On April 3, the SDC90K8 container empty stacker, independently developed by Sany Heavy Industry, slowly rolled out of the factory — marking the birth of the world's first full hydraulic container empty container stacker. This groundbreaking machine is designed for use in ports, docks, railway stations, highway transfer centers, and container yards, where it efficiently handles and transships empty containers. As an essential accessory for shore bridges, field bridges, and front loaders, the SDC90K8 stands out with its high stacking capacity, fast handling speed, and superior maneuverability. Its compact design also saves valuable space, making it a versatile and efficient solution.
The SDC90K8 represents another major technological achievement from Sany. Officially launched in May 2005, the project saw its design completed by year-end. According to Liu Yuhua, the project leader, this model was the first in the world to integrate closed hydrostatic walking technology and hydraulic load sensing, offering greater efficiency compared to traditional hydraulic systems. The result is a machine that moves more smoothly, comfortably, and energy-efficiently, better suited to China’s operational needs. The stacker uses globally recognized brand components, ensuring top-tier performance and reliability.
To guarantee quality, Sany’s R&D team employed advanced techniques such as structural finite element analysis, dynamic simulation, modal analysis, and valve group testing. These methods ensured the machine met the highest standards of safety and durability. The SDC90K8 is not only easy to operate, with ergonomic features that enhance user comfort, but also boasts a sleek, compact design and high reliability. It is ideal for handling both 20-foot and 40-foot standard containers, with a maximum lifting capacity of 9 tons and a lifting height of up to 19,000 mm.
The successful development of the SDC90K8 fills a critical gap in the global market for full hydraulic container stackers. It is expected to drive industry innovation and potentially replace imported models. Soon, the machine will undergo national certification and is anticipated to hit the market in the second half of this year, marking a significant milestone for Sany and the broader logistics sector.
