Excavator arm bucket rod bending deformation, BART repairman direct cutting and welding repair

In front of this excavator, its arm bucket, because of the owner's improper operation, resulting in extremely serious bending, the original owner intends to sell for a new one, but the master here said that it can be repaired, and only 2,000 rupees can make it back to as new. At first, the owner is to try to see the mentality, did not expect after some repairs, actually can be used normally.

In order to ensure the strength and hardness of the welds, they have to carefully grind the steel plates to be reinforced to remove surface rust and impurities, thus making the welds stronger and more reliable.

After cutting the steel plate to the required dimensions, the next operation is to join the plate to the bucket bar. Here the bucket is bent so much that it is welded in place to assist in straightening it. This seems to be simple and rough, in fact, not safe at all, but for the experienced BART this is just a routine operation.

When the bucket is straightened to the right angle, it can be welded immediately afterwards. In order to avoid deviation in the welding process, they will first spot weld a few times to implement the pre-group, and then with the help of a ruler to measure the angle, after confirming that there is no error, and then carry out the full weld fixed.

On the other side, a steel plate is required for reinforcement after cutting the left and right sides of the bucket bars. This bucket is usually made of manganese steel, which is strong, wear-resistant and has good toughness. But its thickness is thin, easy to break when impacted by external forces. Therefore, the same before welding to clean the surface, in order to protect the welding quality and stability.

-Once all the preparations have been carried out, the welding work can be carried out. After welding the end of the bucket, the front part of the bucket is treated, which is also vulnerable to damage. In view of the excavation process, the bucket rod is often subject to impact, extrusion and friction and other conditions, resulting in the front end of the bucket rod wear, rupture and even fracture and other problems.

Therefore, in order to prevent such a situation, generally in the connection of the front end of the bucket bar will be installed with a thicker steel plate, to enhance the overall structural strength of the bucket bar. The role of this thickened steel plate is that when the bucket bar by the external force, can effectively disperse the pressure to prevent excessive concentration of local stress resulting in damage. Moreover, it can also play a role in protecting the internal parts of the bucket bar, reducing the failure and loss caused by external factors.

However, if you want to achieve this effect, just rely on pure welding is absolutely not, but also in its implementation of some patching initiatives. This patching method is the BART masters often use a means of maintenance, they feel that as long as the patches hit a sufficient number of more, then the problem will be solved smoothly. Of course, this is just a joke. In fact, their purpose is quite simple, that is, to make the dipper stronger and more durable.

After all the welding work, followed by outdoor assembly test, this process is quite critical, if the assembly is not in place will have an impact on the subsequent service life. Fortunately, BART masters are extremely skilful, the whole process is extremely smooth. Along the camera can be found, the bucket has been completely restored to the conventional state, and all performance indicators are in line with the requirements.

Going here, this bucket pole, its bending degree is very serious. Here, it is a successful completion of the task. Have to admire this kind of craftsmanship, those from the BART masters, their skills, is really quite impressive.

How many rupees do you think you'll be charged for a repair like this after watching the video?
