Project Overview
In 2023, Glory Track supplied a complete kiln bogie system for a kiln transportation project in Nigeria.
The client is a heavy industrial manufacturer serving the oil & gas and energy sectors, with core capabilities in pressure vessel fabrication, process packages, subsea structural steel, storage tanks, and offshore steel structures. The company provides integrated services including engineering design, procurement, fabrication, and site installation.
The project required a reliable kiln rail system to support heavy-duty material transfer inside a brick production line. The system had to operate under high-temperature influence, heavy load conditions, and future capacity expansion requirements.
The complete system was manufactured and shipped in July 2023 from Tianjin Port to Onne Port, Nigeria.
Project Requirements & Engineering Challenges
High-Temperature Operating Condition
The kiln area is continuously exposed to thermal radiation, with furnace temperatures reaching up to 650°C.
Although the bogie system does not operate directly inside the flame zone, the rail structure is still affected by long-term heat exposure.
Under such conditions, rubber-based rail fastening systems are not suitable. Prolonged exposure to high temperatures can cause rubber pads to age, lose elasticity, and reduce clamping force, which may lead to rail loosening and reduced operational safety.
To ensure long-term reliability, a rigid rail fastening system was selected for this kiln rail system project.
Heavy Load and Future Expansion Requirement
The initial design load was approximately 150 tons, including the bogie structure, kiln body, bricks, and production materials.
During the engineering phase, the client requested future scalability, with a potential increase to around 400 tons of operating capacity.
Therefore, both the kiln bogie system and wheel assemblies were designed with sufficient structural redundancy from the beginning to avoid future reconstruction.
Long-Distance Rail Operation
The total rail length is approximately 50 meters:
- 25 meters inside the kiln area
- 25 meters outside the kiln zone
The bogie system operates continuously between indoor and outdoor sections, requiring stable rail alignment and reliable performance of the bogie rail system under repeated cycles.
System Solution by Glory Track
The solution was designed as a three-layer heavy duty rail system:
- Kiln rail system
- Rail fastening system
- Bogie wheel and axle system
Kiln Rail System
The main running track uses 30kg/m steel rails for stable bogie operation.
Supply scope:
- 30kg rails: 40 pcs × 4 m
- 30kg rails: 8 pcs × 4.75 m
This rail profile is widely used in brick plants, foundries, and industrial transport systems due to its balance of strength, durability, and cost efficiency.
Rail Fastening System
To meet high-temperature working conditions, a rigid fastening solution was adopted instead of conventional elastic fastening systems.
Supply scope:
- Rigid rail clips: 620 sets
- Fishplates: 48 sets
- Chemical anchor bolts M12 × 160 mm: 460 sets
This system eliminates the risk of rubber degradation in high-temperature environments and ensures stable long-term performance of the kiln rail system.
Customized Bogie Wheel System
Based on the client’s engineering drawings, Glory Track manufactured a complete set of customized bogie wheel assemblies.
Wheel Specifications
- 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
Quantity:
- Wheels: 40 pcs
The flange geometry ensures stable guidance along the rail, while the R5 fillet design reduces stress concentration and improves fatigue resistance.
Axle System
- Diameter: 75 mm
- Length: 200 mm
- Material: #45 steel
Quantity:
- Axles: 40 pcs
#45 steel provides excellent strength and toughness for heavy-duty bogie rail system applications.
Bearing System
- Bearings: 40 sets
All wheel assemblies were pre-assembled and inspected before shipment to ensure smooth on-site installation.
Load Capacity Design
Although the initial requirement was 150 tons, the system was designed with future expansion up to 400 tons in mind.
Each wheel unit has a conservative load capacity of approximately 17–25 tons.
With 40 wheel sets, the theoretical total capacity exceeds 540 tons, providing sufficient safety margin for future heavy-duty operation upgrades.
Manufacturing & Quality Control
All components were manufactured strictly according to approved technical drawings.
Quality control included:
- Dimensional inspection
- Assembly fit verification
- Structural consistency checks
- Final pre-shipment inspection
All components were packaged in system-based modules to improve installation efficiency on site.
Shipment & Delivery
The project was shipped in July 2023 from Tianjin Port, China to Onne Port, Nigeria.
Delivery was organized in modular systems:
- Kiln rail system components
- Rail fastening system components
- Bogie wheel system components
During packaging:
- Wheels and bearings were individually protected to prevent impact and rotation damage during sea transport
- Steel rails were bundled and reinforced with steel straps for structural stability
- All components were labeled according to installation sequence to support on-site assembly
This modular delivery approach ensured efficient installation and reduced on-site handling complexity.
Project Outcome
This project delivered a complete kiln bogie system, providing a reliable solution for heavy-duty brick production operations.
Key benefits include:
- Stable performance in high-temperature environments
- Reliable operation under heavy load conditions
- Scalable design supporting future capacity expansion
- Customized bogie wheel and axle system
- Reduced long-term maintenance requirements
- Improved system lifecycle efficiency
This project demonstrates Glory Track’s capability in delivering engineered kiln rail systems and heavy-duty bogie rail system solutions for demanding industrial applications.
