近年来,一些主要工业国家生产的内燃叉车广泛采用液力传动,以改善叉车的牵引性能,简化操作,并提高装卸效率。如美、日、西德、英等国的5吨以上大中型叉车几乎全部采用液力传动,3吨以下的小吨位叉车液力传动也用得相当普遍。我国是从1964年开始研制液力传动叉车的,到1965年由大连铲车厂与我所联合设计试制成CPQ-5型内燃叉车。但由于工艺困难,没有成批生产。到1973年,我所设计试制成一台5吨液力传动的内燃叉车,接着大连铲车厂和合肥重机厂于今年又分别试制成一台5吨的和一台3吨的。
In recent years, a large number of internal combustion forklifts produced in major industrialized countries have adopted hydrodynamic transmissions to improve the traction performance of forklift trucks, simplify operations and improve handling efficiency. Such as the United States, Japan, West Germany, Britain and other countries more than 5 tons of large and medium-sized forklifts almost all hydraulic transmission, 3 ton following small tonnage forklift hydraulic transmission is also used quite common. Our country started to develop the hydraulic transmission forklifts from 1964, and was jointly designed and manufactured into a CPQ-5 internal combustion forklift by Dalian Forklift Works in 1965. However, due to process difficulties, there is no mass production. By 1973, I designed and manufactured a 5 tonne hydraulic forklift truck. Then, Dalian Forklift Works and Hefei Heavy Machinery Factory tried to produce one 5 tonne and one 3 ton respectively this year.
