The JS145 is a 14.5-tonne tracked excavator that’s been designed, tested and manufactured without compromise. At its heart is the new JCB EcoMAX engine – the last word in efficiency, performance and productivity.

Key Benefits

Brand new Stage 3B/Tier 4i EcoMAX engine
Hydraulic raised cab is 2.15m higher than standard
Long Reach option for even more efficient excavation
Up to 10% fuel saving over outgoing model
Large attachments and options range for versatility
Advanced hydraulic technology throughout

The JS145’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.

JCB JS145s boast the best components in the industry, including Berco running gear, Kawasaki pumps and Kayaba hand control valves.

Our EcoMAX Stage IV/T4F engine has been tested for 110,000 hours in 70 different machines across the toughest applications and environments to ensure durability.

The high-strength undercarriage uses a fully welded X frame construction for long-term durability even in the most demanding applications.

A closed box-section revolving frame increases strength, reduces stress, and is highly resistant to impact damage. The JS145’s high-strength rigid upper frame provides maximum durability and support.

There’s a wide range of attachments available (compatible with JCB’s quickhitch system) to make the JS145 even more versatile. This includes lifting, excavating, grading, unloading, multi and, of course, versatility attachments, enabling you to carry out a wide range of tasks.

A hydraulic raising cab option raises the cab 2.15m higher than standard for great visibility into high-sided containers. This makes it perfect for waste applications.

A Long Reach option extends the JS145’s working range for even more efficient, productive excavation, making it ideal for trench-digging.

For ultra versatility, JCB offers a full list of auxiliary pipework options including hammer, auxiliary and low flow.

With a massive 92 kN bucket tearout and fast cycle times, the JS145 is extremely productive in all applications, while JCB’s innovative hydraulic regeneration system means oil is recycled across the cylinders for faster cycle times and reduced fuel consumption.

Our EcoMAX Stage IV/T4F engine uses less fuel than our Stage IV/T4i units, saving you money. This is partly because EcoMAX produces high torque at just 1500-1600 rpm, and also because JCB uses efficient advanced hydraulic technology.

JCB JS145s have excellent front visibility, with a 70/30 front screen split and a clear view of the front right track for easy, safe trench digging and manoeuvring.

Because it doesn't require bulky after-treatment like a DPF, the new compact EcoMAX T4F engine can be housed under an innovative low-level bonnet, providing excellent rearward visibility.

For tremendous speed and control, a JCB JS145 has a balanced slew and electronic/hydraulic controlled slew braking. It can also be specified with proportional auxiliary control options for even more smoothness and precision.

An easy-to-read 3.5” colour multi-function display provides instant operational information, and has customisable home screens.

JCB JS145 cabs use 6 viscous rubber mounts to minimise noise and vibration. This creates a quieter working environment, inside and out, meaning you can use the machine at any location, at any time.

By using graphite impregnated bronze bushes on the JS145, we’ve increased boom and dipper greasing intervals to 1000 hours for normal applications. 

JCB’s In-Cab Monitor checks engine oil levels, coolant, and system errors on start-up. 

Unlike most Stage IV/T4F engines, JCB EcoMAX doesn't use a Diesel Particulate Filter (DPF), saving you additional AdBlue fluid level maintenance.

Our innovative recalibration option allows EcoMAX to run on lower grade fuels. This means the JS145 can be resold across different territories, which improves residuals.

The JS145 bonnet opens front-to-rear for easy and safe engine service access.

The cab can be specified with Rollover Protection Structure (ROPS) and Falling Objects Protection Structure (FOPS).

JCB JS145s have a large glass area and low bonnet line for superb visibility.

JCB’s 2GO system fully isolates hydraulic functions to avoid unintended movements.

There’s no need to climb onto the JS145 to check oil levels; all routine servicing can be done from ground level.

JCB’s Safety Level Lock fully isolates hydraulic functions to avoid unintended movements. Our New Start function means a JCB JS145 can only be started in a safe locked position via two separate inputs.
