A large steel coil manufacturing company from Bangladesh recently expanded its production line and needed to purchase bridge cranes for the new production line. Mr. Shariful contacted us through our website to inquire about a quote for the 10-ton bridge crane. They had a large order volume on their production line, so they needed a reliable bridge crane to help them transport steel coils. After communication with the customer, the customer mentioned the problems they had encountered in their factory during the communication process and clearly stated that the solution we provided should avoid these problems.
Operational Challenges with Existing Equipment
Before upgrading their crane system, the steel plant faced several operational difficulties that affected production efficiency and safety.
| Challenge Categories | Specific manifestations |
|---|---|
| Frequent Equipment Breakdowns | Worn brakes, overheated motors, malfunctioning limit switches |
| Poor control accuracy | Direct start, start-stop shock is big, the steel coil in the air shaking serious |
| Excessive energy consumption | Old motors without inverter control, starting current is 5-7 times of rated current |
| Severe space constraints | The roof of the cold rolling shop is low, and the clear height under the rails is sometimes slightly insufficient |
1. Insufficient Lifting Capacity
The existing overhead cranes in the workshop were rated for less than 10 tons, which was insufficient for handling full steel coil bundles. Operators had to divide heavy loads into smaller batches before lifting. This process significantly increased handling time and doubled the number of lifting cycles, slowing down the production workflow.
2. Frequent Breakdowns and Maintenance Issues
Due to continuous heavy use, the aging crane equipment experienced frequent mechanical failures. Bearings, brakes, and hoist motors were subject to excessive wear. Unexpected breakdowns often forced the production line to stop for several hours, disrupting the plant's operating schedule.
3. Poor Speed Control and High Energy Consumption
The existing cranes used traditional direct-start electrical systems. Each start generated a high inrush current, increasing power consumption and operational costs. In addition, the lack of speed regulation caused sudden starts and stops, resulting in load swing and increased mechanical stress on crane components.
4. Limited Indoor Space
The cold rolling workshop had relatively low ceilings and narrow production aisles. Large conventional crane structures would reduce available headroom and interfere with existing machinery. The customer required a compact crane design capable of delivering full lifting capacity without occupying excessive space.
5. Continuous 24/7 Operation Requirement
Steel coil production requires almost uninterrupted operation. The crane system needed to support long working hours and high-frequency lifting cycles, making reliability and durability critical design considerations.

To design a more accurate steel slab handling crane solution, we requested workshop drawings from the Bangladesh client. According to the client's requirements and the factory conditions, Yuantai Crane designed 1 set of 10 ton double girder overhead crane(European-style) for the Bangladesh steel plant, as we discovered that the client's workshop is relatively small and has limited space, so the European-style low headroom crane is better suited to the client's requirements. Our recommendation and design solution were well received by the client.
Advantages of Yuantai European Overhead Crane
Yuantai's European overhead crane solution delivers clear, practical benefits for anyone looking to buy an industrial crane. It follows European (FEM) design ideas to give a predictable, safe, and well-engineered product. The design focuses on reliability, easy maintenance, and efficient operation. That makes the crane a solid choice whether you need steady daily use or occasional heavy lifts.
1. Smooth and Precise Operation with Frequency Converter
Equipped with frequency converter which could adjust its speed in order to make the bridge crane traveling more smoothly and steady. The built-in frequency converter lets you control travel speed precisely. Smooth starts and stops reduce load swing and protect the structure. You get finer positioning and gentler handling of loads. That improves safety and extends the life of mechanical parts.
2. Meets Client Requirements and Enhances Work Efficiency
The 10 ton overhead crane fully meets client's requirements and improves their working efficiency. A 10-ton capacity fits many medium-heavy industrial tasks. When sized correctly, the crane speeds up material flow and cuts the number of lifts needed. Yuantai can match features—such as controls and safety devices—to your workflow so the crane actually helps you work faster and safer.
3. Reduced Maintenance Requirements and Lower Operating Costs
Less maintenance also saves much time and cost which satisfied client. The crane is built with durable parts and easy access for inspection. That lowers routine service time and reduces unplanned downtime. Fewer repairs mean lower labor and spare-part expenses. In practice, you spend less time on upkeep and more time running the job.
4. Competitive and Cost-Effective Pricing
We offer bridge cranes at very reasonable prices as well. Our cranes utilize high quality parts and proven designs. Considering the initial purchase price, energy consumption, and maintenance requirements, you'll find that our custom cranes are extremely advantageous in the long term.
What the Bangladesh Client Say
The 10 ton EOT crane is running well in Bangladesh steel coil plant. According to the feedback of MD Shariful, our material handling equipment, such as, EOT crane, bridge crane, has a huge market in Bangladesh. At the end of this year they have the plan to purchase a 5 ton bridge crane and 10 ton bridge crane from us again, to meet their further expanded production needs. What a pleasant cooperation!
