In the field of construction machinery, excavator, as a multifunctional and high-efficiency construction equipment, has become a powerful assistant for all kinds of engineering construction. However, many cold knowledge about excavators may not be well known to the public. Today, we will reveal the mysteries of the excavator.

Ⅰ.Excavator to dig the cable, people will not be electrocuted

In engineering construction, excavators may sometimes accidentally dig underground cables. Surprisingly, however, the operator is not electrocuted by this. The reason is that the excavator is an equipotential body. When the arm of the excavator touches the high-voltage line, the whole car will be charged, and the operator will also be with high voltage. But the point is that, because the potential inside the car is equal, so although the operator has a voltage, but can not form a current, thereby avoiding the occurrence of electric shock accident. This principle provides a strong guarantee for the safety in engineering construction.

Ⅱ.Dual-arm excavator, niche and efficient

When it comes to excavators, people often associate them with its iconic single arm. However, in fact, there is also a small number of high-efficiency devices, such as dual-arm excavators. Dual-arm excavators are mainly used for intermediate processing of industrial waste and rubble treatment operations in affected areas. Its unique dual-arm design makes it excellent in handling complex terrain and heavy lifting. However, due to its advantages in segmented fields and difficulty in operation, dual-arm excavators are not widely used at present, and only play an important role in niche fields.

Ⅲ.When demolishing a building, how does the excavator climb to the roof?

In the demolition operation, excavators often need to climb to the roof of the building for operation. So how did these behemoths get to the top of the building? Originally, excavators for building demolition usually choose small excavators and lift them onto the roof through large cranes. Excavators then work from the top of the building, removing the building floor by floor. This unique operation method not only improves the efficiency of building demolition, but also ensures the safety in the construction process.

To sum up, as an important equipment in engineering construction, excavators contain many little-known technical details behind them. By understanding these cold knowledge, we can have a deeper understanding of the excavator and better play its role in practical applications. In the future, with the continuous progress and innovation of technology, excavators are expected to show their unique value and charm in more fields.
