Introduction
The JCB 2CX Extradig is a backhoe loader designed for various construction applications. Its features and specifications are essential to understanding the machine’s capabilities. Therefore, this article discusses the advantages and disadvantages of relevant features and specifications of the JCB 2CX Extradig.
Advantages and Disadvantages
SideShift or CenterMount
One of the most significant advantages of the JCB 2CX Extradig is the SideShift or CenterMount feature. This feature provides flexibility in positioning the machine while performing various tasks. SideShift allows the backhoe to move horizontally without changing its position, while CenterMount enables the machine to swing about its center axis, giving the user more control over the work area—this feature’s disadvantage is that it may require additional training and skill for operators to use effectively.
SAE Dig Depth
The SAE dig depth of 3500mm is useful for excavating deep trenches and holes. This feature makes the JCB 2CX Extradig suitable for large-scale construction projects. However, depending on the project requirements, the machine may not be ideal for shallow digging or surface work.
Reach @ Ground Level
The JCB 2CX Extradig has a reach of 5400mm at ground level, making it suitable for handling large loads, digging deep trenches, and excavating materials from hard-to-reach areas. However, the machine’s reach may also pose a disadvantage if used in confined spaces or narrow construction sites where maneuverability is necessary.
Loading Height
The loading height of the JCB 2CX Extradig is 3630mm, which is advantageous for loading heavy materials onto trucks or containers. However, this feature may be a disadvantage in low ceiling areas, making the machine unsuitable for indoor construction projects.
Bucket Width, Min-Max
The bucket width of the JCB 2CX Extradig, which ranges from 230-750mm, provides flexibility in excavation and earthmoving tasks. This feature makes the machine suitable for various construction projects and increases productivity. However, the machine’s bucket width may also pose a disadvantage in tight spaces or areas that require precision work, making the machine less effective in such conditions.
Bucket Breakout and Dipper Breakout
The JCB 2CX Extradig’s bucket and dipper breakout forces are 3400kgf and 1800kgf, respectively. These forces make the machine suitable for a wide range of excavation and earthmoving tasks. However, these forces may also pose a disadvantage if used in delicate construction projects where precision is essential. The high breakout forces may damage structures or delicate ground conditions.
Slew System
The machine’s Twin Ram Slew System is a significant advantage as it increases the machine’s stability while performing various tasks. This system ensures that the machine can handle heavy loads and excavate materials without tipping over. However, this feature also poses a disadvantage as it increases the machine’s weight, making it difficult to transport to remote areas or narrow construction sites.
Loader Bucket Capacity and Dump height
The JCB 2CX Extradig has a loader bucket capacity of 0.6m3 and a dump height of 2520mm. This feature enables the machine to handle large loads effectively and increases productivity. However, the machine’s loader bucket capacity may also pose a disadvantage in small-scale construction projects where small amounts of materials need to be moved around.
Engine Make & Model, Power and Pump Type and Flow
The JCB 2CX Extradig is powered by a Perkins 1000.4 engine, which provides a power output of 44kW at 2000rpm. This power output makes it suitable for various construction projects that require high power. The machine’s gear pump type and flow rate of 58lit/min are also advantageous as they ensure that the machine can handle heavy loads with ease. However, these features require regular maintenance, and their efficiency may decrease over time if not maintained correctly.
Transmission Type and Drive
The JCB 2CX Extradig has a power shuttle transmission type that enables the machine to change gears smoothly and efficiently. This feature increases the machine’s maneuverability, making it suitable for various construction projects, including road construction. The machine’s 4WD drive is also advantageous, ensuring that it can handle rough terrain and harsh weather conditions. However, the machine’s transmission type may also pose a disadvantage as it requires regular maintenance, increasing the machine’s maintenance costs over time.
Speeds and Maximum Speed
The JCB 2CX Extradig has forward speeds of 4 and reverse speeds of 4, providing the machine with the necessary flexibility to adapt to various terrain types. The machine’s maximum speed of 32km/h also makes it suitable for transport between construction sites. However, the machine’s speed may pose a disadvantage in confined spaces or narrow construction sites, where slow and precise movements are necessary.
Ride Control
The JCB 2CX Extradig does not have a ride control feature, which may be a disadvantage. Ride control features increase operator comfort and improve the machine’s stability while operating on uneven terrain. Without ride control, the machine’s operator may find it challenging to maintain control of the machine, reducing its productivity.
Travel Length, Height, Width, and Turn Circle Radius without Brakes
The JCB 2CX Extradig has a travel length of 4880mm, a travel height of 2670mm, and a width of 1850mm. These features make the machine suitable for transport between construction sites. However, the machine’s turn circle radius without brakes of 3030mm may pose a disadvantage, making it difficult to navigate in confined spaces or narrow construction sites.
Operating Weight and Model
The JCB 2CX Extradig’s operating weight of 5240kg is an advantage as it ensures that the machine is stable while performing various tasks. The machine’s model is also advantageous as it is suitable for various construction projects, including road construction, excavation, and earthmoving. However, the machine’s operating weight may also be a disadvantage as it makes it difficult to transport to remote areas or narrow construction sites.
Real-World Examples
An excellent example of the JCB 2CX Extradig’s advantages and disadvantages is its usage in road construction projects. The machine’s high breakout forces, power, and stability make it suitable for breaking up the existing road surface and excavating materials from hard-to-reach areas. However, the machine’s weight may pose a challenge if the project requires transporting the machine to remote areas or narrow construction sites.
The JCB 2CX Extradig is also useful in large-scale construction projects, where its bucket width and dig depth come in handy. The machine can excavate deep trenches and handle large loads with ease. However, the machine’s reach may pose a challenge if used in confined spaces or narrow construction sites.
Overall Assessment
In conclusion, the JCB 2CX Extradig is a versatile machine suitable for various construction projects. Its features and specifications provide flexibility and increase productivity, but they also have some disadvantages. The machine’s advantages and disadvantages depend on the construction project’s requirements and
