As we all know, excavators are indispensable tools for our engineering construction, especially the reinforced version of the long arm excavator. The construction efficiency is higher. Many people are willing to rent it. Is its operation the same as the original one? Now the manufacturers of the long arm excavator will tell you how to operate the long arm excavator.
Excavator is a relatively large vehicle, to ensure the safety of construction, we must first test, the preparation for construction, especially the smooth degree of the whole vehicle, when testing, it is best to put the top of the well outward 90 degrees, so as to reduce the damage caused by steel bars to the bucket, and then the excavator parallel to the ground, so that the construction is completed. The excavator also has a place to park. And when parking, we must find the right place to park, so that the arm can be fully vertical down, so that the parking is safer.
During construction, attention should be paid to every step of operation. Commanders will command the projects that are generally valued. When the arm is started, it is at a fifteen-degree angle, so that the dredging tools will go underground, extend downward according to the pressure at the bottom, and finally the arm is loaded back with buckets. In order to lift the forearm and bucket rod to make the bucket leave the hole, the main engine chassis is rotated to move the bucket to the other side for dumping, and the bucket is adjusted according to the changes around it.
Special maintenance of telescopic boom
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.
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.
