JCB 4CX Sitemaster*, 2005 Technical Specifications

Introduction

The JCB 4CX Sitemaster is one of the most popular backhoe loaders on the market, known for its versatile performance and durability. Its technical specifications play a significant role in determining its performance and efficiency in a variety of applications.

Advantages

Sideshift and CenterMount

One of the advantages of the JCB 4CX Sitemaster is its SideShift or CenterMount. This feature provides flexibility in maneuvering the loader in tight or congested areas. It allows the operator to shift the backhoe sideways or mount it centrally to increase stability and work precision, reducing the chances of equipment damage.

For example, a contractor may have to work on an urban construction site with limited space. The ability to shift the loader sideways can help in accessing tight spaces like underground parking lots, narrow alleys, or cramped basements. Alternatively, when working on a highway construction project, the center mount increases stability when digging in rocky terrain.

Dig Depth and Reach

The JCB 4CX Sitemaster’s deep digging depth and reach capability also give it an advantage over other machines in its class. The loader’s SAE dig depth of 5530mm and the reach at ground level of 6540mm make it easier to dig deeper and reach further, reducing the need for time-consuming excavation work.

For example, in a pipeline construction project, the machine’s deep digging depth can come in handy when digging trenches in rocky or hard soil, while the long reach can be useful in scooping debris from deep holes, reducing the amount of manual labor required.

Loader Capacity

The JCB 4CX Sitemaster’s loader bucket capacity of 1.2m3 makes it one of the most efficient backhoe loaders in the market. It can carry higher loads in a single trip, increasing the work speed. This feature comes in handy in construction projects that require high volume load and unload operations.

For instance, in agricultural applications such as hay-bailing or silage harvesting, the loader’s increased hauling capacity reduces the number of trips needed to collect bales or move materials around the farm, reducing the overall time and energy spent on the job.

Engine Power and Transmission

The JCB 4CX Sitemaster’s engine power has a significant impact on its performance. With a horsepower of 74.6@2200rpm, it can handle heavy-duty workloads with ease. Its high torque is suitable for digging through tough soil and undertaking other demanding applications.

Moreover, the machine’s Full PS transmission system allows smooth shifting between forward and reverse, making it ideal for maneuvering around the worksite. Its two-wheel-drive and full four-wheel-drive provides an edge in various worksite scenarios, allowing it to traverse complicated terrains.

For example, in mining applications, the high engine power and advanced transmission system can come in handy when accessing mines in high-altitude areas and hauling ore to the surface.

Disadvantages

Operating Weight

The JCB 4CX Sitemaster’s operating weight of 8660kg limits the machine’s mobility on soft or unstable grounds. The heavy frame can sink or tear up landscapes with fragile topsoils or those with underground pipes and utilities that require sensitive handling.

For instance, construction projects in urban areas may require minimal impact on the surrounding environment. In such cases, alternative equipment such as mini-excavators may be more suitable for the job.

Bucket Width and Breakout

While the machine’s large bucket width of 2350mm makes it ideal for high-volume loading and unloading operations, it may also hinder its maneuverability in confined spaces. The bucket’s breakout force of up to 6130kgf may also be overkill for small-scale operations, leading to equipment degradation from excessive wear and tear.

For example, when working on a residential construction site, the large bucket size may damage adjacent properties or gardens. Instead, a mini excavator with a smaller bucket size and delicate breakout force may be more appropriate for the job.

Speed and Ride Control

The JCB 4CX Sitemaster’s maximum speed of 40.6 km/h may be suitable for open fields and highways but may not be ideal for congested or urban areas. Additionally, the optional ride control system may not be necessary on most worksites, increasing the machine’s overall cost.

For instance, urban projects with heavy pedestrian traffic may require slow-moving equipment or equipment that can handle traffic redirection before proceeding. A compact track loader or mini excavator may be more suitable in such a scenario.

Overall Assessment

The JCB 4CX Sitemaster is a versatile and durable backhoe loader suitable for various construction, mining, agricultural, and infrastructure projects. Its technical specifications provide notable advantages in maneuverability, digging depth, reach, loader capacity, engine power, and transmission. However, it has some limitations such as operating weight, bucket width and breakout, speed, and ride control. Operators and project managers should weigh the advantages and disadvantages of the machine’s technical specifications before making purchasing decisions.
