Scope of application of JCB backhoe loader

In Moscow, renting a JCB excavator is in demand in a variety of industries. This technique is used on:

• utility companies, for maintenance of communication systems and local areas;
• construction sites, both for performing main and auxiliary works;
• manufacturing plants, warehouses and terminals.

The versatility and compactness of such equipment makes it indispensable for both periodic and permanent work. That is why we have it in sufficient quantities in our fleet.

This technique has proven itself especially well when carrying out loading and unloading operations. Therefore, it is often rented specifically for such tasks.

Application area

The first excavator model rolled off the assembly line back in 1977. It is still produced today, and the design is constantly being changed. The manufacturer regularly uses new technologies and advances in the field of mechanical engineering in production. proudly declares that this model is the most common in the world.

The popularity of the application is associated with the reliability of the units, high performance and versatility. JCB 3CX is effectively used on construction sites, warehouses, far from highways, public utilities, and in aggressive environments.

Benefits of renting a JCB

Even seasonal and long-term rental of a JCB backhoe loader has its advantages:

• the company providing this service is responsible for the condition of the equipment;
• all issues related to the selection of personnel, remuneration, as well as professional development are also the responsibility of the lessor;
• the cost of such services is significantly lower than the price of maintaining and purchasing machines of this class.

Seasonal and long-term rental services have long become a global practice for most large companies. They have long calculated the benefits of operating other people's machines and compared them with the costs of using their own equipment.

Before leaving to order, the backhoe loader undergoes a thorough technical inspection, and its operator undergoes a medical check. You can be sure that the work you need will be done efficiently and on time.

Technical characteristics of loaders

Skid steers: This category includes 3 models - 403, 406 and 409.

403. The smallest multifunctional machine in the range.

Compact, mobile in confined spaces, with an open cabin without glazing, travel speed = 15 km/h, ground clearance = 200 mm.

Standard equipment: agricultural tires, mechanical bucket fastening.

406. Cabin with panoramic glazing. JCB 406 is equipped with diesel. Kohler engine power = 49 hp. With. Weight = 5020 kg. The machine is ideal for simultaneous use of front and rear attachments.

All other standard sizes of loaders differ from each other in power, lifting capacity, basic and optional equipment.

Engine

A significant advantage of the excavator is the Perkins diesel engine. The economical and high-performance power plant has four cylinders and a displacement of 4 liters. It produces peak engine power of up to 100 horsepower and torque of up to 400 Nm even at low speeds. This allows you to reduce fuel consumption to a minimum without loss of equipment performance. Depending on the modification of the excavator and the type of work, from 6 to 15 liters are consumed per hour.

The main advantages of the power plant:

• high torque even at low speeds;
• a water filter is provided;
• The oil filter has a counter-flow valve. This keeps the oil clean for a longer period of time and ultimately reduces maintenance costs;
• The air flow filter has an automatic cleaning system.

In addition, the engine is equipped with a heating system, which allows you to start quickly even in very cold weather. There is an effective cooling system and turbocharging. The latest JCB 3CX models have an improved fuel combustion system. Compared to previous versions, it has become much more efficient, which made it possible to abandon the exhaust system particulate filter. As a result, it was possible to achieve a reduction in fuel consumption.

Another innovation is the TORQUE LOCK option. The technological innovation allows reducing fuel consumption by a quarter and increasing travel speed by approximately 10%.

Operation, maintenance

For ease of maintenance, all important components of the power unit, transmission, and hydraulic system are located on one side. This facilitates inspection and reduces the time required for the operator to check the technical condition of the machine.

• The hood tilts completely forward without dismantling other parts or components.
• The battery is placed in front of the car, which allows you to quickly control the electrolyte level and its density.
• Lubrication of hinge units, refueling or changing technical fluids is carried out from ground level, which eliminates the use of lifting platforms or trestles.

The loader does not have an air pre-filtration system. Cleaning occurs due to the release of exhaust gases from the exhaust pipe. This system extends the life of the air filter until scheduled replacement.

Thanks to the hydraulic oil fine cleaning system, the working fluid change interval is increased to 5000 operating hours.

Modifications

There are several different modifications of the excavator on the market. They differ in configuration and set of attachments:

• JCB 3CX is the basic delivery option;
• Eco – the model is equipped with an economical engine. There is a special operating mode – “eco”;
• Super – compared to the basic configuration, the front wheels have a slightly larger diameter.

