Introduction to Track Components
To begin understanding the key differences between steel tracks and rubber tracks, it’s important to briefly review the basic components of any track system. All tracks are made up of several interconnected parts that work together to provide traction and mobility.
The Track Pad
The track pad is the durable, flexible piece that makes direct contact with the ground. This is the part of the track that bears the weight of the vehicle and allows it to move smoothly across various surfaces. Steel Tracks and Rubber Tracks use hardened metal pads while rubber tracks utilize resilient rubber or polyurethane compounds for the pads.
The Link Pins and Bushings
Link pins connect individual track pads together to form a continuous loop or band. Flexible bushings located around the link pins allow the track sections to articulate or flex as the vehicle moves. Proper lubrication of these bushings is crucial to long-lasting track performance.
The Track Frame and Rollers
A sturdy frame underneath the vehicle carries and guides the track belt. Small rollers within the track frame contact the underside of the track, helping to distribute weight and power the track around the drive sprocket or idler wheels.
Track Material Differences
With an understanding of basic track components, we can now explore key differences in the materials used for steel tracks versus rubber tracks:
Steel Tracks
As the name implies, steel tracks are constructed entirely from hardened metal components. The interlocking track pads are made of tempered steel alloys designed for strength, rigidity and durability. Steel tracks provide excellent load-bearing capacity and can withstand heavy impacts or abrasive conditions. However, they generate more noise and vibration compared to rubber tracks. Proper lubrication is also needed to prevent freezing or seizing up in cold weather.
Rubber Tracks
Rubber tracks substitute flexible rubber, polyurethane or thermoplastic elastomer materials for the track pads. These rubber compounds conform better to uneven terrain for increased flotation and traction. Overall noise and shock absorption qualities are improved over steel tracks as well. However, rubber tracks are generally not as durable or abrasion-resistant as steel in heavy duty applications involving rocks or debris. Their flexing characteristics also make rubber tracks more prone to premature wear if improperly maintained.
Performance Comparison in Various Conditions
Off-Road Traction
For driving over soft, unstable ground like mud or wet grass, rubber tracks provide a clear advantage. Their continuous and conforming contact distributes weight excellently without compromising mobility. Steel tracks can potentially cut ruts or sink deeper depending on subsurface conditions.
Hard Surface Performance
On firm, compacted surfaces like gravel, pavement or hard-packed dirt, steel tracks deliver reliably smooth operation. Their flat contact profile rolls with low rolling resistance. Flexing rubber tracks can sometimes hesitate or slip initially when driving onto paved areas.
Durability and Longevity
Steel tracks are harder-wearing and longer-lasting, especially in abrasive environments carrying loads of debris, rocks or other harsh cargo. Their rigid construction holds up well to hard impacts that could tear or damage rubber track pads over time. Rubber tracks generally have lower durability and may require more frequent replacement of worn parts.
Cold Weather Operation
Steel tracks function very reliably in frozen conditions if properly lubricated and maintained. Rubber becomes brittle and loses flexibility at low temperatures, negatively impacting performance and shortening track life if used extensively in arctic climates.
Noise and Vibration Levels
Rubber tracks run much quieter and cushion shocks/vibrations better, creating a more comfortable riding environment. Steel tracks are louder and transfer more noise/impacts to the operator and equipment structure.
Cost Comparison
Initial purchase price of steel tracks tends to be lower than comparably-sized rubber tracks. However, operating costs even out long-term since rubber tracks usually go longer between component replacements or repairs if worn parts are addressed promptly. Overall lifecycle costs can then favor one material over the other depending on specific application needs.
Choosing the Right Track Material
In conclusion, both Steel Tracks and Rubber Tracks and rubber tracks have their strengths and weaknesses depending on the equipment application, expected work conditions, budget, and other factors. Consulting experienced professionals can help identify which track material and design options will provide optimum performance and value for a given operational need over the intended service life. With proper selection and ongoing maintenance, either track type can deliver reliable mobility and flotation for equipment working in challenging jobsite environments.
