In July 2023, Glory Rail provided a comprehensive Brick Kiln Rail System to a major heavy industrial manufacturing company in Nigeria’s oil, gas, and energy sector. This client has long been engaged in the design and manufacture of pressure vessels, process skids, structural components for subsea production systems, large storage tanks, and offshore steel structures, and possesses extensive experience in heavy equipment manufacturing.
This project involved a heavy-duty bogie transport system for a brick kiln production line. The bogies are required to travel back and forth on tracks both inside and outside the kiln to transport brick blanks and finished bricks. The project not only required the system to meet the current 150-metric-ton load capacity but also needed to allow for future upgrades to a 400-metric-ton capacity, thereby placing higher demands on the track system’s load-bearing capacity, stability, and long-term reliability.
Customer Challenges
High-Temperature Operating Environment
The brick kiln was designed to operate at temperatures of up to 650°C.
Although this heat is not directly transferred to the wheels and rails due to the open space beneath the bogie, the rail system is continuously exposed to thermal radiation. Conventional rail fastening systems using rubber components may experience accelerated aging and reduced service life under such conditions.
The customer therefore required a durable fastening solution capable of withstanding long-term exposure to elevated temperatures while minimizing maintenance requirements.
Future Capacity Expansion
The original design load of the bogie system was approximately 150 tons, including:
- Bogie self-weight
- Kiln structure weight
- Refractory bricks
- Approximately 100 tons of transported products
However, the customer anticipated future operational upgrades and intended to increase the transportation capacity to approximately 400 tons. This meant the kiln rail system needed to be engineered with adequate safety margins and future expansion capability from the outset.
Long-Distance Heavy-Duty Travel
The bogie travels approximately 25 meters inside the kiln and an additional 25 meters outside, creating a total travel distance of nearly 50 meters.
Under heavy loads, rail alignment, fastening strength, and wheel guidance performance are critical to ensuring smooth movement and reducing wear on both wheels and rails.
Brick Kiln Rail System Solution
After evaluating the operating environment, load requirements, and future expansion plans, Glory Rail recommended a complete Brick Kiln Bogie Rail System specifically designed for heavy-duty industrial transportation applications.
The system included:
- 30kg rails
- Rigid rail clips
- Rail fishplates
- Chemical anchor bolts
- Custom cast steel rail wheels
- Machined steel axles
- Heavy-duty bearings
This integrated solution provided excellent performance in a high-temperature environment while ensuring sufficient capacity for future load increases.
Why Rigid Rail Clips Were Selected Instead of Elastic Fastening Systems
One of the most important engineering decisions in this project was the selection of the rail fastening system.
Many industrial rail systems use elastic clips combined with rubber rail pads to absorb vibration and reduce impact loads. However, for brick kiln applications, prolonged exposure to heat can accelerate rubber degradation and increase maintenance requirements.
To address this challenge, Glory Rail recommended a rigid fastening arrangement consisting of:
- Hard-mount rail clips
- Steel fishplates
- Chemical anchors
Benefits of the Rigid Rail Fastening System
- Excellent resistance to elevated temperatures
- No rubber components susceptible to thermal aging
- Consistent clamping force over time
- Reduced maintenance requirements
- Improved long-term stability for kiln operations
This solution was approved by the customer and successfully implemented on-site.
Custom Rail Wheel Design
In addition to the rail track components, the project required specially designed wheels for the bogie system.
Based on the customer’s engineering drawings, Glory Rail manufactured custom rail wheels optimized for the operating conditions of the kiln trolley system.
Wheel Specifications
| Item | Value |
|---|---|
| Tread Diameter | 381 mm |
| Flange Diameter | 419 mm |
| Flange Height | 19 mm |
| Total Width | 92 mm |
| Tread Width | 53 mm |
| Bore Diameter | 75 mm |
| Fillet Radius | R5 |
The R5 fillet radius helps reduce stress concentration between the wheel flange and rail side, contributing to longer wheel service life and smoother operation.
Axle Specifications
| Item | Value |
|---|---|
| Diameter | 75 mm |
| Length | 200 mm |
| Material | C45 Steel (45# Steel) |
Heavy-duty bearings were supplied together with the wheels and axles to ensure reliable performance under continuous industrial service.
Load Capacity Analysis
One of the key objectives of the project was to ensure that the industrial bogie rail system would remain suitable for future capacity upgrades.
Original Requirement
The customer’s initial target load was approximately 150 tons.
Future Requirement
The planned future operating load was approximately 400 tons.
Wheel Arrangement
The final system configuration included:
- 40 rail wheels
- 20 wheel assemblies
- Dual-rail track arrangement
Wheel Capacity Verification
Each custom wheel assembly was designed to support approximately 17–25 tons.
| Item | Value |
|---|---|
| Number of Wheels | 40 |
| Capacity per Wheel | 17–25 Tons |
| Total System Capacity | 680–1000 Tons |
| Future Design Load | 400 Tons |
Even using the lower load rating, the wheel system provides a total carrying capacity of approximately 680 tons, offering a significant safety margin above the customer’s future target load.
This design allows the customer to increase transportation capacity without requiring major modifications to the rail system.
