JCB 3CX - backhoe loader: technical specifications, bucket volume

The JCB 3cx tractor is the brainchild of British manufacturers JC Bamford Excavators Ltd. The history of the creation of this type of construction equipment is interesting. In 1945, Joseph Bamford opened his own workshop in Joseph Bamford's garage, where the master worked on the design of a tractor trailer. The product was successfully sold, and the proceeds were used to improve the design, which, as a result, made it possible to create a model of the MK 1 universal loader, which additionally featured an excavator bucket.

In the 60s, Bamford already had £3,000,000, which helped the master expand production. JCB offices are currently located on 4 continents. 18 factories supply products to 150 countries, with 11 of them located in the UK.

It is noteworthy that there is a wide range of JCB products, the most popular of which are the JCB 3CX and JCB 4CX models.

JCB 3CX technical specifications, weight

The basic model and its modification can be equipped with various attachments. These include buckets (standard, jaw, conical, deep, for digging ditches), and forks. The universal 6-in-1 jaw bucket deserves special attention; it digs, moves, loads, grabs, levels the soil and fills ditches. The maximum digging depth of the JCB 3CX excavator according to SAE (distance from the ground surface to the bottom wall of the bucket) with a standard handle is 4.24 m. For the 3CX Super model, this figure is 4.37 m. If the machine is additionally equipped with a telescopic handle, the digging depth will increase to 5.46 and 5.5 m respectively. Ground clearance (0.37 and 0.33 m) allows special equipment to work on uneven surfaces.

Purpose

The JCB 3CX model, again called the “troika”, is used to perform the following work: – leveling the territory; – preparation and construction of temporary roads; – digging trenches and pits; – transportation of large loads; – other landscaping and earthmoving work.

The backhoe loader works with any type of soil and easily processes stones, sand, crushed stone, coal and other materials. Thanks to its considerable maneuverability, the JCB 3CX feels confident in confined spaces and hard-to-reach places. Intuitive controls optimize workflows, reducing manual labor.

The JCB 3CX model is offered in several modifications, which are practically no different from each other in appearance. The difference between them lies in the design features. Thus, the JCB 3CX Super is equipped with a proprietary diesel engine, a modified chassis and enlarged front wheels.

again, the equipment configuration may change. The front linkage is sometimes supplemented with a jaw or simple bucket or forks, and a telescopic or simple boom is often installed at the rear.

Engine

The 3CX series equipment, which is intended for the Russian market, is equipped with 4-cylinder JCB Dieselmax 4.4 liter power units (Tier II or Tier III). The turbocharged engine found on the 3CX Super excavator is more powerful (92 vs. 85 hp on the base 3CX model) and has more torque (400 vs. 320 Nm). Depending on the operating mode, fuel consumption on 3CX varies from 6 to 10 liters, on Super - from 9 to 15 liters per hour. This efficiency is achieved thanks to increased torque in the lower rev range.

Maintenance and repair

The JCB 3CX tractor, whose dimensions ensure high maneuverability, was created by the English company JC Bamford Excavators Ltd (JCB).

JCB-3CX loader in operation

JCB 3CX is the most popular model of this brand, one of the best backhoe loaders in the world, created according to the special JCB Efficient Design program. Leading the construction equipment market, the manufacturer sought to ensure that its products were competitive.

Conclusion

The JCB equipment described in the article works successfully in Russia and has become popular among machine operators. This is a reliable assistant when performing construction, agricultural and repair work.

Modifications

There are several modifications of the 3CX backhoe loader. They differ from each other in configuration and the ability to install one or another attachment. The most popular is 3CX Super.

The main thing that distinguishes the Super model from the standard “troika” is the modified chassis and wheels of the same size. They provide greater maneuverability and load capacity, however, such additional advantages will only be needed if the special vehicle will mainly serve as a loader. At the same time, the basic excavator has better maneuverability due to its small front wheels. The turning circle at the edge of the bucket without braking for the 3CX is 10.4 m, for the 3CX Super it is almost a meter larger - 11.15 m. On the outer wheels, the turning circle with braking reaches 6.9 and 8 meters, respectively.

There are also differences in the cross-country ability of the equipment in question. The approach angle of the “classic British” 3CX is 66°, while its Super modification has 74°. The departure angles and at the top of the obstacle between the wheels do not differ so significantly: 20° versus 19° and 120° versus 118°.

