一、大中型汽车吊急待开发汽车超重机(也称汽车吊)是为国民经济建设各部门服务的一种常用的工程机械。我国生产汽车吊开始于六十年代初期。一九八○年全国能生产16吨以上汽车吊的厂家有五、六个,年产量300多台。七十年代末、八十年代初,研制20吨、25吨、50吨以及更大吨位的汽车吊,但至今产量廖廖无几,不能满足市场需要。据初步调查,全国每年大约需要各种不同吨位的汽车吊8000台左右,目前全国生产汽车吊的主要企业只有十四、五家,一九八六年的总产量大约在3500台左右,再加上其他一些不知名厂点的产品,总产量不超过4000台,由此可见,汽车吊生产正处于供不应求的发展阶段。
First, large and medium-sized car hung urgent development Automobile overweight machine (also known as car crane) is a commonly used construction machinery for the national economic construction departments. China’s production of car crane started in the early sixties. In 1980 the country can produce more than 16 tons of crane cranes manufacturers have five or six, the annual output of more than 300 Taiwan. In the late seventies and early eighties, the development of cranes of 20 tons, 25 tons, 50 tons and larger tonnage has so far failed to meet the needs of the market. According to a preliminary survey, about 8,000 car lifts of various tonnage are required each year in the country. At present, there are only 14 or 5 main car manufacturers in the country. The total output in 1986 is about 3,500 units. On some other unknown product point of the plant, the total output does not exceed 4,000 units, we can see that the car hanging production is in short supply of development stage.
