Excavators are big pieces of equipment that are used for a wide range of building and tearing down jobs. They have a lot of different parts, and each one is necessary for the machine to work.
This piece will talk about the main parts of an excavator and what they do. I will also give you some advice on how to keep your digger in good shape.
Engine
The engine is the powerful part of the excavator that makes all of its tasks possible. In most excavators, the engine in the back is a diesel power plant. A torque converter moves the power from the engine to the hydraulic system.
Hydraulic System
The hydraulic system makes it possible for the digger to move. It has a pump, pistons, and valves. The hydraulic power that moves the boom, arm, and bucket of the excavator comes from the pump. The excavator’s parts are moved by the cylinders, which are called actuators. The valves decide how much hydraulic fluid gets to the cylinders.
Boom
The long arm that sticks out from the excavator’s body is called the boom. It moves the bucket and lifts it. The boom is usually made of steel, and hydraulic pistons hold it up.
Arm
The arm is connected to the boom and moves the bucket forward and backward. The arm is also made of steel, and hydraulic pistons hold it up.
Bucket
The tool that is used to dig, scoop, and move stuff is the bucket. It’s connected to the arm’s end. The teeth or claws on the bucket help it hold the stuff. The bucket is usually made of steel.
Cab
The cab is the area where the operator sits and is on top of the digger. It gives the user a good view of the work area and the controls that make the machine work. A roll bar and a seatbelt are also built into the cab for safety.
ROPS
ROPS stands for “Rollover Protective Structure.” It is a safety device that helps keep the driver safe in case of a rollover. A frame called the ROPS is built around the cab and is meant to hold up in the event of a rollover.
Counterweight
At the back of the digger, the counterweight helps keep the weight of the boom and bucket even. Most counterweights are made of steel and are connected to the chassis of the excavator.
Track System
The digger can move because of the track system. It has idlers, tracks, and sprockets. These are the metal loops that run along the bottom of the digger. They are called tracks. Spurs are the wheels that the tracks move on. Idlers are the rollers that hold the tracks in place.
Other Important Parts
It also has the following other important parts:
Hydraulic pump: The hydraulic pump is what makes the pressure that the hydraulic system of the digger needs to work.
- Hydraulic cylinders: The boom, arm, and bucket of a digger are moved by hydraulic cylinders.
Major control valve: The main control valve is in charge of the hydraulic system of the digger. It tells the hydraulic fluid how to move to the different motors and cylinders.
The excavator moves forward and backward with the help of the trip motor.
Track adjusters: The track adjusters make the track chains tighter.
Sticky pads: These are on the bottom of the tracks and help the wheels stay in place.
What parts a digger has will depend on the type and brand of machine it is. On the other hand, all excavators have the same main parts.
