Introduction
The track chain is a crucial component of tracked machinery such as bulldozers, excavators, and track loaders. The chains are responsible for providing the traction needed to move the vehicle across rough terrain and provide a stable base for the heavy machinery to work on. There are several types of track chains available, each with its own unique advantages and disadvantages. In this article, we will explore each of these types in detail.
Rubber Track Chains
The rubber track chain is used primarily on smaller machines such as excavators and skid steers. These chains are made up of rubber pads that are connected to a metal frame, similar to a conventional track chain. The rubber pads provide better traction and stability on soft surfaces like dirt and sand, while also reducing vibration and noise. Additionally, these chains will not damage paved surfaces like asphalt or concrete.
However, rubber track chains are not as durable as steel chains and are not recommended for use on hard surfaces like rocks or concrete. They are also more expensive and can wear out more quickly than traditional steel chains.
Sealed Track Chains
Sealed track chains are designed to keep debris and dirt out of the chain links, extending the life of the chain. These chains use a special seal design that rings around the pins and bushings, preventing dust and dirt from entering the chain. Sealed chains require less maintenance and have a longer lifespan than traditional track chains.
However, sealed chains are typically more expensive than unsealed chains and can be more difficult to repair if they do break down. They also tend to be heavier, which can impact fuel efficiency.
Split Track Chains
Split track chains are designed to make maintenance and repairs easier. These chains are composed of two halves that can be easily disassembled and reassembled, allowing quick access to the chain links. This design is especially useful in situations where the machinery is frequently moved and needs to be disassembled regularly.
However, split track chains are not as strong as traditional one-piece chains. They are also more expensive and can be more difficult to find replacement parts for.
Greased Track Chains
Greased track chains are designed to reduce friction and wear on the chain links. These chains are constantly lubricated by a grease reserve that is built into the chain itself. Greased chains require less maintenance and have a longer lifespan than ungreased chains.
However, greased chains can be more expensive than ungreased chains and can be difficult to repair if they do break down. They can also be heavier, which can impact fuel efficiency.
Lifetime Sealed Track Chains
Lifetime sealed track chains are the most durable type of track chain available. These chains use a special seal design that completely seals the pins and bushings, preventing any debris or dirt from entering the chain. Lifetime sealed chains require no maintenance and have a lifespan that can last the entire lifespan of the machinery.
However, lifetime sealed chains are typically the most expensive type of chain available. They are also heavier, which can impact fuel efficiency, and can be more difficult to repair if they do break down.
Conclusion
In conclusion, there are several types of track chains available, each with its own unique advantages and disadvantages. Rubber track chains are ideal for soft surfaces and provide better traction and stability, but they tend to wear out more quickly and are more expensive. Sealed track chains are designed to keep debris out of the chain and require less maintenance, but they can be more expensive and heavier. Split track chains are designed for easy maintenance and repair but are not as strong as traditional chains. Greased chains are self-lubricating and have a longer lifespan, but they can be more expensive and heavier. Lifetime sealed chains are the most durable of all chains but are also the most expensive and heaviest. When choosing a track chain, it is important to consider the terrain the machinery will be operating on and the level of maintenance required.
