Some details of damage to electrical installations and facilities in the case of major excavator failures – practical examples.

Many students, technicians, engineers, practicioners, professors has not opportunity to see large damages of big machines, electrical installations, devices and equipment. This article showing that for all serious and interested people noted above examples from practice.

Imagine the power that is able to smash this big mining machine weight of about 10,000 tons.

Such crashes and this scale are very rare in our country, but they happen quite often in the world. After the crash, the machine goes to waste.

As far as I know, several small and one large, huge rodent excavator happened to us because of a very large “handle” in 2005, where huge masses of altitude tailings separated and almost completely destroyed this ugliness.

However, our experts have been able to completely revitalize this very large machine and to enable it for normal operation, which still works great today. A new and still improved rodent excavator has been obtained.

I received these photos from a colleague of a Sveta Radosavljevic  who was recording and conducting electrical installation from the beginning to the end of the excavator revitalization.

Out of over 200 photographs of the damaged excavator, I have selected here those concerning electrical equipment and installations as well as some characteristic whole machines.

It is interesting that I took this excavator during the revitalization and after the revitalization was completed, because it was “parked” on the assembly site and all over it I pent up and then took over 350 photos of electrical equipment and details without knowing that it was a rubble from the machine . I also later recorded it on the first floor in the “D” field in Zeoke until the mounting plot in all positions of work and movement…
