建筑施工中所用的推土机有向大功率重型发展的趋势,如苏联Д-385A 型推土机,其发动机功率为250马力,生产率为1500米~3/班。过去我国所用的推土机多从国外进口,其中以苏联 C-100和 C-80型最多。在自力更生的方针指导下,为满足经济建设的需要,58年天津建筑机械修造厂开始仿 C-80型底盘制成移山-80型推土机;58年开始,红旗-100拖拉机也已在农机部鞍山拖拉机厂成批生产;宣化、杭州、成都、廈门等地的工程机械厂,也把东方红-54型拖拉机改装为推土机。
The bulldozer used in construction has a tendency to develop towards heavy power. For example, the Soviet Д-385A bulldozer has an engine power of 250 horsepower and a productivity of 1500 meters to 3/shift. In the past, bulldozers used in our country were imported from abroad, of which Soviet Union C-100 and C-80 were the most. Under the guidance of the principle of self-reliance, in order to meet the needs of economic construction, the 58th Tianjin Construction Machinery Repair Factory began to imitate the C-80 type chassis to make the Yishan-80 bulldozer; in the 58th year, the Red Flag-100 tractor has also been in the Ministry of Agricultural Machinery. Anshan tractor factory mass production; Xuanhua, Hangzhou, Chengdu, Xiamen and other places of construction machinery factory, also Dongfanghong-54 tractor converted to a bulldozer.
