CRATOS® Technology for Energy Generation

The CRATOS® system is RUD's integrated solution for fuel feeding and ash removal in fossil-fueled, waste-to-energy, and biomass power plants. It combines engineering, product, and service concepts to deliver reliable, durable conveyor systems optimized for harsh operating conditions.

Engineering Concept

• Customized calculation, planning, and consulting tailored to specific plant requirements.

Product Concept

• Use of high-quality round steel chains engineered for extreme conveyor environments.

Service Concept

• On-site measurement, maintenance, documentation, and installation of optimal chains and accessories.

Historical Milestones

• 1875: Company founded as a spin-off from ERLAU AG.
• 1951: Developed the first case-hardened round steel chain worldwide.
• 1965-2012: Advanced chain qualities, dry ash removal systems, and biogas substrate conveyors introduced.

CRATOS® Conveyor Systems

Designed for fuel handling (e.g., coal feeding) and ash removal, CRATOS® conveyors feature widths from 0.8 to 1.8 meters and speeds of 0.1 to 0.3 m/s for non-abrasive materials. System types include strand conveyors, bunker discharge conveyors, and scraper chains with transport capacities ranging from 50 to over 150 tons per hour.

Dry Ash Removal Systems

• Innovative plate band systems replace traditional trough scraping, offering robust construction, continuous plate coverage, reduced polygon effect, and compact design.

CRATOS® System Components

Chains

Manufactured from special alloys with high core toughness, these chains provide high breaking strength, resistance to brittle fracture, fatigue resistance, and optimized geometry for durability. Tensile strengths range approximately from 60 to over 80 N/mm².

Chain Wheels

Made from case-hardened steel castings, available in single or multi-part designs with replaceable wear-resistant segments, precisely matched to chain geometry to maximize wear resistance and strength.

Chain Rollers and Idlers

Inductively hardened running surfaces designed for heavy-duty use, available in various types to suit different CRATOS® attachments, ensuring extended service life.

Attachments and Scraper Blades

Custom-engineered, robust, and easy-to-install solutions for diverse conveyor tasks, compatible with single and multi-strand conveyors.

Chain Links and Locks

Highly wear-resistant hardened locks designed for easy assembly and reliable operation across various conveyor configurations.

Product Quality and Comparison

CRATOS® premium chains outperform standard mining chains in wear resistance, longevity, operational reliability, breaking strength, and fracture safety, while maintaining energy efficiency and competitive price-performance ratios.
