1、風(fēng)速大于五級時進(jìn)行高空作業(yè)容易使四川液壓升降機(jī)http://www.shyzdq.net/晃動，這樣很容易產(chǎn)生安全事故，再就是四川液壓升降機(jī)支腿沒有按照說明書上打開或沒有安全打開，都會在升降過程中產(chǎn)生影響，造成不穩(wěn)定。
Wind speed greater than five when the height of the Sichuan hydraulic lift is easy to shake, so it is easy to produce a safety accident, and then the Sichuan hydraulic lift is not open on the manual or safe to open, will have an impact on the lifting process, resulting in instability.

2、四川液壓升降機(jī)在工作時，如果達(dá)不到額定電壓，各個部件不能夠正常運行，很容易造成升降不穩(wěn)，縮短液壓升降機(jī)的使用壽命，再就是在工作前要進(jìn)行試機(jī)，空載運行和負(fù)載運行連續(xù)試驗三次以上，方可進(jìn)行操作，以免在工作中發(fā)生故障，運行不穩(wěn)。
Sichuan hydraulic lift in the work, if not up to the rated voltage, the various components are not normal operation, it is easy to cause instability, shorten the service life of the hydraulic lift, and then to test machine, no-load running and load running for more than three times, can be operated, so as to avoid failure in the work, running instability.

3、四川液壓升降機(jī)http://www.shyzdq.net/液壓缸的質(zhì)量變幅很小，不會對升降不穩(wěn)產(chǎn)生影響，忽略不計，液壓升降機(jī)作業(yè)時，用4條支腿作支撐，而所有輪胎都完全離開地面，將升降機(jī)及其載荷看作一個集中載荷固定在作業(yè)臂末端。
Sichuan hydraulic lift hydraulic cylinder of the mass range is very small, will not have an impact on the rise and fall, the hydraulic lift operation, with 4 legs for support, and all the tires are completely left the ground, the lift and its load as a concentrated load at the end of the operating arm.
