More than one emergency exit and switches to lock the battery.
These features help you stay safe and comfortable when you use the excavator. The cab lets you see the boom, arm, and bucket clearly, so you can work better.
Boom, Arm, and Bucket
The boom, arm, and bucket are the parts that do the digging. You use them to dig, lift, and move things. The boom is attached to the top part and gives lifting power. The arm is connected to the boom and helps you reach farther. The bucket is at the end of the arm and does the digging.
The bucket is made from strong materials to last in tough places. Its design makes it strong and easy to fix if the edge wears out. You can pick different ground engaging tools (GET) to make the bucket last longer and easier to care for. The bucket’s weight and balance help the boom and arm last longer.
Excavator Size (Machine Weight) | Bucket Capacity (m³ or liters) | Bucket Weight (kg) |
|---|---|---|
Mini and small excavators (approx. 1 t to 4 t) | 0.05 m³ to 0.4 m³ (50 to 400 liters) | 13 kg to 360 kg |
Small to medium excavators (4 t to 8 t) | Around 0.2 m³ | 360 kg |
Medium excavators (4 t to 40 t) | 0.3 m³ to 1.5 m³ (300 to 1500 liters) | 600 kg to 1180 kg |
Large excavators (18 t to 54 t) | 0.5 m³ to 1.2 m³ | Not specified |
Very large excavators (30 t to 90 t) | 1 m³ to 5 m³ (up to 5000 liters) | 4650 kg to 5300 kg |
You need to pick the right bucket size and weight for your excavator. The boom and arm must be strong enough for the bucket. Check the boom, arm, and bucket often to find cracks or worn edges early.
Engine and Hydraulic System
The engine gives power to the excavator and runs the hydraulic system. Most excavators use diesel engines that control pollution. The engine is in the back, covered by panels. The engine’s health is important, so check for leaks, strange sounds, or warning lights.
Manufacturer | Engine Model | Engine Type | Cylinders | Displacement | Emission Standard |
|---|---|---|---|---|---|
Volvo | ISUZU 6HK1 | 4-stroke, turbocharged diesel with intercooler, water-cooled | 6 | 7.79 L | EU Stage V |
Manufacturer | Engine Model | Power Output | Displacement | Fuel Compatibility | Emission Standards | Hydraulic System Features |
|---|---|---|---|---|---|---|
Caterpillar | Cat C7.1 TTA | ~223-306 hp | 7.01 L | Biodiesel up to B20, renewable fuels | EPA Tier 4 Final, EU Stage V, Japan 2014 | Pressure-compensated proportional priority (PPPC), Load anticipation enhanced control (LEAC), Engine torque load control (ETLC) |
The hydraulic system uses fluid under pressure to move the boom, arm, and bucket. You use joysticks in the cab to control these parts. If there are hydraulic problems, the arm may not lift as much, or you might see leaks or slow movement. To stop problems, you should:
Look at hoses and connections for leaks.
Change oil filters when needed.
Keep hydraulic fluid clean and filled.
Watch the fluid temperature so it does not get too hot.
Change seals and gaskets if they wear out.
Taking care of the engine and hydraulic system keeps your excavator working well.
Undercarriage and Excavator Tracks
The undercarriage holds up the excavator and lets it move. There are two types: tracked and wheeled. Tracked excavators use chains for good grip and balance on rough ground. Wheeled excavators move faster and work best on hard surfaces.
Tracked undercarriages spread the weight, so the ride is smoother and more comfortable. The tracks are made from strong steel. The undercarriage has rollers, guide wheels, and a drive sprocket to move the tracks.
Signs of wear in the undercarriage and tracks are:
Tracks wearing unevenly.
Rollers and guide wheels getting worn.
Loose parts.
Cracks or bent pieces.
Mud and dirt making extra friction.
Note: Clean and check the undercarriage often to stop big repairs and save time.
If you see the tracks getting loose, cracks, or slipping, fix these problems right away. Keeping the undercarriage in good shape helps your excavator last longer.
