What is a hydraulic excavator?

A hydraulic excavator is a heavy machine, commonly used in construction and rural areas that, as its name suggests, excavates. Thus, she can remove and carry earth, stones, and rubble, among others.

It is also used for moving materials and products, maintaining access roads to crops, and leveling land, among others.

The hydraulic system makes it have a great digging force. This is possible thanks to the existence of oil pumping to the different pistons of the machine, which, in turn, activate another piston together. Thus, they increase the digging force.

But for all this to work, the hydraulic excavator relies on a combination of several components. Among the main ones are:

  • Chassis;
  • mats;
  • Spear;
  • Bucket.

How does hydraulic excavator work?

The hydraulic excavator is a very useful, robust, and efficient machine. But, so that all this can be offered, it has a very complete system and full of components. So the cost of the machine is high. 

Thus, if you already have a hydraulic excavator or intend to purchase one, it is advisable to also get this machine. After all, large investments are positive and reflect positively on the performance of results. 

But, as with any machine, it can also suffer damage or even an accident during work. Thus, to ensure that the necessary support will be given, the ideal is to have insurance for this equipment that has its performance based on hydraulic systems. 

In short, the oil is pumped to the pistons and this creates a great force, which gathers in a piston and allows the machine to work efficiently. 

This ensures greater vitality of the machines, in addition to allowing them to perform their functions quickly. Thus, it optimizes the working time and speeds up the construction. 

Finally, it is worth noting that there are several tools that can be attached to a hydraulic excavator. Among them, for example:

  • cutting blades;
  • Drill bits;
  • Claws for cutting trees;
  • Sledgehammers for demolition;
  • shredders.
