600t Pumped Storage Power Station Overhead Crane Solution
Large synchronized overhead crane installed in an underground pumped-storage powerhouse.
Pumped-storage power stations need very high-capacity cranes to install and maintain generator-motor units, turbine components and other heavy equipment inside restricted powerhouse spaces. Procurement decisions are driven by capacity, hook arrangement, lifting height, headroom, synchronization accuracy and long-term maintenance access.
Henan Mine Crane supplied multiple crane types for a national pumped-storage project, including a 600t bridge crane. The referenced 600t crane uses a new low-headroom structure, variable-frequency control, high-precision dual-hook synchronization, intelligent anti-sway and digital monitoring.
Project Background
Underground or cavern powerhouses impose strict dimensional limits on crane geometry. A large crane must maximize usable lifting height while fitting the building envelope and maintaining access for installation and maintenance.
Heavy hydro-generator components may also require two hooks or multiple lifting points. Synchronization between lifting mechanisms is therefore a central technical requirement, especially when the load has limited allowable tilt.
Customer Challenges
- Very high lifting capacity for turbine-generator installation and overhaul.
- Restricted powerhouse headroom and limited crane-envelope clearance.
- High-precision synchronization between two main lifting points.
- Reducing load sway while positioning large, high-value power-generation components.
- Providing operating and condition visibility for a production-critical crane.
- Coordinating factory pre-assembly, site installation and lifecycle quality management.
Henan Mine Crane Solution
The referenced 600t bridge crane uses a low-headroom structural arrangement to improve space utilization in the pumped-storage powerhouse.
Variable-frequency control provides smooth speed regulation, while high-precision dual-hook synchronization supports balanced lifting of large components. Intelligent anti-sway reduces oscillation during travel and positioning.
Digital monitoring provides operating information for equipment management. The original project also emphasizes factory pre-assembly before delivery and lifecycle quality follow-up after installation.

Why Choose Henan Mine Crane
- Henan Mine Crane can engineer capacity, hook arrangement and low-headroom geometry from the actual powerhouse layout.
- Multi-hook synchronization and anti-sway can be configured around the allowable load tilt and positioning requirement.
- Factory pre-assembly can be planned to reduce site interface risk for very large cranes.
- Lifecycle monitoring and maintenance access can be considered during the initial design rather than added later.
Frequently Asked Questions
How is a pumped-storage powerhouse crane capacity selected?
Capacity must include the heaviest generator or turbine component plus lifting beam, hook block, rigging and any required design margin under the governing standard.
Why is dual-hook synchronization important?
Large components may be lifted from two points. Synchronized hoisting reduces differential movement and helps control load tilt.
What drawings should be provided for a 600t-class crane RFQ?
Provide powerhouse cross-sections, runway level, span, lifting height, pit or equipment coordinates, maximum load drawings, lifting points, installation sequence and maintenance requirements.
