Case 590, 1993 Technical Specifications

Introduction

The Case 590 backhoe loader is designed for the demanding construction industry. It is equipped with features and specifications that make it versatile and powerful. In this article, we will analyze both the advantages and disadvantages of the relevant features and specifications of the Case 590 backhoe loader in detail. We will discuss each specification and analyze its real-world applications.

SideShift or CenterMount

The Case 590 backhoe loader comes in two variants: SideShift and CenterMount. The SideShift variant is ideal for operations where the worker needs to operate in tight spaces, whereas the CenterMount variant is suitable for larger work areas. The SideShift feature allows the operator to move the backhoe to the side, making it easier to operate in confined spaces, such as urban areas or tight job sites. The CenterMount variant provides greater stability and power, making it suitable for heavy-duty work such as excavation and demolition work.

SAE dig depth (mm)

The SAE dig depth of the 590 model is 4720mm, which is very deep, making it suitable for deep excavations. The deep digging capability of the 590 makes it suitable for building foundations, digging manholes and trenches, and other deep excavation activities.

Reach @ ground level (mm)

The reach of the 590 at ground level is 7060mm, which is a substantial distance. The long reach feature allows the operator to work on various levels alongside buildings, over fences, and other obstacles without having to reposition the backhoe. The long reach makes the backhoe more versatile in situations where a short reach would make it difficult to perform certain tasks.

Loading height (mm)

The loading height of the 590 is 3480mm, which makes it ideal for loading materials onto trucks and trailers. The high loading feature makes it easier to load materials such as gravel, dirt, sand, and other materials from steep slopes. It also enables the operator to load materials from high platforms or heights, such as bridge decks or construction sites.

Bucket width, min-max (mm)

The bucket width of the 590 ranges from 305-914mm. The variable bucket width feature of the 590 makes it versatile and suitable for a wide range of excavation operations. The narrow bucket width is ideal for digging trenches and ditches, whereas the wide bucket width is suitable for loading materials and bulk excavation activities. The varying bucket width makes the backhoe more adaptable to a range of tasks.

Bucket breakout (kgf)

The bucket breakout of the 590 is 5227kgf, which is high. The high bucket breakout feature allows the backhoe to dig through compacted soil, rock, and other challenging materials with ease. It also makes the backhoe more efficient in excavation operations by enabling it to dig more material per scoop. However, the high bucket breakout could be damaging to sensitive underground utilities such as gas and water lines.

Dipper breakout (kgf)

The dipper breakout of the 590 is 3272kgf, which is lower than the bucket breakout. The lower dipper breakout prevents the backhoe from causing damage to sensitive underground utilities when digging. However, the low dipper breakout could result in the backhoe being less effective when digging through tough materials, such as rock.

Slew System

The slew system of the 590 is cylinder-based. The hydraulic impact of the cylinders provides solid protection to the bearings and other parts of the slew, making it less prone to wear and tear. The cylinder-based slew system also ensures smooth and efficient operation and requires less maintenance. However, the cylinder-based slew system could be more expensive to repair than a gear-based slew system.

Loader Bucket Capacity (m3)

The loader bucket capacity of the 590 is 0.96m3, which is high. The high loader bucket capacity makes it easier for the backhoe to load materials onto trucks and trailers. The large capacity also makes it more efficient to move materials such as sand, stone, and gravel when working on construction sites. However, the high loader bucket capacity could be too large for small-scale operations, making it difficult to maneuver and operate in tight spaces.

Dump height (mm)

The dump height of the 590 is 2790mm. The high dump height allows the backhoe to dump materials onto high-sided trucks and trailers with ease. The high dump height also makes it more convenient to dump material into large piles, making it more efficient to organize materials on construction sites. The high dump height feature saves the operator time and reduces the effort required to move materials. However, the high dump height could be a problem in low-height areas, such as underground buildings and tunnels.

Engine Make & Model

The engine make and model of the 590 is a Case 4T390. The Case 4T390 is a reliable and efficient engine that delivers powerful performance. The engine is designed to be low maintenance and long-lasting. It is ideal for heavy-duty operations such as excavation, demolition work, and loading. However, the Case 4T390 engine could be noisy and produce high emissions levels.

Engine power (kW@rpm)

The engine power of the 590 is 64kW@2200rpm. The engine power is high enough to provide the backhoe with the necessary power required for various heavy-duty tasks. The high engine power also allows the backhoe to work in challenging environments, such as steep slopes and uneven terrain. The high engine power feature makes the backhoe more efficient and reduces the amount of time required to complete tasks.

Engine displacement (lit)

The engine displacement of the 590 is 3.9liters. The engine displacement correlates directly with the engine power, providing enough power to run the backhoe’s hydraulic systems and motors. The engine displacement also ensures that there is sufficient power to load and move materials. However, the engine displacement can affect fuel economy, resulting in higher fuel consumption costs.

Number of cylinders

The 590 backhoe loader has four cylinders. The four-cylinder engine makes the backhoe more efficient than other backhoes having fewer cylinders. Additionally, the four-cylinder engine provides the backhoe with the power and torque needed to work on challenging terrains. However, the four-cylinder engine may produce more emissions than a smaller engine with fewer cylinders.

Pump type

The 590 backhoe loader has two gear pumps. The gear pumps in the backhoe provide the hydraulic pressure needed to run the backhoe’s movement and actions. The two pumps make the backhoe more efficient and provide smoother and more controlled movement. However, two pumps can make the backhoe operation more complicated and may require more maintenance.

Pump flow (lit/min)

The pump flow of the 590 backhoe loader is 155lit/min. The high pump flow enables the backhoe to lift and move more material per minute, making it more efficient. It also makes it easier to operate the backhoe when digging through hard or rocky terrain. However, the high pump flow could increase fuel consumption and result in higher fuel costs.
