Gantry crane
Single Girder Gantry Crane
Product Overview
The 25-Ton Electric Hoist Single Girder Gantry Crane is an innovative and powerful lifting solution that combines the high capacity typically found in double girder systems with the cost-effectiveness of a single girder design. This crane is engineered for heavy-duty performance, featuring a robust main girder and A-frame legs with motorized travel on ground-level rails or heavy-duty tires. Paired with a high-performance 25-ton electric hoist, it provides exceptional lifting power without requiring an overhead building runway, making it a versatile choice for outdoor yards and large indoor workshops.
Product Advantages
- High Capacity, Single Girder Design: Delivers an impressive 25-ton lifting capacity in an economical single girder configuration, offering a significant cost advantage over comparable double girder cranes.
- No Building Structure Required: As a ground-operating system, it eliminates the need for costly runway support columns and building modifications, resulting in a faster, more affordable installation.
- Efficient and Powerful Operation: Fully motorized travel and a high-performance hoist ensure smooth, rapid, and efficient movement of heavy loads, boosting productivity and reducing manual effort.
- Versatile Indoor/Outdoor Application: Designed with durable components and weather-resistant finishes (IP55 optional), this crane performs reliably in both indoor manufacturing environments and rugged outdoor stockyards.
- Enhanced Safety Features: Compliant with CE standards, it is equipped with a full suite of safety devices, including overload limiters, anti-collision systems, and robust braking, to ensure secure operations.
Application Scenarios
- Precast Concrete Yards: Ideal for lifting and moving heavy precast concrete segments, beams, and panels with power and precision.
- Steel Stockyards: Efficiently handles large steel plates, structural sections, and heavy coils in outdoor storage and processing areas.
- Heavy Fabrication and Assembly: Provides the lifting capacity needed for assembling large machinery, equipment, and heavy structural fabrications.
- Shipping Ports and Rail Yards: A cost-effective solution for loading and unloading heavy, oversized cargo from trucks and railcars.
- Major Construction Projects: Used in on-site laydown yards for handling large modules, building materials, and heavy equipment.
