QU100 Rail
Product Overview
QU100 is a rail specifically engineered for heavy crane applications. Designed around three core promises — High Strength, Superior Wear Resistance, and Exceptional Stability — QU100 is the preferred rail solution for heavy-duty track systems in large ports, metallurgical plants, mines, and heavy manufacturing facilities. It is optimized for crane systems in the 80–200 ton capacity range.
Core Advantage
Superior load capacity: A large cross-section combined with high-strength steel enables stable handling of wheel loads well over 100 tons — suitable for 80–200 ton cranes.
Outstanding wear resistance: The rail head undergoes professional quenching to reach HB301–388, delivering excellent fatigue and wear performance in high-duty cycles and long service life.
Exceptional dimensional stability: Optimized web thickness and cross-sectional geometry yield high bending resistance and impact tolerance, maintaining track accuracy under thermal cycles and heavy loads.
Harsh-environment resilience: Optimized manganese content and material treatment resist salt spray, dust, and elevated temperatures typically found in ports, mines, and metallurgical environments.

Installation & Selection Guide
Installation highlights
Fixing method: Recommended welded clamp-type press-fastener system with dedicated clamping plates, anchors, and shims to ensure tight contact between rail and foundation.
Joint treatment: Welding of rail joints is recommended to minimize gaps and reduce dynamic impacts for smoother crane travel.
Tolerance & alignment: Post-installation tolerances — rail height deviation ≤ ±0.5 mm; base width deviation ≤ ±1 mm; straightness deviation ≤ 3 mm per 10 m.
Ordering & Services
Minimum order quantity: 10 tonnes
Customization: Batch customization available for length (6.0–12.5 m).
Technical services: Complimentary selection consultation, installation guidance, and full quality inspection reports
Delivery: Ships with factory inspection records and packaged per customer requirements
