Long arm excavator is a kind of earthmoving machinery which uses shovel to excavate materials above or below the surface of the carrier and loads them into transport vehicles or unloads them to the stockyard. It has become one of the most important construction machinery in engineering construction. In use, reasonable maintenance is an effective way to extend the service life of the machine.
Daily inspection work is an important link to ensure that hydraulic excavators can maintain efficient operation for a long time. Especially for individual households, daily inspection work can effectively reduce maintenance costs.
First, check the appearance of the mechanical chassis and whether there is any abnormality, as well as whether there is grease outflow from the slewing support. Then check the retarder brake device and the bolt fasteners of the caterpillar. The tightening and timely replacement of the tightening, if it is a wheel excavator, it is necessary to check whether the tire is abnormal, as well as the air pressure. Stability.
It is known that the wear of bucket teeth will greatly increase the resistance in the construction process, will seriously affect the work efficiency and increase the wear degree of equipment components.
Check whether there are cracks or oil leakage in bucket and cylinder. Check the battery electrolyte to avoid being below the low level.
Air filter is an important part to prevent a large amount of dusty air from entering excavator. It should be checked and cleaned frequently.
Check the fuel oil, lubricant, hydraulic oil, coolant, etc. regularly to see if they need to be added, and it is best to select the oil according to the instructions and keep it clean.
Advantages and features of telescopic boom
The advantages of the telescopic arm are that it has a large bearing capacity in a small range, a long working distance and a high working height under allowable loads. Telescopic boom is mostly used in construction vehicles or other transport vehicles. The telescopic arm excavator is mainly aimed at the excavator affected by its inherent structure. The telescopic arm or bucket rod is generally limited, which causes the excavation depth to be affected correspondingly. It is difficult to meet the requirements of the construction site.
The characteristics of telescopic boom are:
1, the distance between effective operation and operation is high. The telescopic arm structure can achieve a long distance, and the amplitude of the arm can achieve a higher operating height, which is incomparable with traditional excavators.
2, we can directly load and unload cargo through some obstacles. The telescopic boom device can be used for loading and unloading across ditches, steps, doors and windows. Because of the negative angle of variation, the ditches on the stopping surface can also be cleared, repaired and leveled, so it is more suitable for use in the field.
3, it has better job safety performance. The telescopic arm excavator has the function of load telescoping. When stacking on uneven pavement, it can stop far away from the stacking point, open the stable leg, and complete the loading and unloading of cargo by telescoping and amplitude changing action. It is also convenient to clean and dismantle the furnace in the steelmaking workshop.
4, it is easy to replace multiple genera and expand the scope of operation.
