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.
- Excellent Load Support
- Durable & Stable Performance
- Ideal for Crane Systems

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.
Packaging & Delivery Assurance for CR73 Crane Rail
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.

FAQ—Customer Concerns for CR73 Crane Rail
How do I choose CR73 rail for my crane runway?
CR73 rail selection should be based on crane wheel loads, wheel arrangement, runway structure, operating conditions, and the required rail fastening system. The 73.3 kg/m profile is commonly specified for heavy-duty crane applications where a dedicated crane rail section is required. If you provide the crane wheel load, wheel spacing, rail span, and runway details, Glory Track can help confirm whether CR73 is suitable for your application.
Can I buy CR73 rail with matching clips and fastening components?
Yes. CR73 rail can be supplied together with matching fastening components, depending on the runway structure and installation method. Glory Track can provide compatible rail clips, fishplates, rail pads, and other fastening components as required. For projects with specific fixing requirements, send the rail drawing and runway details so the fastening configuration can be reviewed before quotation.
Can CR73 rail be cut, drilled, or bent before delivery?
Yes. CR73 rail can be processed before shipment according to project requirements. Available services may include cut-to-length, drilling, rail bending, and end or joint preparation. Processing details should be confirmed against the project drawings and installation requirements before production. You can include the required dimensions, hole pattern, bending radius, or drawing when requesting a quotation.
What rail length can I order for CR73?
CR73 rail is currently listed in 12 m lengths, with custom cutting available for project-specific requirements. If shorter sections are needed for replacement work, installation constraints, or container loading, the required rail length can be confirmed before production. Include the required length and total quantity when requesting a quotation.
Can you quote CR73 rail based on my drawings or existing rail dimensions?
Yes. Glory Track can review project drawings, rail profile dimensions, and existing specifications when preparing a CR73 rail quotation. This is particularly useful for replacement projects or systems with customized drilling, bending, or other customized requirements. Send the available drawings or rail dimensions together with the required quantity and delivery destination, and the quotation can be prepared based on the project requirements.
What information is needed to get a CR73 rail quotation?
To request a CR73 rail quotation, send the required quantity, rail length, delivery destination, material requirements, and any processing specifications. Project drawings or existing rail dimensions are also helpful for customized orders. Glory Track can quote CR73 rail together with compatible fastening components when required, allowing customers to source the rail and related components as one package. You can contact our team with your project details for a tailored quotation.
