Device

All components and mechanisms of the JCB 220 excavator undergo long-term testing for strength and reliability, thereby ensuring the maximum service life of this equipment.

Increased strength characteristics are achieved through a durable turntable and welded X-shaped frame. The working parts of the excavator are made of highly reliable steel and are additionally reinforced. The use of internal strong partitions and an all-metal boom plane significantly increases the performance of the machine. The JCB 220 turntable is welded to the undercarriage planes, ensuring reliability even in extreme conditions.

Thanks to welded structures, the necessary reserve of strength is achieved during heavy operations. The model pays a lot of attention to issues of ergonomic work and safety. Hydrodamping of equipment and working parts reduces shock impulses, minimizing shaking and vibration.

Inspecting the engine compartment of the JCB 220 will not be difficult. The approach to the necessary units and components is carried out using pneumatics without much effort.

Numerous advantages distinguish this excavator from similar equipment. Among the key advantages of the model are:

• convenient controls and additional options (climate control, audio system, etc.);
• a comfortable operator’s workplace with a well-equipped and carefully thought-out seat;
• successful design that attracts attention and represents safety;
• automatic engine optimization mode;
• easy access to mechanisms and elements;
• large power reserve due to increased pressure in the hydraulic system;
• Plexus hydraulic oil filtration system with the function of additional hydraulic fluid purification, extending the oil change period;
• function of short-term increase in pressure in the hydraulic system by 10%, providing increased breakout force on the handle and bucket.

Special attention should be paid to the JCB 220 cabin. Features of this element are the presence of a heater with a device that prevents fogging of the windshield, levers of optimal length and an adjustable seat on a pneumatic cushion. The AMS control system constantly displays technical data characterizing the condition of the equipment on a monitor located in the cabin. This helps ensure maximum efficiency and fuel economy.

To expand the functionality and performance of the excavator, the manufacturer offers a wide range of attachments:

1. hydraulic hammer HM1760Q or HM1570Q;
2. standard fine toothed buckets;
3. standard buckets with ESCO teeth;
4. profiling buckets with teeth 1500-2000 mm;
5. stone cutting head RW100N;
6. crushing bucket CB70;
7. quick-release hydraulic carriage;
8. buckets for heavy work;
9. hydraulic shear MP200;
10. sorting gripper G700.

Price of new and used JCB 220

The JCB 220 model combines good characteristics with a relatively low cost. The average price of a used version in excellent condition is 2.2-3 million rubles.

Renting this excavator is very popular. An hour of operation of a JCB 220 will cost 1500-1600 rubles.

Analogs

The JCB 220's competitors are the Hitachi ZX 200 and Caterpillar 320 DL excavators.

Description and features

In its class, the model is characterized by increased reliability and durability. All elements of the excavator, in particular the power unit and hydraulic system, remain fully operational at temperatures ranging from minus 40 degrees Celsius to plus 40 degrees Celsius. Thanks to this, the equipment is especially in demand in countries with harsh climates. In Russia, the Hitachi 220 model can often be found on the sites of various construction organizations, which is explained by its unpretentiousness both in terms of the quality of fuel consumed and operating conditions, as well as low-cost maintenance. The increased stability of the excavator allows the machine to be used on slopes, soils with reduced bearing capacity, wetlands and other difficult to navigate places. This model is especially effective when performing various dismantling works.

In addition to its standard attachments (digging bucket), the excavator can be used when performing any operations and a lot of other additional units, among which are buckets of various capacities, hydraulic breakers, hydraulic shears, grab buckets, loosening units, vibrating tamping plates, drilling installations and many other types of replacement equipment. The manufacturer specifically used a quick-release fastening mechanism for this purpose, which allows you to replace the working equipment in a fairly short time without any particular difficulties.

The Japanese manufacturer Hitachi pays special attention to quality and performance when developing each of its machines. As a result, all manufactured products are famous for their excellent performance indicators, namely high efficiency, increased strength, high reliability, enormous service life of all elements and assemblies, as well as quite excellent power characteristics. These machines include the Hitachi ZX220 crawler excavator.

The model uses the innovative HIOS III hydraulic system, which is ideally combined with the installed engine. This allows for greater efficiency and reduced fuel consumption. The key features of this hydraulics are its fairly high lifting capacity, thanks to which the equipment is able to withstand very heavy loads during loading and unloading operations; improved smoothness of movement of working parts, which has a positive effect on the accuracy of the manipulations performed; several operating modes that set certain parameters for certain elements in order to achieve increased productivity.

The Hitachi 220 excavator is standardly equipped with a boom and handle, the length of which is 5680 millimeters and 2910 millimeters. With such working bodies, the equipment has very high maximum reach of the bucket. It is also worth noting that in comparison with previous models, this one is also distinguished by increased traction force and turning torque.

