液壓升降平臺http://www.qdysj.net/彎鉤狀連接方法的接觸電阻很大，通電時不斷發(fā)熱，會使附近的木板逐步干燥、炭化，最后發(fā)生燃燒，引起火災(zāi)。

1、不定期檢查液壓升降平臺接頭狀況，長期運行接頭也會松動，有些接頭在安裝時質(zhì)量是比較好的，但由于熱脹冷縮的原因，或者長期受到振動，會使接頭松動。
Not regularly check hydraulic lifting platform joint condition, long-term operation of joints will loose, some joint in the installation quality is relatively good, but due to thermal expansion and contraction of the reasons, or long-term subject to vibration, loosen the joints.

2、液壓升降平臺http://www.qdysj.net/安裝、修理時接頭未擰緊，當電流通過后可能會發(fā)熱，甚至發(fā)紅、冒煙、冒火、斷線，導(dǎo)線和開關(guān)、用電器通過線線柱連接，因安裝液壓升降平臺的電纜時馬虎，接線柱上不加墊圈，鑼帽也不擰緊，這也會使接觸電阻增大致使導(dǎo)體發(fā)熱熔化，熔珠落在下面的紙板箱上，引起火災(zāi)。
Hydraulic lifting platform installation, repair joints tightening, when through the current may be fever, or redness, smoke, blaze, disconnection, wires and switches, electric appliances by connection wire column, because of the hydraulic lifting platform for the cable installation is careless, wiring column does not add the washer, Gong cap is not tighten, which will make contact resistance increases causing conductor heating melting, the bead falls in the cardboard box below, causing a fire.
