JCB 3CX backhoe loader technical specifications and description

The most popular model of the manufacturer JC Bamford Excavators Ltd is the JCB 3CX backhoe loader, which has gained quite a lot of popularity in its class on the global market for special equipment. The development of this model took three years. The last final stage for the backhoe loader included about 600 different tests and tests, which the equipment completely coped with. However, the brand chose not to end there, but to additionally test the prototypes at specialized sites and stands, only after which the machine was put into mass production.

Description and features

British specialists were able to achieve optimal efficiency and payback indicators, which became a record in this class. A large number of modern technologies were used, which had a positive impact on the environmental friendliness and efficiency of the power plant. Thus, additional fuel economy was increased to 16 percent, and the level of toxic emissions was noticeably reduced. It is also worth noting that this also affected the overall performance of the equipment, since the machine is capable of doing any work for quite a long time without stopping to refuel.

But this is not all the advantages of this model. Great popularity is due not only to excellent performance characteristics, but also, importantly, versatility. The JCB 3CX backhoe loader can be used in even the harshest conditions and can perform a variety of tasks with optional attachments. The machine uses a pneumatic wheel chassis of equal size, which provides it with high cross-country ability and the ability to work in difficult places. The excavator is equipped with two drive axles and a special “track to track” function, when activated, the front and rear wheels can be turned simultaneously in different directions. Thanks to this solution, it was possible to significantly increase the maneuverability of the model. As a result, the JCB 3CX is often used in environments where work space is limited.

This machine is designed to work with any type of soil, as well as for processing stones, sand, crushed stone, coal and other similar materials. Optionally, the backhoe loader can be equipped with a conventional frontal bucket, two jaws and forks. The rear equipment also has its own configurations: either a simple boom or a telescopic one is installed.

Under the hood of the car there is a four-cylinder diesel power unit of the 1004-40T brand, the development of which was carried out specifically for this type of special vehicles. The key advantages of this power plant are the following:

1. The engine has a large reserve of torque, starting from its idle speed.
2. There is a counter-flow oil filter valve that keeps oil in the filter housing when the engine is off. Thus, the subsequent start-up of the unit is carried out on clean oil. This also makes maintenance even more convenient, since no oil is spilled when replacing this filter.
3. The fuel system is equipped with a special water separator, thanks to which water is separated from the fuel, which ensures proper and long-term operation of the engine.
4. The air supply system was equipped with a self-cleaning filter. The air intake has been moved to a more suitable location. This is done to ensure that the engine uses cold and clean air, which also affects its proper operation.
5. Lubrication points are conveniently located, which further facilitates the maintenance process of the backhoe loader.

The Perkins 1004-40T is characterized by high performance and at the same time low fuel consumption. The engine has a water pump, a turbocharging system and a heating device, which is very useful when operating in fairly cold conditions. It is worth noting that some versions of this backhoe loader are equipped with an atmospheric engine.

The latest modified versions are more equipped with a diesel particulate filter, which causes increased back pressure on the engine. An alternative to this was an improved combustion system, which had a positive effect not only on increasing power, but also on fuel economy.

Optionally, the machine can be equipped with a torque locking system called JCB TORQUE LOCK. This system is activated automatically when operating in fourth gear (if a Powershift gearbox is installed) or when mode “A” is turned on (if an Autoshift gearbox is installed). This system allows you to reduce fuel consumption by 25 percent and increase the speed of movement of equipment uphill by 10 percent.

The gearbox was also designed specifically for the JCB 3CX. There are two types of gearboxes, namely Powershift and Syncroshuttle. Let's look at each in more detail:

Powershift gearbox. This gearbox has reverse and one shift lever located on the steering column. Only four passes.

Syncroshuttle gearbox. This gearbox is electrically controlled and has a hydraulic transformer, which ensures smooth gear changes when moving.

The backhoe loader has an advanced braking system that provides effective braking. The brakes are disc type and have automatic adjustment. Due to the fact that they use an oil bath, their service life is quite long.

It is also worth highlighting the hydraulic system with an open center, due to which optimal speed and power of the hydraulic drive is achieved. Its key feature is the automatic selection of the necessary parameters depending on the degree of load. Thus, the technique becomes even more effective.

The manufacturer also took care of the comfort and safety of the cabin. Its design is made of high-strength steel and is fully compliant with ROPS/FOPS standards. The entire glazing covers an area of ​​6.5 square meters, which provides not only excellent visibility of the work area, but also an increased level of safety. The following additional equipment is installed in the cabin:

1. Advanced EasyControl servo control system, which improves the efficiency and productivity of equipment when doing earthmoving work.
2. Alternative hydraulic control system AdvancedControl, operating in semi-automatic mode.

The cockpit instrument panel contains everything necessary to monitor the current state of the machine, namely coolant and oil temperature sensors, fuel level sensor, oil pressure sensor, tachometer and much more. The cab design is also equipped with two halogen headlights, four working headlights and two rear lights, thanks to which the machine can work in conditions with rather poor visibility. In general, the cabin was comfortable and very successful in terms of design, but in addition to numerous advantages, it also has its disadvantages. The weak side of the cabin turned out to be the not entirely successful placement of glass that is glued into the openings, which is why various damage often appears, and their elimination takes a very long time.

Volvo CE / SDLG – East orientation in action

As you know, Volvo Construction Equipment several years ago abandoned the production of motor graders and backhoe loaders under its own brand. Having closed production plants for these machines in Europe, North and South America, Volvo created new, lower-cost solutions based on its subsidiary, the Chinese company SDLG .

SDLG offers the B877F backhoe loader, available with both a standard and telescopic boom. Developed in collaboration with Volvo, the new B877F features a state-of-the-art hydraulic system made in China for smooth, easy operation. Thanks to it, the operator can perform several work operations simultaneously, and the additional hydraulic line facilitates the connection of attachments, including a hydraulic hammer.

The main drive in the car is a Weichai diesel engine with direct injection, water cooling and turbocharging WP4G95E221 with a power of 95 hp, produced by the Chinese engine company Weichai Power under license from Deutz. Weichai produces about half a million diesel engines per year in the power range from 100 to 3000 hp. More than a dozen Weichai Power service centers already operate in Russia, and their number is growing. Weichai claims that their engines are not demanding on fuel quality, are economical, comply with environmental standards, operate successfully in extreme conditions even under prolonged maximum load, and generally demonstrate high reliability, while significantly outperforming the world's leading brands in product cost.