Otherwise, the 3CX backhoe loader is no different from the Super model. Both special vehicles can be equipped with either a synchronized 4-speed JCB Syncroshuttle gearbox, which allows you to change gears without jerking, or a JCB Powershift gearbox with one gear shift and reverse lever on the steering column.

As an option, JCB 3CX backhoe loaders can be equipped with an SRS compensation system (softens and absorbs shocks), a Torque Lock torque fixing system (reduces fuel consumption by 25%, increases uphill speed by 10% and increases boom reach by the same amount) and the POWERSLIDE carriage shift function. The latter allows you to move the carriage with equipment in the transverse direction along the rear frame of the supports.

Axles, steering

The front and rear axles of the JCB 3CX Super are steerable, with all-wheel drive and proportional torque distribution.

Optionally, limited slip differentials can be installed.

Operator's cabin

It’s worth saying a few words about the cabin of the popular “Englishman”. The glazing area is 6.4 m2. The rear and side windows open fully or partially. The noise level in the cabin is the lowest among classmates - 73 dB. An adjustable seat with mechanical suspension, a convenient location of control levers, a radio system and a radio with two speakers, a heater and window defogger with three speeds, wipers and washers for the front and rear windows, large rear-view mirrors - all this creates comfortable working conditions for the operator.

Device

All JCB 4CX modifications are equipped with hydraulic power steering and 3 operating modes. The operator has the ability to turn 2 wheels, 4 wheels or rotate the wheelbase in the opposite direction.

again, all variations of the JCB 4CX have a JCB Powershift gearbox operating in automatic mode. The gearbox has 4 speeds. Thanks to this solution, operating the backhoe loader has been significantly simplified. At the same time, due to electrical control, changing gears on the JCB 4CX is smooth and soft.

This special equipment is characterized by greater operating efficiency in comparison with analogues. An important role in this is played by the hydraulic system with 3 EcoDig pumps, which provides excellent pressure and hydraulic flow at low engine speeds. This saves up to 15% fuel. At the same time, harmful emissions are reduced and wear on the power plant is reduced. The JCB 4CX has the best efficiency ratings in its class.

The model features JCB EcoRoad technology to improve driving performance. JCB TorqueLock technology, which is the company’s own development, significantly increases the efficiency of the equipment. Hydraulic speed control, which automatically disconnects the hydraulic pump in 4th gear, further reduces fuel consumption.

The JCB 4CX is designed for full-time productivity and comfort. A luxurious heated and air-suspension seat is just one of the features of the unique operator's cabin. It itself is placed on rubber shock absorbers and is insulated, which reduces vibration and noise levels.

Backhoe loader controls include an LCD panel with information about system problems, fuel level and machine operating time. Tinted glass provides 360-degree visibility for improved productivity and safety, while the innovative curved rear window gives the operator the ability to see directly into the trench while digging.

How much does a JCB 4CX cost new and used?

There is a wide range of JCB 4CX machines on the market. The price of the model is determined by the year of production, completeness and condition. special equipment from 2010-2011 with a mileage of up to 2000 km will cost 2.1-2.5 million rubles.

Weight, bucket volume

The excavator's body and components are made from high-strength, thick steel, allowing it to withstand high-stress workloads and maintenance costs. The tractor moves under its own power from object to object, spending a minimum of fuel and time, thanks to the JCB Torque Lock system, which fixes the torque, reducing the time for moving between sites.

JCB excavator: review of models

JCB construction equipment is used quite often today because it meets all the criteria for reliability and productivity. The JCB excavator has long been indispensable for digging pits, arranging construction sites, digging trenches, and constructing highways. What is the secret of the success of this manufacturer’s equipment?

JCB was founded in the middle of the last century in Great Britain. At that time, it consisted of one person who rented a small garage and began assembling a car trailer using a welding machine.

The founder of the company set himself the goal of achieving success and he succeeded. Ten years later the company switched to the production of construction equipment, and the annual turnover already exceeded 3 million pounds. The brand owner invested all the profits in the development of the enterprise and increasing capacity.

Today JCB has more than 8,000 employees involved in production and maintenance, and equipment is exported to 150 countries. The product catalog includes 300 items, including backhoe loaders, Loadall telescopic loaders, wheel loaders, tracked and wheeled excavators, wheel loaders, dump trucks, motorcycle and special equipment, hydraulic motors, etc. Official website of the dealership center in the Russian Federation https://www .jcb.com/ru-ru.
