法国波坦公司是世界著名专业塔机生产企业,FO/23B、H3/36B是其上个世纪最具代表性的产品。二十多年前,国内三大塔机生产厂引进了这项技术,自行生产FO/23B型、H3/36B型自升式塔机,该系列塔机在当时应该是国内最先进、最实用的建筑施工机械。然而二十多年后的今天,除了少数在起升、变幅、回转机构上采用新技术的塔机外,这两个型号的塔机或其衍生品仍然占据着国内塔机市场的半壁江山,而引进之初存在的某些技术难点继续困扰着这些塔机生产企业,有的企业还用不适当的方式掩盖存在的问题。现在逐一揭示和分析这些问题的关键,并简要提出解决问题的方法。
France Potain company is a world famous professional tower crane manufacturer, FO / 23B, H3 / 36B is the most representative product of its last century. Twenty years ago, the three major tower crane manufacturers in China introduced this technology to produce the FO / 23B and H3 / 36B jack-up tower crane. At that time, the tower crane was the most advanced and practical in China Construction machinery. However, after more than 20 years, apart from a few tower cranes that adopt new technologies in lifting, luffing and turning mechanisms, these two models of tower cranes or their derivatives still occupy half of the domestic tower crane market, The introduction of the beginning of some of the technical difficulties continue to plague these tower crane manufacturing enterprises, some companies also use an inappropriate way to cover up the existing problems. Now reveal and analyze the key points of these issues one by one, and briefly propose ways to solve the problem.
