起重机的发展、机械运用、机械原理(中文3200字,英文1900字)
一、起重机发展
随着近年来我国大型基础设施建设、能源、房地产、石化工业和造船工业等
行业的快速发展,工业生产规模不断扩大,生产效率日益提高,以及产品生产过
程中物料装卸搬运费用所占比例逐渐增加,促使大型或高速起重机的需求量不断
增长。起重量越来越大,工作越来越频繁,并对能耗和可靠性提出更高的要求。
起重机已成为自动化生产流程中的重要环节。起重机不但要好用,容易维护,操
作方便,而且安全性要好,故障要少,平均无故障工作时间要长。可靠性是国际
市场产品竞争的焦点,国外许多大公司都制定了可靠性内控标准。我国起重机的
性能要赶超世界先进水平,最关键的是要改变传统的思维理念,提高可靠性,使
起重机具有优异的耐久性、无故障性、维修性和使用经济性。

large-scale infrastructure construction, energy, real estate, petrochemical industry
and shipbuilding industry, and so, continues to expand the scale of industrial
production, the proportion of increasing efficiency of production, and production
process of material handling expenses increased, the increasing demand to make
large or high-speed crane. Weight is more and more big, work more and more
frequently, and on the energy consumption and reliability of proposed higher
requirements. Crane has become an important part of the automation production
process. Crane is not only better use, easy maintenance, convenient operation and
better security, fault less MTBF working hours to Long. Reliability is the focus [版权所有:http://DOC163.com]
of international competition in the product market, many foreign companies have
developed internal control standards for reliability. The crane performance to
catch up with the world advanced level, the key is to change the traditional
concept of thinking, improve the reliability and the crane has excellent durability,
trouble free, maintainability and use economy. [资料来源:http://Doc163.com]
