My Industry:  Construction

The 4-wheel steer JCB 4CN is similar to the JCB 4CX but uprated with our innovative knuckleboom for added versatility. It’s one of the largest backhoe models we produce, recently uprated with a host of performance, comfort, safety and efficiency improvements.

Like our new award-winning EcoMAX T4i-compliant engine, which meets Tier 4i legislation without bulky DPF or SCR; compact installation provides uncompromised visibility and manoeuvrability. The 4CN also has high ground clearance and 4 equal-sized wheels, so it can tackle terrain unlike any other backhoe.

A DRIVETRAIN WITHOUT COMPROMISE

  • The 4CN’s new EcoMAX engine is designed, tested and built by JCB to work perfectly with JCB axles and gearboxes. T4i-compliant EcoMAX produces power and torque at around 1200 rpm for responsiveness and fuel-efficient matching of the transmission and hydraulics.
  • Because EcoMAX doesn’t use exhaust after-treatment, it doesn’t need costly heat-resistant lube oils or Adblue, saving servicing costs. And, because EcoMAX can be adapted to run on lower-grade fuels, Backhoes are resalable across different territories, which boost residuals.
  • JCB 4CN engines are tried and tested. We’ve built 200,000 DIESELMAX engines since 2004, and we’ve tested EcoMAX for 110,000 hours in 70 different machines across the toughest applications and environments.
  • For ultimate loading performance, productivity and roading efficiency, the JCB 4CN’s EcoMAX engine delivers as much as 81kW (109hp) and 516Nm of torque.
  • JCB’s unique TorqueLock system is standard-fit on all 81kW (109hp) powershift 4CN models. Combined with our optional 6-speed Autoshift transmission, it can help save up to 25% on fuel and 10% on road travel time.
  • An optional limited slip differential gives a JCB 4CN superior traction and performance, as well as reduced tyre wear.
  • The 4CN JCB backhoe loader is fitted with EcoRoad technology to provide the highest efficiency and productivity levels when roading. Fuel consumption is reduced, while machine speed and working area are increased by up to 10%.
  • The JCB 4CN has 3 modes of 4-wheel steering and a large 1.3m3 shovel is available for exceptional on-site productivity.
  • Our 6-speed autoshift transmission with floor mounted kickdown switch provides great pulling power on the 4CN.

EXCELLENCE IN EXCAVATION

  • The JCB 4CN has our innovative knuckleboom: a 30˚ articulation angle between boom and dipper gives a huge 240˚ working envelope, allowing it to excavate around immovable objects like trees and telegraph poles.
  • A new high output variable flow pump reduces the JCB 4CN’s cycle times, saves fuel and, on manual backhoes, lighter lever effort makes control easier.
  • There’s more tractive effort at the 4CN’s pile than ever, thanks to new variable flow pump power management and the new JCB EcoMAX engine.
  • The 4CN’s 4-ram self-levelling loader automatically adjusts the shovel on both the raise and lower cycle without any need for manual adjustment. It also provides unhindered front shovel visibility, especially when loading at height.
  • The optional combined hammer and bi-directional circuit provides optimised low-flow and high-flow hydraulic power with low back pressure for great attachment versatility.
  • At the Loading ends of the JCB 4CN, our return to dig feature automatically resets the shovel into the loading position, and selectable transmission disconnect diverts maximum hydraulic power from the engine to the loader arms.

STRENGTH: WHY COMPROMISE?

  • JCB 4CN axles and transmission are designed to withstand a 12,000-hour design life; heavyweight axles are built to withstand serious shock loads. The rear axle alone has a static load rating of 25,000 kg, and a dynamic load rating of 12,500 kg.
  • We use stress-relieved fabrication for the 4CN’s boom – by heating materials to over 650˚C for over 16 hours, we make sure the metal is evenly heated, doubling boom life.
  • The 4CN’s pre-production testing regime included 100,000 loading cycles, 500,000 excavating cycles, 360,000 gearchange cycles, extensive bump track testing to ensure structural integrity, and thousands of hours of endurance testing.
  • We also carried out extensive EMC (Electromagnetic Compatibility) testing on the 4CN; this ensures that signals from mobile phones and radios don’t affect the machine in any way.
  • Every new JCB 4CN is put through around 600 performance checks on the production line.
  • Our construction materials are tested to the limit by exposing them to extreme temperatures, chemicals, salt, oil and light. That way, we know they’ll survive the most hostile conditions.
  • For rigidity and hose protection, there are flat plate D-pressing loader arms on the JCB 4CN.
  • The robot welded single-piece chassis on the 4CN maximises strength and minimises weight.
  • Hydraulic hoses are approved to work down to -40°C and all JCB 4CN materials are tested to extreme temperatures and exposed to chemical, salt, oil and sunlight to ensure maximum protection.

