Project Background

Industry Context in Nigeria

The client is based in Nigeria and operates within the oil and gas processing sector. Their workshop handles heavy equipment, valves, and steel components that require frequent lifting and positioning during production and maintenance. In this type of environment, safety is always a priority, especially when flammable gases and vapors may be present. Any spark from a crane system could lead to serious consequences, which is why standard lifting equipment is not suitable.

Operational Challenges

The client faced several day-to-day challenges in their workshop that made their existing lifting setup inefficient:

• Hazardous environment: The presence of explosive gases required equipment that could fully meet explosion-proof standards.
• Heavy lifting demand: Regular handling of components weighing up to 15 tons needed a stable and durable crane system.
• Limited space: The workshop was designed with restricted headroom, so the crane had to fit into the available structure without sacrificing lifting height.
• Continuous operations: With multiple shifts running daily, downtime caused by unreliable lifting equipment was not acceptable.

Why They Needed an Explosion-Proof Overhead Crane

Given these challenges, the client required a crane solution that could provide both safety and efficiency. A conventional overhead crane would not meet the explosion-proof requirements, and using mobile lifting equipment was neither safe nor practical for their workshop layout.

The main reasons they decided on an explosion-proof overhead crane were:

• Compliance with safety regulations in hazardous zones.
• Higher reliability compared to traditional lifting methods.
• Optimized space usage through a low headroom design that allowed maximum hook height in the limited building clearance.
• Ability to handle critical lifts of 15-ton components with precision and stability.

This background set the stage for finding a customized explosion-proof overhead crane solution that could be safely installed and operated in Nigeria’s demanding industrial environment.

Client Requirements

When the client first approached us, they had very clear expectations for the type of lifting system they needed. Their operations involved handling heavy loads inside a hazardous environment, which meant the crane had to do more than just lift and move materials. It had to guarantee safety, match the building dimensions, and comply with international explosion-proof standards. At the same time, the solution needed to be practical enough for daily use and long-term reliable operation.

The specific requirements provided by the client included:

• Safe lifting solution suitable for hazardous working environments.
• Lifting capacity of 15 tons to cover their heaviest equipment.
• Crane span: 13 m, designed to fit the workshop’s layout.
• Lifting height: 8.95 m, ensuring enough clearance for loading, unloading, and maintenance work.
• Power supply: 400V, 50Hz, 3 Phase, matching Nigeria’s local industrial standard.
• Two units of cranes, allowing parallel operations in the same facility.
• Complete system with runway beams included, avoiding the need for separate fabrication on site.
• Explosion-proof standard: Ex II 2 G Ex de IIC T4, making the cranes safe for use in gas-risk areas.

By defining these requirements clearly from the start, the client ensured that the final solution would not only meet their lifting needs but also address critical safety concerns. This helped us design and propose a system that was both technically sound and ready for seamless integration into their workshop.

Our Solution

After listening carefully to what the client needed, we came up with a complete package that could tick all the boxes—safe, reliable, and easy to fit into their workshop. Instead of just supplying cranes, we made sure the system, including the runway beams, was tailored to their site and ready for smooth installation.
 

Crane Design

We recommended a European-style double girder overhead crane because of its solid build and precise handling.

• Its compact frame made the best use of the available space.
• A low headroom hoist with crab trolley was selected to give the client maximum lifting height without needing to change their building structure.

Explosion-Proof Configuration

Since the workshop involved explosive gases, safety had to come first.

• Every electrical and mechanical part was designed to meet the strict Ex II 2 G Ex de IIC T4 standard.
• This setup allowed the cranes to run safely in both gas and dust environments, giving the client peace of mind.

Runway System

The project also included the full runway beam system, built to match the client’s layout.

• The design provided a stable track for crane movement, ensuring smooth operation across the span.
• By supplying the ready-to-install beams, we helped the client cut down on local fabrication and speed up the installation process.

Quality Assurance

To make sure everything met expectations, we followed strict quality checks before shipping.

• All cranes were built under CE and ISO-certified standards.
• A third-party inspection was carried out so the client could be confident the cranes would perform as promised once they arrived in Nigeria.

In the end, the solution was not just about delivering cranes—it was about providing a system the client could rely on for safe and efficient operation in a tough working environment.

Project Execution

Delivering overhead cranes of this size and type to an overseas client requires careful coordination at every stage. From the very first technical drawings to the final commissioning, we worked closely with the client to make sure the process stayed clear and on schedule.

We began by preparing detailed engineering drawings based on the client’s workshop layout. These drawings were reviewed together and approved, ensuring that every measurement, span, and specification matched the actual site conditions.

Once the design was confirmed, the cranes moved into fabrication and factory testing. Each unit went through load testing and functional checks in our facility, allowing us to make fine adjustments before shipment. This step gave the client assurance that the cranes would work as intended once installed.

After testing, the cranes and runway beams were securely packed for export. Special attention was given to protective measures during packing, since the equipment had to withstand a long sea voyage before reaching Nigeria.

The final step was installation and commissioning support. Our engineers provided remote guidance, walking the client’s local team through the setup process. This ensured the cranes were installed properly, aligned with the runway beams, and safely put into service.

By following this step-by-step approach, the project was delivered on time and without unnecessary delays. The client could begin using their new cranes with confidence, knowing that the equipment was correctly installed and ready for reliable daily operation.

Results & Client Benefits

After installation and commissioning, the client immediately noticed several practical benefits from their new overhead cranes. The system was designed to meet the real demands of a hazardous workshop, and it delivered exactly what was promised:

• Safe and reliable material handling: The explosion-proof design allowed the client to move heavy equipment and components without any risk of sparks or accidents.
• Space-saving layout: The low headroom hoist and compact crane design maximized available lifting height and made efficient use of the workshop space.
• Reduced downtime: High-quality components and explosion-proof protection meant fewer maintenance interruptions and safer, continuous operation.
• Smooth operation: Both cranes worked seamlessly along the runway system, providing consistent performance for parallel lifting tasks.
• Client satisfaction and long-term cooperation potential: The client was pleased with the professionalism, on-time delivery, and tailored design, setting the stage for future projects together.

This combination of safety, efficiency, and reliability helped the client improve their operations immediately while giving them confidence in the longevity of the equipment.

Conclusion

This project successfully delivered two sets of 15-ton, 13-meter span, explosion-proof overhead cranes complete with runway system, customized to fit the client’s workshop and operational needs.

The case highlights the practical value of choosing a well-designed, explosion-proof crane system for industries in Nigeria, including oil and gas, petrochemical plants, and mining operations.
