Case 590SLE PS ext* RC, 1998: Features and Technical Specifications

Case 590SLE PS ext* RC, 1998 Technical Specifications

Introduction

Construction equipment is vital in a variety of construction projects, especially those involving excavation and material movement. One of the most crucial machines used in such projects is the backhoe loader, which typically combines the capabilities of a front-end loader and a rear-mounted digging attachment. The Case 590SLE PS ext* RC is an example of a backhoe loader that has been in production since 1998. This article provides a comprehensive analysis of its specifications and features, highlighting its strengths and weaknesses in the context of its use in construction projects.

Advantages

1. SideShift or CenterMount

The Case 590SLE PS ext* RC is designed with a SideShift or CenterMount feature that ensures it can perform efficiently in a range of worksites. The feature enables the backhoe to be mounted on either the centerline or to either side of the tractor smoothly. This capability is particularly crucial when working in tight spaces where maneuverability is limited. The operator can easily adjust the position of the excavator attachment without having to move the entire backhoe.

2. SAE dig depth (mm)

The 5420mm SAE (Society of Automotive Engineers) dig depth of the Case 590SLE PS ext* RC is a significant advantage when it comes to digging deeper trenches and excavations. This specified depth ensures that the equipment can reach the maximum depth without the need for manual labor, thereby making it an efficient and reliable machine.

3. Speeds, FR

The Case 590SLE PS ext* RC has a tremendous forward speed of 44 speeds, which makes it an extremely versatile machine. With a maximum speed of 35.3 km/h, the Backhoe Loader can move at an appropriate pace, especially as it travels from one worksite to another.

4. Loader Bucket Capacity (m3)

The Loader Bucket Capacity of the Case 590SLE PS ext* RC is one of its most significant advantages. With a capacity of 1m3, the bucket is perfect for handling various materials. Whether excavating heavy soil, rocks, or debris, the loader is reliable and efficient in handling the materials without becoming overloaded or experiencing any other issues.

5. Pump flow (lit/min)

The backhoe is equipped with a gear pump that has a flow rate of 160 liters per minute. The high flow rate ensures that the machine has sufficient power to perform substantial lifting and digging operations. The pump’s gear design is also known for its durability, making it suitable for extended periods of operation.

Disadvantages

1. Dipper breakout (kgf)

The Dipper breakout feature on the Case 590SLE PS ext* RC is a bit disappointing, with only 2410kgf of force. This limited force output can lead to difficulties when excavating deeper or harder soil. The dipper can snag and get stuck, often a frustration for operators who are hampered in their ability to get work done on time and within budget.

2. Relief valve pressure (bar)

The relief valve pressure in the Case 590SLE PS ext* RC is set at 210 bars, which isn’t as high as other models in the same category. This limitation could affect the backhoe’s ability to lift heavier loads without experiencing pressure drops. As a result, the machine may not be as efficient or reliable as other options, especially in multi-step lifting operations.

3. Ride control (Std/Opt/NA)

The Case 590SLE PS ext* RC lacks a Ride Control feature. Ride Control is typically used to reduce machine vibrations typically associated with backhoe loaders used for construction tasks. This absence can be seen as a significant downside for operators who desire a comfortable ride, particularly when working on longer projects.

4. Turn circle radius without brakes (mm)

The turn circle radius of the Case 590SLE PS ext* RC, without brakes, is significant, measuring over 10 meters. For operation in areas with limited maneuverability, this feature can be challenging to navigate, especially when precision is required. It limits the backhoe’s application, particularly when working on projects that require accuracy and tight turning radii.

5. Loading height (mm)

The Case 590SLE PS ext* RC has a limited loading height of 4190 mm. This height can be insufficient when working with materials that may require more extended reach such as unload systems or even conveyor belts. As a result, operators may have to use alternative equipment in supply systems, resulting in an inefficient and costly process.

Overall Assessment

The Case 590SLE PS ext* RC is a rugged, versatile, and reliable backhoe loader. Its SideShift or CentreMount feature ensures that the load is always stable during operation and is ideal for applications involving tight spaces. Its SAE dig depth capability and high-speed possibilities make it a powerful and efficient backhoe, capable of reaching maximum depth accurately. However, its limited Dipper breakout force can affect its performance in heavier excavations. Operators might find the Relief Valve Pressure and Ride Control facets of the backhoe limiting. Additionally, its limited loading height and the turn circle radius disadvantages points to the backhoe’s limited use cases and decreased accuracy. Its size and power make the 590SLE PS ideal for heavy-duty construction projects, but it may not be suitable for every application.

In conclusion, the Case 590SLE PS ext* RC backhoe loader is an excellent equipment capable of delivering reliable and efficient performance under specific circumstances. Customers should, however, consider the product’s advantages and limitations specific to their worksite locations before purchasing and/or operating.
