Modern Quarrying Q2 2022

KEY TAKEAWAYS

Daily checks are easy as service points have been grouped to swiftly check fluid levels and to grease the machine every day.

The E300 LC is equipped with 6,8 litre six cylinder John Deere PowerTech Plus engine as opposed to the E210 which has a 4,5 litre engine.

The E300 LC combines power with smooth and low-effort control. The performance of the excavators is achieved through four power modes.

Remote diagnostics enable dealers and customers to monitor machines remotely and react quickly and proactively when problems occur.

These engines are fuel efficient even though, for me, fuel efficiency is subjective as it is influenced by the altitude of where the test took place.

PowerTech engine to deliver excellent power, control and efficiency. Performance and uptime Makgate explains that John Deere’s strategy for the design of its construction machines revolves around performance, uptime and cost of ownership. “The E300 LC has been built to deliver optimal uptime, has heavy-duty booms and arms, a robust electrical system while the hydraulic routing has been optimised,” Makgate says. The excavator employs reliable digging structures and hydrau lic, electrical and undercarriage components. “Consider, for instance, the hydraulic routing of our machines: in most cases when an excavator fails it will be with hydraulics. It takes long to trace where the problem is, whether it is an oil leak or a problem with the feedline,” says Makgate. “Our hydraulic lines have been simplified with less such lines, so if a cylinder breaks it is easy to replace it,” he explains. Aside from a simplified

The 30-ton E300 LC is a general construction machine that is ideal for applications including quarrying, contracting, mining and general construction.

applications,” he adds. The E300 LC is equipped with 6,8 litre six cylinder John Deere PowerTech Plus engine as opposed to the E210 which has a 4,5 litre engine. “These engines are fuel efficient even though, for me, fuel efficiency is subjective as it is influenced by the altitude of where the test took place. However, compared to excava tors currently in the market, it is about 6 ℓ per hour more fuel effi cient,” says Makgate. The machine is also equipped with auto-idle which reduces engine speed when hydraulics are not in use. The E300 LC’s open-centre hydraulic system is fully inte grated with the John Deere

applications including quarrying, contracting, mining and general construction,” he says. “The E300 LC falls in between a small contractor type of machine and semi-mining and fits into this segment because the bucket can be removed and fitted with different types of attachments,” says Makgate. The heavier nature of the machine makes it even more effective. “The E300 LC has a 2,9 m low reach. It is offered in a short and long carriage – the latter gives more stability on the machine as the undercarriage is slightly longer. It is a good machine for contractors moving between different construction
