Zhongtian Iron & Steel Group has implemented our MG25t double girder electromagnetic 갠트리 기중기 to achieve intelligent upgrades in scrap steel handling. Featuring core technologies such as electromagnetic lifting, laser positioning, and an intelligent monitoring platform, the crane significantly enhances operational efficiency and safety, providing the steel metallurgical industry with an “efficient, safe, and green” logistics solution. This project advances gantry crane development toward specialization and intelligence, helping enterprises reduce costs and increase productivity.

Zhongtian Iron & Steel Group Co., Ltd. Overview

Zhongtian Iron & Steel Group Co., Ltd., headquartered in Changzhou, Jiangsu Province, China, was founded in September 2001 and has grown into a major diversified steel conglomerate with annual revenue near RMB 200 billion. The company integrates ironmaking, steelmaking, steel deep‑processing, and modern logistics, while also operating in agriculture, education, real estate, and commerce. Recognized with multiple national and provincial honors, Zhongtian produces a wide range of high‑quality steel products for domestic and export markets, exemplifying a modern, vertically integrated, and innovative steel enterprise.

Electromagnetic Gantry Crane Equipment Overview

To improve scrap steel handling efficiency, Zhongtian Steel introduced the MG25t double girder electromagnetic gantry crane. The electromagnetic gantry crane features a double girder truss structure with a 36 m span and 20 m lifting height. It is equipped with an electromagnetic disk (2.5 m diameter, 15 t lifting capacity) and supports both ground remote control and cabin operation modes. The crane complies with GB/T 3811 crane design standards, holds ISO 12482 safety certification, and is specially adapted for high-temperature, dusty steelmaking environments.

Core Application Scenarios

Scrap Steel Transfer Across Bays

• Task: Lift fragmented scrap steel (18 t per bucket) to the steelmaking furnace
• Outcome: Electromagnetic grab system (response ≤3 s) combined with intelligent trolley obstacle avoidance increased transfer efficiency by 50% and reduced manual intervention by 80%.

Billet Yard Management

• Task: Multi-layer billet stacking and retrieval (3 t per billet)
• Outcome: Laser positioning system (accuracy ±10 mm) ensured precise billet placement, improving yard utilization by 40%.

Maintenance Assistance

• Task: Lift rollers and bearing housings (12 t per piece)
• Outcome: Variable-frequency drive system (lifting speed 0.5–10 m/min) with hydraulic anti-sway improved maintenance safety by 75%.

Electromagnetic Gantry Crane Technical Innovations

Electromagnetic–Mechanical Dual Drive System

• Electromagnetic disk features redundant power supply and UPS backup, maintaining lift for 15 min during power failure.
• Optional mechanical grab mode adapts to mixed scrap sorting needs.

Intelligent Monitoring and Early Warning

• Integrated stress, temperature, and anti-collision monitoring systems.
• Supports remote monitoring platform with real-time key parameter transmission to the dispatch center.

Structural Safety Enhancements

• Main girder built from Q345D high-strength steel with local reinforcement to Q460E.
• Equipped with wind-anchoring system (wind resistance level 12).

User Feedback and Benefits

• Efficiency: Scrap steel handling increased from 800 t/day to 1,200 t/day; steelmaking cycle reduced by 2 hours.
• Cost Optimization: Electromagnetic disk consumes 40% less power than traditional mechanical grabs, saving ~RMB 800,000 annually.
• Safety Record: Zero safety incidents in three years of operation; ISO 45001 occupational health and safety certified.
