The trend of lightweight design is spreading from road transportation to the field of lifting machinery. Shandong Zhenyuan Automobile Wheel Co., Ltd. has made significant progress in the research and development of lightweight wheels, successfully reducing the weight of heavy vehicle wheels from 46 kilograms to 25 kilograms, achieving a weight reduction of nearly 50%.
This breakthrough lightweight technology, at its core, lies in optimizing the structure and innovating material processes to minimize the self-weight of components while ensuring load-bearing capacity and safety. For cranes, especially the wheel sets (wheel sets) of mobile cranes, reducing self-weight means enhancing the overall mobility of the machine, lowering operational energy consumption, and increasing counterweights within the total weight limit potentially, thereby improving lifting performance.
This technical route provides a referenceable path for the lightweight design of the core operating components of cranes, including end beam wheel sets and trolley wheel sets, indicating that cranes will develop in a more efficient and energy-saving direction in the future.
