Heavy-haul Railway Maintenance And Repair

In order to ensure that the train can run safely, smoothly and uninterruptedly at the specified maximum speed, and that the railway transportation department can complete the passenger and cargo transportation tasks with good quality, the lines must be kept in good condition.

However, with the continuous rolling of locomotives and long-term train loads, the track geometry of the line is constantly changing, the subgrade and ballast bed are constantly deformed and sinking, and the rails, couplings, and sleepers are constantly worn, resulting in the technical status of the line equipment. deterioration. In order to keep the line in good condition for a long time and ensure the safe and stable operation of the train, the public works department must carry out maintenance and repair operations on it.

The main tasks of maintenance and repair include:

Oil lubrication and grinding of rails, overhaul and maintenance of turnouts,

 

Reinforcement and maintenance of ballast, roadbed, bridge and tunnel for replacement of supplementary ballast

etc……

At present, the road maintenance machinery commonly used in heavy haul railways is divided into overhaul machinery, maintenance machinery, inspection machinery and repair machinery.

It is specifically divided into large-scale cleaning machines and supporting maintenance machinery, rail grinding vehicles, rail flaw detection vehicles, track inspection vehicles and other road maintenance machinery, as well as line tamping vehicles, ballast cleaning and screening vehicles, line power stabilization vehicles, and slope shaping vehicles. , turnout tamping vehicle, line overhaul vehicle, etc.

With these devices you can

Greatly improve operation efficiency and maintenance quality,

Thereby improving the quality of the line,

Ensure safe transportation!
