JCB introduces two new 3.5-tonne excavators

JCB introduces two new 3.5-tonne excavators, a zero-tailswing compact model and a conventional machine, expanding its ‘Next Generation’ lineup to meet customer demand.
Both machines are powered by a three-cylinder Tier 4 Final Perkins engine, delivering 24.6 hp. This engine uses mechanical fuel injection and has no requirement for a diesel particulate filter (DPF) or any form of exhaust aftertreatment.
A programable auto-idle function (2-30 secs) reduces engine speed to 1,400 rpm when the levers have not been used for a pre-set time. When the left-hand control pod is lifted, isolating the machine’s hydraulics, the engine speed falls again, to 1,100 rpm, reducing fuel consumption and noise levels.
The dozer blade design has been improved, with a revised curvature for improved roll performance. Pivot pins feature pin-end greasing, making it easier to service and all plated surfaces are angled to minimize spoil retention. Dozer ram hoses now pass through bulkhead connectors, mounted on the outside of the undercarriage, making it easier to replace them in the event of accidental damage. Optional dozer float and a four-way dozer are now offered.
Dig-end geometry has been revised to improve lifting and loading performance. A single 96.5-inch main boom is used on both machines and there are two dipper arm options available.
The machines are provided with an immobilizer to prevent theft and JCB LiveLink is standard, providing a telematic link to the excavator to ensure that it remains well-maintained and delivering maximum productivity.
