第1章 前言

1.1国内外起重机发展概况

起重运输机械行业在我国从上世纪五六十年代开始建立并逐步发展壮大，该行业已形成了各种门类的产品范围和庞大的企业群体，服务于国民经济各行业。随着我国经济的快速发展，起重运输机械制造业也取得了长足进步。2005年起重运输机械行业销售额达到1272亿元，“十五”期间平均每年增长超过30％，2006年依然保持着持续增长的态势，目前市场前景非常好。近年来，国家重点发展能源（其中煤炭工业迅猛发展，起重运输机械制造业将提供所需的竖井提升设备、斜井防爆下运带式输送机、防爆移置式带式输送机、装车机、露天矿连续开采输送设备、用于洗选设备的各种输送设备等）、电力（各种电站专用桥式/门式起重机、料场用物料搬运装卸设备、输煤给煤栈桥内物料输送设备、环保排灰输送设备、水电站用闸门启闭机械、升船机、核电站废料处理专用起重机等将有较大需求）、石化（起重运输机械制造业将提供所需的自动灌装和包装码垛设备、仓储专用设备、厂内和车间内物料搬运装卸设备等）、冶金（对各种冶金起重机、厂内和车间内物料搬运装卸设备、料场堆取料与混匀料设备等将有较大需求）、造船、交通等工业领域（需要大量的高效、节能、低污染、智能化、柔性化、成套化的物料搬运装卸设备）。
