The Caterpillar 320B LU (Long Undercarriage) is a well-known model in the Caterpillar family of excavators. Its reputation for being both versatile and powerful has made it a go-to choice for contractors and operators in construction, landscaping, and excavation industries. While newer models have since been released, the 320B LU remains a staple in many fleets due to its robust design and reliability. This article takes a closer look at the features of the CAT 320B LU, highlights some common user experiences, and offers insights into its maintenance and capabilities.
Overview of the CAT 320B LU
The CAT 320B LU is part of the B-Series line of Caterpillar hydraulic excavators, known for their strength, comfort, and operational versatility. The "LU" designation stands for "Long Undercarriage," which means the machine has a longer track frame compared to the standard 320B. This design offers improved stability, better reach, and the ability to work on rough terrain more efficiently.
Key Features:
Many users of the CAT 320B LU praise the machine for its solid performance, particularly its ability to handle rough terrains and heavy-duty tasks. Contractors often mention its long reach as a standout feature, particularly when working in confined spaces or when deeper digging is required. The long undercarriage not only boosts the machine's stability but also its productivity, making it easier to operate when lifting heavy loads or handling large-scale excavation projects.
The hydraulic system’s responsiveness is another highlight. The 320B LU can efficiently control multiple operations simultaneously, without sacrificing power or precision. Whether working with a bucket or a specialized attachment, operators often report smooth transitions between movements, which improves overall job site efficiency.
However, like any heavy machinery, regular maintenance is essential. A common issue cited by operators is the machine's need for frequent lubrication, particularly on the boom and bucket pins. This is typical for hydraulic machines, but it’s crucial for maintaining the long-term durability of the 320B LU. Additionally, some users have noted the importance of keeping the cooling system clean, as this helps avoid overheating during extended use.
Common Maintenance Issues
While the CAT 320B LU is generally considered a durable machine, there are a few common maintenance concerns that operators should be aware of. These include:
From large construction sites to landscaping projects, the 320B LU is a versatile piece of machinery that can adapt to a wide range of tasks. Here are some common applications:
The CAT 320B LU is a durable, reliable, and versatile excavator that continues to be a favorite among contractors and operators worldwide. With its long undercarriage, powerful engine, and exceptional hydraulic system, the 320B LU is more than capable of handling demanding tasks on a variety of job sites. While it’s important to stay on top of maintenance and address common issues promptly, the CAT 320B LU has proven to be a long-lasting asset for those in the construction and excavation industries.
Whether you’re in need of excavation, site preparation, or heavy lifting, the 320B LU stands as a testament to Caterpillar’s commitment to quality and performance in the world of heavy machinery.

Common Maintenance Issues
While the CAT 320B LU is generally considered a durable machine, there are a few common maintenance concerns that operators should be aware of. These include:
- Hydraulic System Maintenance: Like many excavators, the 320B LU requires regular checks of the hydraulic fluid, filters, and lines. Poor hydraulic fluid levels or dirty filters can result in a loss of performance and efficiency. Operators should make it a routine to inspect the hydraulic system and change filters as needed.
- Undercarriage Wear: Since the 320B LU is designed for rough terrain, the tracks and undercarriage components are exposed to significant wear and tear. Periodic checks of the tracks, sprockets, and rollers can help prevent costly repairs down the line. Operators should also ensure that the undercarriage is free from debris, which can cause excessive wear.
- Engine Maintenance: Regular oil changes, air filter replacement, and checking for coolant leaks are essential for maintaining the engine’s longevity. The CAT 320B LU’s engine is known for its reliability, but routine maintenance is necessary to avoid performance issues.
- Electrical Components: While the electrical system on the 320B LU is generally reliable, there have been some instances where the alternator or batteries may require attention. Ensuring that the alternator is functioning properly and checking the battery’s condition can help avoid sudden electrical failures on the job site.
From large construction sites to landscaping projects, the 320B LU is a versatile piece of machinery that can adapt to a wide range of tasks. Here are some common applications:
- Excavation and Trenching: The CAT 320B LU’s long undercarriage design makes it ideal for excavation jobs that require deep digging or extended reach. Its ability to handle tough soil conditions and lift heavy loads makes it a preferred choice for contractors.
- Site Preparation: Whether it’s clearing land or grading surfaces, the 320B LU excels at site preparation tasks. The stability provided by the long undercarriage allows the excavator to operate on uneven ground with ease.
- Heavy Lifting: With the right attachments, the 320B LU can be used for lifting and moving heavy materials. Operators often use it to move large rocks, pipes, or construction debris, benefiting from its powerful hydraulic system and extended reach.