The manufacturer has significantly improved the control of equipment when moving independently. Thanks to these changes, the rotational speed of the power plant's crankshaft automatically increases when maneuvering and lifting, since to carry out precisely these actions requires an increased traction force of the unit than during direct movement.

The power part of the excavator itself includes a four-cylinder diesel engine of the AH-4HK1XYSA-02 brand. This unit was developed by another equally large Japanese company Isuzu. This engine uses direct fuel injection into the combustion chambers and a liquid cooling system. In it the camshaft is located at the top. In terms of environmental friendliness, the installation was also quite successful, since it fully complies with Tier II and Tier III standards, which allowed the excavator to enter the European market of special equipment. The main advantages of this engine are high structural strength, increased performance, reduced diesel fuel consumption, impressive service life, and maintainability.

It is worth highlighting the Hitachi 220 tracked platform, the frame of which is already made in the traditional X-shaped form. Its design has additional reinforcements, which significantly increases strength and reliability. The upper and lower frame reinforcements are monolithic slabs, whereas earlier models of excavator equipment used ordinary welded slabs. Their replacement had a positive effect on the stability of the structure to various shock loads and shocks, which could lead to deformation of the platform. The dimensions of the upper support roller brackets, as well as the support rollers themselves, have been increased in size, thanks to which the manufacturer has achieved increased durability of the track elements. The track links, like the central frame, were reinforced, which gave a total increase in strength by 35 percent. Each track is driven by a two-speed axial piston hydraulic motor and a planetary gearbox. This ensures their reverse movement. The drive wheels of the excavator sides are interchangeable, which allows you to save on equipment maintenance.

The excavator in its basic configuration has a counterweight, the mass of which is 5350 kilograms. This weight is quite enough to perform almost the entire range of work.

The model uses an automatic transmission, which allows you to select the required travel speed. In total, two speeds can be selected, these are 3.3 kilometers per hour and 5.5 kilometers per hour. Compared to its wheeled counterparts, this model is very slow, which does not allow it to independently reach objects, which is also typical for any other tracked special equipment. For these purposes, a specialized trailer and tractor are always used. The parking brake in this model is hydraulic disc.

Maintenance will not cause any particular difficulties and large financial and time costs for the owner. This is explained by several reasons:

1. The large hood and turntable side doors allow service personnel access to all critical components, including those that require regular inspection.
2. All service points were quite conveniently grouped, which makes it possible to reduce the time for replacing consumables, working fluids, and the time for lubrication of any components and mechanisms.
3. All components of the Hitachi ZX220 excavator are quite widespread and have a very affordable price.
4. Service intervals have been significantly extended.
5. High durability of all excavator design elements.

The machine has an advanced operator's cabin, which houses an on-board computer, a comfortable seat with full adjustment, a radio, air conditioning, a powerful heating system and controls made in the usual form of joysticks. Thanks to the use of high-quality sound-proofing and vibration-proofing materials, the manufacturer was able to significantly reduce the level of extraneous noise and vibration, thereby ensuring increased operator comfort. The cabin also features excellent visibility of the work area from the operator’s seat and a high level of safety.

Classification of Hitachi excavators

The model range of Hitachi excavators popular among builders is represented by the following main categories:

1. A small-sized mechanism (its professional name is a mini excavator).
2. Middle class units (200 and 300 series).
3. Large samples.

According to the method of movement, all of the listed vehicles are divided into tracked and wheeled models.

The factory designation of each type of excavator contains complete information about the category (you can use it to determine the type of chassis and the group to which it should be assigned). Thus, the Hitachi ZX330 excavator, for example, is a tracked model belonging to the middle class.

Machine structure

To understand the structure of this model of equipment, you should familiarize yourself with its design features. Any excavator from Hitachi consists of the following main parts:

1. Engine compartment.
2. Cabin to accommodate the operator with controls.
3. Working tool (bucket or lift).
4. Chassis.

Hitachi ZW220-5A front loader

Japanese-assembled Hitachi ZW220-5A wheeled front loaders began arriving on the Russian market at the end of last year. Why is the new product attractive to domestic operating organizations?

