22、有成功的例子，也有失败的教训。 20 世纪 90 年代以来，以我国起重机龙头企业太原重型机械厂和大连起重机厂为首，一些厂家开始与国外同行接触，进行技术合作，把经过实践检验成熟可靠的技术应用于新的产品中，为我国铸造起重机行业揭开了新的篇章。为了在国际起重机行业占有一席之地，我们还必须在引进吸收先进技术的同时，举一反三，积极探索铸造起重机的发展方向，以形成自己的特色和优势。起重机是指能在一定范围内垂直起升和水平移动物品的机械，具有动作间歇性和作业循环性，多用于人力不能完成的任务。桥式起重机：横架于车间、仓库和料场上空进行物料吊运的起重设备。由于它的两端坐落在高大的水泥柱或者金属支架上， 形状似桥，

23、所以又称“天车”或者“行车”。桥式起重机的桥架沿铺设在两侧高架上的轨道纵向运行，起重小车沿铺设在桥架上的轨道横向运行，构成一矩形的工作范围，就可以充分利用桥架下面的空间吊运物料，不受地面设备的阻碍。它是使用范围最广、数量最多的一种起重机械。 所以桥式起重机在室内外工矿企业、钢铁化工、 铁路交通、港口码头以及物流周转等部门和场所均得到广泛的运用。1.2 桥式起重机的发展方向概述随着工业的发展，桥式起重机日常趋向高速化大型化智能化方向发展。高速化：大型桥式起重机主起升机构的起升速度已达12mmin，付起升精选学习资料 - - - - - - - - - 名师归纳总结 - - - - - - -第

45、重机。智能化：整机电控配置先进，已发展到全部机构变频调速，检测手段先进，运行自动监控、自动跟踪、检测智能化，给维护检修提供了便捷。在起重机械上应用计算机技术，可以提高作业性能，增加安全性，以至实现无人自动操作。因此对于大型化的铸造起重机，主起升机构安全可靠性的设计就显得更尤为重要。否则一旦发生事故后果是十分严重的。1.3 桥式起重机的特点概述桥式起重机是桥架型起重机的一种，它依靠起升机构和在水平面内的两个相互垂直方向移动的运行机构，能在矩形场地及其上空作业，是工矿企业广泛使用的一种起重运输机械。它具有承载能力大，工作可靠性高，制造工艺相对简单等优点。桥式起重机一般有大车运行机构的桥架、装有起升

46、机构和小车运行机构的起重小车、电气设备、司机室等几大部分组成。外形像一个两端支承在平行的两条架空轨道上平移运行的单跨平板桥。起升机构用来垂直升降物品，起重小车用来带着载荷作横向移动，以达到在跨度内和规定高度内组成的三维空间里做搬运和装卸货物用。桥式起重机是使用最广泛、拥有量最大的一种轨道运行式起重机，其额定起重量从几吨到几百吨。最基本的形式是通用吊钩桥式起重机，其他形式的桥式起重机都是在通用吊钩桥式起重机的基础上派生发展出来的。精选学习资料 - - - - - - - - - 名师归纳总结 - - - - - - -第 2 页，共 49 页Delegates, staff: Hello! in
