The capacity upgrade project at the steel plant presented major challenges in terms of heavy load, extreme temperature, and safety requirements. TXLET delivered a 300T metallurgical overhead crane with an optimized design, ensuring stable, efficient, and reliable operation. The successful implementation not only enhanced the customer’s production efficiency but also reinforced TXLET’s reputation in the global steel industry.
In a major metallurgical line upgrade project at a leading, high-capacity steel conglomerate, the client set exceptionally high and stringent requirements for the lifting equipment. Their entire core production process – from receiving and transporting molten iron at the blast furnace, moving molten steel to the converter, to the precise pouring and handling of ingots – demanded the support of an ultra-heavy-duty overhead crane.
This is an Ultra-severe Operating Environment where temperatures exceeding 1000°C, loads in excess of 300 tons, and continuous 24/7 operation are inseparable elements. The client required a crane solution that was not only mechanically robust but also guaranteed absolute safety in accordance with international standards, delivered uninterrupted operational stability, and optimized the limited installation space within the steel mill.
Against this backdrop, TXLET – a global leader in industrial lifting solutions – was selected as the trusted partner to provide the 300T Foundry Overhead Crane solution. This equipment was custom-engineered to meet the most demanding standards of the modern steel industry and ensure strategic reliability in the global supply chain.
The project posed a series of complex technical and operational challenges, requiring a breakthrough solution:
Each heat can involve hundreds of tons of molten iron or steel. This necessitated a crane with the capacity for sustained, absolutely stable load bearing and micrometric precision during every lift and pour, preventing any sway or misalignment that could lead to a catastrophic molten metal leak incident.
The furnace area consistently maintains temperatures in the thousands of degrees Celsius. This extreme heat creates enormous thermal stress and deformation pressure on the main and secondary mechanical structures, electrical systems, and sensors. The equipment needed thermal deformation resistance, material fatigue resistance, and sustained performance over long periods.
Even a minor error during the lifting of hot metal could lead to serious accidents. Therefore, the requirement for Redundancy Design and European-level safety standards (FEM) was paramount, maximizing the protection of human life and assets.
The metallurgical cycle is uninterrupted. This means that the crane must operate steadily and without interruption, even during crises or regular short-term preventative maintenance.
The plant aimed to maximize floor space. The crane required a compact design with optimized lifting height while still ensuring robust operation and structural durability with a 300-ton load capacity.
Beyond the initial investment, the client was particularly concerned with reducing routine maintenance costs, increasing component lifespan, and ensuring easy, quick replacement of critical parts.
These challenges demanded a crane solution that was not only technically compliant but also strategically and economically viable in the long term, enabling the client to ensure absolute safety, optimize productivity, and achieve superior cost efficiency compared to competitors.
Following an in-depth on-site survey and detailed analysis of the client's needs, TXLET delivered a comprehensive and exclusive solution: the 300T Foundry Overhead Crane, specifically designed for high-intensity steel production environments, achieving FEM Working Classification T8. This solution converges precision mechanical power, triple-layer safety assurance, advanced electrical control technology, and long-term sustainability.
This is the mandatory specialized configuration for super-heavy cranes, ensuring even load distribution, reducing stress concentration, and maximizing absolute stability when lifting massive molten metal loads, significantly mitigating sway during pouring.
All load-bearing girders and frames are fabricated from high-grade alloy steel and undergo a complex thermal treatment process to eliminate residual stress and prevent physical deformation during prolonged high-temperature operation.
All critical load-bearing welds are 100% inspected using industrial Ultrasonic Testing, combined with precision CNC machining to guarantee the concentricity and parallelism of the rails and drives. This ensures smooth crane operation, minimizes friction, reduces vibration, and suppresses noise.
This is a key innovation. Instead of replacing the entire pricey hook assembly when worn, the client only needs to replace the protective liner made of a special wear-resistant material. This solution doubles the hook’s lifespan, significantly reduces maintenance costs, and minimizes Downtime.
Selection of special heat-resistant materials capable of withstanding high-temperature environments and large dynamic loads, ensuring sustained performance without overheating.
The entire metal surface is treated with multiple coats of industrial-grade paint, providing resistance against oxidation and corrosion caused by hot vapor and chemical dust in the steel mill.
A main transformer supplies power to the entire system, while a secondary (auxiliary) transformer is ready to activate instantly upon power failure. This guarantees the crane never loses power mid-lift while handling molten metal—a mandatory safety requirement.
All wiring utilizes Foundry-grade Cables, offering high heat resistance and, critically, Flame Retardancy.
TXLET utilizes advanced Variable Frequency Drive (VFD) control technology, which optimizes motor power output, substantially reduces power consumption during variable loads, and minimizes shock during start/stop.
Two separate hoist units can completely substitute the function of the other in case of a component failure. Two gearboxes, two motors, two braking systems, and two cable systems operate in parallel to ensure 100% lifting capacity remains available.
A central Programmable Logic Controller (PLC) automatically monitors and switches between mechanisms, allowing the crane to maintain continuous operation without manual intervention.
The system undergoes fault simulation testing and a 150% static overload test before handover, guaranteeing real-world operational capability in a 24/7 environment with the highest safety level.
Includes high-power LED lights, loud audible alarms, and visual signals on the HMI control screen, providing immediate alerts upon detecting risks such as overload, overheating, or overspeed.
IoT sensors are installed at critical points (hooks, ropes, bearings) to measure load, temperature, vibration, and wear levels. All data is transmitted to the control center for analysis and issuing timely predictive maintenance alerts.
Absolutely prevents free fall, collisions, and over-travel limits, ensuring safety for both workers and the metallurgical line.
TXLET designed the crane to achieve maximum lifting height and minimum hook approach to the support columns, fitting within the confined space of the steel mill, especially for short crane spans.
Equipped with anti-vibration operator seats, an industrial air conditioning system, heat-resistant camera monitoring, and intuitive display screens, enhancing safety and convenience for the operator in the hot environment.
With this superior and comprehensive technical solution, TXLET not only meets the client's stringent requirements but also provides absolute peace of mind regarding safety, long-term sustainability, and outstanding economic efficiency.
