Overhead Crane Rails Introduction

Crane rails occupy an important place in the rail industry, and their special design enables them to withstand high lateral loads and ensure the stability and safety of the crane. Dafang Crane is focused on providing high quality crane rail solutions to meet the needs of a wide range of industrial applications. Our rail products are carefully designed and manufactured to:

• Wide base design: to ensure the stability of the track under high lateral load, avoiding the deformation or damage of the track.
• Thickened web: improves the carrying capacity of the track, especially suitable for the use of heavy cranes.
• Special profiles: We provide a variety of heavy-duty crane rail profiles, including Chinese standard GB crane rails, German standard DIN crane rails, British standard BS crane rails, European standard EN crane rails, Japanese standard JIS crane rails, Australian standard AS crane rails, and special tracks customized for specific projects to meet the needs of different regions and industries.
• Customized services: According to the specific needs of our customers, we provide tailor-made solutions to ensure the best crane rails performance for each project.

Dafang Crane is committed to providing the most reliable crane rail products to help customers improve operational efficiency and ensure project safety. We not only provide quality products, but also provide professional technical support and consulting services to ensure that every project can be carried out smoothly. To choose Dafang Crane company is to choose high quality and excellent service.

German Standard DIN Crane Rails

A class of short and squat rails was developed in Europe and is described by the DIN 536 Standard. Commonly referred to as “DIN” rails, these are found worldwide and are, by volume, the most widely used crane rails in the world.

DIN rails are available in a range of sizes, from A45 (22.1 kg/m) to A150 (150.3 kg/m), and can meet the requirements of most crane rail systems. Unlike the names of many other rails, the nomenclature for DIN rails describes the width of the head and not its weight (for example, A45 has a 45mm wide head).

Each DIN rail profile is characterized by a low center of gravity, a relatively wide and robust head, and a very wide web and base. Designed to be installed on beams or foundations that offer continuous support, their lower height can be a boon for installations where overhead clearance is important. Their width and blocky shapes are extremely stable, ideal for crane applications.

The DIN 536 standard defines two steel grades: one with a tensile strength greater than 690 MPa and one greater than 880 MPa. Over time, different mills have come to use different jargon to represent these grades. Wirth Rail’s DIN rail supplier, ArcelorMittal, uses the names 70 kg & 90 kg. (aside: 880 MPa = 880 N/mm2 ˜ ( 90 kg x gravitational constant 9.81m/s2 )/mm2).

Two additional grades are found in Europe but are not described in the DIN 536 specification. The steel is alloyed with Chromium and Vanadium to achieve a tensile strength greater than 1080 MPa. ArcelorMittal refers to these by the names 110 CrV and R340 in its literature.

European heavy crane rails are finished in standard lengths of 9, 10, 12, 15 and 18 metres (≈ 30, 33, 39, 49 and 59 ft). Other lengths can be supplied by special request. The stocky shapes of these rails make drilling impractical. Square-finished ends are standard with Mitre cuts also available.

All Crane rails are produced and tested to stringent metallurgical quality standards. They are offered in multiple grades which improve the rail’s load-bearing capabilities while reducing in-service wear rates. The grading of Crane Rails depends on their origins: in North America, Brinell Hardness is used for grading purposes, whereas the European standards focus on Tensile Strength. There is an approximate correlation between the two systems.

Crane rails are available in a variety of lengths, ranging from 6 meters to 12 meters. Other lengths are available upon request.

We produce steel of various quality and specifications according to the requirements of our customers to suit the application of crane wheels and the expected life of the system.

Unfortunately, not all crane rail sections are readily available as the most common rail sections are being rolled. Sometimes, if a rail section is not available and no rolling date is scheduled, Dafang Crane will work with you to suggest an alternative section with similar characteristics.

Chinese Standard GB Crane Rails

Crane rail is a special type of steel rail. Crane rail is different from ordinary steel rail because it can be applied to crane rail. Depending on the type and purpose of the crane, crane rails can be divided into ordinary rail rails, special crane rails (steel crane rails), or square and rectangular section rails.

The ground crane mainly adopts the ordinary crane track; Bridge cranes often use special crane tracks, and there are other tracks to choose from. The trolley also has a similar type of track, which is fixed to the bridge or horizontal arm of the crane. The flange of the steel beam can also be used as the track of the car. The foundation of the crane track is concrete, reinforced concrete, slag lining and metal beams.

• The straightness of the track line, the gauge, the height difference between the two rails, etc., have a great impact on the operating performance of the crane, so it must be installed in accordance with the accuracy required by the specification.
• The track should be firmly fixed to prevent sliding along the foundation.
• The track may be deformed during use, and the rail head is easy to wear, so the track and the foundation should be disassembled with track bolts or other track fasteners as far as possible, so as to facilitate adjustment and replacement.
