Based on the legs configuration, there are A-type and U-type double girder gantry crane and here are their introduction.
A-Type Double Girder Gantry Crane
The A-type gantry crane gets its name from the shape of its legs, which resemble the letter “A”. It typically consists of two vertical legs, connected at the top by a horizontal beam resembling an “A” shape.


A-type gantry crane is known for its significant height and span capabilities. It is suitable for applications where a high lifting height and wide coverage area are required. Due to its robust “A” frame structure, it offers excellent stability even under heavy loads. It can be customized with various lifting mechanisms like wire rope hoists, electric chain hoists, or other lifting devices, making it versatile for different industries.


A-type gantry cranes find applications in environments such as shipyards, construction sites, manufacturing plants, and warehouses where heavy and bulky items need to be lifted and transported over a large area.
U-Type Double Girder Gantry Crane
The U-type gantry crane gets its name from the U-shaped legs. It consists of two parallel vertical legs, connected at the top by a horizontal beam resembling a “U” shape. They are relatively easier and quicker to install compared to some other gantry crane types. U-type gantry cranes are commonly used in settings like workshops, storage yards, and factories where heavy loads need to be moved efficiently.


In summary, the choice between A-type and U-type double girder gantry cranes depends on your specific operational requirements, available space, and budget considerations. Consulting with a professional crane supplier like Aicrane can help you make an informed decision based on your unique circumstances.
Rubber tyred gantry crane
The rubber tyred gantry crane, also known as a rubber tire gantry crane (RTG crane), stands as a mobile gantry crane. With a lifting capacity of 50 tons, it is an essential equipment for a range of engineering tasks such as hoisting and transferring concrete beams, assembling hefty loads, and accurately positioning pipelines. This versatile crane can be designed as either a single girder or double girder gantry crane.
Different Types and Usage of Rubber Tyred Gantry Crane



Unlike its rail-mounted counterparts, the RTG crane employs a tire group for movement, granting it the freedom to traverse in multiple directions. This inherent feature amplifies the crane’s operational flexibility, allowing it to handle various materials through the use of specialized lifting attachments.

Furthermore, the crane is equipped with a steering system to ensure seamless maneuvering. The steering techniques of the RTG crane encompass straight movement, oblique movement, 90° lateral movement, Ackerman steering, pivot steering, forward swing, and retral swing.
Rail mounted gantry crane
The 50-ton rail-mounted gantry crane (RMG) is a heavy-duty industrial crane primarily used in container terminals, rail yards, and intermodal facilities for the efficient handling of containers. What sets the rail mounted container gantry crane apart is its unique ability to travel along a fixed rail system, providing exceptional stability and precision in container movement.

Equipped with a powerful hoisting system, this crane is capable of lifting and positioning containers weighing up to 50 tons. Its sophisticated control systems ensure smooth and accurate operations, allowing for precise container stacking and retrieval. This makes it an indispensable tool in high-volume container handling facilities.

Aicrane provides different kinds of container spreader. They are simple container spreader, electric rotary telescopic single point spreader, single point spreader, spreader with four points, beam container spreader, spreader with four pulleys, upturn spreader, and upper rotating electric telescopic spreader, etc. These container spreaders will suit your operation needs.

If you are not certain what kind of a crane you need, contact us and we will give you reliable and professional instructions.
In order to ensure the corrosion resistance of the crane, we will perform the following treatments: First, for the steel plate of the crane, we will make shot blasting and spray epoxy zinc-rich primer painting after cutting.
Secondly, there will be base coat, middle coat, finish coat, three layers painting totally. All have high corrosion resistance, strong adhesion features, and a total thickness of 105 micron to ensure that it reaches the ISO standard derusting grade Sa2. Finally, we will design rain cover for motors, electrical appliances, and lifting parts to avoid the entry of rainwater.
Documents: Crane instruction, certificate of qualification (including motor, reducer, brake, steel wire rope, hook group, drum group, wheel group, overload limiter, limiter, electrical components and crane, etc.), steel material testing list and crane maintenance manual;
Drwaings: General drawing, trolley assembly and trolley running mechanism drawings, assembly drawing of vulnerable parts (such as wheel group, drum group, hook group, pulley group, coupling, drive shaft, etc.), electrical schematic diagram, wiring layout and important electrical component drawing, etc.
- Short circuit protection: The main power circuit is set with automatic air switch, as the crane short circuit protection. The control loop is equipped with a small capacity automatic air switch for short circuit protection.
- Voltage loss protection: The circuit structure has the function of voltage loss protection. When the power is restored after the power failure, the crane must press the start button to restart the operation, eliminating the possibility of self-operation of the crane when the power is on.
