The insides of excavators are very important to make them able to dig and move things. Excavators are large machines that resemble dinosaurs, with long arms and big claws. In these powerful machines, there are many different working parts that must work together to make it all happen. Let’s take a closer look at these parts and what they do for an excavator.
The workability of the excavator depends upon the engine. In the same way that we require food for energy, the engine is what provides the energy to the excavator so it can move and perform work. The engine acts a bit like the heart of the excavator, pumping power through to all the other parts which means it must work efficiently otherwise the other parts will cease to operate at full capacity. But without the engine, the excavator would be completely immobilized, unable to move or dig.
Then there’s the hydraulic system, which is akin to the muscles and nerves of the excavator. It’s good for the arms and bucket to get some action in. Fluids are used in the hydraulic system to create force that makes the parts of the excavator move. This mechanism allows the excavator to lift heavy objects and transport them without difficulty. The excavator would hardly be able to function without the hydraulic system.
The excatavator’s tracks or wheels are what allow the excavator to travel. Just as we use our legs to walk, those tracks or wheels support an excavator as it moves from one place to another. They are similar to the feet of the excavator that enable it to move across uneven terrain. They also stabilize the excavator so it does not tip over while digging. No tracks, no wheels and the excavator would be stranded in the same place.
With the boom and the bucket, an excavator can reach and lift items. The boom is sort of like the long arm of the excavator, going out and grabbing things. It’s like a big claw that picks up dirt and rocks by the load full and then moves them. Combined, they allow the excavator to reach high places and lift heavy objects. Without them, the excavator couldn’t dig, or move anything at all.
The controls are what allow the operator to manipulate the excavator. They are to the person operating the machine what the hands are to the rest of the population for picking stuff up. Controls are the brain of the excavator — guiding the operator through sensitive movements. Without the controls, the excavator couldn’t take commands or do its job properly.
