The bucket with model 160, i.e. 16 tons, has a capacity of about 0.65 cubic meters.

Model 200, that is, the capacity of a 20-ton barrel is about 0.8 cubic meters.

Model 220 is a 22-ton bucket with a capacity of about 1. 1 m3.

Model 240 is a 24-ton bucket with a capacity of about 1.2 cubic meter.

Model 270 is a 27-ton bucket with a capacity of about 1.5 cubic meters.

The model is 300 or 30 tons, and the bucket capacity is about 1.6 cubic meters.

The model is 400 or 40 tons, and the bucket capacity is about 1.9 cubic meters.

Model 250 is a 45-ton bucket with a capacity of about 2. 1 m3.

The above generally refers to natural excavation and stacking, and the models of excavators of different brands are different.

PC200-8, PC stands for Komatsu excavator series 200, representing 20 tons, and -8 stands for innovation.

Carter 306,3 stands for Carter excavator series 06 stands for 6 tons, and the new algebra is represented by ABCD.

maintain

The purpose of regular maintenance of excavators is to reduce machine failures, prolong machine service life, shorten machine downtime, improve work efficiency and reduce operating costs? [4]? .

As long as the fuel, lubricating oil, water and air are well managed, 70% of failures can be reduced. In fact, about 70% of failures are caused by poor management.

Check regularly.

Visual inspection: Visual inspection shall be carried out in front of the starter. Thoroughly inspect the surrounding environment and the bottom of the locomotive in the following order:

1, whether there is oil, fuel and coolant leakage.

2. Whether the bolts and nuts are loose.

3. Whether there is disconnection, short circuit and loose battery connector in the electrical circuit.

4. Whether there is oil pollution.

5. Is there any accumulation of contacts?

Matters needing attention in daily maintenance

Daily inspection is an important link to ensure the long-term and efficient operation of hydraulic excavators, especially for self-employed, doing daily inspection can effectively reduce maintenance costs.

Turn the machine twice first, and check whether there is any abnormality in the appearance and chassis of the machine, and whether there is oil flowing out of the slewing support. Then, check the bolts and fasteners of the retarder and the crawler. If it is a wheeled excavator, it is necessary to check whether the tires are abnormal and whether the air pressure is stable.

Check whether the bucket teeth of the excavator are seriously worn. It is understood that the wear of bucket teeth will greatly increase the resistance in the construction process, seriously affect the work efficiency and increase the wear of equipment parts.

Check the stick and cylinder for cracks or oil leakage. Check the battery electrolyte to avoid falling below the low level.

The air filter is an important part to prevent a large amount of dusty air from entering the excavator, so it should be checked and cleaned frequently.

Check fuel, lubricating oil, hydraulic oil, coolant, etc. frequently. Need to add, and it is best to choose oil according to the requirements of the manual and keep it clean.

Post-startup inspection

1, the horn and all instruments are in good condition.

2. Engine starting state, noise and tail gas color.

3, whether there is oil, fuel and coolant leakage.

Fuel management

Choose different brands of diesel oil according to different ambient temperatures (see table1); Diesel oil cannot be mixed with impurities, lime soil and water, otherwise it will make the fuel pump wear prematurely; The high content of paraffin and sulfur in inferior fuel will damage the engine; After daily operation, the oil tank should be filled with oil to prevent water droplets from forming on the inner wall of the oil tank; Open the drain valve at the bottom of the oil tank to drain water before daily operation; After the engine runs out of fuel or the filter element is replaced, the air in the road must be exhausted.

The lowest ambient temperature is 0℃-10℃ -20℃ -30℃

Diesel brand 0#-10# -20# -35#
