The Sanzheng beams, also known as the Chinese bridge crane or the Zhejiang crane, have been used for over 2,000 years in China. These beams were once used to lift heavy loads and transport goods across rivers and other bodies of water. However, with the advancement of technology, the Sanzheng beams have become obsolete. Today, they serve as a symbol of China's cultural heritage and craftsmanship.
