The 50 tons rubber tired gantry (RTG) crane is a high-performance material handling equipment specifically designed for efficient operations in container yards, ports, and logistics hubs. As a key player in the field of heavy-duty lifting, this crane combines excellent mobility, strong load-bearing capacity, and reliable performance to meet the demanding requirements of modern cargo handling. This 50 tons RTG crane stands out for its ability to handle containers of various sizes with precision and efficiency, significantly improving the throughput of storage and transshipment operations.

single girder 50 tons RTG crane
The single girder 50 tons RTG crane features a simplified yet robust structure, making it an ideal choice for medium-scale container handling scenarios. Its main girder is a single box-type structure made of high-quality low-alloy high-strength steel, which undergoes strict welding and heat treatment processes to ensure excellent mechanical properties and structural stability.
In terms of working principle, the single-girder design integrates the lifting mechanism, trolley traveling mechanism, and crane traveling mechanism onto a single main girder. The lifting mechanism adopts a high-performance hoist with a variable-frequency speed regulation system, allowing for smooth lifting and lowering of 50-ton loads, reducing the impact on the crane and the cargo. The trolley travels along the track on the main girder, driven by a gear motor with precise braking, ensuring accurate positioning of the load.
One of the notable advantages of the single girder 50 tons RTG crane is its compact structure, which occupies less space in the yard. This makes it suitable for yards with limited width or where space utilization is a priority. Additionally, its relatively lightweight design reduces the ground bearing pressure, minimizing the requirements for the foundation construction of the yard, thereby lowering the overall investment cost. Moreover, the maintenance of the single girder gantry crane is more convenient due to its simple structure, with fewer components to inspect and maintain, reducing downtime and maintenance costs.
This type of crane is widely used in small to medium-sized container yards, inland ports, and logistics centers where the handling volume is moderate and the requirement for space efficiency is high. It can efficiently handle 20-foot, 40-foot, and even 45-foot containers, adapting to the diverse needs of different cargo types.

double girder 50 tons RTG crane
The double girder 50 tons RTG crane is designed for large-scale and heavy-duty container handling operations, offering enhanced load-bearing capacity and stability. It consists of two parallel box-type main girders, connected by end carriages to form a rigid portal frame structure. The main girders are also made of high-strength steel, with reinforced sections at key stress points to withstand the heavy loads and complex forces during operation.
The working mechanism of the double girder 50 tons RTG crane is more sophisticated. The lifting mechanism is usually equipped with two hoists (main and auxiliary) to meet different lifting needs. The main hoist is responsible for lifting the 50-ton containers, while the auxiliary hoist can handle lighter loads or perform auxiliary operations, improving the flexibility of the crane. The trolley traveling mechanism is installed on the top of the two main girders, with a stable guide device to ensure that the trolley runs smoothly and does not deviate even under heavy loads. The crane traveling mechanism adopts a four-wheel or eight-wheel drive system, with large-diameter rubber tires that provide excellent traction and shock absorption, allowing the crane to move freely on the yard surface.
The double girder 50 tons RTG crane boasts superior load-bearing stability compared to the single-girder type. The dual-girder structure distributes the load evenly, reducing the stress on each girder and improving the overall safety and service life of the crane. It also has a larger working range, with a longer span and higher lifting height, enabling it to handle containers stacked in multiple layers (usually up to 4-5 layers) and cover a wider area of the yard. Furthermore, the double-girder design allows for the installation of more advanced control systems and safety devices, such as anti-sway systems, automatic positioning systems, and overload protection systems, further enhancing the operational safety and efficiency.
This crane is mainly used in large ports, deep-water terminals, and large-scale container yards with high handling volumes and high requirements for lifting height and span. It can efficiently handle a large number of containers in a short time, improving the operational efficiency of the entire logistics chain.

The 50 tons RTG Crane is widely applied in various fields related to container handling, including:

50 Tons RTG Crane For Ports and Terminals
As a core equipment in port container handling, the 50 tons RTG Crane works closely with quay container cranes (QCCs) to realize the “ship-yard-truck” transfer link. When containers are unloaded from ships by QCCs, the RTG Crane quickly receives and stacks them in the designated yard area. It can flexibly adjust its working path according to the berthing position of ships and the distribution of trucks, efficiently handling 50-ton heavy containers such as those loaded with machinery, bulk goods, or hazardous materials. For large ports with multiple berths, multiple RTG cranes can operate in coordination, forming a continuous handling line to shorten the ship’s berthing time and improve the port’s throughput capacity. Additionally, its rubber tires adapt to the port’s concrete or asphalt ground, avoiding damage to the yard surface while ensuring stable movement even in slightly uneven areas.

50 Tons RTG Crane For Container Yards
In container yards, the 50 tons RTG Crane undertakes the key tasks of container storage, retrieval, and yard rearrangement. It adopts scientific stacking strategies—usually stacking 4-5 layers for standard containers—to maximize the yard’s storage density. When retrieving containers, it can accurately locate the target container through its precise positioning system, even in complex stacking scenarios (such as retrieving containers in the middle or bottom layers). For yards with frequent container turnover, the crane’s fast lifting and traveling speeds (up to 30 m/min for traveling) ensure that the average handling time per container is controlled within a short range. It also supports yard planning optimization: by flexibly adjusting the stacking area, it helps yards cope with peak periods of import and export containers, reducing the risk of yard congestion.

50 Tons RTG Crane For Logistics Hubs and Inland Ports
In logistics hubs and inland ports that integrate road, rail, and waterway transportation, the 50 tons RTG Crane plays a vital role in “multi-modal transport connection”. When containers arrive by train or inland ships, the crane efficiently transfers them to trucks for “last-mile delivery”, or stacks them temporarily for cross-modal transshipment. Its rubber-tired design eliminates the need for fixed rails, allowing it to operate freely between railway lines, truck parking areas, and inland ship berths. For example, in inland ports along rivers, it can handle containers unloaded from barges and directly load them onto trucks bound for nearby industrial zones, shortening the transshipment cycle by 30%-40% compared to traditional rail-mounted cranes. It also supports the handling of special containers such as refrigerated containers or open-top containers by matching corresponding spreaders.

50 Tons RTG Crane For Industrial Parks
In industrial parks dominated by heavy industry (such as machinery manufacturing, automobile production, and petrochemicals), the 50 tons RTG Crane is used for handling large-sized production equipment, raw material containers, and finished product modules. For instance, in an automobile manufacturing park, it can lift 50-ton auto body stamping dies or engine assemblies from containers and transport them to the production line, ensuring the smooth supply of key production components. In petrochemical parks, it handles large chemical raw material containers (such as liquid chemical tanks with a net weight of 50 tons) with stable lifting performance, avoiding leakage risks caused by jitter during handling. Its compact structure (especially the single-girder type) is suitable for the limited operating space in industrial parks, enabling it to work in areas between workshops or near production lines without interfering with other equipment operations.
