Forged chain link

flat toproundconveyor chain

Introduction
Item | DIN 745 Bucket Chain Link | DIN 5699 Bucket Chain Link
Typical Application | Vertical bucket elevators | Flat or inclined scraper conveyors
Basic Design | Round-steel, short-pitch chain; each link carries widened sidebars drilled for bucket bolts | Flat-link chain; thick sidebars accept welded or bolted scraper flights
Common Pitches | 125 mm, 160 mm, 200 mm | 142 mm, 177 mm, 250 mm
Mounting Method | Buckets bolted to pre-drilled sidebar holes | Scrapers welded directly or fixed with connectors
Key Advantages | Even load distribution, fast link replacement, high shock resistance | Wide wear face, strong against bending/torsion, ideal for long scraper runs
Frequent Industries | Cement, grain, fertilizer vertical lifts | Metallurgy, coke plants, waste incineration, ash conveying

Overview
DIN 745 elevator chains & DIN 5699 scraper links—precision forged for vertical and flat conveyor runs.
