7、模越来越大，楼层越来越多，对电梯的可靠性、舒适感和美学等方面的要求也有了更高要求。电梯是集机电一体的复杂系统，不仅涉及机械传动、电气控制和土建等工程领域，还要考虑可靠性、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，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

8、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。.专业word可编辑
