When the self loading concrete mixer machine fails, the concrete in in the mixer will also be affected. If the concrete is solidified due to the failure, that will be a great loss. To avoid this situation, the fault of the self loading concrete mixer should be solved in time. How to trouble shoot the self loading mixer quickly?
1. The working principle of tank rotation
Engine power take-off — drive shaft — oil pump — motor — reducer — tank rotation
2. Analysis of the possible reasons
The main reasons for the stop of the mixing tank are as follows:
l Engine failure: the engine cannot start or the power take-off is damaged.
l The bodywork failure: It may be damaged drive shaft, oil pump failure, dirty or insufficient hydraulic oil, motor failure, reducer failure or loose control lever.
3. Find the fault.
When the self loading mixer has some fault, it should be stopped for inspection. We can judge whether there is any abnormal noise from the transmission shaft to the reducer parts through listening and check whether the hydraulic oil tank oil level is too low or the pipeline has a serious oil leakage. Move the the servo rod of the oil pump forwards and backwards to see if the tank body rotates
4. Emergency measures
If the self loading mixer machine can’t be repaired before the concrete is solidified, emergency measures should be taken immediately:
- Connect the "emergency oil pipe" to unload the concrete when the motor and reducer are free of faults.
- If there is something wrong with the motor and reducer, open the manhole cover. If the manhole cover is not under the tank, you need to open a hole at the bottom of the front cone of the tank.
At the same time, pour a large amount of clean water into the feed port, flush the concrete in the tank until no concrete flows out from the tank. A small amount of residual concrete in the tank needs to be manually cleaned and after the complete cleaning, re-weld the cut part to the tank body.
