If there is a fault or problem with the shock absorber of the automatic feeding mixer, first check whether there is oil leakage in the shock absorber, then press the bumper firmly and loosen it. If the mixer has two or three jumps, it means that the shock absorber is good
1. The concrete mixer runs 10 km on the road and stops when the condition is poor. Touch the shock absorber housing with your hand. At this time, you can add appropriate lubricating oil, and then test, if the shell is hot, that is the shock absorber internal lack of oil, should add enough oil; Otherwise, the shock absorber will fail.
2. Remove the vertical shock absorber, connect the upper clamp of the bottom ring vise, and reduce the pulling of the vibrating rod for several times. This time, the resistance should be stable. When pulling up, the resistance should be greater than the resistance. When pressing down, or unstable resistance, it may be that there is no oil baffle inside or the valve parts are damaged. Repair or replace the parts.
3. Press the bumper hard and release it. If the car jumps 2-3 times, the shock absorber works normally.
4. When the concrete mixer runs slowly and brakes suddenly, if the vehicle vibrates seriously, the shock absorber will have problems.
