单箱梁岸边集装箱起重机自行式小车总成轻型结构形式

由于岸边集装箱桥式起重机的速度不断高速化,外伸距及起升高度的不断增加,吊具下额定起重量不断增大,要求运行小车自重越来越轻。文中所介绍的单箱梁自行式小车,通过对其结构及机构的优化设计,使其质量大为减小,制造和使用成本大为节约,符合节能减排环保经济的发展方向。这些优点加之新技术,都将提高产品的综合竞争力。

Light assembly structure of self-propelled trolley for single box-girder quayside container cranes

As speed of the quayside container crane is continuously increased,the gradual increases in outreach distance,lifting height and the rated lifting capacity under the spreader require lighter and lighter self-weight of the trolley.For the single box-girder self-propelled trolley described in the paper,the self-weight is greatly reduced,thus significant saving on manufacturing and use cost is gained through the optimization of the structures and mechanisms,which is in line with the energy-saving environmental...
