51R-1

Summary

The 5-tonne JCB 51R-1 mini digger is a reduced tailswing configuration machine, offering a winning combination of manoeuvrability, agility and lift performance.


Tracked excavators have been a part of the JCB manufacturing family for over 50 years. Using all of this experience and insight, our latest mini diggers like the new 51R-1 have been developed to exceed even your most exacting demands. Put simply, this is one of the strongest and highest performing mini excavators we’ve ever built.

It’s highly productive, compact, agile, innovative and economical to own. Not only that but it’s very safe to operate and easy to service too.

With a finite element analysis-designed heavy-duty structure as well as simplified H-frame construction, the undercarriage of this mini digger is both durable and confidence inspiring.

Our clean four-plate dipper design provides added structural strength and durability. The fully robot welded boom and dipper are made of high tensile strength steel, with internal baffle plates in the boom for long-life durability.

The optional heavy-duty kingpost features durable re-bushable pivots to optimise service life. It also provides a safe route for all excavator hoses.

The heavy duty boom cylinder guard and optional dipper and crowd ram guards give maximum excavator arm protection, even during the toughest jobs.

We only use trusted premium manufacturers including Perkins engines, Nachi and Bosch-Rexroth hydraulic components and Bridgestone tracks.

The hydraulic system boasts the latest industry technology “O-Ring Face Seal” (ORFS) hydraulic fittings, providing excellent sealing capabilities.

The new JCB 51R-1 mini digger has an even more spacious cab than before, with storage galore, a phone tray, stowage net and a cup holder. The whole area is accessed easily and safely via a large door.

Our new deluxe fully adjustable suspension seating provides great comfort for excavator operators; our heated air suspension option, meanwhile, has independent adjustable positions for the ultimate in ergonomics.

There’s a radio, 12V phone charger and powerful heater with window de-mister. A high performing air conditioning system* with 8 vents completes the picture.

JCB mini excavators boast an innovative new rotary controller and easy touch switches have been specially designed for easy operation. With ergonomic electro-hydraulic dozer control as standard, operators can achieve smooth and precise grading control.

You can alternate quickly between single and double-acting auxiliary flow thanks to a convenient switch in the cab.

For increased safety, there is a Thatcham approved immobiliser**, eliminating the possibility of an unauthorised start. Having the software system Livelink and Datatag** on the minis, will allow you to set a geofence and machine working restrictions.

A key benefit of the Livelink and immobiliser combination is the remote pin code management system, which allows you to remotely authorise or deny the usage of the machine. Up to 14 individual pin codes can be programmed into the system, offering the option to customise operator preferences by embedding a separate auxiliary mode in each code.

You can easily adjust and programme flow settings for specific attachments, with a built in memory to store your settings so that they can be easily retrieved between jobs. Information such as service and machine diagnostics help the operator to keep on top of the status of the machine. Alerts and service interval countdowns will keep you up to date, and always one step ahead of the possibility of downtime.

Live readings of fuel consumption give the operator an idea as to how the machine is performing at any stage of application.

*Air conditioning optional.

** Region specific


The reduced tailswing JCB 51R-1 mini digger is very manoeuvrable even in the most confined spaces because the overhang outside the footprint of the tracks is much less than you’d find on a conventional tailswing model.

In Europe, you have two engine options when you buy a JCB mini. Firstly there’s an efficient 2.2-litre Perkins 404D-22 engine delivering 35.7kW at 2000rpm. You can also opt for a Tier 4 Final/Stage 3B engine.

Tracking performance is smooth and precise, ensuring high dozer capabilities and fast travel times. To increase productivity, our auto kickdown motors automatically adapt to changes in terrain, increasing productivity and reducing operator fatigue.

Your JCB 51R-1 excavator generates huge dipper tearout forces of up to 29kN. What’s more, by perfectly matching our boom and dipper, we’ve created optimal dig end geometry, helping you to work and load in confined areas with ease.

Bucket rotation is a huge 181˚, offering great spoil retention during truck loading. Choose a dipper length to suit your application – from 1.45-1.82m – providing total versatility.

Smooth, precise and balanced multi-functioning is easy with this excavator, courtesy of a premium closed centre hydraulic system that provides improved flow sharing.

Because damage sometimes happens on sites, we use flat glass windows throughout the new JCB 51R-1 mini digger, as well as 100% steel bodywork, minimising possible replacement costs.

With our class-leading greasing intervals of 500 hours, you can expect minimal downtime. Better still, our new monitor provides alerts on your excavator’s diagnostic status.

Engine revs reduce when the operator’s armrest is raised, improving fuel economy and noise levels. There’s a One-Touch Idle feature that conserves fuel too. Programmable auto idle, meanwhile, can be activated when the controls have been inactive for a period.

Control your 51R-1 mini’s engine speed for different hydraulic flows by simply cycling through four different power bands: Light, Eco, Heavy and Heavy Plus. This means you can tailor performance to any application.

The patented low-pressure return line circuit further improves fuel efficiency because the pump doesn’t need to overcome a very high pressure before work can start.

Load-sensing hydraulics are standard-fit on this mini digger. This innovative feature means that your hydraulics only consume power on demand, conserving fuel for when you need it most.

The new JCB 51R-1 mini excavator cab is fully ROPS and TOPS compliant. For even more protection to both cab and operator, opt for impact protection glass on your new machine.

Standard boom and optional worklight guards offer great protection for vulnerable components in hazardous applications. JCB’s Safety Lever Lock fully isolates this mini digger’s hydraulic functions to prevent unintended movement.

Our unique 2GO system ensures your mini excavator hydraulics can only be operated in a safe lockable position via two separate inputs.

An overload screen displays a bar chart from green to red, indicating whether the overload point is close or exceeded. Once the limit is passed, the buzzer sounds and the bar flashes to warn the operator.

A large track frame width and low centre of gravity helps the JCB 51R-1 to offer amazing stability.

This powerful JCB mini offers greater visibility than our outgoing JCB 8050, ensuring easier, safer trench digging and manoeuvring. This is thanks in part to a 70/30 front screen split.

All dig end and dozer greasing intervals on a JCB 51R-1 mini digger are best-in-class at 500 hours, thanks to graphite impregnated bronze bushes; needless to say, this saves you time and money.

An open frame undercarriage with sloping track legs makes cleaning easier.

There are no plastic external body panels on the new JCB 51R-1; instead there’s 100% high strength pressed steel bodywork.

Colour-coded hydraulic hoses make for easy identification, while dozer hoses are simple to replace because they terminate at the bulkhead.

The wide-opening steel bonnet and external fuel indicator make it easy to fill this mini excavator’s tank from ground level. Opt for a refuelling pump with auto stop function to reduce spillages and increase safety.

Remove two bolts to lift out your digger’s entire cab floor, giving you full access to the main control valve spools, hydraulic connections, and many other components for inspection or replacement.
