It is aimed at markets with extreme environments and high productivity.
JCB is aiming at markets in Africa, the Middle East, Russia and countries in South East Asia. It is powered by JCB’s Dieselmax 672 six-cylinder engine. This 7.2-litre motor uses a mechanical in-line fuel pump, with a fixed geometry turbocharger and fixed cooling fan, to provide 165kW (221hp) of power. To ensure good performance in harsh operating conditions, the JS305 is equipped with air filters with a scavenge pre-cleaner as standard. This two-stage filter uses elements that are three times more efficient than a traditional pleated air element. The dust holding capacity of the filter is increased by 175% over a standard filter, eliminating the need for an after-market pre-cleaner. Engine oil and filter changes are set at 500 hours, while hydraulic and outer air filter service intervals occur at 1,000 hours. The air filter’s internal element can be changed at 2,000 hour intervals, with hydraulic oil changes set at 5,000 hours, for minimal downtime and reduced operating costs for the customer. The JS305 is equipped with six working lights as standard, to support machine operation around the clock. These light units are all protected by guards, to reduce the risk of damage and maintain safer working conditions.
The JS305 uses the same cab structure as the JS205, incorporating a simple to navigate display monitor. This colour monitor can be set to display a range of operating data and there is also no requirement for engineers to use a laptop to diagnose faults in the field on the machine. The display shows engine speed, the selected power mode, machine hours and breaker hours, time to service, any critical alerts, low/high travel selection and auto idle function selection. The monitor also records historical events for later service access, while it can also be used to diagnose engine and hydraulic temperatures, fuel level and battery voltage. The cab has air conditioning as standard and has auto temperature control, a full selection of mirrors to boost site safety and a mechanically adjustable suspension seat to keep them alert and productive.
The JS305 is equipped with a heavy-duty monoboom and a choice of 2.5m and 3.1m long dipper arms. Both dippers are supplied with a heavy-duty wear plate on the underside to provide protection from rocks. The machine’s upper structure sits on a standard long undercarriage with nine lower rollers and two upper rollers on each track frame. The idler area has been strengthened to withstand the toughest of applications and the undercarriage uses a fully welded X-frame construction. Track pads are available in 600, 700, 800 and 900mm widths, with both 12mm and 15mm grouser depths. Source: https://www.jcb.com/en-gb/about/news/2016/10/wraps-come-off-robust-new-30-tonne-excavator
