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.
