JCB 4C, 2003 Technical Specifications

Introduction

When it comes to construction equipment, the JCB 4C model is one of the most sought-after pieces of machinery. It is known for its excellent performance, stability, and reliability. It offers a range of features and specifications that can make construction work much easier, faster, and more efficient. However, as with any piece of equipment, there are both advantages and disadvantages to consider.

SideShift or CenterMount

One of the most significant advantages of the JCB 4C is its ability to be used as a SideShift or CenterMount. This versatile feature allows the operator to switch between the two based on the specific application they are working on. This means that the machine can move laterally, providing greater control, precision, and maneuverability.

SAE dig depth (mm)

Another advantage of the JCB 4C is its SAE dig depth of 6140mm. This means that it can dig deeper than many other machines in its class, making it suitable for a range of applications, including excavation, demolition, and material handling.

Reach @ ground level (mm)

In addition to its dig depth, the JCB 4C also has a reach of 7100mm at ground level. This offers an increased working area where operators can work with ease and in comfort. With this feature, operators can work comfortably without having to maneuver the machine too much, which can significantly reduce operator fatigue and improve overall productivity.

Loading height (mm)

One of the disadvantages of the JCB 4C, however, is that it does not have a loading height listed in its technical specifications. This can be a concern when it comes to loading materials onto a truck or a trailer, as it may be challenging to reach the required height if the machine does not have the necessary features.

Bucket width, min-max (mm)

The JCB 4C offers flexibility in bucket width as it can be adjusted to a minimum of 230mm and a maximum of 1830mm. This allows for various materials to be loaded and transported with ease. The adjustable bucket width also allows for more precise handling of different materials, reducing the risk of mishandling and, in turn, increasing safety.

Bucket breakout and dipper breakout (kgf)

The JCB 4C comes with excellent breakout forces for both the bucket and the dipper. The bucket has a breakout force of 6705kgf, while the dipper has a force of 3300kgs. The high breakout forces make it easier to dig through tough materials, providing greater productivity, and reducing the risk of stress or strain on the machine. With these features, the JCB 4C can lift, handle, and transport heavy materials without the need for several attachments.

Slew System

Another advantage of the JCB 4C is its twin ram Slew System. The twin ram offers smoother and more precise operation, reducing wear and tear, and extending the machine’s life. An advantage of the twin ram system is that it can provide more control in tight spaces and when working around obstacles, as it allows for a more gradual degree of movement. This feature makes it easier to carry out delicate work such as grading or landscaping and reduces the risk of tearing up the ground.

Loader Bucket Capacity (m3) and Dump height (mm)

The JCB 4C offers a loader bucket capacity of 1.1m3, which is ideal for loading materials such as gravel, sand, and dirt. The dump height of 2740mm is also advantageous, as it allows for dumping materials over high walls, into trucks, or directly onto the ground. The high dump height also ensures that the machine can handle materials with ease, increasing productivity on construction sites where materials need to be moved from one location to another quickly.

Engine Make & Model

The JCB 4C’s Perkins 1004.4THR engine is known for its reliability, lighter weight, and better fuel efficiency than previous engine models. This feature makes it ideal for long hours of operation, where fuel consumption is a significant concern. In addition, the engine’s power output of 74.6kW@2200rpm provides enough power to handle demanding applications such as digging and excavation with ease.

Speeds, FR and Maximum speed (km/h)

The JCB 4C’s two-wheel and four-wheel driving options allow it to operate on different terrains, making it adaptable to different work conditions. With 64 speeds, the machine can move at various speeds depending on the application and the operator’s preference. Its maximum speed of 41km/h is a significant advantage while hauling materials from one location to another, significantly increasing overall productivity.

Transmission type

A disadvantage of the JCB 4C is its Full PS/Opt auto transmission. Although it offers versatility, it can be challenging to use for inexperienced operators. The machine’s transmission requires a level of skill and finesse to use effectively, and if used poorly, it can cause undue stress and damage to the machine.

Ride control

The JCB 4C also offers ride control as an optional feature. This feature provides greater comfort to operators when working on uneven terrain, reducing jolting and shaking, and improving the operator’s overall experience. However, the additional cost of ride control may be a downside for construction companies working on a tight budget.

Overall Assessment

The JCB 4C is a versatile machine with several advantages and disadvantages to consider. Its SideShift or CenterMount capabilities, SAE dig depth, and bucket capacity make it a reliable and efficient machine for construction projects, while its twin ram Slewing system, high dump height, and breakout forces provide greater productivity, precision, and safety. However, its lack of loading height specification, transmission type, and optional ride control feature may be concerning for some operators. Overall, the JCB 4C remains a popular choice for many construction companies due to its stability, reliability, and excellent overall performance.
