About A75 crane rails

The A75 crane rail is a type of steel rail designed to provide a stable track for industrial cranes to move along. Its name comes from its weight per meter, which is 75 kilograms. The A75 crane rail has a flat bottom and an asymmetrical profile, which allows it to support heavy loads and withstand the lateral forces generated by the movement of the crane.

Compared to other crane rails, the A75 crane rail has a higher load-bearing capacity, making it suitable for heavy-duty applications. It is also more durable and resistant to wear and tear, thanks to its hardened steel composition. The A75 crane rail is often used in ports and terminals, where container gantry cranes need to move large and heavy loads.

The standardized dimensions of the A75 crane rail are defined by the European DIN 536 standard. The rail has a width of 150 millimeters, a height of 150 millimeters, and a length of 12 meters. Its weight per meter is 75 kilograms, and it has a minimum tensile strength of 700 N/mm². These standardized dimensions ensure that the A75 crane rail is compatible with a wide range of industrial cranes and other equipment, making it a versatile and widely used type of crane rail.

Design and Manufacturing of A75 Crane Rails

Designing and manufacturing A75 crane rails requires careful consideration of various factors to ensure that they meet the necessary safety and performance standards. The design process begins with analyzing the expected load and movement of the crane to determine the appropriate rail profile and dimensions. The rail must be able to support the weight of the crane and its load, while also withstanding lateral and vertical forces.

The manufacturing process for A75 crane rails typically involves hot rolling, a process that involves heating steel billets to a high temperature and then passing them through a series of rollers to shape them into the desired rail profile. During this process, the steel is hardened to increase its strength and durability. Once the rails are formed, they undergo various finishing processes, including straightening, cutting, and drilling, to prepare them for installation.

The materials used in the production of A75 crane rails are typically high-quality steel alloys, chosen for their strength, durability, and resistance to wear and tear. The most common material used is high carbon steel, which contains a higher percentage of carbon than regular steel and has a greater tensile strength. Other materials used in the production of A75 crane rails include manganese steel and alloy steel, which offer similar properties to high carbon steel.

Quality control measures are crucial during the manufacturing process to ensure that A75 crane rails meet the necessary safety and performance standards. These measures include non-destructive testing to detect any defects in the steel, such as cracks or impurities, and hardness testing to ensure that the rails have the required strength and durability. The rails are also inspected for dimensional accuracy and surface finish to ensure that they are compatible with other equipment and can be installed and used safely.

Applications of A75 Crane Rails

A75 crane rails are widely used in various industrial sectors that require the movement of heavy loads. They are especially popular in ports, terminals, and factories, where large cranes need to move containers, heavy machinery, and other bulky items. The transportation industry also uses A75 crane rails for the movement of cargo in ports and rail yards.

A variety of cranes use A75 crane rails, including container gantry cranes, ship-to-shore cranes, and rail-mounted gantry cranes. These cranes are essential for the efficient movement of cargo in ports and terminals, and the A75 crane rail provides a stable track for their movement.

The load capacity of A75 crane rails is one of their key features that affect their applications. With a load-bearing capacity of up to 15 tons per meter, A75 crane rails are ideal for heavy-duty applications that require the movement of large and heavy loads. They are also suitable for applications that require high-speed movements, as their flat bottom and asymmetrical profile allow for smooth and stable crane movement.

There are many benefits to using A75 crane rails in various applications. First and foremost, they provide a stable and safe track for cranes to move along, reducing the risk of accidents and equipment damage. They also offer a long service life due to their durable and wear-resistant properties. Additionally, A75 crane rails are easy to install and maintain, requiring minimal upkeep and repair.

Maintenance Requirements for A75 Crane Rails

Maintenance is an essential aspect of ensuring the longevity and safe operation of A75 crane rails. Like all machinery, crane rails can experience wear and tear, as well as damage due to various factors such as environmental conditions, heavy loads, and regular usage. Proper maintenance procedures can help to identify and address issues before they become more severe and result in costly repairs or accidents.

There are several types of damage that can occur to A75 crane rails, including wear, cracking, and deformation. Wear can occur due to regular usage, while cracking and deformation can occur due to heavy loads or environmental conditions such as temperature changes. The causes of damage to crane rails can also include improper installation, insufficient lubrication, or inadequate load distribution.

To prevent damage and ensure safe operation, A75 crane rails require regular inspections and maintenance. The maintenance procedures required for A75 crane rails include cleaning, lubrication, and regular inspection for signs of wear or damage. Regular inspections should be performed by qualified personnel and include visual inspections as well as non-destructive testing methods such as ultrasonic testing.

Regular maintenance is crucial for the longevity of A75 crane rails. Neglecting maintenance procedures can lead to more severe damage and result in costly repairs or replacements. Regular maintenance can also prevent accidents and ensure the safety of personnel and equipment. Proper maintenance can also increase the efficiency of crane operations, reducing downtime and improving productivity.


In conclusion, this article provided an overview of A75 crane rails, including their characteristics, design and manufacturing, applications, and maintenance requirements. A75 crane rails are widely used in various industries and have a high load capacity, making them ideal for heavy-duty operations. It is crucial to understand their maintenance requirements to ensure their longevity and safe operation. Regular inspections and maintenance procedures can prevent accidents and equipment damage, reducing downtime and improving productivity.
