360t Casting Crane Commissioned: Powering Stable High-Capacity Steel Production

Project Background

Saicomech recently supplied a 360-ton casting crane for a steel plant in Luzhou, Sichuan, China. After commissioning and actual operation, the crane ran smoothly, safely, and with high positioning accuracy, earning strong praise from the customer. The project supports a steel production capacity of 2 million tons and represents one of the larger casting crane applications in the domestic market.

This case is a strong example of how large-tonnage lifting equipment can directly support the core production needs of heavy industry. In steelmaking and casting environments, cranes must do more than lift molten metal-related loads -- they must operate with high reliability, precise control, and strong safety assurance under demanding industrial conditions.

Customer Needs and Application Scenario

The customer needed a casting crane capable of meeting the requirements of a large-scale steel production line with 2 million tons of annual capacity. In such a scenario, the crane is not a support device in the background; it is a critical production asset that affects furnace-side handling, process continuity, and overall plant safety.

For this type of operation, the main concerns are clear:

• high lifting capacity,
• stable and accurate movement,
• reliable redundant design,
• and strong fault protection for continuous industrial use.

Because casting crane operations are closely tied to high-temperature, heavy-load, and high-risk production environments, the customer required a solution that could deliver both performance and safety without compromise.

Our Solution and Product Features

Saicomech provided a 360-ton casting crane built with large-tonnage engineering and precision manufacturing. Key features included:

• Overall machining of the bridge structure and trolley frame using large-scale processing equipment, improving assembly accuracy and operating performance
• Fully digital thyristor stator voltage regulation and frequency conversion control, offering precise operation and better speed regulation
• Fault self-diagnosis functions, helping operators identify and respond to issues more quickly
• Precision positioning capability, improving operational control and handling accuracy
• Redundant design across major mechanisms, enhancing operational reliability
• Safety monitoring system, supporting safe and stable crane operation

This combination of design and control features was intended to ensure not only that the crane could handle large loads, but also that it could do so consistently, accurately, and safely in a critical steel production environment.

Implementation and Key Milestones

After delivery and installation, the 360-ton casting crane was put into actual production use. Once in operation, the equipment demonstrated stable running performance, strong safety behavior, and accurate control.

The plant manager, Mr. Wang Junli of Luzhou Xinyang Vanadium Titanium Steel, commented that the crane's technology was solid and its performance fully met the needs of the plant's 2 million-ton steel capacity. This on-site feedback confirms that the equipment was not only delivered successfully, but also validated under real production conditions.

Final Results and Value

This project delivered several important outcomes:

1. Stable operation under heavy-duty casting conditions
2. High safety and reliability through redundant system design and monitoring
3. Precise control and positioning, supporting demanding industrial tasks
4. Improved production assurance for a large steel capacity operation
5. Customer confidence, strengthened by successful real-world performance

For the customer, this means the crane can be trusted as a key part of the production system. For Saicomech, it further proves our capability in large-tonnage casting crane manufacturing and our strength in serving high-value heavy industrial projects.
