JCB 4C Turbo, 1987 Technical Specifications

Introduction

The JCB 4C Turbo was introduced in 1987 as a versatile and efficient backhoe loader for various applications. It offered a range of features and specifications such as SideShift or CenterMount, SAE dig depth of 5440mm, loader bucket capacity of 1.1m3, and engine power of 61kW@2200rpm, among others. This article will provide a comprehensive analysis of the advantages and disadvantages of these features and specifications and their practical applications.

SideShift or CenterMount

One of the key features of the JCB 4C Turbo is the option of SideShift or CenterMount. This feature allows the operator to select the optimal position of the backhoe attachment relative to the frame of the loader for better stability, reach, and digging performance. The SideShift option allows the backhoe to be offset to either side of the centerline of the loader, while the CenterMount option maintains the backhoe in the centerline.

Advantages of the SideShift or CenterMount feature include improved versatility, ease of use, and safety. With the SideShift option, the operator can work in narrow or confined spaces without worrying about the loader being out of balance or damaging its surroundings. The CenterMount option, on the other hand, offers more stability and control when working on uneven or sloping terrain. Additionally, the SideShift or CenterMount feature reduces operator fatigue and increases productivity by enabling quick and precise adjustments to the backhoe position.

Disadvantages of the SideShift or CenterMount feature include added complexity and maintenance requirements, as well as potential reduced visibility for the operator. The SideShift or CenterMount mechanism adds weight and moving parts to the loader, which may affect its overall durability and reliability. Also, the operator may need to rely on mirrors or cameras to compensate for blind spots created by the shifted backhoe position.

SAE dig depth and Reach at Ground Level

The SAE dig depth and Reach at Ground Level specifications of the JCB 4C Turbo indicate the maximum distance that the backhoe can excavate below ground level and horizontally from the tip of the bucket. The SAE standards ensure consistency and comparability of these measurements across different equipment manufacturers.

Advantages of the SAE dig depth and Reach at Ground Level specifications include increased efficiency, precision, and flexibility in digging operations. The JCB 4C Turbo can reach deeper and farther than many other backhoe loaders, allowing it to tackle a wider range of excavation tasks with fewer passes and less time. This translates into lower fuel consumption, reduced wear and tear on the equipment, and higher productivity. Moreover, the SAE standards provide a reliable basis for comparing the performance of the JCB 4C Turbo with other backhoe loaders in the market.

Disadvantages of the SAE dig depth and Reach at Ground Level specifications include less maneuverability in tight spaces or around obstacles. The maximum reach and depth may not always be necessary or practical for certain jobs, such as digging trenches close to walls or buildings, in which case a smaller or more agile backhoe may be preferable. Also, the SAE standards have some limitations in representing the actual digging conditions, such as the hardness of the soil, the angle of the bucket, or the operator’s skill.

Loading height and Bucket width

The Loading height and Bucket width specifications of the JCB 4C Turbo refer to the maximum height at which the loader can lift a load and the range of bucket sizes that can be attached to the backhoe, respectively. These specifications determine the capacity and loading efficiency of the loader.

Advantages of the Loading height and Bucket width specifications include higher capacity, better accessibility, and versatility in handling different materials and loads. The JCB 4C Turbo can lift and carry heavy loads of various sizes and shapes, thanks to its high loading height and wide range of bucket widths. This allows the operator to load and unload materials more quickly and safely, saving time and reducing the risk of damage or accidents. Furthermore, the Loading height and Bucket width specifications can be adjusted according to the specific needs of each job, making the JCB 4C Turbo suitable for a wide range of applications, such as construction, agriculture, or landscaping.

Disadvantages of the Loading height and Bucket width specifications include potential instability or overload if the materials or loads exceed the recommended limits. The operator must ensure that the loader remains balanced and secure when lifting or carrying heavy or uneven loads, which may require additional tools or equipment. Moreover, the Loading height and Bucket width specifications may not be sufficient or optimal for specialized or unique tasks that require specific attachments or modifications.

Bucket breakout and Dipper breakout

The Bucket breakout and Dipper breakout specifications of the JCB 4C Turbo indicate the force that the bucket and dipper can apply when digging or prying materials. These specifications depend on the hydraulic pressure and flow of the loader’s pump system.

Advantages of the Bucket breakout and Dipper breakout specifications include faster digging, better penetration, and greater efficiency in handling tough or compacted soils or rocks. The JCB 4C Turbo can easily break and lift soil, gravel, or debris that would be hard or impossible to move with hand tools or less powerful equipment. This translates into reduced labor costs, increased precision, and higher productivity. Furthermore, the Bucket breakout and Dipper breakout specifications can be adjusted according to the soil type or digging depth, providing more control and adaptability for the operator.

Disadvantages of the Bucket breakout and Dipper breakout specifications include potential damage to the equipment or the environment if the force is applied improperly or excessively. The operator must be cautious when using the Bucket breakout and Dipper breakout feature to avoid overexcavation, overloading, or impacting nearby structures or utilities. Also, the Bucket breakout and Dipper breakout specifications may not be sufficient or optimal for delicate or sensitive digging operations that require minimal disturbance or precision, such as archaeological or ecological studies.

Engine and Transmission

The Engine and Transmission of the JCB 4C Turbo play a crucial role in powering and controlling the loader’s performance. The engine is a Perkins T4.236 model that produces 61kW@2200rpm, while the transmission is a PS TC type that offers 2WD/4WD drive and 42 speeds, with a maximum speed of 32km/h.

Advantages of the Engine and Transmission specifications include high power, efficiency, and durability. The Perkins engine is widely recognized for its reliability, fuel economy, and low emissions, making it a suitable choice for heavy-duty applications. The PS TC transmission provides smooth and precise shifting, as well as a wide range of speeds and gears that can adapt to different driving and working conditions. This allows the operator to maintain optimal traction, speed, and torque, reducing slippage, wear, and fatigue. Moreover, the Engine and Transmission specifications are compatible with various types of fuel and lubricants, offering more flexibility and convenience for the operator.

Disadvantages of the Engine and Transmission specifications include potentially high maintenance and repair costs if the equipment is not properly maintained or serviced. The engine and transmission require regular inspections, lubrication, and replacement of parts to ensure optimal performance and lifespan. Also, the Engine and Transmission specifications may not be suitable or efficient for certain jobs that require more specialized or custom engines or transmissions, such as marine or industrial applications.

Overall Assessment

In conclusion, the JCB 4C Turbo offers a range of features and specifications that can provide significant advantages and challenges depending on the application and the operator’s skill and experience. The SideShift or CenterMount option can increase versatility and productivity but may
