1. I don't know whether you are a liar or not, but I'll give you some advice. First of all, you should have the right to use it legally. Don't say it's yours. You should have written evidence. Don't waste your time
2. The correct operation steps and methods are necessary to operate the excavator. The correct operation method is not only safe, but also beneficial to the excavator itself. The correct operation method can extend the life of the excavator. So the following by Changzhou Black King Kong construction machinery to introce the correct operation of the excavator
1. When excavating, the surface layer should be taken first, while the lower layer should not be excavated to the bottom at one time (especially the excavation of deep ditch is particularly important). If the width of the ditch is larger than the bucket width, the two sides should be excavated first, and then the middle should be excavated
2. When digging a straight ditch, the excavator should retreat in a straight line, and the movement of the bucket can be adjusted according to the track marks left by the retreat, which is mainly based on the starting point of excavation; The excavation of curved ditch is to follow the curve or cooperate with rolling back when retreating
3. The excavated soil should be placed one meter away from the edge of the ditch in turn, and it should be placed with the ditch type
4. Make sure there are no obstacles around the excavator
5
6. Confirm that there is no alarm on the instrument
7. Turn the shut-off valve to on
8. Operate the excavator: pedal control the whole vehicle forward and backward; The front and back of the right handle controls the lowering and raising of the boom, and the left and right of the right handle controls the retraction and release of the bucket; The front and back of the left handle controls the rotation, and the left and right of the left handle controls the lifting and lowering of the stick
there are three main excavation methods:
1. Riding type: mainly in the open area, the excavator is parked in the middle of the ditch to be excavated, and the bucket is g between the two crawlers
2. Along side type: it means that when the site is narrow, like a clean water channel, the bucket only digs along one side of the track line
3. Facing type: it is mainly aimed at the excavation of highway culvert ditch, which means that the excavator is parked at 90 degrees to the ditch edge (it should be noted that when the ditch is deep, the bucket cylinder may encounter the ditch edge). For the excavation of well shaped ditch, attention should be paid to the control of sequence, and the trimming technique of 90 degrees should be used when excavating the joint of ditch and ditch.

3. It can dig 70 cm on ordinary land. Ordinary excavators can dig 50 cm, because Carter excavators are powerful
4. China's General Carter is a joint venture between China and the United States. Its origin is in Xuzhou. Its fuel consumption is slightly higher than that of similar cars, but its strength is sufficient. It is generally used for doing stone work in mines. When it comes out, it is generally used to buy special rock buckets. Its most basic characteristics are high fuel consumption and powerful~~~~~~~~~~~
5. The main working environment of the gun machine is very bad. The seal of the gun machine is not very good. In a few days, there will be oil leakage, and the st can run into the hydraulic system, which causes great pollution to the hydraulic system. The impact force of the gun machine is large, and the valve core inside the gun machine is seriously worn. After a long time, you can see a lot of obvious iron filings in the oil return filter element of the hydraulic oil tank. It's coarse... 2625
6. Basically, the monthly price of each place is different now. The reference price is 33000 Carter D, and the other 30000
7. There are many brands of excavators, such as Carter, Komatsu, Hitachi, Shengang, Hyundai, Daewoo excavators,
Kato excavators, and so on. Although there are so many excavator brands, if you buy excavators, so many brands, buy first-class brands: Carter. Caterpillar, one of the world's top 500 enterprises and a giant in the construction machinery instry, has the strongest mining power, high cost performance and rability. The disadvantage is that the previous A-type, B-type and C-type engines consume relatively high oil, but as the saying goes, they eat well, but now the new-type D-type engine uses EFI technology and computer board control to inject oil evenly. Now the new-type D-type engine also saves fuel; The resial value of Carter excavator will be quite high in the future,
as soon as you inquire about the second-hand market, you will know
second rate brands: Komatsu, Liebherr, Volvo, etc. Although Komatsu's quality is not as good as Carter's, it is still better than a
brand, with obvious shortcomings and small strength, so it is not suitable for stonework. Liebherr is rable and stable,
it has a good quality, but the price is high, the brand is not very loud, the market share is poor, and the parts are hard to find; Volvo used to be very good,
relatively fuel-efficient, but after the acquisition of Samsung, the quality is getting worse and worse, the parts are very difficult to find, the mining power is not good,
and the later maintenance cost is quite high. It's not recommended that you use this brand. The advantage is that it's well-known and nothing else
third rate brands: Japanese brands, such as Shengang, Hitachi, Sumitomo and Kato. The quality of these machines is acceptable, the oil consumption is generally not high, but the stability is relatively poor
four brands: Korean, such as Doosan and Hyundai. The price is low, which is suitable for newcomers who have just entered the
instry of construction machinery. Although the stability is relatively poor, there is still a big difference compared with domestic machines. The main selling point is the low price
fifth rate brand: domestic machine< In fact, Carter and Komatsu have always been competitors in China. Carter must be the leader of the construction machinery instry in the world. Komatsu is trying to catch up and challenge Carter's position as the leader
Carter excavator is not easy to break down, but its agents in China are a bit big, which is not as good as Komatsu
the advantages are: rable, powerful and cost-effective
Komatsu has less strength, less stability and low rability. The advantage is that the dry earth work is fast.

