Essential Components of an EX200 Excavator’s Undercarriage: A Comprehensive Guide

Dec 21, 2023 | News

The undercarriage of the EX200 excavator is a complex assembly of various components that work together to provide stability, mobility, and traction. By understanding the functions and significance of excavator undercarriage parts, such as ex200 bottom rollers, ex200 carrier rollers, front idlers, idlers, excavator sprocket, track chains, track groups, ex200 track links, ex200 track rollers, and ex200 up rollers, operators and maintenance personnel can ensure optimal performance and longevity of their EX200 excavators.

Bottom Rollers (EX200-5):

The EX200-5 model utilizes bottom rollers, also known as excavator track roller, to support the weight of the excavator and provide a smooth surface for the track chain to roll on. These rollers reduce friction and wear, ensuring optimal performance and longevity of the undercarriage.

Carrier Rollers (EX200-5):

Positioned on the upper part of the undercarriage, the excavator carrier roller of the EX200-5 support the track chain as it moves around the excavator. They help distribute the weight of the machine evenly and reduce stress on the track chain, contributing to the overall stability and reliability of the excavator.

Front Idlers (EX200-5):

Located at the front of the undercarriage, the ex200 front idlers play a crucial role in guiding the track chain onto the sprockets. They maintain proper track tension and prevent the chain from derailing, ensuring smooth operation and minimizing the risk of accidents.

Idlers (EX200-5):

Additional rollers known as excavator idlers are strategically placed along the undercarriage of the EX200-5 to support the track chain. These ex200 idlers help reduce friction and wear on the chain, contributing to its durability and overall performance.

Sprockets (EX200-5):

The ex200 sprockets are toothed wheels located at the rear of the undercarriage. They engage with the track chain and provide the driving force for the excavator’s movement, enabling it to navigate various terrains efficiently.

Track Chains (EX200-5):

The ex200 track chains, also referred to as crawler tracks, are continuous metal loops that wrap around the sprockets and idlers of the EX200-5. These chains provide traction and enable the excavator to move over uneven surfaces with ease, ensuring exceptional mobility and versatility on construction sites.

Track Groups (EX200-5):

The ex200 track groups encompass the complete assembly of track chains, sprockets, idlers, and other components that form the undercarriage. These groups are designed to work in harmony, providing stability, mobility, and traction for the excavator.

Track Links (EX200-5):

The ex200 track links are the individual segments that make up the track chain. Connected by pins and bushings, these excavator links form a flexible and durable track, capable of withstanding the rigors of construction environments.

Track Rollers (EX200-5):

Located between the excavator track link, the track rollers of the EX200-5 support the weight of the excavator and reduce friction and wear on the track chain. These rollers ensure smooth movement and contribute to the overall efficiency and reliability of the undercarriage.

Up Rollers (EX200-5):

Positioned at the top of the undercarriage, the up rollers of the EX200-5 guide the track chain as it moves around the excavator. They prevent the chain from derailing and maintain proper track tension, minimizing the risk of accidents and ensuring optimal performance.