In addition to the ones listed, manufacturers also offer other modifications: Sitemaster, JCB 3CX Super Sitemaster, Sitemaster Turbo, Sitemaster Plus, Sitemaster Turbo Plus, Pothole Master, Contractor, Turbo.

One of the features of all the models under consideration is the ability to quickly replace attachments depending on current requirements. In the front part you can install forks or various types of buckets: deep, classic, conical, for digging ditches and others. The design of the rear carriage makes it possible to move the attachment to the side.

Standard Attachments

In basic models, a jaw bucket with a volume of one cubic meter is installed in the front part. Thanks to this, the JCB 3CX backhoe loader copes with the tasks of a front loader without any problems. With the help of such equipment, an experienced specialist will load a 7-cubic-meter KamAZ truck in four minutes, no more.

As for the performance of the rear bucket when digging pits, a lot depends on the depth of the excavation. On average, during an eight-hour work shift, an excavator operator will be able to remove at least 100 cubic meters of soil. In cases where simultaneous loading is required, the length of the dug trench will decrease by approximately 10%.

Price, analogues

Those who want to buy a new JCB 3CX will have to pay about 80 thousand dollars for it. The buyer must take into account the exchange rate, equipment and supplier.

A second-hand model will cost 25-40% less. It all depends on the year of manufacture, the technical condition of the model, and the basic configuration.

Analogs with similar characteristics: backhoe loader JCB 14M2WM, JCB 4CX, 4WS SM, TARSUS ElAZ 880 and 883, LiuGong CLG 777A, Komatsu WB 93R-5, Cat 432E.

Operating Parameters

The loader is produced both with two driven wheels and with all-wheel drive. Metal parts are shot blasted and coated with a coating system that protects the steel from corrosion, abrasives and aggressive chemicals.

Specifications

Power unit

Initially, a Perkins 1004-40T engine was installed on the car. This is an inline four-cylinder turbocharged diesel engine.

• In the latest models it was replaced with a motor of our own production. Its design is copied from Perkins.
• The new diesel engine was equipped with an electronic system that controls fuel injection, which reduced fuel consumption and reduced exhaust toxicity.
• In addition, the engine design does not include a particulate filter. The free passage of exhaust gases reduces their return to the crankcase and increases the oil change interval.

Engine parameters

Additional Information! The car was equipped with TORQUE LOCK technology. It reduces diesel fuel consumption by 25% and increases movement speed by 10%.

Power transmission, chassis

Two types of gearboxes have been developed for the 3CX loader: Powershift, Syncroshuttle.

• They are both synchronized, but the first is equipped with a mechanical switch for speed and direction of movement.
• The second has an electric drive, a torque converter. The latter provides a smooth change of speeds in optimal torque ranges.

The manual transmission on the loader is 4-speed. The customer may be offered an automatic transmission with 6 steps, but their top speeds are approximately the same: 39.8 and 38.3, respectively.

The machine control system is made of a hydrostatic type. It uses the hydraulic fluid pressure generated by the main hydraulic pump. To ensure controllability regardless of the current operating mode, hydraulic oil is taken off through a priority valve.

In the event of engine failure, an emergency steering system is provided.

The wheels are braked by a disc mechanism operating in an oil bath.

• The brakes have a mechanical servo drive and a self-adjusting design.
• This combination ensures reduced pedal pressure and reliable operation in a variety of operating conditions.

In addition, the “wet” type is more durable, and the friction surfaces retain their integrity longer.

Hydraulic system

The base 3CX model only has an open center hydraulic system.

• For manual control of the actuators, 3 gear-type pumps are used.
• The first produces 58 l/min, the second and third work together, their total productivity is 71 l/min.

At nominal supply, the pressure of the working fluid is limited by the bypass valve within 25.1 MPa.

1. In loader models that plan to be used as a drive for stationary or hand-held hydraulic tools, a system with a closed center is installed.
2. It uses a piston pump with a capacity of 165 l/min in conjunction with Advanced EasyControl technology.

The pressure of the working fluid is maintained at the same level as in an open system.

To connect manual or stationary hydraulic equipment, the system design provides a separate outlet and a high-pressure hose 9 m long.

The latter is wound on a special drum, which reduces the likelihood of damage when working on site, protecting the hose when not in use.

Layout

JCB 3CX is made according to the classic design.

