With the rapid development of China's industry, the increasing number of factories, production and manufacturing continue to expand, the demand for aerial work equipment is also increasing, for users, a huge aerial work vehicle seems very mysterious, no matter what a small part of the problem will make you helpless, in the face of the frequent use of these aerial work equipment, Naturally, there are breakdowns and maintenance problems. Then, according to some problems often encountered in the use of the lifting platform, Xiaobian here to the majority of friends to analyze, so that you can find the cause of the failure and solutions in time!

        01When the lifting platform is in use, the indicator light is not on

Analysis of the cause: the power supply is blocked, the fuse is blown

Troubleshooting method: Check the power jack and replace the fuse

       02Encounter lifting platform does not rise

Analysis reason: motor reversal; The unloading valve is not closed; The hydraulic oil is not clean, there are iron filings, debris or other debris, so that the check valve in the manual oil pump is not completely closed; Or the hydraulic oil freezes

Elimination method: power line replacement phase line; Close the unloading valve; Filter or replace hydraulic oil, thoroughly clean the inside of the hydraulic system; Replace with antifreeze hydraulic fluid

       03Automatic descent of the lifting platform

The reasons are as follows: 1. Hand pump unloading valve is not completely closed; 2. Oil leakage of hydraulic system; 3. There are foreign bodies in the support valve; 4. The valve core of the support valve is worn

Troubleshooting method: 1. Close the unloading valve again; 2. Find out the oil leak and repair it; 3. Clean the support valve; 4. Replace the support valve

       04When the lifting platform does not fall

The reasons are as follows: 1. The unloading valve of the hand pump is not fully opened; 2. The cutting fork is stuck, or the roller groove has foreign bodies; 3. Freeze hydraulic oil

Troubleshooting method: 1. Open the hand pump unloading valve; 2. Repair the stuck place and remove foreign matter in the roller groove; 3. Replace the hydraulic oil
