The fault of the hydraulic hoist often appear: fault action (such as starting not normal, actuator speed too slow or not under load action, actuator velocity decreased etc.); pressure of fault (such as pressure is not up to the requirements, pressure instability or pressure regulator failure, pressure impact); noise and vibration; temperature high oil pollution.

液壓卷揚機產生故障的原因除沒計、制造、安裝未達到規范要求以及設備長期使用后零部件的正常磨損外，由于操作管理不當引起的故障尤應注意。

Hydraulic hoist failure did not design, manufacturing, installation and removal does not meet the specification requirements and equipment after long-term use parts of the normal wear and tear, because the fault caused by improper operation management, more attention should be paid to.

液壓卷揚機經常出現的故障與機械傳動、電氣傳動相比具有多樣性和復雜性，且與操作管理密切相關的特點。

Compared with the hydraulic winch frequent faults and mechanical transmission, electrical transmission has the diversity and complexity of operation and management, and related.

液壓卷揚機經常是幾個故障同時出現并交織在一起，這些故障有的是由某一液壓元件失靈引起，有的則是系統中多個液壓元件的綜合因素造成。

The hydraulic winch is often several faults occur at the same time and intertwined, these faults are caused by a hydraulic component failure, some comprehensive factors of multiple hydraulic component in the system.

液壓卷揚機即使是同一故障，產生的原因也不一樣。特別是現在的船舶液壓設備都是機械、液壓、電氣以及微型計算機的共同組合體，產生故障的原因更是多方面的。同一原因，也可能引起不同的故障。

Hydraulic hoist even for the same fault, the causes are not the same. Especially the ship hydraulic equipment are now common combination of mechanical, hydraulic, electrical and computer, the reasons of the failures even more aspects. The same reason, may also cause different failure.