1. There is a bucket at the front for loading bulk materials.
2. Earth-moving equipment with support posts was placed at the rear.
3. The engine and hydraulic system are covered with a sloping hood that folds forward and removable panels that provide good access to the compartment for repairs and maintenance.
4. The slope of the shelter does not block the working area, allowing the operator to fully control the loading process.

Dimensions

The mass and size characteristics of the model correspond to the operating parameters of the excavator. The wheelbase and track width provide the machine with stability on uneven or inclined surfaces. Embossed tires, all-wheel drive and differential lock significantly increase the tractor's traction.

Ladle

In the basic version, a jaw bucket with a nominal volume of 1 m³ is installed on the loader. Its geometric capacity is slightly smaller - 0.83 m³. Optionally, a larger bucket will be installed on the vehicle, but usually the standard one is enough to load the standard body of a medium-sized truck in 5 minutes.

A more interesting option would be to install a six-in-one bucket.

• They can dig, load bulk materials, and plan the territory.
• In addition, it is used as a bulldozer blade, a gripper for moving large loads, as a forklift in conjunction with removable mechanisms.

Earthmoving equipment is represented by a boom, a stick and a backhoe. The manufacturer offers buckets with widths from 230 to 950 mm. The customer installs the equipment depending on the intended types of work. In addition, the excavator can be equipped with 1525 and 1830 wide buckets for cleaning trenches.

The JCB 3CX is equipped with a standard or telescopic handle.

• In the first case, the digging and cutting depth is 4.24; 5.53 m respectively.
• The breakout force of the bucket will be 5.4 tf.
• When using the extended handle, the operating parameters are 5.46; 6.35 m, 5.3 tf, respectively.

To quickly change buckets or engineering tools, an innovative hydraulic quick-release carriage is provided. It allows attachments to be changed safely, in accordance with current and upcoming legal regulations.

Cabin

• The large glass area makes the machine easier to operate.
• Rear and side windows open partially or fully.
• Access to the cabin is provided from two sides, which reduces the time required for the operator to occupy the workplace.
• Door and window seals maintain good tightness, dust and sound resistance.
• The cabin has a heater and air conditioning system. Thanks to them, the car can be operated in hot or cold weather.

In addition, comfortable conditions for the operator are created by large rear-view mirrors, a sprung seat, a radio system, a radio with two speakers, cleaners, and washers for the front and rear windows.

Scope of application of the JCB 3CX Super tractor

The JCB 3CX Super is an excavator, loader and tractor at the same time. Therefore, the scope of services of the JCB 3CX Super backhoe loader is quite wide; it is most often used:

• during loading, unloading and processing operations;
• when improving landscapes;
• in agriculture;
• during excavation work.

This ensures a high level of profitability of the unit. It can be used for uprooting stumps, laying communication trenches, leveling the ground, clearing areas of debris and snow, laying foundation pits and other construction work.

Criterias of choice

When choosing the right model for purchase or rental, you need to consider several parameters:

• ZX or HT arm model and boom lift (Standard, High Lift, Super High Lift). ZX models can be equipped with a standard or high lift boom, and HT models can be equipped with a standard or extra high lift boom;
• standard or quick-release carriage - when installing a quick-release carriage, the load capacity is reduced;
• density of uncompacted material, (kg/m³) and bucket fill factor, (%).
  For example, 1 cubic meter of loose snow weighs only 200 kg, and its filling factor = 110%. Minerals weigh more, for example, a cubic meter of shale and magnetite weigh 2800 and 3200 respectively, at 100% filling. And barley, wheat or fertilizers weigh from 600 to 1000 kg/m³, but will fill only 85% of the volume.

Application of various models

Miniature models have certain specific applications, for example, the JCB 403 easily maneuvers on various farms or in garden centers.

The JCB 406 is ideal for utility applications, combining a snow blade with a rear sand spreader.

Attachments for the 403 and 406 include road brushes with or without rotation, and a shrub and tree shredder.

The use of medium and heavy loaders is advisable for the following jobs:

• loading of bulk materials: construction waste, soil, crushed stone, grain, silage and other agricultural products;
• earthworks: digging pits, ditches, trenches and canals;
• Men at work;
• transportation of various cargoes;
• logging using log grabs;
• removal of snow and ice, clearing and removal of debris;
• planning of territories with bulldozer dumps;
• dismantling of buildings and structures.

Depending on the working conditions, you can purchase suitable tires, which are presented in 12 options.
