Weihua European-style Double-beam Gantry Crane Exported to Mexico

Project Overview

In August 2025, a leading Mexican steel mill formally inquired about a high-performance gantry crane. The client specifically needed this equipment for the efficient lifting and stacking of steel structures.

In response, Weihua Group developed a customized solution tailored to these requirements. By early October, this project achieved a key milestone at the Weihua plant: a large gantry crane, with a lifting height of 30 meters and a span of 85 meters, successfully passed all operational tests and acceptance checks.

Once the crane is fully operational, it is expected to significantly enhance the client’s operational efficiency and material handling capacity.

Project Challenges

After understanding the client's site and work environment, we faced the following challenges:

• Strong Winds and Salt Spray Corrosion: Mexico's coastal areas are often subject to strong winds and high salt spray. The crane design needed to be wind-resistant to withstand the intense wind pressure. Heavy-duty corrosion protection, such as a specialized epoxy zinc-rich primer and salt-spray-resistant topcoat, was required for the metal structure and electrical components.
• High Altitude and Temperature Differences: The thin air at high altitudes may affect motor cooling efficiency. The large temperature swing between day and night places even higher demands on the toughness of the metal structure and weld quality. Motor power needed to be recalibrated, and wide-temperature electrical components were selected.
• Plant Layout and Space Constraints: The steel plant is densely populated with pipelines and intersecting operations, resulting in limited installation space. The hoisting route required precise planning to ensure a sufficient turning radius for the 85-meter main beam. Interference with existing infrastructure, such as blast furnace piping and power grids, must be avoided during installation.
• International Transportation of Oversized Structures: 30-meter-high, 85-meter-span structural components required custom seaworthy frame containers and lashing solutions.
• Customs Clearance and Standard Certification: Equipment and spare parts must have complete Mexican NOM certification documents. Coordinate with local customs clearance agents to ensure smooth customs clearance and avoid port detention risks.

Weihua Solution - European Double Girder Gantry Crane

Weihua Group developed this European double-girder gantry crane in strict accordance with European and American design standards. The crane fully meets customized requirements in structural grade, hoisting mechanism, and material selection. Furthermore, it achieves the highest operating level (A8), making it an intelligent solution for high-intensity, high-load environments. This design ensures superior structural performance and broad operational adaptability.

• Large-scale structure, comprehensive coverage of the operating area.

This gantry crane boasts a lifting height of 30 meters, a main beam length of 85 meters, and a span of 50 meters, enabling comprehensive coverage of a wide operating area and ensuring seamless material handling.

• Efficient operation system ensures continuous operation.

Equipped with a high-performance loading and unloading bridge trolley, it boasts a lifting speed of 50 m/min and an operating speed exceeding 150 m/min.

It flexibly maneuvers through large scrap yards, meeting the demands of high-intensity, continuous operations and improving work efficiency.

• Multifunctional spreaders, flexible for diverse scenarios.

Intelligent spreader placement allows for quick switching between various attachments, including electromagnetic chucks and hydraulic grabs. Whether lifting scrap steel or handling bulk materials, it easily handles and extracts materials, covering a full range of application scenarios.

• Dual anti-sway technology ensures precise and stable lifting.

The integrated mechanical and electrical closed-loop dual anti-sway system suppresses load sway in a fraction of a second, even at high speeds, ensuring fast, accurate, and stable positioning and handling. Comprehensive Safety Protection System

The hoisting mechanism is equipped with a real-time height monitoring system. Key components such as the hoisting motor, brake, and wire rope are equipped with ample safety margins. A pin-type overload sensor boasts a five-fold overload capacity, sensitively detecting unbalanced loads and ensuring safe operation.

• Highly reliable design adapts to extreme operating conditions.

To meet the steel mill's 24 operation requirements, the equipment's core components (such as the hoisting and operating mechanisms) feature an ultra-long life design, extending the overall service life. Furthermore, the system integrates an internationally advanced communications solution to ensure continuous and stable power supply and signal transmission.

Customer Feedback

Weihua Group recently received a thank-you email from a Mexican customer. The customer reported that their European-style double-girder gantry crane has performed exceptionally well since starting operation. They confirmed the equipment maintains stability and reliability during high-intensity operations in demanding environments.

The customer specifically highlighted the crane's anti-sway performance and fast spreader switching capability. These features have significantly improved their scrap handling efficiency. The equipment fully meets their requirements for 24-hour continuous operation. The customer concluded by expressing their expectation to cooperate with Weihua Group again in the future.

Project Achievements

The successful delivery of this high-end intelligent loading and unloading gantry crane is a powerful testament to Weihua's technological innovation capabilities and international manufacturing capabilities, and marks a further advancement of "Made in China" in the international high-end market. Its commissioning will significantly improve the efficiency, safety, and intelligence of the Mexican partner steel mill.

Currently, two subsequent gantry cranes of the same model are in full production. In the future, the three units will operate in tandem, providing the steel mill with continuous, stable, and intelligent material handling capabilities, further strengthening its regional industrial competitiveness.
