QU80 Rail
Product Overview
The QU80 crane rail is a premium-grade steel rail engineered for demanding industrial environments, offering a balance of strength, durability, and cost-effectiveness. It is engineered for medium-to-heavy load applications, compliant with GOST R 53866-2010 and EN 13674-1. With a theoretical weight of 63.69 kg/m, it balances strength and flexibility for industrial cranes and material handling systems.
Key features
Profile Design:
Head width: 80 mm
Rail height: 130 mm
Base width: 130 mm
Web thickness: 32 mm
Weight: 63.69 kg/m.
Manufactured from U71Mn high-strength steel (0.65–0.77% C, 1.1–1.5% Mn) , it delivers exceptional tensile strength (880 MPa) and resistance to abrasion, impact, and fatigue. Its wide head (80 mm) and thick web (32 mm) ensure optimal load distribution and long-term reliability.
U71Mn Steel Construction: Combines high hardness (260–300 HB) with toughness, ensuring extended service life in harsh conditions .
Surface Finish: Hot-rolled or galvanized options for corrosion resistance in marine and industrial settings.
Compatibility: Works with standard rail clamps, rubber pads, and fish plates for seamless installation .
Applications
Load Capacity: Supports medium-to-heavy loads, ideal for cranes in factories, ports, and shipyards.
Ports & Terminals: Handles container cranes and heavy lifting equipment.
Steel Mills: Used in overhead crane systems for material handling.
Mining & Quarries: Supports bulk material transport in rugged environments.
Construction: Temporary rail systems for tower cranes and precast concrete yards.