A QUALITY WORKPLACE

  • The JCB 4CN is designed to enable fatigue-free, productive day-long working. The cab is rubber-mounted and isolated for low noise and vibration.
  • A JCB 4CN cab is inspired by the automotive industry for familiarity. A heated air suspension seat, heated front screen, and a hot beverage machine are just some of the quality features you can find within.
  • Ergonomic seat-mounted excavator-style controls – with optional excavator-style backhoe and loader servo controls – provide fingertip control, great comfort and excellent manoeuvrability.
  • For more comfort and less material spillage, the 4CN’s Smoothride System (SRS) minimises bounce during travel. You can quickly reset your shovel to the digging position with our return-to-dig feature too.
  • High back-off brakes reduce viscous drag during roading and rehandling, which improves economy by up to 1%.
  • The optional handheld tool circuit means you can increase versatility by using your 4CN as a power source for handheld tools, such as drills, breakers, cutters and even water pumps.
  • JCB 4CN backhoe loaders are quiet places to work, both inside and out – particularly the 55kW (74hp) models, which are the quietest in the industry.
  • Controls on the 4CN feature an LCD panel detailing machine hours, service information fuel level and system warnings. A 360° view through tinted windows aids comfort, productivity and safety.
  • Our innovative scoop design one-piece rear windscreen allows JCB 4CN operators to see right into the trench when excavating.
  • To make operators feel right at home in the 4CN, they can opt for the standard-fit traditional manual control system, with a choice of three control patterns – JCB X, SAE+ and ISO+. There’s even an in-cab coolbox.

LESS SERVICING, MORE SERVICE

  • An upgraded engine and fuel filter prevents engine wear and extends our EcoMAX engine’s working life.
  • Daily under bonnet checks are a thing of the past with the JCB 4CN – all engine checks are done automatically by the CANBUS electronics engine management system.
  • Most Tier 4i engines use a Diesel Particulate Filter (DPF) or SCR, requiring additional AdBlue fluid level maintenance – EcoMAX doesn’t.
  • For an even more efficient backhoe experience, JCB’s new multi-functional instrument control panel can provide the 4CN’s current and average fuel consumption, as well as service faults and critical faults.
  • The plastic fuel tank on a JCB 4CN is completely rustproof to prevent rust forming in the tank, which protects the fuel injection system. The single-piece composite cab floor is also rustproof, with moulded water channels.
  • LiveLink telematics can provide accurate up-to-date machine health information on your 4CN. The system can also maximise uptime by making it easy to service your machines at the most efficient times possible.
  • The 4CN’s power brakes utilise the existing hydraulic supply, reducing operator costs and daily service checks.
  • A large fuel tank means extended periods between fill ups for a longer, more productive working day.

THE SAFE CHOICE

  • Getting into a JCB 4CN is easy and safe – there are large grab handles, a wide door opening, and open grid design steps that prevent dirt build-up.
  • Our new unique integral shovel street pads option prevents ground damage from your 4CN and, therefore, costly repairs.
  • Power brakes allow efficient, safe stopping power with low pedal effort.
  • You can keep a close eye on your 4CN with JCB’s LiveLink telematics system; this protects your business from unauthorised usage and vehicle thefts.
  • JCB tractor backhoes have always had class-leading braking performance but the 4CN takes this even further. Modelled on car brakes, our power brakes provide proportional braking throughout the pedal travel for superb control.
  • There’s a redesigned and lowered ergonomic brake pedal on the 4CN, while full floating discs reduce drag, improve fuel economy and increase road speed.
