JS145 Tracked Excavator 

Engineered 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 strong parts too – premium industry standards in fact.

Meanwhile, this excavator is powered by the highly efficient EcoMAX Tier 4 Final compliant engine, offering superb productivity and reliability.The benefits of the JS145 series of tracked excavators don’t end there either.


Before you buy a tracked excavator, you need to know they’re going to be tough enough to perform any job you ask of it. Fortunately, with a JCB JS145, 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 JS145’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 JS145 14.5 ton 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 JS145 tracked excavators is then welded to both the upper and lower undercarriage frames, and stiff, durable doors provide further strength.


It’s more important than ever to save money and time so it’s just as well that JCB JS145 tracked excavators are designed to make the most of both.

Our Tier 4 Final compliant EcoMAX motor is extremely efficient too, because it produces very high torque at low revs.

A 92kN bucket tearout makes our JS145  excavators highly productive, and the JCB JS range quickhitch system makes attachment changing fast and easy.

Simultaneous tracking and excavating is smooth and fast with an intuitive multifunction operation, and four operating work modes allow a JS145 14.5 ton excavator operator to tailor performance to any application. Auto, Economy, Precision and Lifting modes provide very different optimized settings.

Maximum productivity, minimum spend
  • 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 engine speed when hydraulics aren’t in use.


We’ve designed the JCB JS145 tracked excavator to be comfortable, safe, 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.

Safety and comfort features include:
  • Cushioned boom and dipperends
  • 70/30 front split screen
  • Balanced slew and electronic/hydraulic controlled slew braking
  • JCB JS145s have spacious storage behind the operator’s seat.
  • A new SMART controller keeps tabs on functions and inputs during different working modes.
  • A large floor area with large high grip pedals gives easy and precise tracking.
  • Demist/defrost keeps a JS145 front window clear.
