The choice of crane depends heavily on specific project needs.
Technical Features Comparison
The core technical specifications differentiate one 250-tonne mobile crane from another. Factors such as boom length, lifting capacity at various radii, and engine power significantly influence operational efficiency and suitability for specific tasks. The following table compares key features across different models:
| Feature | XCMG QAY260A | Tadano ATF 220G-5 | Grove GMK5250L-1 |
|---|---|---|---|
| Lifting Capacity (t) | 260 | 250 | 250 |
| Max. Boom Length (m) | (Not specified) | 68 | 70 |
| Max. Tip Height (m) | (Not specified) | 110 | 110 |
| Engine Type | Benz Diesel | Mercedes Benz | Mercedes-Benz OM471LA |
| Drive Type | All Terrain | All Terrain | All Terrain |
Note: Specific specifications may vary depending on the configuration of the crane. Always refer to the manufacturer’s documentation for precise details. Information on these models can be found on various platforms such as tradewheel.com and manitowoc.com (for Grove cranes).
Types of 250 Tonne Mobile Cranes
Within the 250-tonne class, several types of mobile cranes exist, each designed for specific applications. The key differentiators include their undercarriage design and terrain adaptability. This impacts maneuverability, stability, and suitability for various job sites.
| Crane Type | Description | Advantages | Disadvantages |
|---|---|---|---|
| All Terrain Crane | Highly maneuverable, suitable for various terrains. | Excellent versatility and mobility. | Potentially lower lifting capacity compared to other types. |
| Truck Crane | Crane mounted on a truck chassis. | High mobility on paved roads. | Limited off-road capability. |
| Crawler Crane | Crane with tracks, offering superior stability on uneven ground. | Exceptional stability, ideal for heavy lifting on challenging terrain. | Lower mobility compared to wheeled cranes. |
This information is often detailed on specialist crane websites such as cranepedia.com. The choice of crane type depends significantly on the terrain and the specific lifting requirements of the project.
Choosing the Right 250 Tonne Mobile Crane
Selecting the appropriate crane involves careful consideration of several factors. The project’s specific lifting requirements, including the weight of the load and the required lifting height and radius, are paramount. Terrain conditions at the job site must be assessed to determine the suitability of different crane types. Maintenance and operating costs, including fuel consumption and operator training, should also be factored into the decision-making process. Machinio.com provides a platform to compare different models and their associated costs.
Conclusion
250-tonne mobile cranes are essential tools in large-scale construction and infrastructure projects. Understanding the different types and their technical capabilities is crucial for successful project execution. By carefully considering the specific project requirements and comparing available models from various manufacturers, clients can choose the most efficient and cost-effective solution.
