Top Running Overhead Crane: Versatile, Wide Application and Easy Maintenance
A “Top Running Overhead Crane” refers to a type of overhead crane where the trolley (the part that carries the hoist) runs on rails located on top of the crane’s structure. This design allows the crane to travel along the full length of the building or workspace, utilizing the overhead space more efficiently.
Product Types
Top Running Single Girder Crane
The Top Running Single Girder Crane is designed with diverse configurations to adapt to various industrial scenarios, including standard models for general workshops and warehouses, as well as low-headroom models for use in height-restricted facilities. Based on the actual on-site requirements, the product supports customized non-standard designs to meet specific operational needs. For detailed model selection and specifications, please refer to the product classification page.
Top Running Double Girder Crane
The Top Running Double Girder Crane features a dual-girder structure, offering higher load capacity (typically ranging from 5 to 500 tons) and enhanced stability, making it ideal for heavy-duty industries and complex working conditions. Its design improves span adaptability (up to 40 meters or more) and duty classification (A5–A7). The crane supports multi-point lifting coordination, variable frequency speed control, and remote monitoring functions. Specific configurations are determined based on load requirements, environmental conditions, and process demands, following precise calculations. For detailed technical specifications, please refer to the Double Girder Crane product catalog.
Top Running Overhead Crane Features
- High Space Utilization: The rail system is installed on the overhead crane beam structure of the facility, without occupying floor space. The crane operates with minimal blind spots, effectively increasing the overall space utilization of the facility.
- High Safety: It frees up more space for ground personnel movement and material transfer vehicles, ensuring a safer production process and reducing accident rates.
- Strong Load Capacity: The crane beam structure has high rigidity, strength, and fatigue resistance, allowing it to effectively support large crane loads (hundreds of tons) and ensure stable crane operation.
- High Impact Resistance: The structure can withstand various impact loads, seismic loads, and other additional forces, making the entire load-bearing system safer and more reliable.
- Stable and Durable Structure: The main load-bearing metal components of the crane are box girders welded from high-strength, calm steel plates. This design provides excellent overall stability, high structural rigidity, and suitability for heavy-duty loads. It also offers good manufacturability, making processing and fabrication easier.

Top Running Overhead Crane vs. Under Running Overhead Crane
| Dimension | Top Running Overhead Crane | Underhung Running Overhead Crane |
|---|---|---|
| Structural Design | The rail is installed on the overhead crane beam structure of the facility, with the crane running on top of the rail. | The rail is installed below the supporting beam at the top of the facility, with the crane fully suspended under the rail. |
| Lifting Capacity | High (up to 500+ tons), suitable for heavy loads (e.g., steel, shipbuilding, power plant construction, etc.). | Low (typically ≤16 tons), suitable for light loads (e.g., small component handling, equipment maintenance, and assembly in workshops). |
| Travel Distance | Suitable for long-distance operation, covering large factory lengths with a broader working area. | Travel distance is limited by the length of the I-beam, making it more suitable for small to medium-sized workshops. |
| Space Occupation | Occupies overhead space in the facility, requiring a higher net ceiling clearance above the rail. | Saves overhead space, suitable for workshop interiors where the ceiling has load-bearing structures. |
| Installation Complexity | More complex, requiring professional guidance and specialized equipment for installation, with a longer construction period. | Simpler installation, can utilize existing building structures, making installation faster and easier. |
| Initial Cost | High (due to support structures and installation expenses). | Low (leveraging existing structures, resulting in lower installation costs). |
| Maintenance Cost | Equipped with maintenance walkways, making equipment maintenance and part replacement easier. | No maintenance walkways, making maintenance more complex and part replacement more challenging. |
| Applicable Scenarios | Steel plants, shipyards, locomotive manufacturing, aerospace, large warehouses, etc. | Light-duty workshops, laboratories, repair rooms, low-ceiling factories. |
| Core Advantages | High load capacity, wide operating range, customizable designs (e.g., multiple hooks, intelligent control, etc.). | Low cost, space-saving, quick and easy installation. |
| Main Limitations | High cost, requires high-ceiling facilities, complex installation. | Low load capacity, limited operating range, higher maintenance difficulty. |
FAQ – Top Running Overhead Crane vs. Underhung Running Overhaed Crane
Which crane has a higher lifting capacity?
The top running overhead crane, with a maximum lifting capacity of over 500 tons.
Which crane is suitable for long-distance operation?
The top running overhead crane, ideal for large workshops with extensive coverage.
Which crane saves more space?
The underhung overhead crane, as it occupies less overhead space in the facility.
