41 Ton Rail Mounted Gantry Crane - RMG Crane For Sale to Uzbekistan

Container gantry crane or rail mounted gantry crane, a type of heavy duty gantry crane applied for loading and unloading containers. It is very widely used in the port, dock, wharf, etc. Enough lifting height, long span length, powerful loading capacity make container crane easily and efficiently move containers. 

41 Ton Container Gantry Crane for Sale to Uzbekistan

• One set of RMG (rail mounted gantry) crane of 41 ton lifting capacity for container handling was manufactured by DQCRANES, delivered to Uzbekistan and put into operation in Uzbekistan.
• Our customer is the operator of the new intermodal container terminal located near the border. The terminal is designed for the container traffic from Asia or Eastern Europe to Western Europe and back. The containers will be reloaded at the terminal due to different rail track widths.
• The project includes a series of improvements that are required to provide an increase in intermodal capacity that will accommodate increasing terminal throughput, while reducing rail traffic from the surrounding communities.
• Comparing our quotation and design solution of RTG crane and RMG crane, our customer chose the RMG cranes. These cranes will be equipped with the latest container handling technologies and will have the capability of handling approximately 20 boxes per hour.

41 Ton RMG Container Gantry Crane Designs:

• This 41 ton Container Gantry Crane, main beam adopts Q235B carbon structural steel, Three-layer painting, Electric winch trolley uses Double drum winch trolley with reducer, drums, motors.
• Insulation grade F class. Two sets lifting mechanism connected by rigid shaft to ensure simultaneous lifting. Four rope underslung to connect with four lifting points of container spreader.
• The most advanced Siemens technology has been used for the control system of this RMG crane therefore in the future the crane has the potential to become fully automated. 

Difference between RTG Crane and RMG Crane:

To reduce loading and unloading times of large container vessels the container storage area (container yard) needs to be managed in the best possible and most efficient way. Depending on the degree of automation in modern container terminals this can be managed by two types of container management cranes: Rubber Tired Gantry Cranes (RTG) or Rail Mounted Gantry Cranes (RMG).
 

• RTG cranes, as the name indicates, come equipped with rubber tires that promote free movement of the crane through the container yard. However, the rubber tires have their own limitations with regard to the size and lifting ability of the RTGs. On the other hand, the RMG cranes are designed to move on rails and hence, they cannot be made to move freely around stacks in the container yard. However, because the RMGs are equipped with steel wheels, they can carry greater weight compared to RTG cranes.
• The higher load-bearing capability of the steel-wheeled RMG cranes makes them an option that can be modified very easily in terms of design. You can get a number of rail configurations installed to the RMG cranes to promote its versatile use in an intermodal container yard. An RMG can cover eight rail tracks as well as the stacking sections. Notably, they can be made to reach drive lanes for trucks as well.
• Because of the limitations of the engine generator system, the RTG's hoisting speed should not be excessive; otherwise, the rubber tyred gantry crane's engine may stall or speed up. RMG, on the other hand, uses the power of the electric network system directly, and it has better mechanical properties in terms of starting, braking, and lifting and falling heavy loads. The hoisting mechanism, trolley mechanism, and cart mechanism may all run quickly when the run distance is long. 
• RTG can make a 90-degree turn to work in another field; however, the friction between the tire and the ground on both sides of the running bridge is highly different, making it easy to deviate; as a result, it must be corrected on a regular basis, otherwise safety mishaps will occur. RMG can only walk along a fixed track and cannot perform transfer field operations, however it does not need to correct a deviation.

 
In comparison, although rail mounted gantry cranes were introduced late in China, they have the advantages of high technical performance, high loading and unloading efficiency, low operation cost, high yard utilization rate, convenient operation and maintenance, and easy automation. Furthermore, the span and overhang distance of RMG can be customized to meet the requirements of various yard operations. Predictably, rail mounted gantry cranes will eventually replace rubber tyred gantry cranes as the most powerful loading and unloading machinery in container terminals. 

Selecting The Right RMG Crane for Your Application!

When looking for a RMG gantry crane, you should take several things into consideration so as to select an appropriate gantry crane for your application, including but not limited to your required lifting capacity, lifting distance, hook coverage area, lifting frequency, working conditions, your budget and some other safety concerns. After considering these issues, you will surely have a proper evaluation of your material handling needs.