power line

Japanese engineers used a six-cylinder in-line Cummins QSB6.7 diesel engine as a power unit. The cylinder diameter and piston stroke of the internal combustion engine are 107x124 mm. The power output is 194 hp from a working volume of 6.69 liters. With. (at 2000 rpm) and torque 931 N.m (at 1400 rpm). Taking into account the ability of the special vehicle to operate in highly dusty conditions, the designers used a two-element dry-type air filter with a clogging indicator. The latter will allow you to avoid the operation of the power plant in air shortage mode, promptly warning the loader operator about the need to urgently replace the filter elements. The internal combustion engine power system is electronically controlled Common Rail. On the one hand, it is this type that allows you to optimize the operation of a diesel engine, including such an important parameter as fuel consumption. On the other hand, as practice shows, it is Common Rail that puts forward particularly stringent requirements for the quality and purity of fuel and is quite expensive to repair. Taking this circumstance into account, the creators of the loader included a multi-stage fuel filtration system in the design of the machine. Two fuel filters installed in series filter out suspended contaminants of varying purity. In addition to filters, the machine manufacturer (as specified in the operating instructions) requires the operator to perform a daily operation of draining water from the corresponding storage tank in the fuel tank. To drain the condensate, you must open the appropriate tap. One of the features of the power plants of machines designed to operate in highly dusty air conditions is an optionally ordered cooling system with radiators with a larger fin pitch. This technical solution makes it possible to reduce the likelihood of clogging the radiator honeycombs and, accordingly, ensure optimal thermal operation of the power unit. However, a reasonable question arises: is the heat transfer of a radiator modernized for high dust conditions reduced? As employees of the Russian representative office of Hitachi assured us, there is no need to worry about the temperature of the diesel engine, since the intensity of the radiator airflow (read “fan rotation speed”) is regulated automatically. We also note that Russian customers order a radiator with an increased pitch relatively rarely. Basically, buyers choose a cooling system with standard units. What is also important to mention when talking about the power unit is that the main difference between the Russian and European versions of the cars is the purity of their exhaust. Thus, Tier-3 standards are relevant for the Russian Federation, and more stringent Tier-4 standards are relevant for Europe. On the other hand, loaders supplied to the Russian market do not have an expensive particulate filter or other exhaust gas purification systems, which are very critical to the quality of fuel and oils. According to the designers, the car we are considering has an optimal combination of transmission and power unit characteristics, which allows us to reduce inefficient use of power to a minimum and optimize fuel consumption. The latter is very important for constantly loaded special equipment, especially given the steady increase in fuel costs. Fuel economy for the Hitachi ZW220-5A front loader is achieved by optimizing power transmission modes from the engine to the drive axles. In essence, we are talking about flexible, or more precisely, intelligent linking of the operation of the internal combustion engine and transmission in relation to the load. Three interconnected controllers are responsible for selecting the mode and controlling the power line of the loader. The first controls the operation of the internal combustion engine, the second is responsible for the transmission, and the third coordinates the operation of the first two. In this case, the control of the hydraulic line is under the control of the main controller. This is done, in particular, so that in a mode when the machine does not perform useful work on moving material (loading or unloading) and hydraulics, accordingly, are not involved, the entire power flow is redistributed to the drive axles. A few words about the features of the transmission used on the special vehicle. It has three operating modes. In the first, the operator shifts gears manually. This is necessary to perform a number of complex tasks where the automation may make an error, or forced engagement of one of the optimal, in the operator’s opinion, gears is required to perform a specific operation. The desired transmission stage (and there are five of them) is selected by moving the steering column switch lever to one position or another. If the automatic mode of operation of the transmission is activated (the control selector is moved to the “Auto 1” position), the loader moves using all stages of the transmission – from first to fifth gear inclusive. If the selector is in the second automatic position “Auto 2”, then the range is limited in the second gear (stages 2 to 5 are active). The first or second automatic modes are selected based on the operating conditions of the machine and the characteristics of the site where the work is being performed. As practice shows, in most cases, to ensure optimal operating speed of the loader, it is enough for the operator to set the gear reduction limit in the transmission to the second stage, that is, we are talking about the “Auto 2” mode. Let's briefly talk about the control of the Hitachi ZW220-5A. In the standard version of the machine it is lever. However, the option list also includes joysticks. The choice of one option or another entirely depends on the client’s financial capabilities and the need to use more modern controls. Let’s make a reservation right away: for Russia, simpler and more reliable levers are preferable. The loader cabin has a large glass area. On the one hand, this has a positive effect on the operator’s work comfort, on the other hand, it raises concerns that in winter, especially in the northern regions of Russia, the cabin will quickly get cold. As practice shows, the power of a standard stove is quite enough to create comfortable conditions for the operator and quickly clear ice from glass. At least dealers don’t put “dry hair dryers” in the cabin - there are no requests for this work. And who better than them to know the requirements of clients. All Hitachi ZW220-5A front loaders are equipped with a telemetric data transmission system. Consequently, clients have the opportunity, through their personal account on the Hitachi website, to receive information about the location of their equipment, its operating modes, including fuel consumption. Moreover, when the system generates “emergency” signals indicating the presence of certain malfunctions in the loader, the corresponding report is automatically generated and sent to the client and the dealer’s service department. The latter promptly responds to these messages, reducing equipment downtime for repairs.
