Hitachi ZX 330 LC crawler excavator technical specifications and description

Manufactured by a Japanese company, the Hitachi ZX 330 excavator has long taken a leading place among equipment of this kind. However, among the company’s products you can also find machines whose scope of application is industry, agriculture, construction, etc. The most popular model was released in the middle of the 20th century, and after 15-20 years a department was created for the production of equipment specializing in difficult working conditions and focused on construction and industry.

To sell the equipment in America, the Hitaki company signed an agreement with John Deere. Due to the high quality of the products, many models are very popular among Americans. Today, a small department created in 1970 has grown into a corporation and has more than 30 factories for the production of specialized equipment. Moreover, most of the factories are located outside the country of origin.

Features and Benefits

The Hitachi ZX 330 excavator is rightfully considered the most powerful machine from the entire model range of the company. Special reinforcement of the structures gave the equipment reliability and endurance, and therefore it can be used under difficult working conditions and successfully perform the assigned tasks. The reinforced part is also the steps located on the side of the machine. The level of safety is increased by installing protection on the front section of the boom, as well as rubber plates on the supports.

Hitachi ZX 330

The characteristics of the Hitachi ZX 330 excavator call into question whether the machine belongs to the middle class, and only high-class models can compete with it. The ZX 200 model, which is the previous version of the Hitachi ZX 330, is in great demand on the Russian market.

The mechanism of operation of the machine is quite intricate. This is due to the presence of a large number of automated functions and work steps. The Hitachi ZX 330 is adapted to particularly difficult working conditions when it is necessary to exert great effort to perform any type of excavation work.

However, this technique has a drawback - low mobility. The speed of the machine is only 5.5 km/h, which presents some inconvenience when transporting it to the work site. A tractor is provided for such purposes. But despite this drawback, the power and capabilities of the machine are still of greater importance.

In addition, the advantages of the Hitachi 330 include:

• reliability;
• strength;
• stability on any terrain and type of foundation due to the caterpillar drive;
• productivity - short deadlines are not a limitation for completing assigned tasks for any type of excavation work;
• environmental friendliness, because all exhausts comply with standards;
• safety.

History of creation

Some time after the creation of Hitachi Construction Machinery, partnerships were established with the equally well-known American corporation John Deere. This cooperation brought the company quite a lot of opportunities, including the supply of special equipment to the US market. Currently, Hitachi Construction Machinery has more than 30 factories, of which only half are located in Japan. These facilities produce almost all types of modern special equipment, however, it is excavator equipment that brings the greatest profit to the manufacturer. This type of machine is currently very popular all over the world. The entire model range includes machines both on a tracked platform and on pneumatic wheels.

One of the most powerful machines in the entire range is the Hitachi ZX330LC crawler excavator. Its distinctive feature from other models is its reinforced design, which makes it suitable for use in rather harsh production conditions. In addition to strengthening the side steps, the manufacturer installed additional boom protection and support plates made of high-strength rubber.

It is worth noting that this excavator is a representative of the middle class of special equipment, however, its overall dimensions and the operational power of the power plant raise some doubts about this. It is due to this that the Hitachi 330 model is the best in its class and has absolutely no competing models.

If you look at this machine from a technical standpoint, the excavator turned out to be quite complex, both in terms of control and in terms of further maintenance. But all this is compensated by resistance to high loads and doing a fairly large number of different jobs, which is due to the extensive range of additional attachments.

The main disadvantage of this excavator is its immobility. Its maximum movement speed is only 5.5 kilometers per hour, which is why the equipment is not able to independently reach objects. A special tractor is always used for transportation. But again, this is not such a big problem, because this is compensated by very high power indicators and a wide range of tasks performed. In addition, the manufacturer has endowed the car with other positive qualities: the equipment has a fairly high level of safety, the amount of toxic emissions into the atmosphere has been reduced, and the car can also boast of its efficiency. An excavator is an ideal option for doing any kind of earth-moving work with short deadlines for delivery of the object. The tracked platform has optimal dimensions, which ensured high stability of the machine on rough terrain and even in sticky areas.

