6、靠性、舒适感和美学等问题。而对现代电梯而言，应具有高度的安全性。事实上，29电梯上已经采用了多项安全保护措施。在设计电梯的时候，对机械零部件和电器元件都采取了很大的安全系数和保险系数。然而，只有电梯的制造，安装调试、售后服务和维修保养都达到高质量，才能全面保证电梯的最终高质量。在国外，已“法规”实行电梯制造、安装和维修一体化，实行由各制造企业认可的、法规认证的专业安装队伍维修单位，承担安装调试、定期维修和检查试验，从而为电梯运行的可靠性和安全性提供了保证。因此，可以说乘坐电梯更安全。美国一家保险公司对电梯的安全性做过认真地调查和科学计算，其结论是：乘电梯

7、比走楼梯安全5倍。掘资料统计，在美国乘其他交通工具的人数每年约为80亿人次，而乘电梯的人数每年却有540亿人次之多。1.2电梯的国内外发展状况29在经济不断发展，科学技术日新月异的今天，楼的高度已和经济发展同样的速度成长起来。作为建筑的中枢神经，电梯起着不可或缺的作用，电梯作为建筑物内的主要运输工具，像其他的交通工具一样，已经成为我们日常生活的一个不可缺少的组成部分。一个国家的电梯需求总量，主要受其经济增长速度、城市化水平、人口密度及数量、国家产业结构等综合因素的影响。在全球经济持续低迷的情况下，我国国民经济仍然以较高的速度持续增长，城市化水平不断提高。

8、这从客观上导致了我国电梯行业的空前繁荣景象，我国已经成为全球最大的电梯市场。上世
