Introduction
The Case 590SL 4WD PS RC ext* is a powerful and versatile backhoe loader that is designed for heavy-duty construction and excavation work. It features a range of advanced specifications, such as a side-shift or center-mount capability, a twin ram slew system, and a 1m3 loader bucket, which are aimed at providing high efficiency, versatility, and productivity. In this article, we will analyze the advantages and disadvantages of these and other specifications to provide a comprehensive and balanced assessment of the Case 590SL 4WD PS RC ext*.
Advantages
SideShift or CenterMount
The SideShift or CenterMount capability of the Case 590SL 4WD PS RC ext* provides greater flexibility and convenience for operators. The machine can be configured to accommodate different types of workspaces, depending on the specific requirements of a job site. For instance, if a job site has limited space or the terrain is uneven, the CenterMount configuration would be more suitable as it provides greater stability and balance. In contrast, if the job site is expansive, the SideShift configuration would be more advantageous as it allows for greater maneuverability and mobility.
SAE dig depth (mm)
The SAE dig depth of the Case 590SL 4WD PS RC ext* is 6070mm. This means that the machine is capable of excavating deeper into the ground than most other backhoe loaders in its class, which is a significant advantage when it comes to digging foundation pits, trenches, and other deep holes. The increased depth also translates to greater efficiency and productivity as it enables operators to excavate more material in less time.
Reach @ ground level (mm)
The Case 590SL 4WD PS RC ext* has a reach of 7190mm at ground level. This is another advantage for excavation work as it enables operators to access hard-to-reach areas and excavate material from different angles, thereby enhancing the machine’s versatility. The longer reach also allows operators to capitalize on the machine’s high breakout force and dig deeper into the soil, which further improves productivity.
Loading height (mm)
The loading height of the Case 590SL 4WD PS RC ext* is 4190mm. This is an advantage when it comes to loading material onto trucks as it provides operators with better visibility and control over the loading process. The higher loading height also allows for greater material capacity per load, which can save time and increase efficiency.
Bucket width, min-max (mm)
The bucket width of the Case 590SL 4WD PS RC ext* ranges from 300mm to 900mm. This range provides operators with greater flexibility to adapt to different excavation and loading requirements. For instance, a narrower bucket can be used for precision work, while a wider bucket can be used for faster excavation and loading. The ability to change bucket width also allows for greater control over material handling and reduces the likelihood of damage to the machine or surrounding infrastructure.
Bucket and dipper breakout force (kgf)
The Case 590SL 4WD PS RC ext* has a bucket breakout force of 6676kgf and a dipper breakout force of 2721kgf. These high breakout forces are advantages when it comes to digging through hard soil or rock, as well as when handling heavy loads. They also enhance the machine’s digging and loading efficiency, thereby increasing productivity.
Slew System
The Case 590SL 4WD PS RC ext* features a twin ram slew system, which provides greater stability and precision when rotating the backhoe. This is an advantage when it comes to excavation work that requires high accuracy and control, such as digging trenches or laying foundation. The twin ram system also enhances the machine’s durability and reliability as it distributes the load evenly and reduces the likelihood of wear and tear on critical components.
Loader Bucket Capacity (m3)
The loader bucket capacity of the Case 590SL 4WD PS RC ext* is 1m3. This is an advantage when it comes to loading and unloading operations as it allows for greater material handling capacity and efficiency. A larger bucket also means fewer trips are required to complete a task, which reduces downtime and increases productivity.
Dump height (mm)
The dump height of the Case 590SL 4WD PS RC ext* is 2780mm. This is an advantage when it comes to unloading material as it provides operators with greater control and accuracy. The higher dump height also allows for efficient unloading onto trucks or other platforms.
Engine Power
The Case 590SL 4WD PS RC ext* is powered by a Case4T-390 engine that delivers 74kW@2200rpm. This high engine power is an advantage when it comes to heavy-duty excavation work as it provides the machine with the necessary torque and speed to dig through tough soil and rock. The powerful engine also translates to greater efficiency and productivity as it enables the machine to perform more work in less time.
Disadvantages
Pump Flow
The pump flow of the Case 590SL 4WD PS RC ext* is 161 litres per minute. This is a relatively low pump flow when compared to other backhoe loaders in its class. A low pump flow can be a disadvantage when it comes to heavy-duty excavation work as it can slow down the machine’s digging and loading operations. A slow pump flow also means that the machine may take longer to complete a task, which can reduce productivity and efficiency.
Relief Valve Pressure
The relief valve pressure of the Case 590SL 4WD PS RC ext* is 207 bar. This is a relatively high relief valve pressure when compared to other backhoe loaders in its class. A high relief valve pressure can be a disadvantage when it comes to safety, as it increases the likelihood of damage to critical components and may affect the machine’s stability.
Travel Length
The travel length of the Case 590SL 4WD PS RC ext* is 6860mm, which is relatively shorter than other backhoe loaders in its class. A shorter travel length can be a disadvantage when it comes to mobility and maneuverability, especially on uneven terrain or in confined spaces. It may also limit the machine’s ability to reach certain areas, which can reduce productivity and efficiency.
Operating Weight
The operating weight of the Case 590SL 4WD PS RC ext* is 7948kg. This is a relatively heavy machine, which can be a disadvantage when it comes to transport and storage. The heavy weight may also impact the machine’s maneuverability and mobility, especially on soft or weak terrain, which may limit its effectiveness in certain job sites.
Ride control
The Ride control feature of the Case 590SL 4WD PS RC ext* is standard. Ride control is a system that smooths the ride of the machine and reduces shock load on the structure during travel over rough or uneven surfaces. However, in some instances, Ride control may not be applicable, especially when it comes to precision excavation or when the machine is required to operate in tight spaces. In these instances, the Ride control feature may be a disadvantage as it can limit the machine’s precision and control.
Overall Assessment
The Case 590SL 4WD PS RC ext* is a powerful and versatile backhoe loader that is designed for heavy-duty excavation and construction work. Its advanced features, such as the SideShift or CenterMount capability, the long reach and SAE dig depth, and the high bucket and dipper breakout force provide significant advantages when it comes to productivity, efficiency, and versatility. However, some features, such as the low pump flow, high relief valve pressure, shorter travel length, heavy
