The JCB JS300 weighing in at 31 tonnes, it’s blessed with exceptional efficiency, strength, productivity, comfort, safety and ease of maintenance.
The JS300’s new DIESELMAX engine provides up to 25% fuel savings over outgoing models, while a closed box-section revolving frame increases strength and reduces stress. We’ve also created a new high-strength boom and dipper for this excavator, and we’ve used only the very best components, like Berco running gear, Kawasaki pumps and Kayaba main control valves.
Our 6-cylinder JCB DIESELMAX engine has a high power rating of 165 kW. Yet, because it produces its power and torque at low revs, it’s very efficient too, providing up to 25% fuel savings over previously sourced Japanese engines. Simultaneous tracking and excavating is smooth and fast with intuitive multifunction operation, and our variable power bands allow operators of these excavators to tailor performance to any application. 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 JS300 tracked excavator when its hydraulics aren’t in use.
We’ve designed JCB JS300 tracked excavators to be comfortable, ergonomic, and intuitive to operate. Function switches on this tracked excavator are easy to reach and include the heater and climate control panels. The JS300 tracked excavators have a spacious luggage tray behind the operator’s seat.
The JCB SMART Controller System keeps tabs on functions and inputs during different working modes.
Cushioned boom and dipper ends prevent shock loadings, protect your excavator, and increase operator comfort, while 6 viscous rubber mounts minimise noise and vibration. To keep everything under control, JCB JS300 tracked excavators have a balanced slew and electronic/hydraulic controlled slew braking. A large floor area with large high grip pedals gives safe, easy and precise tracking. A 70/30 front screen split provides a clear view of the front right track, while a large laminated glass roof window gives this excavator exceptional all-round visibility.
We use Finite Element Analysis with extensive rig and endurance testing to make these excavators last longer. A JCB JS300’s reinforced boom and dipper is made of high tensile strength steel, with single piece wrapper plates and internal baffle plates for long life durability. The high-strength undercarriage of JS300 tracked excavators 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 JS300 tracked excavators is welded to both the upper and lower undercarriage frames, and stiff, durable doors provide further strength.
For ultimate reliability, we construct our tracked excavators using only the very best componentry, including Berco running gear, Kawasaki pumps and Kayaba main control valves.
