The JCB JS145 track excavator is 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 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 track excavators don’t end there either.
