Introduction
The Case 590 is a versatile backhoe loader that offers high levels of performance and flexibility, making it suitable for a wide range of applications. Its features and specifications provide a balanced mix of advantages and disadvantages, which this analysis aims to explore in greater detail.
SideShift or CenterMount
The Case 590 is available in both SideShift and CenterMount configurations, each with its own advantages. The SideShift configuration provides better visibility and maneuverability in tight spaces, making it ideal for urban construction and maintenance projects. However, the CenterMount configuration offers greater digging power and stability, making it a better choice for heavy-duty excavation work.
SAE dig depth
The SAE dig depth of 4720mm is a significant advantage of the Case 590, allowing it to reach deeper than many of its competitors. This is particularly useful for excavating deep foundations or underground utilities. However, the deeper dig depth also means that the machine is taller, which can be a disadvantage in low-clearance areas.
Reach @ ground level
The 7060mm reach at ground level is another advantage of the Case 590, allowing it to access areas that are difficult to reach with other backhoe loaders. This is especially useful for working on slopes or uneven terrain. However, the longer reach also means that the machine has a wider turning radius, which can be a disadvantage in confined spaces.
Loading height
The 3480mm loading height of the Case 590 is a disadvantage compared to some of its competitors, as it limits the machine’s ability to load materials onto high-sided trucks or containers. This can be a problem on sites where there is limited space for stockpiling or material handling.
Bucket width
The bucket width of the Case 590 is a versatile feature, with a range of 305-914mm. This allows the machine to handle a variety of materials, from fine-grained soil to large boulders. However, the narrowest width of 305mm may be too small for some applications, such as loading bulky materials, while the widest width of 914mm may be too large for precision work.
Bucket and dipper breakout
The bucket and dipper breakout of the Case 590 are both advantages, with 5116kgf and 3203kgf respectively. This means that the machine can easily break through hard materials such as rock or concrete, making it an excellent choice for demolition projects. However, the high breakout forces also mean that the machine requires careful handling to avoid damage to structures or injury to personnel.
Slew System
The Cylinder slew system of the Case 590 is a reliable and durable mechanism, with low maintenance requirements. However, it may be less precise than more advanced systems, which can be a disadvantage in applications that require high levels of accuracy.
Loader Bucket Capacity and Dump height
The loader bucket capacity of 0.95m3 and dump height of 2690mm are both advantages of the Case 590, as they allow the machine to handle large volumes of material quickly and efficiently. However, the high dump height can be a disadvantage in low-clearance areas, and the large bucket capacity may be excessive for some applications, leading to wasted time and fuel.
Engine Make & Model, Power and Displacement
The Case 4T390 engine is a reliable and efficient power source, with 64kW@2200rpm and a displacement of 3.9 liters. These specifications provide a good balance of power and fuel efficiency, making the machine suitable for a variety of applications. However, the engine may lack the power required for heavy-duty work, and the displacement may be too large for some operators’ needs.
Number of Cylinders, Pump Type, and Flow
The 4-cylinder engine of the Case 590 is fuel-efficient and reliable, with low maintenance requirements. The 2xGear pump type provides consistent and reliable hydraulic power, with a flow of 155 liters per minute. However, the pump flow may be insufficient for some applications, requiring the operator to run the machine at higher rpm, which can lead to increased fuel consumption and engine wear.
Relief Valve Pressure and Transmission Type
The relief valve pressure of 190 bar is an advantage of the Case 590, ensuring that the machine can operate safely and efficiently under high loads. The PS TC transmission type is also an advantage, providing efficient power transfer and smooth shifting. However, the transmission may be less responsive than more advanced systems, which can be a disadvantage in applications that require fast and precise movement.
Drive, Speeds, and Maximum Speed
The 2WD/4WD drive of the Case 590 is a versatile feature, allowing the machine to be used in a wide range of conditions. The 44 forward/reverse speeds are also an advantage, providing fine control over the machine’s movement. The maximum speed of 40 km/h is a moderate speed, suitable for most applications. However, the machine may lack the speed required for fast moving operations, such as road construction.
Ride Control and Travel Length/Height
The absence of ride control in the Case 590 is a disadvantage compared to some of its competitors, as it can lead to decreased operator comfort and increased wear on components. The travel length of 7160mm and travel height of 3500mm are both advantages, allowing the machine to cover long distances quickly and access areas that are difficult to reach with other backhoe loaders.
Width and Turn Circle Radius
The width of the Case 590 is a moderate 2220mm, making it suitable for most applications. However, the turn circle radius of 7900mm without brakes is a disadvantage, as it limits the machine’s ability to maneuver in tight spaces. This can be problematic on sites with limited space or obstacles.
Operating Weight
The operating weight of 7355kg is an advantage of the Case 590, as it provides stability and prevents the machine from tipping over during heavy-duty work. However, the weight may be a disadvantage in some applications, such as working on unstable terrain, where lighter machines may be more suitable.
Overall Assessment
The Case 590 is a versatile and reliable backhoe loader, with a balanced mix of features and specifications that provide both advantages and disadvantages. Its deep dig depth, long reach, and strong breakout forces make it well-suited for a variety of excavation and demolition applications. However, its moderate speed and turning radius, as well as its high loading height and operating weight, may limit its effectiveness in other areas. Overall, the Case 590 is a good choice for operators looking for a machine with solid performance and flexibility.
