JCB 145

The 32,000-lb. JS145 crawler excavator is powered by a 108-hp Ecomax 4.4L diesel engine that meets Tier 4 Interim without using a diesel particulate filter or an exhaust after-treatment system such as selective catalytic reduction.

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. Meanwhile, this excavator is powered by the highly efficient EcoMAX Tier 4 Final compliant engine, offering superb productivity and reliability.


With any 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.

JCB used Finite Element Analysis with extensive rig and endurance testing to make that the 360 excavators last longer. A JCB 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.

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.

Productivity and efficiency

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.

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

A 92kN bucket tearout makes the 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.