8. The digging force of cat excavator is not the largest. The pressure is almost the same. It's just that the digging stick of Carter machine is relatively short, so the relative strength will be slightly larger. For example, compared with other 350 excavators, Carter 336d excavators are of the same level. But the length of the digging stick is very different
4000 tons, a little heavy workload. More than 330 machines are recommended. That is, Carter 336 or above or other Japanese models 330 or above. The efficiency is quite high. The Carter 360 machine you said is a 600 class super large excavator with a weight of 60 tons. This is quite a cow. 4000 tons. It's too small. A 60 ton excavator with a bucket of at least 2.8 cubic meters, at least about 5 tons. If you calculate, it will be 4000 tons in a few buckets. It's easy to deal with. 330 or above is enough. But your title doesn't correspond to your content. Is it more than 4000 cubic meters or more than 4000 tons. If it's more than 4000 cubic meters, 10 hours a day. It's too much work to do with excavators. We really need to consider excavators of more than 60 tons
there is nothing to reinforce the bucket teeth, which is troublesome and ineffective. Change it when you use it,. But the bucket should be reinforced. You can go to the local professional welding bucket shop. There will be more professional suggestions.

9. Excavator is the main construction machinery in earthwork engineering, which is widely used in construction, road construction, water conservancy, open-pit mining and national defense engineering. If the excavator is not maintained in time, there may be various faults. According to my own practical experience, I analyze the common faults of the excavator as follows, for reference only< Br > 1. Excavator can not start or is difficult to start < br > 1.1 electrical system fault < br > 1.1.1 the battery is insufficient. In this case, the battery should be charged in time, the liquid level of the battery should be checked, and the electrolyte should be supplemented to the specified height in time. If it is found that the battery is aging and poorly charged, it should be replaced, and at the same time, pay attention to the daily maintenance of the battery, and it is not often in the state of power loss< Br > 1.1.2 repair or replace the starter< Br > 1.1.3 generator fault repair or replacement< Br > 1.1.4 line fault check and repair the line< Br > 1.2 engine oil circuit fault < br > 1.2.1 air resistance of low pressure oil circuit < br > under the suction action of fuel pump or injection pump, the fuel is sent from the fuel tank to the high pressure pump through the low pressure oil circuit. If the low pressure oil circuit is not tightly closed, or the oil level in the fuel tank is too low, and the vehicle is inclined to park and drive, air will take the opportunity to enter the oil circuit; If the temperature is high and the fuel evaporates, it will form a gas lock in the low-pressure oil circuit, which will cause the engine to work unsteadily, automatically shut down or fail to start< Br > 1.2.2 blockage of oil circuit < br > the common parts of blockage of oil circuit mainly include oil suction pipe, filter screen, diesel filter, oil tank cap vent, etc. The main problems that cause the blockage of the oil circuit are the injection of substandard diesel or the mixing of impurities in the refueling process. The key of prevention is to ensure the diesel oil cleaning and oil circuit sealing, carry out regular maintenance on the oil circuit, strengthen the cleaning and maintenance of the diesel oil filter, clean or replace the filter element in time, clean the oil tank in time according to the working environment conditions, and thoroughly remove the oil sludge and moisture at the bottom of the oil tank< Br > 1.2.3 fault of fuel injection pump < br > the plunger and outlet valve of fuel injection pump are seriously worn, which makes it difficult to start the engine. At this time, the plunger and oil outlet valve couple should be replaced in time< Br > 2. The excavator is not working well < br > 2.1 the engine power is sufficient and the operation is normal, while the excavator is slow and the digging is weak< Br > 2.1.1 the hydraulic pumps of excavators are mostly variable piston pumps. After working for a certain period of time, the internal parts of the pump will inevitably be worn, causing internal leakage, and the data of various parameters are not coordinated, resulting in insufficient flow, high oil temperature, slow speed, unable to establish high pressure, so