500t Double-Trolley Overhead Crane for Offshore Wind Project
Heavy 500t-class Henan Mine Crane bridge crane installed for offshore wind component manufacturing.
World-scale offshore wind manufacturing requires cranes capable of moving extremely large components through assembly, turning and installation processes. A 500t-class crane must provide capacity, hook coordination and precise low-speed control while fitting the heavy workshop structure.
Henan Mine Crane supplied a 500t double-trolley new-type double-girder crane for an offshore wind project. The original project report states that 43 crane sets were supplied for Phase I, and highlights lightweight hoisting design, high lifting height, automatic fast/slow speed adjustment, multi-hook synchronization, electrical anti-sway and digital/video monitoring.
Project Background
Offshore wind components continue to increase in size, which raises both crane capacity and load-control requirements. Large nacelles, generator assemblies and production fixtures may need more than one trolley or hook to distribute load and control orientation.
For procurement, the crane should be reviewed together with the building design because runway loads, span, hook approach, headroom, lifting height and maintenance access influence both crane and workshop engineering.
Customer Challenges
- 500t-class heavy lifting for very large wind-power components.
- Coordinating two trolleys or multiple hooks during balanced lifting.
- Providing high lifting height without excessive mechanism weight.
- Switching between efficient travel speeds and precision assembly speeds.
- Reducing load sway during movement of high-value components.
- Managing a large Phase-I crane fleet with consistent monitoring and maintenance standards.
Henan Mine Crane Solution
The referenced 500t crane uses a double-trolley, double-girder configuration for heavy wind-power handling. Lightweight hoisting design supports high lifting height and reduces unnecessary energy consumption in the heavy workshop.
Automatic fast/slow speed adjustment matches production travel and precision positioning. High-precision multi-hook synchronization supports balanced lifting, while electrical anti-sway improves load stability.
Digital and video monitoring plus lifecycle management provide additional operational visibility across the project crane fleet.

- Large project crane schedules can be standardized for controls and maintenance while capacities remain application-specific.
Frequently Asked Questions
Why use a double-trolley crane for offshore wind manufacturing?
Two trolleys provide additional flexibility for distributed lifting, load orientation and handling of very large components with multiple lifting points.
Does every offshore wind project need a 500t crane?
No. 500t is the referenced project capacity. The correct capacity depends on the heaviest component, rigging, lifting beam, assembly sequence and future product range.
What should be included in the RFQ for a 500t wind-power crane?
Provide component drawings and weights, lifting points, trolley operating modes, span, lifting height, hook approach, runway data, duty cycle, speeds and required synchronization accuracy.
