The JCB JS290 is a heavy tracked excavator and weighs approximately 29 tonnes. The equipment has excellent strength, efficiency and productivity and offers both safety and comfort. A closed box section revolving frame in the JCB JS290 reduces stress and boosts strength. The frame also makes the tracked excavator to resist impact damage.
The engine integrated in the excavator is Isuzu 161 kW 6HK unit, which is highly efficient and complies with Stage 3b and Tier 4i standards. All 360 excavators have been subjected to Finite Element Analysis with comprehensive rig and endurance testing to ensure their durability. A reinforced boom and dipper in the JCB JS290 excavator has been constructed from high tensile strength steel with internal baffle plates and single piecewrapper plates for improved durability.
The JS290’s undercarriage is made of a fully-welded X-frame construction to ensure extended durability even in extremely challenging applications, and the rigid upper frame offers high support and durability. In addition, the turret on JS290 is fused to the upper as well as lower undercarriage frames, while strong, long-lasting doors deliver extra strength.
The Tier 3-compliant Isuzu engine has a power rating of 161 kW, which is 25% more when compared to the outgoing model. The engine is also highly efficient since it generates 27% more torque at low revs, in contrast to the outgoing model.
The JS290 features a large 155kn bucket tearout, which makes the excavator 12% more productive. The unique JS range quickhitch system ensures that attachment changing is quick and easy. With an intuitive multifunction operation, concurrent tracking and excavating is made fast and easy. Operators can choose from four operating work modes, such as Economy, Precision, Auto and Lifting modes, to customize performance to suit any application.
Hydraulic regeneration is utilized by JCB’s tracked excavators to recycle oil across the cylinders for reduced fuel consumption and rapid cycle times. Auto-idle technology automatically brings down engine speed when hydraulics is not in use. The JCB JS290 tracked excavator is safe, simple, ergonomic and easy to operate, and thus provides better productivity. Moreover, cushioned boom and dipper ends boost operator comfort, protect the machine and prevent shock loadings, while six viscous rubber mounts reduce vibration and noise. A large laminated glass roof window promotes excellent visibility and a 70/30 front screen split provides a clear, visible view of the front right track.
The JCB JS290 tracked excavator has a balanced slew as well as an electronic/hydraulic controlled slew braking to keep everything under control. Operators can easily access function switches; heater and climate control panels are also included, while the side unit serves as part of the immobiliser code selector. The excavator has a huge luggage tray behind the operator’s seat; a spacious floor area with huge high grip pedals provides accurate and easy tracking; a sophisticated monitoring system checks inputs and functions during various working modes; and the demist/defrost feature keeps the front window clear.
The JCB JS290 tracked excavators can be serviced easily, making them efficient, affordable and highly productive. With gas-assisted cylinders, bonnets can be easily opened and closed. The service bays are wide to provide easy access. Dipper greasing intervals, 1000-hour boom and a 5000-hour oil life offer optimum uptime on these tracked excavators. Additionally, the excavators have grease points that are centralized to enable safe and convenient access to high level pivots. Similarly, filters such as fuel, hydraulic oil and engine oil are also centralized. Intercooler, hydraulic cooler and engine radiator in the JS290 tracked excavator can be serviced separately and cleaned easily since they are mounted side by side.
