Forged chain link DIN series

conveyor chainfor drag chains

Overview
DIN 745 elevator chains and DIN 5699 scraper links: forged chain links designed for bucket elevators (vertical) and scraper conveyors (flat/inclined). Engineered for uniform load distribution, simplified link replacement and wear resistance under shock and cyclic loading.

Introduction
Item | DIN 745 bucket chain link | DIN 5699 scraper chain link
Typical application | Vertical bucket elevators | Flat or inclined scraper conveyors
Basic design | Round-steel, short-pitch chain with widened, drilled sidebars to bolt buckets | Flat-link chain with thick sidebars to 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 or fixed with connectors
Key advantages | Even load distribution, quick link replacement, high shock resistance | Wide wear face, strong bending/torsion resistance, suited for long scraper runs
Frequent industries | Cement, grain, fertilizer vertical lifts | Metallurgy, coke plants, waste incineration, ash conveying

Parameter (overview)
The product page includes detailed parameter matrices listing available pitches, weight per link, bolt/plate hole sizes, key diameters and MBK (kN) values. Typical bolt sizes range from M10 to M36 depending on pitch and chain size. Matrices provide numerical tables of: pitch (mm), weight (kg per link), key diameters (d1, d2, d3), plate dimensions (h, a, l, L, D), sectional sizes (S, B) and MBK (kN).

Standards & Notes
Manufactured to match DIN 745 (bucket elevator chains) and DIN 5699 (scraper conveyor chains) dimensional and functional requirements. Distinctions between vertical elevator use and flat/inclined scraper conveyors are described above; consult parameter matrices to select the correct pitch and bolt size for your application.

Technical specifications

• Standards: DIN 745 and DIN 5699 (distinct designs for elevator buckets vs scraper flights).
• Typical applications: vertical bucket elevators (DIN 745) and flat/inclined scraper conveyors (DIN 5699).
• Design: DIN 745 — round-steel short-pitch chain with widened, drilled sidebars for bolted buckets; DIN 5699 — flat-link chain with thick sidebars for welded or bolted scraper flights.
• Common pitches: examples include 125 mm, 142 mm, 160 mm, 177 mm, 200 mm, 250 mm (full pitch matrix provided on the page).
• Available bolt/plate hole sizes: ranges from M10 to M36 depending on pitch/chain size.
• Parameters provided: pitch (mm), weight per link (kg), d1/d2/d3 diameters, plate dimensions (h, a, l, L, D), sectional sizes (S, B) and MBK (kN) for each configuration.
• Advantages: even load distribution, quick link replacement, high shock resistance (DIN 745); wide wear face, strong bending/torsion resistance, suited to long scraper runs (DIN 5699).
• Frequent industries: cement, grain and fertilizer handling (vertical lifts); metallurgy, coke plants, waste incineration and ash conveying (scrapers).
