How many types of excavators are there? Model 220 is 22-ton bucket capacity of 1.1 cubic meters

Model 240 is 24-ton bucket capacity of 1.2 cubic meters

Model 270 is 27-ton bucket capacity of 1.5 cubic meters

Model 300 is 30-ton bucket capacity of 1.6 cubic meters

Model 400 is 40-ton bucket capacity of 0.65 cubic meters

The model is 400 is 40 tons of bucket capacity in 1.9 cubic meters

The model is 250 is 45 tons of bucket capacity in 2.1 cubic meters

The above generally refers to the natural excavation of the pile loaded with a variety of brands of excavator models are not the same

PC200-8, PC is on behalf of Komatsu Excavator Series 200 is on behalf of the 20-ton, -8 on behalf of the push of new The generation.

Carter 306, 3 is on behalf of the Carter excavator series 06 is on behalf of the 6-ton class, pushing the new generation is represented by ABCD.

Maintenance

The purpose of regular maintenance on excavators is to: reduce machine breakdowns, extend the life of the machine, shorten the machine's downtime, improve efficiency, and reduce operating costs? [4]?

Just by managing fuel, lubricants, water and air, you can reduce breakdowns by 70%. In fact, about 70% of breakdowns are due to mismanagement.

Daily inspection

Visual inspection: a visual inspection should be carried out before starting the locomotive. Thoroughly check the surroundings and underside of the locomotive in the following order:

1. For oil, fuel and coolant leaks.

2. For loose bolts and nuts.

3. Any broken wires, shorts and loose battery connectors in the electrical wiring.

4, whether there is oil.

5. Whether there is any accumulation of folk.

Daily maintenance precautions

Daily inspection work is to ensure that the hydraulic excavator can be maintained for a long time an important part of the efficient operation, especially for the individual, do a good job of the usual daily inspection work can effectively reduce the cost of maintenance.

First of all, the first around the mechanical turn around two laps to check the appearance and mechanical chassis have no abnormalities, as well as the slewing bearing whether there is grease flow, and then check the deceleration braking device as well as crawler bolts and fasteners, the tightening of tightening, the change of timely replacement, if it is a wheeled excavator need to check whether the tires are abnormal, as well as the stability of the air pressure.

Check whether the excavator bucket teeth have greater wear, it is understood that the wear of the bucket teeth will significantly increase the resistance of the construction process, will seriously affect the efficiency of the work, increase the degree of wear and tear of equipment parts.

View the bucket rod and the oil cylinder whether there are cracks or oil leakage phenomenon. Check the battery electrolyte to avoid being below the low level line.

The air filter is an important part that prevents large amounts of dusty air from entering the excavator and should be checked and cleaned frequently.

Check fuel, lubricating oil, hydraulic oil, coolant, etc., often, whether it needs to be added, and it is best to choose the fluid according to the instructions and keep it clean.

Check after starting

1, the hooter and all the gauges are intact.

2, the starting state of the engine, noise and exhaust gas color.

3, for oil, fuel and coolant leaks.

Fuel management

To use different grades of diesel fuel according to different ambient temperatures (see Table 1); diesel fuel can not be mixed with impurities, ash and water, otherwise it will make the fuel pump premature wear; poor-quality fuel paraffin and sulfur content is high, which will cause damage to the engine; fuel tank should be full of fuel after daily operations to prevent water droplets on the inside wall of the fuel tank; open the drain valve at the bottom of the fuel tank before daily operations. Open the drain valve at the bottom of the fuel tank before daily operation to drain the water; After the engine runs out of fuel or the cartridge is replaced, air must be drained from the circuit.

Minimum ambient temperature 0℃ -10℃ -20℃ -30℃
