??随着我国科技建设的不断推进, 我国在生产等各个领域的建设规模也在不断扩大,同时促进了我的提高。所以,先进的机械设备将会成为促进施工速度的重要保障, 同时也是保障工程质量的物质保证。起重机械在煤矿, 码头等实现机械化, 自动化以及提高劳动生产量方面发挥了重要作用。起重机械一般以间歇, 重复的方法进行工作,取物装置的起升, 下降或者平移等完成运送货物。在工作进行中,工作范围相对来说较大,且危险因素较多。因此, 在起重机的设计, 制造过程中, 设计参数和设计要素就相对重要,主要设计参考的几个要素包括:起重绳索,绞车及锚碇,轮胎起重机和汽车起重机, 缆索起重机, 桩基, 构件装卸运输与堆放等。设备管理是企业经营的重要环节,通过各种技术, 经济和组织等措施, 对现有设备进行规划, 设计, 使用, 维修, 改造, 直至完全报废等全过程的管理。我国对安全生产方面一直都相当重视, 但是在执行和客观的条件方面都有许多不确定的不安全因素, 尤其是在人为方面, 由于生产者忽视安全生产的作用, 往往会造成很大的安全事故。我们应该从这些相当重大的生产事故中吸取教训, 防患于未然, 最根本的最重要的就是从起重机械的设计和管理等一些方面做起, 保证产品的质量, 尽量减少事故的发生。关键词: 起升机构; 小车运行机构; 门式起重机 Abstract With the continuous advance of China's economic construction, manufacturing and other areas of the building are getting bigger, while promoting improvement in the level of mechanization. Therefore, advanced machinery and equipment has e an important guarantee to promote the construction speed, but also ensure the quality of the material guarantee. Lifting machinery in the mines, docks and other mechanization, automation, and improve labor productivity has played an important role. Lifting generally intermittent, repetitive approach to work, extract lifting devices, down or panning, etc. to achieve delivery of goods. In the course of their work, the scope of work is relatively large, and a lot of risk factors. So, in crane design, manufacturing process, design parameters and design elements is quite important, the main design elements of reference include: lifting rope, all kinds of pulleys, winches and anchor, mast, truck crane ponents such as transportation and handling. Device management is an important part of business, through a variety of technical, economic anizational measures for existing equipment planning, design, manufacture, installation, use, maintenance, alteration, until the retirement of the whole process of management. Management objective is to obtain a better job running effect, that is, we should give full play to the effectiveness of the device, but also the pursuit cycle cost o
