Crane rail installation - Standards and procedures

  Introduction to crane track installation

With the rapid development of modern logistics, greater demands are being placed on the logistics management of machinery and equipment. This is not just about transporting bits. Once heavy machinery or equipment has arrived at a facility, it also needs to be picked up, moved and set up appropriately. For these purposes, cranes come in very handy. As cranes play an important role, crane track installation also plays an important role in these industries. 

Crane track installation Techniques and standards

The accurate installation of crane rails is a primary requirement for this type of heavy machinery and related

industries. Selecting the most suitable track and securing it is a key issue in ensuring the integrity and longevity of the crane track system. At Yongyang, we have a reliable, skilled and experienced team to help you find the more suitable crane rails. But more on that later. Now let's talk more about crane rail installation standards. 

 

Crane rail installation has its own standards and techniques. For the most basic ones, technicians must inspect the rails, bolts, cleats etc. before the installation process and must replace them immediately if there are any cracks, corrosion or irregularities in the specifications. 


Standard specifications for crane rail installation

The standard specifications for the installation of crane rails are as follows.

Wear and defects should not exceed 3mm.

The horn should be in close contact with the main beam of the track and the crane. 

There should be no more than 20 horns per stage. 

The length of the horn should not exceed 100mm. 

The width should be between 10mm and 20mm 

wider than the bottom of the track. 

The distance between the two pieces should not exceed 200mm.  

The crossbeam must be firmly welded and the actual contact between the horn and the rail section should not be less than 60% of the nominal contact area. 

Rail joints can be made as straight or 45 degree angle joints. 

In cold regions, the gap between the joints must be between 1 and 2 mm during winter crane track installation. 

When the temperature is above 20 degrees Celsius, a clearance of between 4 and 6 mm should be considered. 

Stops must be installed at the end of the track to prevent the crane from derailing from both ends. 

The actual centre line of the track should not deviate from the geometric centre line of the track by more than 3mm.

Crane track installation procedures

It is well known that the crane track is a fundamental part of the crane installation procedure. Cranes require smooth and continuous rails to carry heavy loads and operate trouble-free. Accurate installation is imperative and the selection and fixing of the most suitable track is a key issue in ensuring the integrity and longevity of the crane track system. The best designs and materials are used in the installation process. The following procedures have been designed step by step by experts and skilled managers for the installation of crane rails.

Pre-embedded ground bolts were first drilled, which were used for the subsequent fixing of the iron baseplate.

The iron base plate is laid on the crane track bed and fixed with the foundation bolts.

The base of the crane rail clamp is welded to the iron base plate.

Crane rail welding is carried out using the hot rail welding method.

The crane rail alignment tool is used to align the rails so that the crane rail alignment tolerances meet the crane rail installation requirements.

The fixing of the crane rail clamps is competed by placing bolts in the base holes, installing rail clamps, slat washers and nuts to bring the crane rail clamps closer to the rail.

The crane rail installation procedure is complete.

Steelmaking Process (2)

8. Refining period: The process of steelmaking is carried out by slagging and other methods to remove some elements and compounds that are harmful to the quality of steel by chemical reaction into the gas phase or discharged into the slag to remove it from the molten steel. period. 9. Reduction period: In the ordinary power electric arc furnace steelmaking operation, the time from the completion of the slag slag to the tapping is usually called the reduction period. 10. Furnace refining: The steelmaking process of refining the molten steel in the steelmaking furnace (converter, electric furnace, etc.) to another vessel for refining, also called secondary metallurgy. The steelmaking process is therefore divided into two steps: primary refining and refining. 11. Steel liquid agitation: Stirring of molten steel through refining beyond the furnace. It homogenizes the molten steel composition and temperature and boosts metallurgical reactions. Most metallurgical reaction procedures a

What Are the Different Types of Steel Rails?

图片
Steel rails are an essential component of railway tracks, providing the necessary support for the movement of trains. These rails are manufactured from a variety of steel alloys and are designed to meet specific requirements of the railway track, such as durability, strength, and resistance to wear and tear. In this article, we will discuss the different  types of steel rails  used in railway tracks.   Carbon steel rails Carbon steel rails are the most common type of steel rails used in railway tracks. They are made from a combination of iron and carbon, with the latter content typically ranging from 0.7% to 1.5%. Carbon steel rails are affordable and can be easily manufactured in large quantities. However, they have a low resistance to wear and tear, which means that they need to be replaced frequently.   High-carbon steel rails High-carbon steel rails have a higher carbon content than standard carbon steel rails, typically ranging from 0.8% to 1.1%. This makes them harder and more re
