四绳抓斗主要是与桥式起重机和门式起重机配套使用,用于抓取各类松散的堆积物,进行装车、卸车、转运、加料等作业。由于抓斗大小不同,所抓取物料比重不同,我们通常把抓斗分为轻型、中型、重型、超重型,根据抓取物料选择所需要的抓斗。
工作开始时,支持钢丝绳将抓斗起吊在适当位置上,然后放下开闭钢丝绳,这时靠下横梁的自重迫使斗部以下横梁大轴为中心将斗部打开,当斗部开至两耳板的碰块相撞时,即斗部打开到最大极限。开斗时上横梁滑轮和下横梁滑轮中心距加大,然后支持钢丝绳落下,将已开的抓斗,落在要抓取的松散堆积物上面,再收拢开闭钢丝绳,将上横梁滑轮和下横梁滑轮的中心距恢复到原来的位置,这样就完成了抓取物料过程。在闭合的斗部里已装满了物料,最后同时提升支持钢丝绳和开闭钢丝绳,整个抓斗亦被吊起,经行车移动到所需卸料场地上,开斗卸下所抓取的物料。
