Description
The Weihua U-shaped double-girder gantry crane is the high-end flagship product in Weihua Group's gantry crane series, named for its unique "U"-shaped structure formed by the legs and lower crossbeam. Unlike A-type (A-frame) and L-type (inverted L-shaped) legs, the U-shaped gantry crane features vertical legs, creating a wide passageway. This structural characteristic makes it ideal for handling large, long materials and containers.
As an important member of the double-girder gantry crane family, the U-shaped gantry crane combines the high load-bearing advantages of the double-girder structure with the large passageway of the U-shaped legs. The product range covers an ultra-wide range of lifting capacities from 5 tons to 1000 tons, spans from 18 meters to 50 meters, and working classes including A5, A6, and A7, meeting diverse operational needs from general freight yard loading and unloading to offshore wind power equipment hoisting.
In terms of structural design, Weihua's U-shaped double-girder gantry crane adopts a double-girder box-shaped welded structure, with two vertical legs connected to the lower crossbeam, forming an overall "U" shape. Compared to A-type gantry cranes, the U-shaped gantry crane eliminates the traditional saddle frame structure, resulting in a lower overall height for the same lifting height. Simultaneously, due to the larger trolley track gauge, the clearance over the legs can reach nearly 7 meters, making it particularly suitable for loading and unloading long, heavy cargo and containers.
In recent years, Weihua has continuously broken industry records in the field of U-shaped gantry cranes. In 2023, Weihua's independently developed and manufactured 550-ton new Chinese-style gantry crane successfully completed heavy-load testing in Guangdong, breaking the record for the largest tonnage of a double-girder U-shaped gantry crane in my country. In October 2024, Weihua's 1000-ton double-girder gantry crane was successfully put into operation at the Fujian Fuqing Jiangyin Port National Offshore Wind Power Research and Testing Base, further solidifying Weihua's technological leadership in the field of ultra-large tonnage U-shaped gantry cranes.
This product is widely used in industries such as machinery manufacturing, metallurgy and mining, power energy, railway transportation, ports and docks, and petrochemicals. It has irreplaceable application value, especially in the fields of offshore wind power equipment manufacturing, port container loading and unloading, and railway long and long cargo transportation.

Advantages
When purchasing a marine travel lift for sale, it is recommended to conduct a professional evaluation in the following four areas:
Spacious Load Clearance
The U-shaped vertical leg design provides an exceptionally wide leg span (nearly 7 meters of clearance) , allowing large cargo such as containers, wind power equipment, and bulky machinery to pass freely through the legs. This overcomes the space limitations of traditional A-type cranes .
Low-Profile Structural Design
By eliminating the saddle frame found in A-type gantry cranes, the U-type structure achieves a lower overall height for a given lifting height . This makes it highly adaptable to sites with height restrictions and simplifies the structural design.
Superior Stability & Structural Rigidity
The double-girder configuration combined with a large trolley track gauge delivers exceptional bending and torsional rigidity . This ensures stable load handling and even load distribution during heavy-duty operations, with proven capacity reaching up to 550 tons for extreme applications .
Flexible Operation & Precision Control
The crane supports multiple control options including ground pendant, wireless remote control, or operator cabin . Variable frequency drive (VFD) with PLC control enables soft starts/stops and precise positioning, while optional intelligent features
