摘　　要：探讨了吊管机起吊重物时,同时具有高速和低速两档起吊速度的必要性及意义,并从原理和结构上提出了吊管机增加设计高速卷扬机液压系统的可实施性,从根本上解决了吊管机没有两档起吊速度的现状(目前吊管机只有一个低速),可以有效的提高吊管机作业的效率。We discussed the necessity and significance of having both high-speed and low-speed lifting speeds when the pipelayer lifts heavy objects,From the principle and structure,the pipelayer is proposed to increase the practicability of the hydraulic system of the hydraulic system of the high-speed hoist,Fundamentally solve the current situation of not having two lifting speeds,It can effectively improve the operating efficiency of the pipelayer.
