CR73 Rail
CR73 rail is named for its 73.3 kg/m weight and features a wide head profile tailored for crane operation. Manufactured by hot rolling from high-strength steel like U71Mn, it offers good toughness and stability. With a cross-section height slightly shorter than its base width and a broader head than standard rails, CR73 is designed to balance wheel load support and vibration resistance. It is well-suited for medium-duty cranes in warehouses, workshops, and light industrial facilities.

CR73 Rail Material Grade
Made from high-strength U71Mn steel, engineered for excellent wear resistance and impact durability in crane rail applications.
CR73 Rails Project Applications
Indoor Cranes
Suitable for medium-duty overhead cranes in workshops, CR73 rails ensure smooth travel and operational safety. Their wide head design distributes wheel pressure effectively, reducing wear in high-use indoor environments.
Light Industry
CR73 rails support cranes in light manufacturing setups, where stability and moderate strength are essential. Their structure allows reliable load transfer while minimizing floor vibrations and noise.
Storage Zones
Ideal for use in storage yards or sheltered loading zones, these rails handle moderate crane loads without frequent maintenance, ensuring long-term reliability in logistics and warehousing.
Customization Options
Rail Bending
We offer custom hot or cold rail bending to match project layouts. Precise shaping ensures a perfect fit for curves. Curvature is tailored to drawing or site needs.
Drilling Service
Drilling is fully customized to your fastening system. We handle fishplate holes or web holes for forming bolts.Hole size and spacing are matched to your drawing.
Corrosion Protection
Rails can be treated with paint, zinc coating, or anti-rust oil. Each option suits different working environments.We select the best protection method for your usage scenario.
End & Joint Cuttingg
We cut angled ends, bevels, or special joints based on your assembly plan. Profiles support precise rail connections. Every cut is based on your drawing or on-site need.
Packaging & Delivery Assurance for CR73 Rails
- Standard export-grade packaging is adopted to protect all shipments during international transport. Each rail is fastened with steel straps and stabilized with wooden blocks inside the container. Waterproof materials can also be applied for additional moisture protection upon request.
- Accessories and structural components are packed in non-fumigated wooden crates and fixed in position to prevent shifting or impact damage en route.
- Our logistics team has substantial experience shipping to Africa, South America, and Central Asia, ensuring prompt and damage-free delivery to your destination.