Counterweight and Superstructure
The counterweight is at the back of the superstructure. It balances the boom, arm, and bucket when you work. For example, a wheel excavator’s counterweight can weigh about 3,500 kg. The superstructure holds the engine, hydraulic system, and cab. It turns on the undercarriage, so you can swing the boom and arm any way you want.
Check the counterweight to make sure it is tight and not damaged. The superstructure should turn smoothly and not leak or make strange noises. Keeping these parts in good shape keeps your excavator safe and working well.
When you learn the excavator body parts name and what they do, you can keep your machine safe and working right. Checking and caring for the boom, arm, bucket, engine, hydraulic system, undercarriage, and counterweight helps you stop breakdowns and make your equipment last longer.

Excavator Maintenance Essentials
Cleaning and Lubrication
It is important to keep your excavator clean. This helps it work well and stops breakdowns. Dirt and mud can build up on moving parts. This makes them wear out faster. Clean the machine every day to find leaks or damage early. Use a pressure washer or brush to get mud off the undercarriage and tracks. Pay close attention to the bucket, rollers, and joints.
Lubrication is just as important as cleaning. Moving parts like pins, bushings, and rollers need grease. Grease helps them move smoothly. If you do not use grease, parts will wear out quickly. You will need more repairs. Always follow the manufacturer’s schedule for lubrication. Use good lubricants that fit your excavator. Check oil and grease levels often. Add more if they are low.
Tip: Clean and grease all moving parts often. This easy habit helps your excavator last longer and work better.
Fluid and Filter Checks
Fluids and filters are very important for excavator care. You must check engine oil, hydraulic fluid, coolant, and fuel every day. If fluids are low or dirty, the machine will not work well. It could even break down. Change fluids when the manufacturer says to. Clean hydraulic fluid and filtered oil are needed for hard jobs.
Filters keep dirt out of the engine and hydraulic system. Check filters every 250 hours. Replace them every 500 hours or as the manual says. Use filters that fit your excavator. Here are the main filters you should check:
Oil filter: Takes dirt out of engine oil.
Air filter: Stops dust from getting in the engine.
Fuel filter: Keeps bad stuff out of the engine.
Hydraulic filter: Protects the hydraulic system.
Cabin air filter: Keeps the air clean for the operator.
High-pressure and low-pressure oil filters: Used in different excavators.
Magnetic and cartridge oil filters: Give extra protection and are easy to change.
Note: Always use the right filters and fluids for your excavator’s brand and model. This keeps your warranty safe and helps your machine work its best.
Track and Undercarriage Care
Taking care of the tracks and undercarriage is very important. The undercarriage holds up the whole machine and lets it move. Check track tension often. If tracks are too loose or tight, they will wear out fast. Adjust the tension to match what the manufacturer says.
Clean the tracks every day. Take off mud, rocks, and debris that can cause extra wear. Grease the rollers and moving parts to help them work well. Try not to make sharp turns on hard ground. This can hurt the tracks and undercarriage.
Here are some tips for undercarriage care:
Look for cracks, loose bolts, or worn parts.
Use the right grease for heavy machines.
Change worn rollers, sprockets, and track pads when needed.
Use strong replacement parts to make them last longer.
Callout: Good undercarriage care stops big repairs and helps your excavator last longer.
When to Repair or Replace
You need to know when to fix or change parts. This helps you avoid surprise breakdowns. Some parts wear out faster than others. Bucket teeth, hoses, filters, and seals need to be checked often. If you see cracks, leaks, or worn edges, act fast. Change broken parts before they stop working.
Here is a list of parts that need regular checks:
Part | Check Frequency | Signs You Need Repair or Replacement |
|---|---|---|
Bucket teeth | Daily | Worn, broken, or missing teeth |
Hydraulic hoses | Weekly | Cracks, leaks, or bulges |
Filters | 250-500 hours | Clogged, dirty, or damaged |
