Why choose the JCB 520X?

The 520X is a machine built on decades of JCB engineering experience. Designed for high load and high output environments, it delivers productivity, reliability and efficiency without compromise.

With 95% of parts available within 24 hours worldwide, and a lower total cost of ownership, the 520X is more than our biggest excavator: it’s your biggest advantage.

From extreme climates to the most unforgiving terrains, demanding projects need a JCB big excavator. The 520X is purpose-built to perform, and delivers:

  • Ultra-powerful X12 engine: our biggest excavator contains a huge 298 kW of power engine. For unstoppable productivity, even in extreme applications.
  • Powerboost function: perfect for tough ground conditions, the JCB excavator power boost button increases system pressure for up to 9 seconds for a 6% increase in tearout force.
  • Ultimate productivity: a dedicated, 6.5m boom, mass excavation specification and dual slew motor system delivers class-leading cycle times.
  • Ultimate versatility: with options including a 6.9m monoboom, double and triple grousertrack plates, and a range of hydraulic systems to suit various attachments.

Running a 50T excavator isn’t easy to do efficiently. But JCB has an unbeatable history of delivering low TCO for high-powered machines – and the biggest JCB excavator in the world is no exception. Minimum refuelling and service breaks. Maximum productivity:

  • Efficient operation: with eco, power & lift modes to suit different applications – operators can tailor their machine to their preferences.
  • Efficient serviceability: long service intervals, grouped greasing, quick drain points and a refuelling pump all help to maximise uptime.
  • Efficient features: including Engine Autostop, Auto Idle, and Automatic engine shutdown on selectable timer, to reduce fuel consumption and emissions.
  • Efficient cooling: by keeping the fan separate from the engine drive motor, there’s a more efficient use of space – and the option to add a larger fan. These are hydraulically-operated and reversible as standard.
  • Efficiency monitoring: with the unique JCB LiveLink system, you can keep a close eye on your machine’s location, fuel usage, CO2 emissions and maintenance – wherever you are in the world.

The JCB 520X is engineered with durability in mind, from the tracks and undercarriage to the doors, dipper and dig end. Every part of the machine is robustly constructed, ensuring longevity in the world’s most demanding applications:

  • Ultra-reinforced: our 50 tonne excavator undercarriage has the thickest structures in the X Series, twin-support top rollers and reinforced idler boxes range for supreme durability.
  • Tested to extremes: our dig-end has been proven to endure over 25,000 hours of destructive testing, with casted boom foot and nose end, as well as significant internal strengthening for ultimate durability.
  • Proven hydraulic components: crafted in Japan by industry experts to maximise the efficiency and lifespan of your machine.
  • Heavy-duty parts: with dipper lengths from 2.55m to 3.9m and larger bucket sizes available, our biggest mining excavator is more than a match for tough jobs.

The 520X is built with simplicity at its core. With JCB’s biggest excavator, you can start operating in just two seconds. With a simple, keyless start / stop button, in-cab ‘how to’ videos and our famous ultra-intuitive controls, it couldn’t be easier to get going.

  • Easy servicing: grouped filters and wide-open service bays makes maintaining this machine easier than ever.
  • Easy operation: with the intuitive X Series 10” colour touchscreen monitor and ergonomic switch gear. All supported by the built-in operator how to guides.
  • Easy visibility: with high-definition front and rear-view cameras as standard, and 360-degree camera options.

A comfortable operator is a safer operator – whether you’re in a mini digger or our biggest mining excavator. That’s why at JCB, your comfort is our priority:

  • Ultimate climate control: wherever you are in the world, you can work in comfort with HVAC, blinds, and suspension seats as standard.
  • Extra-large cab: the biggest JCB excavator also boasts our largest cab, with an ergonomic design and extra legroom.
  • Reduced operator fatigue: with double-cushioned viscous mounts that reduce vibration and cab noise to just 72dB.
  • Built-in connectivity: with Bluetooth audio and the JCB UX connection manager feature, operators can seamlessly sync their phone with their machine.
