Wheeled excavators are gaining popularity in North America, especially among local government road departments and municipalities. These versatile machines are increasingly used for various tasks, including ditch work, landscaping, and utility jobs. Their growing adoption is challenging the misconception that compact
wheeled excavators are unstable.
Wheeled excavators can handle uneven terrain without damaging their undercarriages, maintaining stability even on inclines while carrying loads. In addition to their operational capabilities, they come with enhanced safety features, such as side entry to the cab, which eliminates the need for operators to climb over attachments. Some models are equipped with load-sensing hydraulic systems that optimize engine power, enhancing both responsiveness and control.
Despite being on wheels, these excavators can be operated using only a joystick, which allows for travel speeds up to 12 mph. This feature, known as “Comfort Drive Control,” makes them highly convenient and efficient for urban projects.
Advancements in Construction Equipment: Tracks and Tires
In North America, construction equipment often features wide tracks for increased stability. In contrast, manufacturers overseas design equipment with tracks that can be bolted over tires, offering higher speeds and greater versatility. This innovative approach is gaining traction among North American operators, who are increasingly seeking adaptable tracks for tight and varied work environments.
As construction sites become more constrained, equipment with smaller footprints is in higher demand. Some tracked models now come with optional rubber track shoes, which are beneficial for use on delicate surfaces like asphalt. These rubber shoes are detachable, reducing noise and vibration while offering a cost-effective solution for maintaining the excavator’s track system.
Choosing the Right Excavator: Wheeled vs. Tracked
When deciding between wheeled and tracked excavators, it's important to consider the specific requirements of each job. Wheeled excavators, being lighter and more suitable for long-distance travel, offer significant savings in maintenance and transport costs. They are particularly effective in urban environments where minimizing road damage and fast travel are crucial.
Contrary to some beliefs, wheeled excavators do not compromise on stability compared to tracked models. They offer comparable breakout force, digging depth, and power. These excavators can drive directly to job sites, eliminating the need for additional transport equipment and further reducing costs. They can also tow trailers, which decreases transport expenses even more.
The economic benefits of wheeled excavators extend beyond the initial purchase. Operators do not need a commercial driver’s license (CDL) to operate them, making them more accessible and reducing personnel costs.
Versatility and Innovation in Wheeled Excavators
Wheeled excavators are particularly valuable in confined spaces, such as working within a single lane of traffic. More operators are seeking models with two-piece articulating booms, which offer greater flexibility to navigate around obstacles and enhance lift capacity in tight areas.
Traditionally favored for urban areas with solid ground, wheeled excavators are now being recognized for their potential in a broader range of environments. As multifunctional excavators become more common, they offer contractors the flexibility to use the same attachments as crawler excavators, reducing the need for multiple machines.
Looking Ahead: The Future of Excavator Technology
As demand for versatile, user-friendly equipment grows, manufacturers are responding with innovative solutions for both wheeled and tracked excavators. Wheeled excavators are streamlining operations on job sites by reducing the amount of equipment needed. This trend is expected to continue as these machines prove invaluable for diverse applications, from urban construction to expansive rural projects.
Tips for Choosing Between Tracks and Tires
Understand the Differences: Tracks and tires each have unique benefits for different applications. Wheeled equipment like compact wheel loaders excel on solid, dry ground and are ideal for tasks such as loading, landscaping, and snow removal. Compact track loaders, on the other hand, are better suited for uneven or wet terrain and are excellent for heavy lifting and using various attachments.
Assess Jobsite Needs: Evaluate the specific requirements of your job site. If higher travel speeds and mobility between sites are crucial, wheeled excavator might be the better option. For off-road or soft terrain work, tracks may be more appropriate.
Incorporate Both Tracks and Tires: Leveraging the strengths of both tracks and tires can enhance operational efficiency and profitability.
By understanding the unique advantages of wheeled and tracked excavators, operators can make informed decisions that maximize efficiency and reduce costs in their construction projects.
