液压大钳自上世纪70年代应用以来,为石油钻井行业做出了巨大贡献,降低了钻井工繁重的起下钻、下套管紧扣、卸扣的体力劳动强度,受到了操作工的欢迎。液压大钳本身也进行了几次结构和技术改进,液压大钳的运行可靠程度也日趋完善。但是,液压大钳的本质化安全未得到根本性的改变,在使用过程中时常威胁到操作者的安全,甚至付出了生命的代价,给企业带来巨大的经济损失。
Hydraulic pincers have made great contributions to the oil drilling industry since their application in the 1970s, reducing the heavy labor of drilling workers to drill, casing and buckle, and are welcomed by operators. . Hydraulic tong itself has also carried out several structural and technical improvements, the hydraulic pliers operating reliability is also maturing. However, the essential safety of the hydraulic tongs has not been fundamentally changed, which often threatens the safety of operators and even the cost of life during the operation, which brings huge economic losses to the enterprise.
