1.概述目前装卸废钢大部分都是使用电磁吸盘,电磁吸盘对废钢轻薄料,松散料吸取效率低,一只1.65米吸盘一般一次只能吸200~300kg。国外在抓取物料方面发展了一种新型液压抓斗(Motot—Powered Grabs)。1984年前国内没有类似的装备,也未引进该项产品。因此,我们仅根据国外有关抓斗的样本自行进行了设计研制,并在1984年9月
1. Overview At present, most of the loading and unloading scrap uses electromagnetic sucker. The electromagnetic sucker is light and thin with scrap, and the loose material has low absorption efficiency. A sucker with a diameter of 1.65 meters can only absorb 200-300kg at a time. A new type of hydraulic grab (Motot-Powered Grabs) has been developed abroad to capture materials. Before 1984, there was no similar equipment in China and the product was not imported yet. Therefore, we conducted the design and development on the basis of only the foreign samples of the grab, and in September 1984
