The undercarriage of an excavator is a crucial component that facilitates the machine's mobility, stability, and overall operational efficiency. It supports the excavator's weight and provides the necessary traction to navigate various terrains. The undercarriage consists of several key parts:
Track Frame: The foundation of the undercarriage, the track frame, houses and supports other components. It provides structural integrity and ensures that the tracks are aligned correctly.
Track Chains: The track chains, or track links, are the continuous loops that make contact with the ground. They are made up of interconnected metal links that allow the excavator to move.
Track Shoes: Attached to the track chains, track shoes (or pads) provide the surface area that makes contact with the ground. They come in different widths and designs to suit various ground conditions, offering either increased traction or reduced ground pressure.
Sprockets: Sprockets are toothed wheels that engage with the track chains, driving the tracks forward or backward. They are typically powered by the excavator's hydraulic motor.
Rollers: There are two types of rollers in an excavator's undercarriage:
Carrier Rollers: Located on the upper part of the track frame, these rollers support the weight of the track chains, reducing sagging and ensuring smooth movement.
Track Rollers: Positioned along the bottom of the track frame, track rollers bear the excavator's weight and facilitate the movement of the tracks over the ground.
Idlers: Idlers are wheel-like components located at the front of the track frame. They help guide the track chains and maintain proper tension. Some excavators also have rear idlers to support the tracks.
Track Adjusters: Track adjusters are hydraulic or spring mechanisms that maintain the proper tension in the track chains. They ensure that the tracks are neither too tight nor too loose, which can affect performance and wear.
Drive Motor and Final Drive: The drive motor powers the movement of the tracks, and the final drive transmits this power to the sprockets. The final drive often includes a gearbox that increases torque and reduces speed, enhancing the excavator's ability to navigate difficult terrain.
Track Tensioners: These components adjust and maintain the tension of the track chains, ensuring they operate efficiently and reducing wear on other undercarriage parts.
Bushings and Pins: These small yet critical parts connect the links in the track chains, allowing flexibility and movement. Bushings protect the pins from wear and tear.
Track Guards and Guides: These components help keep the track chains aligned and prevent them from derailing during operation.
Each of these components plays a vital role in the performance and durability of the excavator's undercarriage, ensuring the machine can move efficiently and withstand the demands of various work environments.
Final Drive Mechanics
The final drive is a critical component of an excavator's undercarriage, responsible for transmitting power from the hydraulic motor to the tracks, allowing the machine to move. Here’s a detailed explanation of how the final drive is powered, the components within it, and how the sprockets drive the tracks:
Powering the Final Drive
Hydraulic System: The final drive is primarily powered by the excavator's hydraulic system. Hydraulic fluid, under high pressure, is pumped from the hydraulic pump to the hydraulic motor located in the final drive assembly. This fluid power is converted into mechanical energy by the hydraulic motor.
Hydraulic Motor: The hydraulic motor receives pressurized hydraulic fluid, which forces the motor to rotate. This rotation generates the mechanical force needed to drive the final drive components.
Components of the Final Drive
Hydraulic Motor: As mentioned, the hydraulic motor is the initial component that converts hydraulic power into mechanical rotation. It forms the input stage of the final drive.
Gearbox: The gearbox is a critical part of the final drive, usually consisting of a series of gears (planetary gears) that reduce the high-speed, low-torque input from the hydraulic motor into a low-speed, high-torque output. This reduction is necessary to provide the force required to move the heavy excavator over rough terrains.
Planetary Gear System: Within the gearbox, the planetary gear system includes a central sun gear, planet gears, and a ring gear. The hydraulic motor drives the sun gear, which in turn drives the planet gears. These gears rotate around the sun gear and inside the ring gear, effectively reducing the speed and increasing the torque of the output shaft.
Output Shaft: The output shaft is connected to the planetary gear system and transmits the reduced speed, high-torque power to the sprocket.
Bearings and Seals: Bearings support the rotating components within the final drive, ensuring smooth operation and longevity. Seals prevent hydraulic fluid and lubricants from leaking, maintaining the integrity of the system.
