Novice operation:

由于新手對于高空作業(yè)車不太了解，或者不明白操作方式，容易操作失誤引起故障，甚引起機(jī)械事故;對于這方面的操作人員一定要耐心學(xué)習(xí)，培訓(xùn)合格方可上崗。

Due to beginners not being familiar with high-altitude work vehicles or not understanding their operating methods, it is easy for them to make mistakes and cause malfunctions, and even mechanical accidents; For operators in this field, they must patiently learn and pass the training before taking up their positions.

發(fā)生松動：

Loosening occurs:

高空升降平臺車車新加工裝配的零部件，存在著幾何形狀和配合尺寸的偏差，在使用初期，由于受到?jīng)_擊振動等交變負(fù)荷，以及受熱變形等因素的影響，加上磨損過快等原因，容易使高空作業(yè)車原來緊固的零部件產(chǎn)生松動。

The newly processed and assembled components of the high-altitude lifting platform vehicle have deviations in geometric shape and fitting dimensions. In the early stages of use, due to the influence of alternating loads such as impact and vibration, as well as thermal deformation and other factors, coupled with rapid wear and tear, it is easy to loosen the previously fastened components of the high-altitude working vehicle.

磨損速度快：

Fast wear rate:

由于高空升降平臺車車零部件的加工安裝的因素，其摩擦表面粗糙，接觸的面積較小，承重不均的情況下，就會產(chǎn)生較大的磨損。高空作業(yè)車在運行過程中，零件表面的凹凸部分相互嵌合摩擦，磨落下來的金屬碎屑，又作為磨料，繼續(xù)參與摩擦，更加速了零件配合表面的磨損。因此，磨合期內(nèi)容易造成零部件的磨損，磨損速度快。這時，如果高空作業(yè)車超負(fù)荷作業(yè)，則可能導(dǎo)致零部件的損壞，產(chǎn)生一些故障。

Due to the processing and installation of high-altitude lifting platform vehicle components, their friction surface is rough, the contact area is small, and uneven load-bearing can result in significant wear. During the operation of the high-altitude work vehicle, the concave and convex parts on the surface of the parts are intertwined and rubbed against each other, and the metal debris that falls off is used as abrasive to continue to participate in friction, further accelerating the wear of the mating surface of the parts. Therefore, during the running-in period, it is easy to cause wear and tear on the components, with a fast wear rate. At this point, if the high-altitude work vehicle is overloaded, it may cause damage to the components and cause some malfunctions.

滲漏現(xiàn)象：

Leakage phenomenon:

由于高空升降平臺車車零部件的松動振動和機(jī)器受熱的影響，機(jī)器的密封面以及管接頭等處，會出現(xiàn)滲漏現(xiàn)象;部分鑄造加工等缺陷，在裝配調(diào)試時難以發(fā)現(xiàn)，但由于作業(yè)過程中的振動沖擊作用，這種缺陷就被暴露出來，表現(xiàn)為漏(滲)油(水)。

Due to the loose vibration of the components of the high-altitude lifting platform vehicle and the influence of heat on the machine, leakage may occur at the sealing surface and pipe joints of the machine; Some defects such as casting and processing are difficult to detect during assembly and debugging, but due to the vibration and impact during the operation, these defects are exposed, manifested as oil (water) leakage.

潤滑油使用不當(dāng)：

Improper use of lubricating oil:

高空升降平臺車潤滑保養(yǎng)工作不到位也會引起零部件的配合間隙較小，潤滑油不易在摩擦表面形成均勻的油膜，并且由于裝配等原因，很難保證配合間隙的均勻性，從而降低潤滑效能，造成機(jī)件的早期異常磨損;嚴(yán)重時會造成精密配合的摩擦表面劃傷或咬合現(xiàn)象，導(dǎo)致故障的發(fā)生。

Inadequate lubrication and maintenance of high-altitude lifting platform vehicles can also cause small fitting gaps of components, making it difficult for lubricating oil to form a uniform oil film on the friction surface. Moreover, due to assembly and other reasons, it is difficult to ensure the uniformity of fitting gaps, thereby reducing lubrication efficiency and causing early abnormal wear of the components; In severe cases, it can cause scratches or bite on the friction surface of precision fitting, leading to the occurrence of faults.
