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?yè)P(yáng)機(jī)產(chǎn)生故障的原因除沒(méi)計(jì)、制造、安裝未達(dá)到規(guī)范要求以及設(shè)備長(zhǎng)期使用后零部件的正常磨損外，由于操作管理不當(dāng)引起的故障尤應(yīng)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?yè)P(yáng)機(jī)經(jīng)常出現(xiàn)的故障與機(jī)械傳動(dòng)、電氣傳動(dòng)相比具有多樣性和復(fù)雜性，且與操作管理密切相關(guān)的特點(diǎn)。

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?yè)P(yáng)機(jī)經(jīng)常是幾個(gè)故障同時(shí)出現(xiàn)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(tǒng)中多個(gè)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?yè)P(yáng)機(jī)即使是同一故障，產(chǎn)生的原因也不一樣。特別是現(xiàn)在的船舶液壓設(shè)備都是機(jī)械、液壓、電氣以及微型計(jì)算機(jī)的共同組合體，產(chǎn)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.