Driving the Tracks
Sprockets: The output shaft of the final drive is connected to the sprockets. Sprockets are toothed wheels that mesh with the track chains. As the output shaft rotates, it turns the sprockets.
Track Chains: The sprockets engage with the links in the track chains. Each tooth of the sprocket fits into a corresponding gap between the track chain links, allowing the sprocket to pull the track along as it rotates.
Movement of Tracks: As the sprockets turn, they drive the track chains forward or backward. The continuous loop of the track chains moves over the rollers and idlers, propelling the excavator in the desired direction.
Traction and Stability: The design of the tracks, combined with the force provided by the final drive, allows the excavator to move over various terrains with stability and traction. The even distribution of the machine's weight across the tracks minimizes ground pressure, enhancing mobility and reducing the risk of sinking or slipping on soft or uneven ground.
The final drive is a robust and essential part of the excavator’s undercarriage, transforming hydraulic power into the mechanical force needed to drive the tracks. It consists of a hydraulic motor, a planetary gear system, and an output shaft connected to the sprockets. The interaction between the sprockets and the track chains enables the excavator to move, providing the necessary traction and stability to operate efficiently in various conditions.
Excavator Rotation
An excavator can pivot or rotate in place without moving forward or backward by using a maneuver called "counter-rotation" or "pivot steering." This maneuver is made possible by independently controlling the tracks on each side of the excavator. Here’s a detailed explanation of how this process works:
Mechanics of Pivot Steering
Independent Track Control: The excavator’s tracks are controlled by separate hydraulic motors. This allows the operator to control the speed and direction of each track independently. When performing a pivot turn, one track moves in the opposite direction to the other.
Hydraulic Control System: The hydraulic control system, operated by the excavator's joystick or control levers, directs hydraulic fluid to the motors of each track. By manipulating these controls, the operator can cause one track to move forward and the other to move backward simultaneously.
Pivot Steering Process
Track Direction: To pivot to the left: To pivot to the right:
The right track moves forward.
The left track moves backward.
Rotation Around the Central Axis: With one track moving forward and the other moving backward, the excavator rotates around its central axis. This rotation allows the machine to change direction without translating forward or backward.
Equal and Opposite Motion: The speeds of the tracks are carefully controlled so that the forward motion of one track exactly counteracts the backward motion of the other. This ensures that the excavator remains in the same position horizontally, merely rotating in place.
Practical Considerations
Coordination: The operator must coordinate the controls to achieve smooth and precise pivoting. Modern excavators often have intuitive control systems that make this easier.
Surface Conditions: The effectiveness of pivot steering can be influenced by the surface on which the excavator is operating. Soft or uneven ground may require more careful control to avoid excessive wear on the tracks and undercarriage.
Track Wear: Frequent pivot steering can lead to increased wear on the tracks and undercarriage components due to the high friction involved. Operators typically use this maneuver sparingly and only when necessary.
Pivot steering allows an excavator to rotate around its central axis without moving forward or backward. This is achieved by independently controlling the hydraulic motors of each track, causing one track to move forward and the other backward simultaneously. This maneuver is crucial for repositioning the excavator in tight spaces or when precise orientation adjustments are needed on the job site.
The ability of an excavator to pivot or rotate in place without moving forward or backward offers several significant advantages:
1. Enhanced Maneuverability in Tight Spaces
Confined Worksites: In construction, demolition, or mining operations, space is often limited. Pivot steering allows the excavator to reorient itself without needing additional clearance, making it easier to operate in narrow or confined areas.

2. Improved Operational Efficiency
Time Savings: The ability to rotate in place reduces the time required to reposition the excavator between tasks, allowing operators to complete jobs more quickly and efficiently.
Simplified Movements: Pivot steering simplifies the process of moving around obstacles or adjusting the machine’s orientation, streamlining workflow and reducing downtime.
