Why Choose The Dongqi 50-Ton Double Girder Gantry Crane?

At Dongqi, we understand that investing in a crane is a major decision. Our products are built not just to meet standards but to exceed your expectations for performance, durability, and value.

1. Exceptional Lifting Capacity & Structural Integrity
With a robust 50-ton lifting capacity, our MG model handles your most demanding tasks with ease. The crane features a double girder design constructed from high-strength Q355B steel alloy. This design provides superior structural rigidity and resistance to deflection and deformation, even when operating at full capacity, ensuring consistent performance and longevity.

2. Uncompromising Safety and Operational Stability
Safety is our highest priority. Every Dongqi crane integrates multiple layers of protection:

  • Advanced Safety Systems: Standard equipment includes an overload limiter, emergency stop buttons, travel limit switches for all motions, and anti-collision systems.
  • Premium Components: We use top-tier Chinese motors, gearboxes, and brakes, with options for international brands like Siemens, Schneider, or ABB for ultimate control and reliability.
  • Rigorous Compliance: Our cranes are designed and manufactured in full compliance with international standards (GB/T, FEM), guaranteeing a safe working environment for your personnel and assets.

3. Fully Customizable Design for Your Unique Needs
We know that no two worksites are identical. That’s why the Dongqi DQ MG crane is highly customizable to fit your specific application:

  • Span & Lifting Height: We will tailor the span (typically from 18m to 35m+) and lifting height to your facility’s exact dimensions.
  • Work Duty: Available in work classes from A5 to A7, we match the crane’s duty cycle to your operational intensity, ensuring optimal performance without over-specification.
  • Intelligent Options: Enhance control and precision with Variable Frequency Drive (VFD) for all motions, ensuring smooth acceleration and deceleration and pinpoint load positioning. Choose from cabin, pendant, or wireless radio remote control.

4. Engineered for Durability and Low Lifetime Cost
Built for tough environments, our cranes undergo a comprehensive anti-corrosion process, including shot blasting and multiple coats of high-quality paint, making them suitable for both indoor workshops and outdoor yards. The modular design simplifies maintenance and reduces downtime, significantly lowering your total cost of ownership.
