In 1958, we produced China’s first crawler bulldozer through joint efforts under Chairman Mao’s call of “Construct China with Yugong Spirit”, which established China’s first bulldozer brand – “Yishan”. In the past half century, with the dream of “Enrich the people and empower the country”, Yishan branded bulldozers have created a series of miracles and contributed a lot to the construction of new China.
