目前世界各大港口集装箱码头堆场作业通用的机械有2种:轨道式龙门吊和轮胎式龙门吊,其中占绝大部分的是轮胎吊。据不完全统计,轮胎吊倒箱单箱平均耗油1.2L,耗时1.5min,目前许多集装箱码头出口箱翻倒率为15%左右。对年出口150万TEU的码头来说,仅仅因为出口倒箱将额外耗油27万L和5625h的无效作业时间,这实在是一笔不少的损失。集装箱装卸费一般采用装卸包干费的办法,这部分成本只能是码头自己消化。因此,减少倒箱是码头重点挖掘的潜力之一,可以 At present, there are two types of machinery that are commonly used in container yard operations in major ports around the world: orbital gantry cranes and tire gantry cranes, of which tire cranes account for the vast majority. According to incomplete statistics, the average fuel consumption of a single box of tire hanging boxes is 1.2L, which takes 1.5min. At present, the turnover rate of many container terminals is about 15%. For terminals that export 1.5 million TEU per year, this is a significant loss simply because of the additional fuel consumption of 270,000 L and 5625 hours of fuel consumed by exporting. Container handling fees generally use the method of handling fees, this part of the cost can only digest the pier itself. Therefore, reducing the drop box is one of the potentialities tapped at the docks, yes
