The U-type double girder gantry crane is widely used for conventional cargo loading, unloading and hoisting tasks. It adopts an extended trolley track gauge design that broadens the internal clearance between support legs, making it ideal for handling large-sized goods including containers.
Different from A-type gantry cranes, this U-type structural design removes the need for a saddle frame. With a fixed lifting height, the whole machine features a lower overall height. The widened trolley track distance optimizes load dispersion and delivers more stable operation during working cycles.
Thanks to the optimized structural design, the crane boasts superior comprehensive performance and strong adaptability for various working scenarios. The reinforced support legs further enhance overall stability, enabling flexible free travelling on flat ground.
This U-type gantry crane is well-suited for routine lifting and cargo handling work at open freight yards and railway lines. The applicable ambient working temperature ranges from -25℃ to +40℃, with the average 24-hour temperature not exceeding +35℃.
At container terminals, the equipment is capable of transferring containers from vessels to storage yards or transport trucks. It flexibly handles containers of various specifications with fast turnover movement, greatly boosting overall operational efficiency.
Apart from container operation, the crane can also complete loading and unloading of bulk materials, large machinery and other heavy-duty goods. It serves as an efficient lifting solution for multiple industrial scenarios including steel mills and timber processing plants.
Optimized U-shaped Frame Structure: The integral U-shaped framework delivers outstanding bending and torsion resistance, effectively improving the equipment’s overall structural stability.
Responsive Control System: Achieves rapid system response and steady running states, helping enterprises improve operating precision and overall working efficiency.
Strong Heavy-load Lifting Performance: It excels in hoisting ultra-heavy workpieces such as ship components and wind power equipment.
Wide Span Coverage: It can span multiple tracks and working areas, enhancing operational flexibility and adapting to diverse and complex field conditions.
