Company launches the biggest and most powerful X-Series crawler excavator to date 

JCB have expanded their popular X-Series range of tracked excavators with the unveiling of the biggest and most powerful model yet – the new 370X. The heavy-duty earthmover will bring its industry leading levels of productivity, durability, and reliability to the 35–40-tonne sector.

Paul Swallow, JCB business head - excavators, said: ‘With more power, increased strength and durability, reduced fuel consumption, and lower ownership costs, the JCB 370X is a major step forward for customers in the 35–40-tonne class. With fantastic operator comfort and control, the 370X delivers a heavy-duty excavator solution for markets around the world.’

The JCB 370X is powered by the latest Cummins L9 diesel engine, which is certified as EU Stage V and EPA Tier 4 Final compliant. This 8.9-litre, six-cylinder engine boasts a 14% power increase over the outgoing JS370, with 240kW (322hp) available at just 1,700 rev/min. The engine delivers this maximum power within a reduced operating rev range, to increase fuel economy and reduce overall noise levels. A Tier 2 common-rail engine is available for non-legislative territories.

 

The latest-generation Kawasaki tandem hydraulic pump operates with an increased 350 bar pressure, rising to 380 bar during power boost cycles. Combined with a latest-generation valve block and hydraulically operated cooling fan with reversing function, this contributes to class-leading efficiency. In tests, the 370X was capable of moving up to 4.5-tonnes more material per litre of fuel and up to 86 tonnes per hour more than competitors.

All major structures and components have been designed with additional performance and productivity in mind. A heavier counterweight contributes to added stability, whilst larger structures cope with the additional forces. Increased service pipework diameters and raised hydraulic pressures result in more power at the dig end, which has been redesigned with cast boom foot and hydraulic ram pivot points for additional strength and longevity.

The 370X is supplied with a 6.45m monoboom, with a choice of 2.63m, 3.23m, and 4.03m dippers. Optional heavy-duty dippers have additional crush bars and reinforcement to cope with arduous applications. Bucket pin diameter has been increased and the machine can be fitted with a new JCB dual-pin quick-hitch, to pick up 90mm or 100mm attachments. There are also new 2.1m3 XHD and 2.43m3 XHD buckets available, plus JCB will offer a new HM330T hydraulic breaker specifically for the 370X.

As with all X-Series machines, the 370X benefits from the JCB Command Plus ROPS cab. As well as being one of the largest excavator cabs on the market, with 2.86m3 of volume, the Command Plus cab benefits from a heated air-suspension seat and a reduced 69dB in-cab noise level.

The cab is further improved with a new 10in touchscreen monitor with a new user interface called JCB UX, whilst the switch panel incorporates more customizable hot keys, allowing further personalization for the operator. Climate control, a radio with DAB option, keyless start, and twin cameras for added visibility are all standard equipment.

The JCB UX interface has up to 25 user profiles, which can all be customized with the ability for operators to set the joystick configuration to meet their individual requirements. Mobile phone connectivity has been improved with phonebook integration via the monitor. The machine is exceptionally easy to use and help guides are available within the monitor, along with ‘how to’ videos, covering all of the features of the JCB UX system.

The 370X delivers real-time monitoring of all fluid levels on the in-cab display. The machine also benefits from extended service intervals, with hydraulic intervals doubled to 2,000 hours, engine coolant service now required at 3,000 hours, whilst the air filter element intervals have been extended up to 2,000 hours. The machine boasts three work modes to optimize digging, lifting, or economy. Auto-stop and Auto-Idle engine functions are also standard, to reduce fuel consumption during idling, further boosting total cost of ownership.

The 370X is available with a range of options, to tailor the machine to an individual customer’s requirements. These include auxiliary hydraulic circuits with up to 15 attachment settings and a premium heated and cooled operator’s seat. LED lights are now standard, with options available to increase to up to 14 LED work lights. The machine can also be offered with the JCB 2D and 3D-ready INTELLIGRADE system, providing machine control solutions to enhance productivity, accuracy, and safety. A bird’s-eye 360° camera system, integrated within the 10in display, can also be offered, along with high visibility, all-round handrails.

The 370X follows the styling and design first seen on smaller X-Series JCB excavators, with robust double-skinned steel service doors and tube-in-tube bolt-on handrails.
