Case 680H, 1985 Technical Specifications

The Case 680H: Advantages and Disadvantages of Technical Specifications

Introduction

The Case 680H is a versatile backhoe loader designed to tackle a variety of construction tasks, from digging and trenching to loading and lifting. Its technical specifications, such as its SAE dig depth and loader bucket capacity, determine its capabilities and limitations. In this article, we will analyze both the advantages and disadvantages of the relevant features and specifications of the Case 680H, providing real-world examples to illustrate their practical applications.

Advantages of Technical Specifications

SIDEshift and CenterMount

One advantage of the Case 680H is its choice of SideShift or CenterMount configurations for its backhoe attachment. This allows the operator to choose the attachment’s position depending on the task at hand, improving the machine’s overall flexibility. For instance, SideShift provides easy access to dig around obstacles, while CenterMount delivers increased stability when digging deeper.

SAE Dig Depth and Reach at Ground Level

The SAE dig depth of 5,030 mm and reach at ground level of 7,160 mm are impressive technical specifications that allow the Case 680H to reach deep and wide, making it suitable for foundational work and excavation in urban environments. The machine can dig trenches, remove rocks and soil, and level terrain in a single pass, reducing the time and effort needed to complete the job.

Loader Bucket Capacity

The loader bucket capacity of 0.97 m3 is another advantage that makes the Case 680H a suitable choice for loading and unloading large amounts of material, such as gravel, sand, and debris, at construction sites. This capacity allows the machine to transport more goods with each trip, saving the operator time and fuel costs.

Dipper and Bucket Breakout Force

The dipper breakout force of 3,959 kgf and bucket breakout force of 5,916 kgf enhance the machine’s digging and lifting capabilities. The breakout force measures the amount of force that the excavator can exert to break up or lift substances. Therefore, these forces allow the machine to handle more massive rocks, concrete blocks, and other heavy materials with ease.

Pump Flow and Relief Valve Pressure

The pump flow of 97 lit/min and relief valve pressure of 137.9 bar are beneficial features as the machine can operate smoothly and efficiently. The pump flow is responsible for the backhoe’s hydraulic performance, ensuring it has enough power to dig, lift, and carry objects consistently. Also, the relief valve pressure keeps the system safe, preventing it from exceeding a specific limit and risking any damage to the machine.

Disadvantages of Technical Specifications

2WD Drive

One of the drawbacks of the Case 680H is its 2WD drive, which can impact its traction and stability, especially on uneven terrain or when lifting heavy loads. The machine’s inability to handle all-terrain may limit its application in areas with challenging landscapes, reducing its overall versatility.

Max Speed and PS TC Transmission

With a maximum speed of 31 km/h and a PS TC transmission type, the Case 680H may not be the fastest machine on the construction site. While speed may not be the primary consideration for backhoes, some time-critical tasks, such as emergency repairs, require prompt mobilization of resources. Additionally, the PS TC transmission uses a torque converter, which may affect fuel efficiency and result in higher fuel consumption, increasing the operating cost for the operator.

Limited ride control option

The Case 680H does not offer ride control as a standard or optional feature, making it difficult for the operator to maneuver the machine when driving over rough terrain. The lack of ride control can cause a bumpy and uncomfortable ride, leading to operator fatigue and increasing the risk of accidents.

Real-World Examples

Advantages

Suppose a construction site, located in a congested urban area, needs to create a foundation for a new residential complex. The Case 680H is an ideal choice for the job due to its ability to reach deep and wide trenches, as well as delivering a breakout force that can handle the hard, rocky soil within a single pass. This leads to reduced project time and cost.

In another example, a construction company that needs to transport large amounts of soil, sand, and gravel to and from the work site can benefit from the Case 680H’s loader bucket’s high capacity. With this feature, the machine can transport more material in fewer cycles, hence reducing fuel consumption and machine wear and tear.

Disadvantages

Suppose a construction project requires the excavation of a steep hillside terrain. In this case, the Case 680H’s 2WD drive may limit its traction and cause the machine to slide or lose control while digging. This increases the time and effort needed to complete the project, leading to higher costs and potential delays.

In another example, suppose a company needs to carry out emergency repairs on a busy road using a backhoe. The Case 680H’s maximum speed of 31 km/h and PS TC transmission type may make it less responsive than other machines, causing delays and traffic congestion.

Overall Assessment

The Case 680H is a versatile backhoe loader with a variety of technical features. The advantages, such as the SAE dig depth, dipper and bucket breakout force, and loader bucket capacity, make it suitable for a wide range of construction projects. The disadvantages, such as the 2WD drive, max speed, and lack of ride control, may limit its application in some environments, but overall the advantages outweigh the disadvantages. In conclusion, the Case 680H is an excellent investment for construction companies that require a robust, versatile and efficient backhoe loader.
