- Q:What kind of documents do you need for driving an excavator?
- It is issued by the Chinese machinery department. It is common in the whole country and has the skills to be reported in our school
- Q:How much are the first pilot pressure and the two pilot pressure of the excavator?!
- The two pilot pressure is usually 10% of the pilot pressure, and the two pilot pressure is controlled by the handle button. A pilot pressure is required with the normal operation of the system is generally about 35kg, two pilot pressure used in special conditions, such as the bucket bucket must use to dig out from the stone soil and the mining stress exceeds the system overflow pressure 345KG system set in a mining buried in the earth stone, then open the two pilot system, the sum of the overflow pressure at that time as one and two times the pilot pressure is 380kg, the working pressure increased to complete this action.
- Q:Excavator card good test?
- Mine is for you, 11OO yuan. It's a little expensive.
- Q:Introduction of excavator
- The hydraulic excavator of the early trial production is the hydraulic technology adopting the airplane and the machine tool. It lacks the hydraulic component suitable for all kinds of working conditions of the excavator, the quality of manufacture is not stable enough, and the supporting parts are not complete. Since 1960s, hydraulic excavators have entered the stage of popularization and vigorous development, and the production and production of excavators and excavators in various countries have been increasing rapidly, and production has soared. In the past 1968-1970 years, hydraulic excavators have accounted for 83% of the total output of excavators, and are now close to 100%. Three 、 the structure of excavator, the common excavator structure includes power device, working device, slewing mechanism, control mechanism, transmission mechanism, walking mechanism and auxiliary facilities, etc.. In appearance, the excavator consists of three parts: the working device, the upper rotating platform and the walking mechanism.
- Q:How about Carter excavator model?
- will be different. In 320D, for example, there are 2.5 and 2.9, two commonly used bucket (small arm) can be selected, bucket in the country with 1 and 1.2 more, and at the same time with heavy bucket, rock bucket, heavy rock bucket is more common. Special conditions can be selected to widen track, guard board, cab protection device, low temperature starting device and so on. Basically, most of the working conditions can be well matched.
- Q:31 excavator factory coding rule is how, it is best to illustrate, thank you!

- Q:The working principle of excavator air conditioner
- All I know is that the compression pump compresses the air in the engine and becomes a cooling air
- Q:How does the excavator cross the ground cable?
- This is not how you simple excavator must first condition excavator track with wire stand in a line up on the side of the excavator digging machine wire; track Caution!
- Q:Which kind of excavator is good?
- Disadvantages: high prices, accessories expensive. (Note: because of the domestic market share is very high, deputy plant parts, so it is cheaper): Japanese brands, Hitachi excavator sales is also very big, general can also assemble. (HITACH) has the advantages of mechanical matching, hydraulic system, flexible action, general value, durability, cost, fuel consumption, power, price 3-5 million cheaper than Komatsu. Disadvantages: not durable, more, after two or three years of serious oil spill, mainly high water temperature or hydraulic system, the No. 20 machine for four missing engine, it is to increase the displacement of the lack of strength reduction, not dare to use, the general price of second-hand car.
- Q:Which country is Carter excavator?
- In fact, Carter is also produced in Japan on the nameplate, there are MADE, IN, JAPAN
