What Parameters Are Determined By The Undercarriage of the Excavator?

The undercarriage of the excavator not only supports the weight of the whole machine, but also bears the stability and working efficiency under complex working conditions. Therefore, the performance parameters of the undercarriage are crucial to the use of the excavator. So, what parameters are determined by the undercarriage of the excavator? Which undercarriage parts are these parameters related to?

Key parameters of the undercarriage of the excavator and its core parts

Track Gauge

The track gauge refers to the distance between the center lines of the two tracks, which directly affects the stability of the excavator.

• Core components: The adjustment of the track gauge depends on the design and layout of the track rollers and track frames. Wide-gauge undercarriage are usually equipped with extended track frames and more track rollers to enhance the support force, thereby improving the stability of the whole machine.
• Application scenarios: Undercarriage with a larger track gauge is more suitable for heavy-duty operations or steep slope construction, while a smaller track gauge is suitable for flexible operations in narrow areas.

Track Width

The track width directly affects the ground contact area and unit pressure, and determines the passability and grip of the excavator.

• Core components: The width of the track shoe is the key. Wide track shoes are usually combined with reinforced track links and tensioning devices to ensure load-bearing capacity and track stability.
• Application scenarios: Wide tracks are suitable for soft or muddy ground, such as farmland and wetland construction; narrow tracks are more suitable for hard ground and urban construction sites.

Track pitch

The track pitch refers to the distance between the center points of two adjacent track links, which affects the bending and running smoothness of the track.

• Core components: Track links and track pins are the core components that determine the pitch. High-quality track link materials and precision processing can extend the service life and reduce the risk of track shedding.
• Application scenarios: Tracks with smaller pitches are more suitable for light excavators and provide higher flexibility, while tracks with larger pitches are suitable for heavy equipment and enhance load capacity.

Driving Wheel Diameter

The diameter of the driving wheel determines the power transmission efficiency and the running speed of the track.

• Core components: The fit between the drive wheel and the track is the key. The high-quality drive wheel tooth design can reduce slippage and enhance the smoothness of power output.
• Application scenarios: Larger drive wheels are suitable for high-speed excavators, while small-diameter drive wheels are suitable for slow and heavy-load operations.

Track Roller Arrangement

The number and distribution of track rollers directly affect the uniformity of the force on the track.

• Core components: A chassis design with a large number of track rollers can disperse the weight more evenly and reduce the wear of the track and the ground.
• Application scenarios: Complex terrain or high-intensity operations require more high-strength track rollers to extend the service life.

Undercarriage height

The undercarriage height determines the passability of the excavator, especially in rugged terrain.

• Core components: The structural design of the sprocket wheel and the track frame plays a decisive role in the chassis height. High-strength sprocket wheels can improve the stability of the machine and reduce the impact on the ground.
• Application scenarios: Mountain construction that requires high passability usually uses a higher chassis design.

Load Capacity

The load capacity of undercarriage parts affects the operation capacity of the whole machine, especially for heavy-duty operations.

• Core components: The load capacity is determined by the overall design and material strength of the crawler, roller and sprocket. Tracks and rollers made of wear-resistant alloy materials can bear greater weight and extend their service life.
• Application scenarios: Heavy excavators require chassis parts with high load capacity to cope with mines or large-scale earthwork operations.

How to choose high-quality excavator undercarriage parts?

Focus on material quality
Choose wear-resistant and impact-resistant alloy steel chassis parts to ensure excellent performance in high-intensity operations. High-quality materials can extend service life and reduce replacement frequency.

Focus on processing technology
Precision-machined undercarriage parts can effectively avoid assembly errors and improve operating efficiency. Check the manufacturer’s processing equipment and process standards to ensure product dimensional stability.

Evaluate product adaptability
The undercarriage parts must be highly matched with the model and working conditions of the excavator. Choose undercarriage parts suitable for width, pitch and track gauge according to the specific working environment.

Choose a reliable brand
The reputation of the brand is an important guarantee of product quality. Choose experienced manufacturers such as GFM to ensure product quality and after-sales service.