Excavator Hitachi 330

Hitachi zx 330 belongs to the medium weight category of construction earthmoving equipment. Its developer is the Japanese corporation Hitachi Construction Machinery Co.Ltd. The technical characteristics of the Hitachi 330 excavator are determined by its power, functionality and the tasks for which this machine is manufactured.

Similar construction equipment is used in quarries and construction sites to develop pits and other recesses. Heavy earthmoving machines operate at unloading sites where various bulk materials are loaded and unloaded. The Hitachi 330 excavator is adapted to difficult working conditions, and in terms of performance it can compete with some high-class machines.

With a boom length with a canopy (bucket) of 11 meters, the excavator digs a hole of 7.4 meters and, if necessary, lifts soil or other cargo to a height of 3.2 meters. The volume of the digging bucket is 1.15 cubic meters. m. Most of the processes performed by an excavator are automated.

Chassis

The developers paid special attention to the chassis. It was tested under extreme conditions, when temperature changes are normal. The beams are made of square pipes and protect the base of the machine. The central frame is also protected from damage. The rollers and top brackets are enlarged, which has a positive effect on their durability. The only drawback of such developments is the increase in the mass of equipment.

To increase service life, the basic assembly includes three protective covers for the tracks. They prevent links from separating or breaking, especially during turns.

• Hitachi ZX 330 is a reliable machine for excavation work. And the additional weights make it truly universal. All Hitachi special equipment is distinguished by good production characteristics and high reliability.

The Hitachi 330 excavator is adapted to difficult working conditions, and in terms of performance it can compete with some high-class machines.

Ease of operation and maintenance

If it is necessary to get to the nodes and main elements, the operator himself can do this without experiencing any inconvenience. The mesh prevents dust and dirt from getting from the working platform into the internal working parts, and the elements of daily control are concentrated in one functional unit. The frame of the machine is also reinforced, which guarantees long-term operation without the need for major repairs due to mechanical damage. Consumables and liquids retain their functions and qualities for a long time without the need for replacement.

The latest models feature multi-function displays that help the operator monitor the work process. In addition, the cabin windows are made of tempered glass, they increase the viewing angle and guarantee safety in emergency situations.

Attachments

Return to navigation

Purpose

As described earlier, the Hitachi 330 can use a fairly large number of additional attachments in its work process. This list includes the following equipment:

1. A type of earthmoving bucket. The equipment can be equipped with several types of buckets, namely a bucket designed for digging pits, a bucket designed for planning a working area, and a bucket designed for digging trenches. The latter differs from the others only in its width. Such buckets are usually quite narrow. In the basic configuration, the excavator has the first bucket, since it allows you to perform a lot of different tasks related to earthworks.
2. Hydraulic breaker. Almost all modern equipment can be equipped with this equipment. This unit is intended for the destruction of concrete or reinforced concrete structures. This is precisely his main task. However, a jackhammer is often used in road repair work, where it is used to open the asphalt layer of road sections. Some models of such equipment are equipped with a hydraulic rotator, which allows for more precise and accurate work.
3. Hydraulic shears. This equipment is a kind of analogue of a jackhammer, as it is used to perform the same tasks. This unit is most effective in destroying concrete containing reinforcement. This is explained by the fact that the hydraulic cylinders of the jaws allow cutting through iron and steel rods. Just like the hammer, some models have a special rotator.
4. Hydraulic drilling equipment. This type is indispensable in drilling operations. But it is worth noting that the equipment can also be used to loosen solid masses of soil and rocks. Screws are available in various diameters and lengths.
5. Ripping equipment of single-tooth type. As is clear from the name, such a unit is used for loosening hard soil, rocks, and, well, for loosening minerals.

Fuel consumption formula for a tractor

If it is necessary to convert fuel and lubricant consumption rates into volumetric units of measurement, liters, the following ratio should be used. The FD-500 road milling machine spends 10 liters of fuel on its productivity much more than previous devices, but the unit with parts from MTZ-82, which consumes the largest amount of fuel, is the Amkodor 8047 milling machine.

Scope of application

The manufacturer has introduced a large number of modern technologies, systems and innovative solutions into this model, which has a positive impact on all the qualities of the excavator. This type of equipment is indispensable when performing work on small construction sites, parks or residential areas, inside tunnels, and is suitable for digging pits and trenches or removing snow.
