Double Girder Overhead Crane

Brand: Henan Hengkun Crane Co., Ltd.
Applications: Heavy-duty industrial environments including steel mills, shipyards, mining, automotive manufacturing, power plants, and large-scale logistics hubs.

Product Overview

Our double girder overhead crane is engineered for heavy-duty lifting operations, featuring robust construction, enhanced stability, and superior load-bearing capacity. Designed with European-inspired technology, it combines high efficiency, durability, and advanced safety systems to handle extreme workloads in demanding industries. Ideal for applications requiring precise control of heavy loads (up to 500 tonnes), this crane maximizes productivity while minimizing operational downtime.

Key Technical Advantages

Heavy-Duty Performance
- Reinforced double girder structure ensures exceptional rigidity and resistance to deformation.
- Optimized load distribution reduces stress on building infrastructure.
Advanced Safety & Control
- Intelligent PLC control system with anti-collision and anti-sway technology.
