Description
The U-type outdoor gantry crane double girder is mainly for general loading, unloading, and lifting operations. It has increased the design of the small trolley track gauge, resulting in a larger legroom and suitable for handling larger items like containers, etc. Due to its structure, this gantry crane eliminates the need for a saddle frame compared to the A-type gantry crane.
With a fixed lifting height, the overall height of the machine is lower than the A-type gantry crane. And the rail distance of its electric trolley is long, which means better operational stability and load distribution. All the design makes it an excellent performance and adaptable to multiple working sites. Its supporting legs increase stability and allow the equipment to move freely on the ground.

Advantages
When purchasing a marine travel lift for sale, it is recommended to conduct a professional evaluation in the following four areas:
Oversized Load Clearance
The U-shaped leg design provides a 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—a key advantage over 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 , offering greater adaptability in sites with height restrictions.
Superior Stability & Load Distribution
The double-girder structure combined with a large wheelbase delivers exceptional bending and torsional rigidity , ensuring stable load handling and even load distribution for heavy-duty operations up to 50 tons .
Versatile Operation Control
The crane supports flexible control options including ground pendant, remote control, or operator cabin . Variable frequency drive (VFD) technology enables smooth soft starts/stops , while optional intelligent features like anti-sway and auto
