The forged rivet-less chain is the most often used on trolley conveyors. It has a high strength-to-weight ratio, with capability to flex both horizontally and vertically.
Use of various special chain pins and attachments which operate without trolley support can greatly increase the number of parts conveyed. Most attachments illustrated are designed to replace the standard pin. When used as intermediate load supports for overhead trolley applications, care should be taken to assure that the loads are light enough to avoid chain sag and binding.
The master pin shown is a substitute for the standard chain pin and allows chain assembly or dis-assembly under tension. Chain-on-edge floor type attachments are also included in the grouping below.
