The British company JCB is known throughout the world thanks to its tracked and wheeled construction equipment of high quality. A special place in the assortment of the company is the backhoe loaders. One of the most famous models of such equipment is a JCB 3CX Super. The bus is equipped with brand diesel engine.

Unlike most manufacturers of construction equipment JCB company pays much attention to design and ergonomics of its products. In this article we will look at the excavator-loader JCB 3CX Super more details. Will help us in this user manual and reviews the actual statements.

A Little history

Firm JCB was one of the first manufacturers of backhoe loaders. The «firstborn» of the company issued in 1954, called Major Loadall MK. It is a conventional tractor with a Fordson motor, cable, loader and the attached excavating equipment. The conveyor then descended 550 units.

Since 1956 has been the release of a new model, called the Hydra-Digger. It featured a more long excavating equipment. Until 1960, these models were produced about 1800. At the same time, they began to develop their own chassis, which led to the creation of model JCB4. It was the first backhoe loader which was painted in the signature yellow color and had a seat that rotates 180 degrees. Over three years of production it sold fifteen thousand copies.

For the period from 1961 to 1967 from the conveyor descended about 7,000 models JCB 3, which differed a moveable carriage, the supports and the new excavating equipment. In 1963, the model made some changes. In particular, it has been installed swing door, an elongated handle and a new engine (Fordson or BLMC). And the name was added to the index «».

A New generation, released in 1967 under the name JCB 3C II, was a real survivor. It was produced until 1980. For thirteen years, has sold about 40,000 copies. Made this version of a curved arrow and a sliding door. Later modifications have got semi-automatic transmission and a pneumatic boom.

The Next survivor has been put into production in 1980. His name was JCB 3CX. The application of the claw of the bucket allowed this version to dig holes to a depth of 5.53 meters. Previous modification was limited to four meters. Model 3CX produced 11 and sold around the world in the amount of 74 000 copies. It is so reliable that to this day serves faithfully on construction sites.

In 1990 appeared backhoe loader JCB 2SKH, which is the wheel formula 4 x 4 x 4. And 1991 was a turning point for the company. Model 3СХ has been completely redesigned, starting with the chassis and finishing with the design. In parallel, the firm began to produce a powerful all-wheel drive model of the JCB 4CX, which had a coherent rotation of all wheels and the so-called ‘crab move”.

In 2002 the company has relied on design. She introduced their flagship model of the servo and the Powershift transmission. And 2005 saw the release of the updated model with a solid hood, new hydraulics, a private engine and a number of other less significant changes. Here began the story of our today’s hero.

Cabin

Like all his colleagues, JCB 3CX Super has a spacious rounded booth. Its characteristic feature is a tinted glass and no crossbars. This appearance became one of the symbols of the products of the British brand. Cabin design came out very good and convenient. However, there is a disadvantage – in favor of aesthetics, all the Windows are glued in the openings. Considering specifics of work of such equipment, the risk of damage to the glass is quite large. And his replacement is now the laborious and lengthy process. Excavation and loading of the boom outwardly in harmony with cab and chassis.

The Hood

Backhoe loader JCB 3CX Super has become the first model, which boasts a sleek one-piece hood. Earlier the firm were commonly used three-piece hood. New technology not only gives a more finished appearance, but also is useful from a practical point of view. Now when you raised the hood access to the engine compartment is not what is not restricted. The exception is unless the radiator and the battery, for that you need to remove the grille.

Motor

As already mentioned, one of the main distinguishing characteristics of the excavator loader 3CX Super is the engine. It was designed specifically for this model. Engine JCB 3CX Super, according to the company, virtually from idle speed has a huge reserve of torque. In the design of cooling systems and power the motor was made a lot of original solutions. So, set the filter-water separator. It picks up the moisture trapped in the fuel. The oil filter is equipped with a counter-flow valve. It holds the oil in the casing when the shut-down motor. This solution not only makes the service more comfortable, but also allows you to run the motor on clean, filtered oil.

The air supply System has received a self-cleaning filter. The air intake at the same time issued a little to the side. This allows you to make the incoming air more clean and cool. About the serviceability of the motor alsocare – all service points are on the left side. So walk around the excavator to get this or that item is no longer needed.

Interior

Inside the cabin everything is strictly kept and very comfortable. The dominant colours – black and grey. Along with the window tint they give the interior a certain elegance. The layout of the interior decoration has not changed since 1997. And it’s not an archaism, and time-tested convenience and ergonomics.

