The Cat 320 rubber-tire excavator is a powerful piece of heavy equipment, widely used in various construction and material handling operations. One of its most impressive capabilities is its ability to move heavy objects, such as Jersey barriers, which are commonly used for traffic control, construction sites, and roadwork projects. These barriers, often weighing over 2 tons each, require substantial lifting power and precision handling, and the Cat 320 excels in this task.
What is a Jersey Barrier?
Jersey barriers, also known as concrete barriers or K-rails, are used to separate lanes of traffic or create safe zones in construction zones. These barriers are made from heavy reinforced concrete and come in a variety of sizes, but the standard units usually weigh between 2,000 to 2,500 pounds (approximately 900 to 1,100 kg). They are designed to be robust and provide high-impact resistance, but their weight makes them difficult to move without the right equipment.

The Cat 320 is a part of Caterpillar's 20-ton class excavators, known for their versatility and ability to handle a range of tasks, from digging and trenching to lifting and material handling. Here are some key features of the Cat 320 that make it ideal for moving Jersey barriers:
- Rubber-Tire Mobility
The rubber-tire configuration allows the Cat 320 to move quickly across job sites without the need for trailers or cranes. This mobility is crucial when working in tight spaces, especially on urban construction sites or roadwork projects where quick repositioning is often required. The wheels give the excavator greater flexibility and speed compared to traditional tracked machines.
- Hydraulic Power
Equipped with a powerful hydraulic system, the Cat 320 has the strength to move large, heavy objects like Jersey barriers. The hydraulic lifting capacity of the arm can exceed 5,000 lbs (2,268 kg) depending on the configuration and attachments used. This enables the machine to pick up, shift, and reposition Jersey barriers with ease.
- Precision and Control
With advanced control systems, the Cat 320 provides operators with precise handling of heavy loads. The excavator’s joystick-controlled hydraulic system ensures that Jersey barriers are moved safely without risking damage to the equipment or surrounding structures. Its smooth and accurate movements are particularly important in environments where space is limited, such as road construction sites or during the setup of temporary traffic diversions.
- Extended Reach
The extended reach of the Cat 320’s arm gives it the ability to move Jersey barriers over long distances or from elevated positions. This is particularly useful when the barriers need to be stacked, rearranged, or placed in precise locations, even in challenging environments.
- Attachment Options
The Cat 320 can be equipped with various attachments, including lifting hooks, grapples, and forks, which are all designed to handle heavy objects such as Jersey barriers. This flexibility allows the machine to be adapted to different handling tasks, making it more versatile than traditional lifting equipment like cranes or forklifts.
The Cat 320 rubber-tire excavator's ability to move Jersey barriers efficiently and safely has broad implications for construction, roadwork, and infrastructure projects. Here are a few practical examples of how this machine is used:
- Road Construction and Maintenance
During road construction or maintenance projects, Jersey barriers are often used to separate work zones from active traffic lanes. The Cat 320 allows for the rapid deployment, removal, or adjustment of barriers, minimizing downtime and keeping the project on schedule.
- Traffic Control Setup
For temporary traffic diversions, particularly in urban areas, Jersey barriers are often repositioned frequently. Using a machine like the Cat 320 reduces the manual labor involved and speeds up the process. This is especially beneficial in cities with high traffic volumes or where work must be completed in short windows of time.
- Safety in Construction Zones
Moving Jersey barriers with precision not only speeds up the process but also enhances safety. Improperly placed barriers can lead to accidents or traffic flow issues, and using an excavator ensures that the barriers are securely and safely positioned each time.
Despite the Cat 320’s ability to move Jersey barriers effectively, there are a few challenges to consider when operating in certain environments:
- Ground Conditions
Although the rubber-tire configuration allows for mobility on various surfaces, poor ground conditions such as soft soil or uneven terrain can impact the machine's stability and performance. In such cases, tracks or additional stabilization may be needed to prevent the excavator from tipping or getting stuck.
- Space Limitations
Tight work areas or narrow roadways can make it difficult to maneuver the machine. The Cat 320’s compact design helps mitigate this issue, but operators must still be cautious when working in confined spaces. Proper planning and awareness of the surroundings are essential to avoid collisions or damage to nearby structures.
- Weight of Barriers
While the Cat 320 is designed to lift substantial loads, the weight and size of Jersey barriers can still be a limiting factor in some cases. Multiple lifts may be required for particularly large or heavy barriers, and ensuring the machine's hydraulic system is regularly maintained is crucial for optimal performance.
To ensure the Cat 320 continues to perform at its best when moving heavy barriers, regular maintenance is key. Here are a few tips:
- Regular Hydraulic System Checks
The hydraulic system is one of the most crucial components of the Cat 320. Regular inspections of hoses, cylinders, and fluid levels help prevent leaks or malfunctions that could affect the machine’s lifting capacity.
- Tire Maintenance
As the rubber-tire excavator relies on its tires for mobility, it’s important to inspect the tires regularly for wear and tear. Proper tire pressure and alignment help ensure that the machine can move smoothly and safely across various surfaces.
- Routine Equipment Inspections
In addition to hydraulic and tire checks, routine inspections of the arm, bucket, and attachment points are necessary to ensure that everything is in proper working order. Regularly lubricating moving parts and checking for signs of wear can help extend the life of the equipment.
The Cat 320 rubber-tire excavator’s ability to move Jersey barriers with precision and ease has made it an invaluable asset in a wide range of construction and infrastructure projects. Its combination of mobility, power, and control allows operators to handle heavy, cumbersome objects with minimal effort, improving efficiency and safety on the job site.