the action is slow and weak. For this kind of problem, it is necessary to remove the hydraulic pump for data measurement, confirm the problem, replace the spare parts that can not be used, or repair the spare parts that can be used. After reassembly, it is necessary to adjust the bench and match the parameters of each circuit (pressure, flow, power and variable)< There are main safety valve, secondary valve, relief valve, oil replenishing valve and so on on. If the pressure set by these valves does not reach the standard pressure, the excavation will be unable. In addition, if the gap between the valve stem and the valve hole is too large e to wear, the return of the valve stem is not complete, and the reversing is not in place, a large number of internal leakage will result in insufficient flow and slow speed. For such problems, the multi-channel distribution valve should be removed and sent to the test bench for debugging. The pressure of all valves should be reset to the standard pressure, and the clearance between the valve stem and the valve hole should be eliminated< Br > 2.1.3 hydraulic pumps on imported excavators are equipped with pilot gear pump, which is mainly involved in the variable of hydraulic pump and as pilot oil, open the valve stem of multi-channel distribution valve to make it change direction. If the gear pump is too worn to establish a certain pressure or the setting of the safety valve on the gear pump can not reach a certain pressure, the hydraulic pump will always be in a low flow state, and the valve stem can not be completely reversed, resulting in insufficient flow, slow action, insufficient pressure and weak excavation. For this kind of problem, just change the pilot gear pump or reset the pilot relief valve< Br > 2.2 when the engine is cold, everything is normal. When the engine is hot, it moves slowly and the digging is weak. Such problems show that the internal parts of the hydraulic pump are seriously worn, so it is necessary to replace the vulnerable parts in the pump, reassemble and adjust the test bench for calibration and debugging< Br > another main reason for the slow and powerless operation of the whole excavator is the deterioration of the hydraulic oil. Therefore, it is necessary to monitor the quality of the hydraulic oil (viscosity, fluidity and the presence of suspended solids, etc.) and replace the hydraulic oil that meets the requirements on time, which can largely avoid such failures< Br > 3. Excavator running deviation < br > 3.1 hydraulic pump failure < br > in general, excavators use double pump, and running deviation is usually caused by one pump failure. The simplest way to judge is to change the two high-pressure oil outlet pipes of hydraulic pump, if the original slow one becomes faster and the original fast one becomes slower, it is proved that one pump has failure. Troubleshooting: remove the hydraulic pump, replace the damaged parts, and then go to the test bench for debugging< Br > 3.2 the oil leakage of the safety valve of the travel motor < br > the oil leakage of the safety valve will cause the pressure in the system to be too low, so that the speed of the travel motor is not enough, resulting in travel deviation. The elimination method is: replace the damaged travel motor safety valve; When judging, the left and right traveling motors can be safely exchanged to see if they are deflected when walking in the opposite direction< Br > 3.3 the digging machine deviates to one side < br > if the spring in the walking main valve becomes soft or broken, or the valve core is stuck, the oil pressure may decrease and the walking deviation may occur. During the inspection, the pressure of the main valve oil circuit should be measured, and the normal value is 32.5mpa. If the main travel valve is damaged, it should be replaced or repaired< Br > through the above analysis, we can see that 80% of excavator failures are caused by untimely maintenance or improper operation. Therefore, we should do a good job in excavator maintenance, improve the technical level of operators, rece the occurrence of failures, and ensure the smooth progress of engineering construction.
10. Carter's excavator is still good. Its power and rotation ability are quite good, but there are two shortcomings in the United States.
first, Carter's unique engine must be repaired by Carter's service personnel point to point.
Second, the fuel consumption is relatively high. It can be said that Carter is the one with the highest fuel consumption at present. There are some shortcomings in the United States and China
