JCB Turbo Sitemaster: Analysis of Features and Specifications

Introduction

The JCB Turbo Sitemaster is a 4WD, front-loading backhoe excavator known for its versatility, high performance, and reliability. This article analyzes its key features and specifications, highlighting the advantages and disadvantages of each.

SideShift or CenterMount

One of the distinguishing features of the JCB Turbo Sitemaster is its SideShift or CenterMount option for the backhoe. While SideShift allows for better maneuvering in tight spaces, CenterMount distributes the weight more evenly, improving stability. The advantage of SideShift is that it allows the operator to get closer to the work area and provides greater flexibility in confined spaces. However, CenterMount offers greater stability and is preferable when working on uneven terrain, although it may not be as efficient in tight spaces.

SAE Dig Depth

The JCB Turbo Sitemaster has a maximum SAE dig depth of 5400mm, making it suitable for a wide range of excavation tasks. This depth allows for efficient digging in deep trenches, foundations, and other applications where depth is critical. The advantage of this depth is that it enables the operator to reach deeper into the ground without having to move the machine, saving time and effort. However, the downside is that it may not be necessary for every job, and the additional depth can add to the cost of the machine.

Reach @ Ground Level

With a reach of 7840mm at ground level, the JCB Turbo Sitemaster is ideal for tasks that require extended reach, such as loading trucks or digging over obstacles. The advantage of this reach is that it improves versatility, allowing the operator to access work areas that might otherwise be difficult to reach. However, the disadvantage of such a long reach is that it may reduce stability, creating a higher likelihood of tipping if the machine is not operated properly.

Loading Height

The loading height of the JCB Turbo Sitemaster is 5050mm, making it suitable for loading materials into trucks or onto elevated surfaces. The height allows for efficient loading and unloading without requiring additional equipment. However, the disadvantage of this height is that it may not be necessary for all jobs, and it can add to the overall cost of the machine.

Bucket Width, Min-Max

The JCB Turbo Sitemaster has a bucket width that ranges from 300-900mm, providing versatility in digging and loading tasks. The advantage of this range is that it allows the operator to customize the bucket width based on the task at hand, improving efficiency and productivity. However, the disadvantage is that changing the bucket width may require additional time and effort, reducing overall efficiency.

Bucket Breakout

The bucket breakout of the JCB Turbo Sitemaster is 5600kgf, providing excellent digging and loading capabilities. The advantage of this breakout is that it allows the operator to easily dig through tough materials and load heavy materials without issue. However, the downside is that the breakout force may be unnecessary for some tasks, adding to the overall cost and weight of the machine.

Dipper Breakout

At 3017kgf, the dipper breakout of the JCB Turbo Sitemaster is less impressive than the bucket breakout but still reliable for many excavation tasks. The advantage of this force is that it allows the operator to carry out smaller tasks with precision and ease. However, the disadvantage is that it may not be appropriate for every task, and for larger excavations, a higher breakout force may be necessary.

Slew System

The JCB Turbo Sitemaster uses a Rack&Pinion slew system, which provides highly precise and smooth movement in both directions. The advantage of this system is that it enables the operator to quickly and accurately position the boom, improving overall productivity and efficiency. However, the disadvantage is that it may be susceptible to wear and tear over time, reducing its lifespan and requiring regular maintenance.

Loader Bucket Capacity

The JCB Turbo Sitemaster has a bucket capacity of 0.9m3, making it suitable for loading and unloading a wide variety of materials. The advantage of this capacity is that it provides the operator with a high degree of flexibility when it comes to loading and unloading different materials. However, the disadvantage is that the bucket capacity may not be appropriate for all tasks, and larger capacities may be required in certain applications.

Dump Height

The dump height of the JCB Turbo Sitemaster is 2650mm, providing ample height for efficient unloading of materials into elevated spaces. The advantage of this height is that it enables the operator to unload materials from the machine with ease, improving overall productivity. The disadvantage, however, is that a greater dump height can lead to instability, increasing the chances of tipping over.

Engine, Transmission, and Drive

The JCB Turbo Sitemaster is powered by a Perkins 1004.4T engine, delivering 67 kW of power at 2200 rpm. The engine has a displacement of 3.99 liters and four cylinders, providing reliable and consistent power. The transmission type is PS TC, allowing for smooth and efficient gear shifting. In addition, the JCB Turbo Sitemaster is equipped with four-wheel drive, enabling it to operate on rough terrain with ease. The advantage of this engine, transmission, and drive configuration is that they provide reliable operation with a high degree of control and stability. However, the disadvantage is that they may add to the overall cost of the machine and require regular maintenance to remain in optimal condition.

Speeds and Travel Length

The JCB Turbo Sitemaster has 44 forward speeds, enabling it to operate at various speeds depending on the task at hand. The maximum speed is 36 km/h, allowing it to move quickly between job sites. The travel length is 6000mm, enabling the machine to cover a greater distance in a shorter amount of time. The advantage of these features is that they enable the operator to move quickly and efficiently between job sites and complete tasks more quickly. However, the disadvantage is that they may be unnecessary for certain jobs and add to the overall cost and weight of the machine.

Width and Turning Radius

The width of the JCB Turbo Sitemaster is 2260mm, making it suitable for use on narrow job sites. The turning radius without brakes is 8900mm, enabling it to maneuver in tight spaces with ease. The advantage of these dimensions is that they allow the machine to access areas that might otherwise be difficult to reach. However, the disadvantage is that a smaller machine is not always as powerful as a larger one and may not be suitable for all tasks.

Overall Assessment

The JCB Turbo Sitemaster is a highly versatile backhoe excavator, suitable for a wide range of excavation tasks. Its key features and specifications offer a balance of advantages and disadvantages, depending on the task at hand. The machine’s SideShift or CenterMount option provides improved maneuverability and stability, while the SAE dig depth and reach at ground level allow for efficient digging and loading. The loader bucket capacity and dumping height are suitable for a wide range of materials, while the engine, transmission, and drive offer reliable power and control. Overall, the JCB Turbo Sitemaster is a reliable and cost-effective option for those seeking a versatile backhoe excavator
