upper surface, so that the transfer of the work carriage is easy and a back bend radius is decreased. Miniaturization and simplification of the conveyor are attained.
