港口采用门机双索荷花抓斗装卸生铁和矿石已有多年历史,随着生产的发展,越来越多的船舶采用了单索起重机(即独杆吊),这种独杆吊是否可用荷花抓斗来卸生铁呢?在缺乏先例可以借鉴的情况下,上海港务局四区的职工通过技术革新,针对港区作业对抓斗实用性强的要求,吸取单索平抓斗的特点,试制了一种单索生铁抓斗(图1)。通过生产实践,用这种抓斗与船舶吊杆来装卸生铁和矿石,取得了一定成效,现简要介绍如下。 Ports using double-hook lotus door crane loading and unloading of pig iron and ore has been for many years, with the development of production, more and more ships using a single rope crane (ie, single pole crane), this single pole crane is available lotus Grab to unload pig iron? In the absence of precedent to learn from the case, the Shanghai Port Authority staff in four districts through technical innovations, for port operations grab the practical requirements of the strong, draw single Saussure grab features, trial A single cable gripper (Figure 1). Through the practice of production, we have achieved some success by using this grab and the ship’s hanger to load and discharge pig iron and ore. The brief introduction is as follows.