3. Reduced Wear and Tear on the Undercarriage
Minimized Travel Distance: By pivoting in place, the excavator reduces the need for longer movements back and forth, which can cause excessive wear on the tracks and undercarriage components.
Lower Maintenance Costs: Less frequent movement reduces the strain on the tracks and other undercarriage parts, leading to longer component life and lower maintenance costs.
4. Increased Safety
Stable Positioning: When an excavator can rotate in place, it maintains a stable base, reducing the risk of tipping or losing balance, especially when working on uneven or unstable ground.
Controlled Movements: The operator can make controlled and deliberate movements, enhancing safety around other workers and equipment on the site.
5. Versatility in Task Execution
Multi-Directional Work: The excavator can quickly change the direction it is facing, allowing it to switch between tasks such as digging, lifting, and dumping with minimal repositioning.
Adaptability to Different Tasks: The ability to pivot makes the excavator more adaptable to various job requirements, from trenching to material handling, improving its overall utility.
6. Better Utilization of Job Site Space
Optimized Space Usage: In crowded job sites, every square meter counts. Being able to pivot in place ensures that the excavator can operate effectively without requiring large areas for turning and repositioning.
Proximity to Work Areas: The excavator can stay closer to the work area, reducing the need to move back and forth, which can be particularly beneficial in urban construction sites or areas with restricted access.
The ability of an excavator to pivot in place provides enhanced maneuverability, improved operational efficiency, reduced wear and tear on the undercarriage, increased safety, greater versatility in task execution, and better utilization of job site space. These advantages make pivot steering a valuable feature for excavators, contributing to their effectiveness and reliability in various work environments.
Changing Excavator Tracks
Changing the tracks of an excavator by using the bucket to lift one side off the ground is a practical and effective method. Here’s a step-by-step explanation of how this process is typically done:

Lower the Bucket: Extend the boom and lower the bucket to the ground in front of the excavator. The bucket should be positioned flat on the ground, providing a stable surface to lift the machine.
Lift the Excavator: Using the controls, push the boom downward, which will lift the front of the excavator off the ground. Continue to extend the boom until one side of the excavator’s undercarriage is elevated sufficiently to allow for track removal.
Secure the Excavator: For added safety, place sturdy blocks or supports under the frame of the excavator to prevent it from accidentally lowering while you are working on the tracks. Ensure these supports are stable and capable of bearing the weight of the machine.
Remove the Track:
Release Tension: Locate the track adjuster and release the tension on the track. This is typically done by loosening a grease fitting or a similar mechanism to allow the idler to retract.
Remove the Track: With the tension released, the track should become loose. Carefully remove the track by guiding it off the sprockets, rollers, and idlers. This may require additional help or tools to maneuver the heavy track.
Inspect Components: Before installing the new track, inspect the sprockets, rollers, and idlers for any signs of wear or damage. Replace any components that are excessively worn to ensure the new track functions properly.
Install the New Track:
Position the New Track: Place the new track around the sprockets, rollers, and idlers. Ensure it is properly aligned.
Tighten the Track: Adjust the track tensioner to the correct specification. This usually involves adding grease to the tensioner to push the idler forward and tighten the track. Check the track tension according to the manufacturer’s guidelines.
Lower the Excavator: Once the new track is properly installed and tensioned, use the controls to lower the excavator back to the ground. Remove any supports or blocks used to stabilize the machine.
Final Inspection: Perform a final inspection to ensure the track is correctly installed and tensioned. Check for any signs of misalignment or other issues.
Changing the tracks of an excavator by using the bucket to lift one side involves positioning the bucket on the ground, using it to lift the machine, securing the excavator with supports, removing the old track, installing the new track, and performing necessary inspections. This method leverages the excavator’s hydraulic power to simplify the track replacement process, making it a practical and efficient approach for maintenance.
Track Tension
Ensuring that the tracks of an excavator are correctly tightened is crucial for optimal performance and longevity of the machine. Here’s how you can make sure the tracks are properly tensioned, along with the downsides of having tracks that are too tight or too loose:
