Components of Crawler Excavator
Excavator tracks
The tracks of the excavator, typically made with steel-reinforced rubber, move the machine. Some excavators are wheeled but function similarly to those with tracks.
Track frame
The track frame is where the excavator tracks attach to the undercarriage, functioning similarly to axels.
Track pad
Track pads can help prevent excess noise, vibration and damage, as well as provide better traction during operation.
Track chains
Track chains are what allow an excavator to move efficiently. They function similarly to bicycle chains in that they’re made up of connected flexible links.
Track shoes
If you imagine the tracks of an excavator, the track shoes are the individual parts of the track that dig into the ground and pull the excavator along.
Track bolts
Track bolts link each track shoe together to form the entire track.
Rock guards
Rock guards are exactly what they sound like - they attach to the tracks of your excavator to protect the machine from debris and stray objects.
Sprockets
Sprockets are the mechanisms that run between the excavator track chain links. They behave like a giant bicycle sprocket, moving the chain along to propel the machine.
Rollers
Rollers are the metal wheels on an excavator undercarriage used to align the chains and move them between the sprocket and idler. There are two sets of rollers — bottom and top - to facilitate chain functionality.
Idlers
Bigger than rollers, idlers are large metal wheels within the undercarriage that help guide the excavator tracks. Idlers are the final mechanism that keep tracks running smoothly, along with the rollers and sprockets.
Main controls
This will vary depending on the machine, but this is your mission control of the excavator. This is where you’ll find the excavator’s basic controls, steering mechanisms, safety measures and more.
ROPS
ROPS stands for “rollover protective structure” and is an important safety feature. It’s meant to protect the operator in the event of a rollover.
Counterweight
The counterweight does exactly what the name implies - it counterbalances the excavator when digging, providing leverage and preventing the excavator from tipping.
Engine
The heart of the excavator, the engine is typically housed near the cab so it’s easy to access for maintenance. It’s typically powered by diesel fuel.
Hydraulic fluid tanks
As many excavators are controlled with hydraulic mechanisms, the tanks themselves are housed in the cab.
Fuel tank
Exactly what it sounds like, this is where the excavator’s fuel (as mentioned above, typically diesel) is stored.
Main control valve
The main control valve connects the engine and the hydraulic mechanisms, controlling oil pressure and powering hydraulic devices like the arm and boom.
Boom
The excavator boom is the front part that’s attached to the cab itself and holds the arm.
Arm
Sometimes referred to as the dipper or stick, the excavator arm is attached to the boom and holds the bucket. Together, the arm and boom can manipulate the bucket and get everything into position.
Bucket
The bucket is the digger on the end of the arm, responsible for all your earthmoving needs.
Cylinders
There are typically three types of cylinders on an excavator: boom, arm and bucket. The cylinders connect between each section and are responsible for articulating each. For example, the bucket cylinder connects between the arm and the bucket, and helps move the bucket back and forth.
Daily maintenance
Daily maintenance procedures follow a precise inspection checklist that includes a visual inspection with an excavator walkaround. During these steps, operators or skilled technicians check the machine for any external damages to the boom, undercarriage, and the operator’s cabin. Then, they check the engine coolant levels, search for any signs of oil leaks, and lubricate the heavily used mechanical parts.
Weekly maintenance
Every week, designated technicians inspect sprockets and other undercarriage parts to adjust the track tension. The operator conducts a longer visual inspection, and tests the excavator’s control panel, searching for any signs of malfunction and unusual noises.
Seasonal maintenance
Seasonal maintenance tasks are usually outsourced to certified technicians who take a closer look at the main components and study the state of an engine and the air filtering system. They follow a proper maintenance plan, cleaning or replacing air and fuel filters, and testing the cooling system to prevent overheating. In the end, all parts of the machine that are less affected by depreciation receive their long-awaited inspection: brake lights, windshield wipers, oil cooler, and the air conditioning system.
Unlike other large excavators that run on wheels, crawlers run on two large endless tracks and are optimal for mining and heavy-duty construction jobs. Also known as compact excavators, these excavators use hydraulic power mechanisms to lift heavy debris and soil.
Their chain wheel system allows them to slide down and scale hills with less risk, making them suitable for grading hilly areas and landscaping uneven terrain. While slower than other excavators, crawlers provide greater balance, flexibility and stability overall.
How to Choose the Right Crawler Excavator
Accessing ground conditions is extremely important while selecting the type of excavator needed at the jobsite. Generally, crawler excavators work very well when used for excavating, grading, and site development. For these applications, they can be fitted with various attachments. Some crawler excavators are even designed with reduced-tail-swing configurations which make them good for limited-space commercial or residential jobsites or new road and bridge construction projects. If the ground condition is loose or slurry, you should definitely select a long crawler excavator with a wider track shoe configuration for higher adaptability.
This is another important factor to be considered before selecting any heavy equipment like a crawler excavator. Generally, crawler excavators are the best for heavy-duty digging and lifting applications as they can maintain great contact with the ground due to their tracked undercarriage, thereby, creating a stable machine (as against the wheel excavators that depend on their tires, a dozer blade, and outriggers for their stability). In fact, the tracks of the crawler excavator offer excellent traction and a good mass distribution over their entire contact surface.
Crawler excavators as against wheel excavators do not have wheels and hence, cannot be transported easily by road. So, if you need to move your crawler excavator between various jobsites, then you need to account for its transportation cost before only. In fact, for transportation, the crawler excavators need to be matched to appropriate-sized trailers. Thus, the transportation cost associated with a crawler excavator is high as compared to wheel excavators. However, in cases of usage of crawler excavator in mining or quarries, the equipment need not be moved as it will be needed at one location only for entire of its life. That said, typically crawler excavators are used when you don’t have to move the equipment too much in uneven areas or on soft ground. Further, the travel speed of a crawler excavator does not exceed 6km/h, so they are used for applications where the excavator does not have to travel frequently over significant distances.
Before making the purchase decision, you should also consider the ability of the crawler excavator to be paired with a variety of attachments as this can help you to perform different tasks at the jobsite. Various common attachments for crawler excavator include hydraulic breaker for demolishing existing structures and concrete or asphalt, grapple for land clearing, clamshell for material unloading, quick coupler for faster work tool change over, a trenching bucket to dig foundation footings or excavate for underground utilities, or a plate compactor to finish trenches.
As the crawler excavator’s are designed for use in rough and uneven tough underfoot conditions, their undercarriage consists of many moving components and wear items that need to be maintained for the machine to function properly. Hence, you should consider the maintenance cost of crawler excavator before making the purchase decision.
