翻译英文-起重机历史

毕业论文要用，机器翻译的不行，我英语实在太差，哪位高手帮忙翻译一下万分感谢，人名地名公司名不用翻译，一定要通顺。多谢各位朋友了。3天之内就要交。Wylie, which has already been mentioned, builtmechanical systems that proved their worth over many decades in stationary and mobile cranes. Other manufacturers wilL, of course, be introduced in duecourse as they appear. The period between 1940 and 1949 ends on a confident note. Peace was returning to the world and cranes were re-building the shattered nations rather than lifting destructive bombs into place. In the first volume of this series, 500 Years of Earthmoving, the author, Heinz-Herbert Cohrs, asked of this period "Was there anybody who was not building construction machines?" We, too, can now ask this same question about cranes. It is clear that engines were becoming more powerful, crane control systems (elec-tric, hydraulic andpneumatic) were becoming more sensitive and the spectrum of use had grown considerably. There were some very advanced slewing tower cranes on the market and new ways of using cranes were being developed around the world. Take yard cranes, for example, which turned out to be indispensable aids right until the end of the decade, and prepared the way for the much bigger machines to come!Picture 204: This pneumatically controlled MAN rail mounted crane was driven by a truck engine and could lift 6 tonnes at a 7 metre radius.Picture 205: The Wylie DL rope tension meter was introduced in 1948 and helped to monitor load moment. It was the forerunner of complex electronic systems.: 问提问者：网友 | 2017-02-02

前面提到的Wylie公司是一家机械系统制造公司，几十年来以制造固定式和移动式起重机而闻名。当然，按出现的次序，我们也会介绍其它厂商。1940年到1949年这段时间，市场逐渐恢复了信心。世界重返和平，人们不再用起重机将毁灭性炸弹吊到战场，而是用它来重建满目疮痍的国家。在《500 Years of Earthmoving》系列从书的第一卷中，作者Heinz-Herbert Cohrs就这段时间提了一个问题："还有谁不在制造建筑机械吗？"现在，我们也可以换成起重机提出同样的问题。显然，现在引擎更加强劲，起重机控制系统（电动、液压和气动式）更加灵敏，用途也更加广泛。市场上出现了一些非常先进的塔式回转起重机，而且世界各地还开发出了许多起重机的新用途。以移动吊车为例，到二十世纪四十年代末，它已成了不可或缺的辅助机械，并为更大型的机械的问世铺平了道路！图204：这种气动式MAN轨行起重机由卡车引擎驱动，提升重量可达7吨，起重半径达7米。图205：这种Wylie DL绳张力计于1948年推出，协助监测负载转矩。它是复杂电子系统的先驱。: 回答者：网友
