摘　　要：某举升系统在举升到位后开夹钳下放重物时,出现开夹钳载荷较大的情况,存在夹钳打不开的风险。该文对开夹钳载荷较大的原因进行了分析,提出了举升液压系统相应改进措施,并进行了试验验证,降低了开夹钳的载荷,避免了夹钳打不开的风险,提高了系统可靠性,为举升液压系统设计提供指导。When a lifting system opens the clamp to lower heavy objects after lifting in place,the load of opening the clamp is large,and there is a risk that the clamp will not open.This paper analyzes the reasons for the large load of the opening clamp,puts forward the corresponding improvement measures of the lifting hydraulic system,and carries out the test verification,which reduces the load of the opening clamp,avoids the risk that the clamp cannot be opened,improves the reliability of the system,and provides guidance for the design of the lifting hydraulic system.
