Introduction to 50t Rail Traveling Double Girder Gantry Crane
A 50t rail traveling double girder gantry crane is a robust and versatile lifting solution designed for heavy-duty applications in various industries. Characterized by its double girder configuration and rail-based movement system, this crane type offers exceptional stability, high lifting capacities, and precise load handling. As a pivotal asset in construction, manufacturing, shipping, and logistics sectors, understanding its pricing structure, technical specifications, and customization options is crucial for informed procurement decisions. This comprehensive guide delves into all aspects of the 50t double girder gantry crane, with a special focus on Dongqi Crane’s offerings, to help you select the ideal equipment for your operational needs.
Key Technical Specifications
When evaluating a 50 ton double girder gantry crane, several technical parameters demand careful consideration to ensure optimal performance in your specific working environment. The following table outlines the core specifications commonly associated with these cranes:
| Parameter | Specification Range | Details & Applications |
|---|---|---|
| Lifting Capacity | 50 tons (main hook) | Some models feature auxiliary hooks (e.g., 10-ton capacity) for multi-purpose lifting . |
| Span | 18-35 meters | Customizable to fit the width of your work area . |
| Lifting Height | 6-30 meters | Dictates maximum hook elevation; customizable based on facility clearance . |
| Work Duty Class | A5 to A8 | A5 (heavy duty) to A8 (severe duty); indicates durability for usage intensity . |
| Lifting Speed | ~5.9 m/min (main hook) | Varies by model; affects operational efficiency . |
| Travel Speed | ~38.5 m/min (crane) | Impacts transit time across the work area . |
| Power Supply | 3-Phase, 380V, 50Hz | Standard industrial power; other configurations possible . |
| Control Methods | Pendant, Cabin, Remote | Offers operational flexibility and safety . |
| Track Type | P43, QU70, or QU80 | Selected based on wheel load and foundation requirements . |
Beyond these core parameters, it’s important to consider the crane’s traveling length (the length of the installed track) and the ambient temperature range it can operate in, typically from -25°C to 40°C, ensuring suitability for outdoor applications .
Price Analysis of 50t Double Girder Gantry Cranes
The price of a 50t rail traveling double girder gantry crane is not a fixed figure but varies significantly based on configuration and customer-specific requirements. For a standard double girder gantry crane with a 50-ton capacity, the price range generally falls between $15,000 and $130,000 . However, for more specialized types like a 50-ton Rail-Mounted Gantry (RMG) crane used in container yards, the investment can be substantially higher, ranging from $500,000 to $1,000,000 .
Several key factors contribute to this wide price range:
- Span and Lifting Height: Longer spans and greater lifting heights require more material and a structurally robust design, directly increasing the cost .
- Duty Class: A crane built for severe duty (A7, A8) with more intensive use cycles will be priced higher than one for standard heavy duty (A5) due to the need for more durable components .
- Control Systems: Basic pendant control is standard. Upgrades to cabin control or wireless remote control systems will add to the overall cost .
- Component Quality: Cranes equipped with internationally recognized, high-quality components (e.g., Siemens electrical parts) may command a premium due to enhanced reliability and performance .
- Customization: Any non-standard requirements, such as special lifting attachments (like hooks or spreaders), anti-sway systems, or environmental protections, will influence the final price .
- Power Supply System: The choice between a cable reel or a busbar/sliding line power supply can also affect the cost .

- Railway Transport Yards: They are employed for loading and unloading heavy items from rail cars, making them crucial for logistics and freight operations .
How to Select the Right 50t Gantry Crane
Selecting the appropriate crane requires a thorough assessment of your operational needs. Here is a guide to the key considerations:
- Define Your Lifting Requirements: Confirm the maximum weight of the loads, including any future needs. Also, determine if you require a single hook or multiple hooks (e.g., 50/10 ton configuration) for different lifting tasks .
- Measure Your Site Dimensions: Accurately determine the required span (distance between rails) and lifting height. An oversized span can impact the crane’s overall stability and cost, so it’s important to choose dimensions that adequately cover the work area without excessive overkill .
- Analyze Your Work Duty Cycle: Estimate how many hours per day and how many lifting cycles per hour the crane will perform. This will help determine the necessary work duty class (e.g., A5, A6, A7), which ensures the crane is built to withstand your specific usage intensity .
- Assess the Operating Environment: Identify whether the crane will be used indoors or outdoors. For outdoor applications, consider factors like wind loads, ambient temperature, and potential exposure to corrosive elements, which may require additional features or protective coatings .
- Choose Control and Power Preferences: Decide on the preferred control method (pendant, cabin, or remote) based on operator safety and convenience. Also, verify the available power supply at your site .
- Plan for Installation and Maintenance: Ensure your site is prepared for the installation of rail tracks and that you have a plan for routine maintenance. Inquire with the supplier about the availability of installation services, spare parts, and after-sales support .
