What are the disadvantages of a track motor excavator?

As a supplier of track motor excavators, I've witnessed firsthand the widespread use and many advantages of these powerful machines in various industries. However, like any equipment, track motor excavators come with their fair share of disadvantages. In this blog post, I'll delve into some of the key drawbacks that potential buyers and operators should be aware of.

1. High Initial Cost

One of the most significant disadvantages of track motor excavators is their high initial purchase price. These machines are complex pieces of equipment that incorporate advanced technology, powerful engines, and durable components. The cost of manufacturing and engineering these excavators is reflected in their price tag, making them a substantial investment for any business.

For small to medium - sized construction companies or contractors with limited budgets, the upfront cost of a track motor excavator can be a major deterrent. This high cost may force them to consider alternative equipment or opt for used machines, which come with their own set of risks such as potential mechanical issues and shorter remaining lifespan.

2. Limited Mobility on Certain Terrains

While track motor excavators are known for their excellent traction on soft and uneven ground, they have limitations when it comes to mobility on other types of terrains. For instance, on hard - paved surfaces like concrete or asphalt, the tracks can cause significant damage. The continuous movement of the tracks can wear down the surface, leaving behind scratches and grooves. This not only damages the pavement but also increases the maintenance cost for the property owners.

Moreover, track motor excavators are relatively slow when it comes to long - distance transportation. They cannot be easily driven on public roads like wheeled vehicles. Instead, they need to be transported using specialized trailers, which adds to the transportation cost and time. If a construction project requires the excavator to be moved frequently between different sites, this limited mobility can be a major drawback.

3. High Maintenance Requirements

Track motor excavators are subject to a high degree of wear and tear due to their heavy - duty operation. The tracks, in particular, are constantly under stress as they support the weight of the machine and provide traction. Over time, the tracks can become worn, cracked, or damaged, requiring regular inspection and replacement.

The hydraulic systems in these excavators are also complex and require careful maintenance. Hydraulic leaks can occur, which not only waste hydraulic fluid but can also lead to reduced performance and potential damage to other components. Regular fluid changes, filter replacements, and inspections are necessary to keep the hydraulic system in good working condition.

In addition, the engine, transmission, and other mechanical components need regular servicing. The cost of maintenance parts and labor can be quite high, especially for specialized components. For example, the Disc Distribution Type Motors used in some track motor excavators are precision - engineered and can be expensive to replace if they malfunction.

4. Environmental Impact

The operation of track motor excavators has a notable environmental impact. These machines are typically powered by diesel engines, which emit pollutants such as carbon monoxide, nitrogen oxides, and particulate matter. These emissions contribute to air pollution and have negative effects on human health and the environment.

The noise generated by track motor excavators is also a concern. The loud engine noise and the sound of the tracks moving can be a nuisance to nearby residents, workers, and wildlife. In areas with strict noise regulations, such as residential neighborhoods or wildlife sanctuaries, the use of track motor excavators may be restricted or require special permits.

5. Operator Skill Requirements

Operating a track motor excavator requires a high level of skill and training. The controls of these machines are complex, and an inexperienced operator can cause accidents, damage to the equipment, or injury to themselves and others.

Maneuvering the excavator, especially in tight spaces, requires precise control of the tracks, boom, and bucket. The operator needs to have a good understanding of the machine's capabilities and limitations to perform tasks safely and efficiently. Training programs for track motor excavator operators can be time - consuming and expensive, and not all companies may have the resources to provide comprehensive training.

6. Space Requirements

Track motor excavators are large and bulky machines. They require a significant amount of space for operation and storage. In construction sites with limited space, it can be challenging to maneuver the excavator without causing damage to other equipment or structures.

When it comes to storage, these machines need a secure and dry area to prevent rust and damage. The large size of the track motor excavator also means that it may not fit into standard storage facilities, requiring additional space or custom - built storage solutions.

7. Component Complexity and Compatibility

Track motor excavators are made up of numerous components, and the complexity of these components can be a disadvantage. Different models of track motor excavators may use different types of components, and finding compatible replacement parts can be a challenge.

For example, the Gerotor Motor BMR160 and Gerotor Motor BMR Series are specific types of motors that may not be interchangeable with motors from other manufacturers or models. This can lead to delays in getting the machine back up and running if a component fails.

Despite these disadvantages, track motor excavators still have their place in the construction and mining industries. Their ability to work on soft and uneven ground, high digging power, and stability make them indispensable for many projects. However, it's important for potential buyers to be aware of these drawbacks so that they can make an informed decision.
