Common Defects Found During Crane Rail Inspections And How To Fix Them

Crane rail inspections are very important for ensuring that overhead cranes stay safe and functional over time. Wear and tear, natural, and sometimes improper installation cause a defect over time, which definitely deteriorates the performance. Therefore, in this blog, we have detailed the most common defects observed after rail inspections, their implications, and solutions to fix them. Here at Dorance, we are professional and dedicated to excellence in ensuring your crane rail systems will perform at an optimal level.

Common Crane Rail Defects

1. Rail Misalignment

Rail misalignment occurs because of wrong installation, thermal expansion, and heavy loads. The misaligned rails cause unequal wheel wear as well as enhance stress on the crane components with the possibility of an operational failure.

Solution:

We use advanced instruments like topographic surveys for accurate rail alignment. We correctly align the rail by adjusting, high-performance grout application, and rail clips' installation to resist further misalignment.

2. Wear and Pitting on Rail Surfaces

Continuous movement of the wheel and heavy loads result in surface wear and pitting on the rail head. This defect reduces the efficiency of load distribution and increases the chances of derailment.

Solution:

 

Regular resurfacing and grinding of the rail can restore smoothness. We apply specialized maintenance techniques and durable rail pads to reduce friction and wear.

3. Cracks and Fractures

Cracks in crane rails are due to overstress, material fatigue, or manufacturing imperfections. This may result in rail failure with resultant downtime.

Solution:

We offer aluminothermic welding solutions for crack or fracture repairs that produce smooth butt welds eliminating wheel damage with structural integrity assured for the rail.

4. Rail Corrosion

Corrosion is a widespread concern in damp, wet, and coastal conditions; moisture and sea salt undermine structural strength in these areas.

Solution:

Preventive measures include applying protective coatings and installing corrosion-resistant materials. We specialize in supplying rails made with high-strength steel alloys, ensuring longevity even in extreme conditions.

5. Loose or Damaged Rail Fastening Systems

Faulty or loose clips and pads can cause rail instability, leading to vibration, noise, and misalignment.

Solution:

 

We provide high-quality, bolted, or welded rail clips with capacities ranging from 50 kN to 200 kN. Our continuous and discontinuous pads offer superior resistance to oil, temperature, and environmental stress.

6. Improper Rail Joints

Poorly joined rails cause uneven transitions, leading to increased vibration, wear, and noise.

Solution:

 

We use aluminothermic welding to create seamless joints that eliminate unevenness. This process ensures smoother transitions and reduces wear on crane components.

7. Undersized or Overloaded Rails

Using rails that do not match the crane's load requirements can lead to deformation and safety risks.

Solution:

 

Our team of engineers calculates the optimal rail specifications for your application, ensuring the system meets load requirements without overloading.
