Portable gantry crane is a kind of light and efficient lifting equipment, which is widely used in industrial production, logistics storage, construction and outdoor engineering. Its core components include foldable gantry, lifting mechanism, operating mechanism and control system. The use of lightweight and high-strength materials, such as aluminum alloy, reduces its own weight and is easy to carry and move. Its design allows quick assembly and disassembly and is suitable for flexible transfer between different sites. It has a variety of application scenarios, including material handling inside the workshop, cargo lifting for outdoor projects, lifting items for exhibitions and temporary activities, etc. A low cost, high efficiency lifting solution is provided.

It is a 275-ton crawler crane jointly produced by Hitachi and Sumitomo, which sets a new global standard with its high lifting performance and advanced technical characteristics. The maximum lifting capacity of 275 tons, the main arm length of 15.25 meters, with a strong lifting capacity and operational performance. The plan focuses on rapid assembly and disassembly, and adopts a "quick pull-out" system and a "hook-type" design, which simplifies the self-assembly process and reduces the labor intensity of side frame assembly. Environmentally friendly, its low-emission engines meet EU Phase III emission standards, demonstrating the crane's minimal environmental impact.

It is a high-performance crane produced by Kato, known for its excellent workability and economy. The overall model is designed to achieve a low center of gravity and improve the stability of about 5%, thus improving the efficiency of the operation and making it possible to complete more difficult operations. Two operation modes, fuel-saving mode and fast mode, are provided to adapt to different working conditions. Its superior loading height and operating range, as well as KATO's unique three-pump combined hydraulic technology, have increased the digging force by 10% and made the operation smoother. With its high efficiency, environmental protection, comfort and safety, it has become a popular crane choice in the market.
