The JCB JS240 is the 24-tonne model in our heavy tracked excavators range. It’s blessed with exceptional strength, productivity, efficiency, comfort, safety and ease of maintenance.

A closed box-section revolving frame increases strength and reduces stress. It also makes these 360 excavators highly resistant to impact damage. We’ve used only the very best parts too, like Berco running gear, Kawasaki pumps and Kayaba main control valves.

  • Up to 39% better dipper tearout than competitors
  • Up to 15% better bucket tearout than competitors
  • 147 kW Tier 3-compliant Isuzu engine
  • Class leading maintenance access
  • Robust, durable upper structure and doors
  • Spacious, comfortable cab design with excellent visibility


We’ve designed JCB JS240 tracked excavators to be comfortable, ergonomic, simple and intuitive to operate. Which is good for operators of 360 excavators but even better for you; after all, great ease of use equals great productivity.

Function switches on this tracked excavator are easy to reach and include the heater and climate control panels, while the side unit doubles as part of the immobiliser code selector.

JCB JS240 tracked excavators have a spacious luggage tray behind the operator’s seat.

The JCB Advanced Monitoring System keeps tabs on functions and inputs during different working modes.

Demist/defrost keeps a JS240 360 excavator’s front window clear at all times in any conditions.


Our Tier 3 compliant Isuzu 6HK engine has a high power rating – 147 kW – but it produces all of its torque at low revs for optimum efficiency.

A massive 192kN bucket tearout makes our JS240 tracked excavator up to 15% more productive than its closest competitors. Better still, a dipper tearout of 179kN is up to 39% greater than rivals.

The special JS range quickhitch system makes attachment changing fast and easy on this 360 excavator.

Simultaneous tracking and excavating is smooth and fast with intuitive multifunction operation, and four operating work modes allow operators of these 360 excavators to tailor performance to any application. Auto, Economy, Precision and Lifting modes provide very different optimised settings.

JCB’s tracked excavators use hydraulic regeneration to recycle oil across the cylinders for faster cycle times and reduced fuel consumption.

Auto-idle technology automatically reduces the engine speed of the JS240 tracked excavator when its hydraulics aren’t in use.


We’ve designed JCB JS240 tracked excavators to be low maintenance and easily serviceable. Which makes them affordable, efficient and highly productive.

Bonnets open and close easily with gas-assisted cylinders, and the service bays are large and wide for good access. 1000-hour boom and dipper greasing intervals and a 5000-hour oil life provide maximum uptime on these 360 excavators. Grease points are centralised on a JS240 24 tonne excavator too, for safe and easy access to high level pivots. Likewise filters (engine oil, hydraulic oil and fuel).

Because they’re mounted side by side, the JS240 tracked excavator’s engine radiator, hydraulic cooler and intercooler can be serviced individually and cleaned easily.


Before you buy tracked excavators, you need to know they’re going to be tough enough to perform any job you ask of them. Fortunately, with a JCB JS240, strength and durability come as standard.

We use Finite Element Analysis with extensive rig and endurance testing to make these 360 excavators last longer. A JCB JS240’s reinforced boom and dipper is made of high tensile strength steel, with single piecewrapper plates and internal baffle plates for long life durability.

The high-strength undercarriage of a JS240 24tonne excavator is of a fully-welded X-frame construction for long-term durability even in the most demanding applications, and the rigid upper frame provides maximum durability and support.

The turret on JS240 tracked excavators is then welded to both the upper and lower undercarriage frames, and stiff, durable doors provide further strength.
