Understanding the Shovel Performance Ratings
The shovel or bucket is one of the most critical components of a wheel loader. The performance of the shovel, including its capacity to carry material, loading speed, and lifting height, directly impacts the loader’s productivity on a job site.
- Bucket Capacity:
The Volvo L120B typically comes with bucket capacities ranging between 2.0 to 3.5 cubic yards, depending on the configuration and the attachment used. This capacity is important for operators because it determines how much material can be moved per cycle. A larger bucket capacity enables more material to be moved, reducing the number of trips needed to fill trucks or move material, thus improving overall efficiency.
Tip: Selecting the right bucket size for the job can have a major impact on productivity. For tasks like loading loose materials or snow, a larger bucket might be ideal, while smaller or denser materials could be more efficiently handled with a smaller capacity.
- Lifting and Dumping Heights:
The lifting height of the Volvo L120B’s bucket is another important performance metric. The loader has a lift height of around 3.5 meters (approximately 11.5 feet), which is typical for this class of machine. This height allows the loader to dump material into standard-height trucks or stockpiles without requiring excessive maneuvering.
Consideration: If the loader is often used for loading material into high-sided trucks, a higher lift reach may be necessary. Similarly, depending on the job site, the tipping angle may also affect how efficiently the loader can unload its bucket.
- Breakout Force:
The breakout force refers to the force exerted by the bucket when it is used to break into a pile of material. For the Volvo L120B, the breakout force is strong enough to handle most types of materials, including aggregate, sand, and soil. This makes the loader well-suited for heavy-duty tasks such as stockpiling materials or loading trucks in quarry environments.
Tip: To optimize the breakout force, ensure the bucket is always maintained in good condition. Dull or damaged edges can reduce efficiency and require more power to achieve the same results.
- Engine Specifications:
The Volvo L120B is equipped with a powerful 6-cylinder, turbocharged engine that delivers approximately 145 horsepower. This engine size allows the loader to operate efficiently across a variety of tasks while maintaining optimal fuel consumption.
Fuel Efficiency Consideration: Operators should be mindful of fuel efficiency, particularly when the loader is being used for extended periods. Heavy equipment like the L120B tends to consume significant amounts of fuel, especially during high-load operations. However, modern loaders like the L120B are designed with fuel-saving technologies that help optimize consumption while maintaining high productivity levels.
- Variable-Speed Drive System:
The variable-speed drive system of the L120B adjusts the speed of the loader according to the load and terrain conditions. This system helps reduce fuel consumption while providing optimal power when needed. During lighter load operations, the system runs at lower speeds to save fuel, whereas under heavy load conditions, it adjusts to higher speeds to maximize power delivery.
Tip: Operators should adjust the throttle and speed settings based on the task at hand. By matching the machine’s performance to the workload, fuel efficiency can be improved while maintaining productivity.
- Hydraulic Power:
The hydraulic system of the Volvo L120B is a key contributor to its shovel performance. The loader features a strong hydraulic system that provides ample lifting and tilting force to perform operations like loading, lifting, and dumping with ease. The hydraulic pump delivers high flow rates, ensuring smooth and quick bucket movement.
Hydraulic Tip: Regular maintenance of the hydraulic system, such as checking fluid levels and replacing filters, is essential to maintain optimal performance and avoid costly repairs down the line.
- Cycle Times and Efficiency:
The cycle time of a loader refers to the time it takes to complete a full operation cycle — from scooping material into the bucket to dumping it into a truck or pile. For the Volvo L120B, cycle times are relatively quick for a wheel loader in its class, especially when using the right attachments and settings.
Consideration: Optimizing cycle times involves operator skill and machine settings. Experienced operators can minimize downtime between cycles, thus boosting overall productivity.
- Maintenance Schedule:
Proper maintenance is vital to the longevity and performance of the Volvo L120B. Routine tasks such as checking fluid levels, cleaning air filters, and inspecting the bucket and hydraulic lines help prevent costly breakdowns.
Story: One operator shared that they neglected to replace a worn hydraulic hose on their L120B. This led to a hydraulic fluid leak that caused a decrease in performance, eventually leading to costly repairs. The key lesson here was the importance of regular maintenance to ensure machine longevity and efficient operation.
- Longevity of Components:
With regular care, the Volvo L120B is built to last, even under harsh working conditions. Components like the bucket, tires, and engine should be replaced only when necessary. Properly maintaining these parts ensures that the loader will continue to perform optimally over its lifespan.
Despite its high performance, the Volvo L120B does have a few common issues that operators should be aware of. Some of these include:
- Hydraulic System Leaks: Due to heavy use, hydraulic systems are prone to leaks, which can impact performance. Regular inspections of the hydraulic hoses and seals are necessary.
- Bucket Wear and Tear: The bucket is one of the most used components on the loader and can wear out over time. Regularly checking and replacing the cutting edge can prolong the life of the bucket.
- Electrical Problems: Electrical issues, while not overly common, can occur and may affect the loader's performance. It’s essential to check the electrical connections and the battery regularly to avoid malfunctions.
The Volvo L120B wheel loader is a well-rounded, high-performance machine that offers impressive shovel capacity, fuel efficiency, and hydraulic power. By understanding its key performance metrics, operators can maximize productivity while minimizing operational costs.
Regular maintenance, attention to detail, and efficient use of the loader’s features will ensure that the Volvo L120B continues to provide reliable service throughout its lifespan. Whether you're working in construction, mining, or any other industry requiring heavy lifting and material handling, the L120B remains a strong contender for demanding tasks.
