The JCB JS145W wheeled excavator weighs in at around 14.5 tonnes. It’s engineered with exceptional strength, productivity, efficiency, comfort, safety and ease of maintenance.

A fully welded box section revolving frame increases strength and reduces stress. It also makes this excavator highly resistant to impact damage. We’ve used strong parts too – premium industry standards in fact.

Meanwhile, this excavator’s engine is a highly efficient EcoMAX 4.4 litre unit, compliant with Stage 3B/Tier 4i. That represents a 10% less fuel consumption over our out-going model and does not require a Diesel Particulate Filter. The benefits of JS145W wheeled excavators don’t end there either.


  • 82 kN bucket tearout
  • Stage 3B (T4i) compliant JCB EcoMAX engine
  • 10% improved fuel efficiency than outgoing model
  • Spacious, comfortable cab design with excellent visibility

We’ve designed the JCB JS145W wheeled excavator to be low maintenance and easily serviceable. Which makes it 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 this excavator. Grease points are centralised on a JS145W 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, JS145W wheeled excavators’ engine radiator, hydraulic cooler and intercooler can be serviced individually and cleaned easily.


Before you buy a wheeled excavator, you need to know it’s going to be tough enough to perform any job you ask of it. Fortunately, with a JCB JS145W, strength and durability come as standard.

We use Finite Element Analysis with extensive rig and endurance testing to make this excavator last longer. A JCB JS145W’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 JS145W 14.5 tonne wheeled excavators is of a fully enclosed, fully-welded box section for long-term durability even in the most demanding applications, and the rigid upper frame provides maximum durability and support.

The turret on a JS145W wheeled excavator is then welded to both the upper and lower undercarriage frames, and stiff, durable doors provide further strength.


We’ve designed the JCB JS145W wheeled excavator to be comfortable, safe, ergonomic, simple and intuitive to operate. Which is good for operators of this excavator but even better for you; after all, great ease of use equals great productivity. 

Cushioned boom and dipper ends prevent shock loadings, protect your machine and increase operator comfort, while 6 viscous rubber mounts minimise noise and vibration. 

A 70/30 front screen split for a clear view forwards, plus a large laminated glass roof window provide these wheeled excavators with exceptional all-round visibility 

To keep everything under control, a JCB JS145W wheeled excavator has a balanced slew and electronic/hydraulic controlled slew braking. Function switches are easy to reach and include the heater and climate control panels, while the side unit doubles as part of the immobiliser code selector.


It’s more important than ever to save money and time so it’s just as well that a JCB JS145W wheeled excavator is designed to make the most of both.

Our Stage 3B/Tier 4i compliant EcoMAX engine is extremely efficient too, because it produces very high torque at low revs.

An 82kN bucket tearout makes the JS145W excavator highly productive, and the special JS range quickhitch system makes attachment changing fast and easy.

Simultaneous moving and excavating is smooth and fast with an intuitive multifunction operation, and four operating work modes allow operators of JS145W wheeled excavators to tailor performance to any application. Auto, Economy, Precision and Lifting modes provide very different optimised settings.