The cabin has two jobs. One of them is intended for the operator of the loader. The steering column was a bit “thinner”. It has two steering levers. The first controls the transmission, and the second – lighting. Under the steering wheel there is a panel of indicators. It is crowned by the emblem of the JCB. Turning the chair 180 degrees, we get on the workplace of the excavator.

Is performed by traditional passenger cars scheme. On the right is the glove box, and the left – instrument panel JCB 3CX Super. Reviews of people who happened to work on this technique show that deserves special attention is the ventilation system. First, the diffusers are scattered throughout the cabin, they do their task perfectly. And secondly, the operator has the ability to open the rear window.

Chair

In this technique special attention is paid to driver comfort. After working on the backhoe loader is quite complicated and responsible. The set of adjustments the driver’s seat is not inferior to modern cars. Its height is modified in three ways: the chair, front and back.

With compressor, you can adjust the level of pressurization separately on the lower part of the back and on the top. For comfortable work in the cold season there is electric heating. To get comfortable in the chair JCB 3CX Super can absolutely anyone. With the driver’s seat offers excellent visibility. Front wheels and loader arm are clearly visible.

Administration

In the budget version control bucket and loader is operated using simple levers. On more expensive models it rests on three controllers. One of them is responsible for the loader, and the other two – for the excavator. Joysticks take over part of the functions of the pedals. This opens up for the driver to work, turning the seat to the side. Affordable version control excavator rests on two levers. The right is responsible for the rotation of the bucket and lifting/lowering the boom, and the left – for the motion of the bucket and boom swing.

The Pedal in this case is only responsible for one function of the machine JCB 3CX Super-telescope. How to adjust telescopic boom extension? Quite simple. As the reviews of experts, pedals work well. And if you include the appropriate switch, you can assign them another function – shift the carriage of the excavator. This is very useful, especially in urban environments.

The Administration also supports does not pose any difficulties. It is done with a lever near the instrument panel. This is another highlight of this model. Another feature-the lack of breaker and wiring under it. During a simple movement of the arrow is blocked by a lock that can be unlocked by using a special pen. It is located near the Cup holder. A toggle switch activates the leveling system of the bucket, which prevents its contents from spilling.

Drivetrain

We have already mentioned that the model 3CX Super is equipped with a semi-automatic Powershift transmission. Depending on modification, it can be a 4 — or 6-band. Another difference between the cheap versions of the expensive – no function «crab moves”. But for all the variations available the possibility of coherent rotation of 4 wheels. It also is activated using a special switch. Shall enter into force as soon as the wheels are aligned. This option greatly increases the maneuverability of equipment, allowing you to comfortably work in cramped conditions.

Drive

Backhoe loader 3CX Super has all-wheel drive. The transition between rear-and all-variant is carried out both manually and automatically. In the latter mode all-wheel drive is switched off if a 4th transmission. This allows you to extend the life of the transmission and save fuel.

By the Way, norms of consumption of fuel on the JCB 3CX Super, according to the manufacturer, are 9-15 l/h. It all depends on the type of work. When the speed of the device decreases and activates 3rd gear, the drive is automatically changed to full. Shows the user manual for the JCB 3CX Super, it is desirable to include all-wheel drive when working with a loader. In this case, greatly increases the load on the front axle.

Agility

Steering system hydraulic model. At the unplanned stop of the motor actuates the system emergency steering. The design includes two modes: a rotation of two or four wheels. The first option is mostly used when riding on common roads, and the second – when working in cramped conditions and manipulation of goods. The steering wheel from lock-to-lock turns of 2.75 turns. Characteristics of the turn without brakingwheels: diameter outer wheels-9,35 m, on the edge of the bucket – 11,15.

At the same time rotate with the braking of the wheels more compact. In this case, the diameter of the outer wheels – 8 m at the edge of the bucket – 9.5 in. Tires JCB 3CX Super are standard for products of this brand and have dimensions 16.9 x 24.

Brake

Much attention the developers paid to the brake system. As a result, when the pedal is pressed it is possible to obtain sharp and clear, but a predictable response. The brakes are very reliable, but their sharpness is to get used to. When driving on ordinary streets is recommended to wear seat belts and to use the regime of “floating away”. It eliminates the vibrations of the fork of the forklift, which can undermine the entire apparatus on the bumps.

Conclusion

In General, as shown by the feedback of the backhoe loader 3CX Super, even in cheap models is commendable. And the reasons are at least three: a comfortable cabin, excellent performance, bright appearance. Spare parts JCB 3CX Super are quite expensive. However, this is quite normal given their quality and the manufacturer level. Moreover, to bring down any node, backhoe loader, you should still try.
