| Fault phenomenon | cause of issue | Remedy |
| Power device vibration | Drive shafts are different or unbalanced | Overhaul adjustment |
| Loose coupling | Overhaul adjustment | |
| Not fixed | Fastening | |
| Rotary reducer overheated | Lack of oil | Add lubricant |
| Rotary reducer impact noise | Incorrect mounting of gears, severe wear of gears or bearings | Adjust the replacement |
| Rotary reducer leak | Damaged seal gasket | replace |
| Axle bad, wear | Repair replacement | |
| Too much lubricant | Remove oil | |
| Slewing ring vibration or noise | Ring or pinion abnormal wear | replace |
| Ball or pad damage | replace | |
| Lack of oil | Refuel | |
| Working arm clevis, working turret, and subframe crack or deformation | Bad material or bad welding | Structure strengthening |
| Improper use, overload and shock | Correct distortion, change | |
| Hydraulic system oil leak | Loose fittings | Fastening |
| Damaged seal | replace | |
| Broken pipe | Welding replacement | |
| Oil pressure does not rise, oil temperature is too high | The fluid level of the tank is too low and the oil filter plug is blocked | Refuel or check |
| Pressure relief valve opening pressure too low | Adjust overflow valve | |
| Pump damage or leakage is serious | Repair or replace | |
| Excessive leakage of pressure and return lines or excessive leakage of hydraulic components | Repair or replacement, proper shutdown cooling | |
| Severe hydraulic system noise | There is air in the pipeline | Repetitive operation exhaust |
| Low oil temperature | Low speed conversion oil | |
| Pipes and components not fixed and fastened | Fastening | |
| Balancing valve failure | Adjustment and overhaul | |
| Filter plug | Cleaning | |
| Falling arm, shrunk arm, excessive oil pressure or vibration | Balance valve signal hole jam | Cleaning balance valve |
| Excessive friction between arms or foreign body | Inspection, adjustment, lubrication | |
| There is air in the cylinder | Repeated movement exhaust | |
| Telescopic arm steel wire length inappropriate | Adjust rope length | |
| The top arm does not reach or shrink | Outrigger lock seal is not good | Overhaul |
| Outrigger failure | Cylinder leakage | Overhaul seals |
1. Introduction of Waste Engine Oil Distillation Plant
Waste Engine Oil Distillation Plant ,is the new technology which can refine the waste engine oil into base oil(which can be made into diesel and gasoline after processed by our catalyst). The oil quality is better than the original normal pressure distillation technology, which show on purity ,transparence, lightness .this technology will do deodorization and destinke process to the raw material oil automatically by "dry type" vacuum pressure distillation method. With the vacuum distillation technology, the distillation temperature is considerably reduced, and the oil output will higher 5%-10% compared with original normal pressure distillation technology. It makes more profits to the enterprise virtually.
2. Raw material which can be used
a. Waste oil .example: waste diesel, waste oil residue etc.
b. tire/rubber oil
c. plastic oil
d. crude oil
e. waste engine oil
f. waste motor oil
g. waste lube oil
h. waste transformer oil
i. underground oil
3. Models of waste engine oil distillation plant
4. Installation: We will be in charge of arranging our engineer to go to your place to guide the installation and train your workers how to operate the waste engine oil distillation plant ,and buyer will be in charge of the food, accommodation and round air tickets.
