It's Clean

G40RS Generators are the perfect solution for your energy needs as they come standard with Stage V emissions-compliant engines and have dramatically reduced particulate and Nox emissions compared to Stage I engines. Not only that, G40RS Generators also contain modern fuel efficient engine which enable you to save money with minimal fuel consumption and comply with onsite emissions restrictions. G40RS Generators are a smart choice for those looking to reduce their greenhouse gas emissions and leave a smaller carbon footprint.

It's Tough

Get the G40RS Generator for unbeatable protection! Constructed with heavy duty corrosion-resistant steel canopy, durable bunded base with 110% overfill capacity and heavy gauge steel that is twice as thick as the market standard, this generator ensures superior protection during both onsite use and transit. Plus, its oversized base frame complete with anchor points provide further safeguards while its oversized fork pockets, large rubber buffers and heavy-duty chain pull bar make it suitable for multiple environments – including harsh or saline – while extensive testing ensures maximum water ingress protection.

It's Quiet

Our JCB G40RS Generators are engineered to ensure a quiet operation. The G40RS generator is designed with a silent or super-silent version that optimises the fan design to deliver cooling at all loads. Additionally, G40RS generators feature an extensive vibration analysis process, meaning that only minimal engine noise is produced when in use. This allows the G40RS generator to operate around-the-clock or in noise sensitive areas without causing disruption. A quieter system also results in improved communication between staff, making these G40RS generators well-suited for many industrial and commercial applications.

It's Smart

The G40RS Generator has been specially designed to improve customer fleets. With engines and alternators set up in harmony, your fleet will run at an ultimate efficiency with excellent load acceptance. Paired with a large 24-hour fuel tank or optional 48-hour tanks, customers have the ability to reduce filling intervals and maximise productivity with the G40RS. JCB Livelink Telematics as standard allow for remote fleet management, further increasing efficiency and optimised servicing. The G40RS also features an automatic DEF top-up system to enhance performance even further, ensuring maximum productivity and extended run times while preventing premature failures of other components and prolonging the life of the machine. All of these features together make G40RS Generators an attractive choice when looking to remain in control of your fleet.
