As a special tool for high-altitude operation, the lifting platform has the characteristics of high efficiency and convenient use. It sometimes encounters common faults in the whole work process. In order to better avoid delaying the application of everyone, we should grasp some maintenance knowledge. The following hydraulic freight elevator wholesale manufacturers will briefly talk about the common faults.

①升降平台上升不上设置定相对高度，这样的事情要查验机油箱内的齿轮油是不是做到规范容积，查验机油箱是不是渗油，假如齿轮油不足，请加上32#齿轮油，这类在五金店都是会有。

① If the lifting platform cannot be raised to a fixed relative height, it is necessary to check whether the gear oil in the oil tank meets the standard volume and whether the oil in the oil tank leaks. If the gear oil is insufficient, please add 32\.

②升降平台存有静电感应，造成不升高或是不降低，是由于在布线的过程中没有电线接头，使液压升降平台带静电感应造成电源箱失效，可以用金属产品碰地就可以。

② The lifting platform has electrostatic induction, which causes no rise or fall. The reason is that there is no wire connector in the wiring process, which makes the hydraulic lifting platform with electrostatic induction and causes the power box to fail. You can touch the ground with metal products.

③升降平台只有升高，不可以降低：查验真空电磁阀显示灯是不是亮，按电源箱上的降低键，假如真空电磁阀上灯不闪，则查验真空电磁阀两条线是不是短路或是松垮。

③ The lifting platform can only be raised but not lowered: check whether the vacuum solenoid valve display light is on, press the lower button on the power box, and if the vacuum solenoid valve light does not flash, check whether the two lines of the vacuum solenoid valve are short circuited or loose.

④升降平台在调节的情况下左右发抖，颤动：查验滑轨内是不是有小颗粒，废弃物，滑轨内机油是不是也有，没有请立即加上不然，长期损坏造成液压升降平台卡死毁坏。

④ The lifting platform trembles and vibrates left and right under adjustment: check whether there are small particles, wastes and oil in the slide rail. If not, please add it immediately. Otherwise, the hydraulic lifting platform will be stuck and damaged due to long-term damage.

⑤即使阴雨气温不调整，请检查电源箱控制面板是否湿冷：请用吹风机烘干。

⑤ Even if the temperature is not adjusted in rainy days, please check whether the control panel of the power box is wet and cold: Please dry it with a hair dryer.

⑥调节在起步时能一切正常升高，调节到一半时不可以调节：一种是启动电容器毁坏，另一种是液压油滤芯剩余油不够。

⑥ The adjustment can rise normally at the start, but cannot be adjusted at half of the adjustment: one is that the starting capacitor is damaged, and the other is that the remaining oil in the hydraulic oil filter element is insufficient.

⑦假如输油管渗油，查验标准接口是不是毁坏，查验O型液压密封件是不是毁坏，拆换液压密封件或是是总体拆换标准接口。

⑦ If the oil delivery pipe leaks, check whether the standard interface is damaged, check whether the O-type hydraulic seal is damaged, and replace the hydraulic seal or the standard interface as a whole.

⑧升降平台调节摇架，调节自升：查验真空电磁阀内是不是有废弃物，如车用汽油清理或是用气动枪刮走就可以；

⑧ Adjust the cradle of the lifting platform and adjust the jack up: check whether there is any waste in the vacuum solenoid valve, such as cleaning with gasoline or scraping away with a pneumatic gun;

⑨不可以升高，只有降低：查验行程安排是不是抓牢，看左右间距是否有5mm行程安排，康佳四个行程安排后盖板上的螺丝，将行程安排内扭簧校准就可以。

⑨ Do not raise, only lower: check whether the travel arrangement is firmly grasped, and see whether there is a 5mm travel arrangement between the left and right. The screws on the rear cover plate of Konka's four travel arrangements can be aligned with the torsion spring in the travel arrangement.

⑩升降平台指示灯没亮：检查墙上的电源插座是否有开关电源，插板和电线插头是否短路。如果超过100米，请使用2.5的电源插头进行调整。

⑩ The indicator light of the lifting platform is not on: check whether the power socket on the wall has switching power supply, and whether the plug board and wire plug are short circuited. If it is more than 100 meters, please use a 2.5 square meter power plug for adjustment.
