Excavator Hitachi ZX 450 description and characteristics of the excavator Hitachi

Every field of activity when performing quite complex tasks nowadays uses special Caterpillar devices, because this type is the most stable, the most reliable and able to perform absolutely all types of work.

Description and functions

Such equipment is available in the model range of a large company Hitachi. Of the entire line, the Caterpilla r-Hitachi ZX 450 excavator should be highlighted. All manufacturers of this manufacturer, including this model, are very popular in the construction sector and in various large industries. All this is due to the versatility of equipment and high reliability. Due to these indicators, the Hitachi 450 crawler excavator is often used in the mining industry. It is worth noting that the model was developed, taking into account the proposals of all users, the devices have a lot of design features.

Distinctive elements of this excavator are the working bodies and crawler platform, as they were significantly strengthened. This has given the machine quite a lot of confidence, which is one of the most important features in case of difficult work. The working bodies received the latest hydraulic equipment, which was developed according to modern technology, which also had a positive effect on the service life of the machine.

Characteristic design features of the Caterpillar excavator should be highlighted: Hitachi 450:

  1. Rugged chassis.
  2. Optimal combination of speed and performance.
  3. Environmentally friendly power plant.
  4. Advanced technology in the hydraulic system.

The equipment is also noticeable in its class for other important virtues, namely the following:

  1. High level of operating comfort. The technique is equipped with a modern cab, which has a fairly spacious interior and comfortable control lever with a small stroke. Comfort during work has also been achieved through the installation of a comfortable adjustable seat and a large area of glazing, which provides an excellent view of the working area.
  2. High level of performance. The manufacturer achieved this thanks to several unique solutions, including: the new hydraulic system HIOS III; the new economical mode e; modernized electric unit with electronic control; functional hydraulic function, which can increase many operating parameters for a certain time of work.
  3. Convenient and easy maintenance and inspection of the equipment. In order to simplify the technical overview of the excavator, the manufacturer has placed all service points very conveniently.

Hitachi ZX 450 can be called the most successful model of the brand. This is due to many different characteristics, both design and technology. All this allowed the machine to win great popularity on the Russian market in a short time.

The design uses a classic scheme, which is indicated by the presence of an X-shaped middle beam. In addition, the excavator design is equipped with a mass of additional reinforcing elements, which means that the strength and durability of the equipment can be significantly increased.

The operator can perform all operations with maximum precision in moving the working plates. This is facilitated not only by the advanced hydraulic system, but also by the cab. The cabin is characterized by excellent visibility of the entire working area, which is achieved by a large area of glazing. Inside it has everything you need to create cheap working conditions. This is not only a comfortable driver’s seat, but also a number of unique design features and a fairly ergonomic layout of the main controls. The freedom around the operator’s feet has been increased, which also provides comfort when working.

In addition, the cab is equipped with a multifunction monitor, which displays all information about the status of the equipment in real time. Using this monitor, the operator can monitor fuel consumption, operating time, fluid temperature in the hydraulic system and cooling system, oil pressure in the engine and hydraulics, fuel level in the tank and many other parameters.

An interesting feature of this excavator is a special system that prevents the penetration and theft of the cab. In addition, the machine contains excellent safety systems and special features that can significantly improve the environmental friendliness of the equipment. The level of vibration and extraneous noise in the cabin is practically not felt. Reinforced glass is used in all model windows, which, in addition to visibility, has a positive impact on safety.

By default, Hitachi ZX 450 comes with a backhoe loader. Different types of arms and booms are available as options, varying in length. All of the offered implements are designed by the manufacturer.

The equipment has a fairly high maintenance. Despite its high reliability, sooner or later various breakdowns can occur. In this case, you will find the necessary spare parts at official dealers, which are more than enough in Russia. For long life, it is recommended to buy only original spare parts. It is worth noting that there is an opportunity to order spare parts over the Internet, which is very practical.

The body can be raised with switches in the cab or moved forward to ensure operator comfort. Increased durability of work equipment tines is due to the use of high line steel. The bucket is now equipped with Super-V tines, which provide a smooth plunge into the work material and increase the efficiency of the excavator. The ends of the bucket tines are socketed to eliminate gaps and idiosyncrasies during operation.

chassis

The Hitachi ZX 450 crawler excavator has larger diameter tines than the previous version. Crawler joints are 57% thicker than its predecessor for durability and longevity.

Hydraulic System

By utilizing the improved boom visibility system, the stick and boom can be lowered simultaneously and travel speed is increased by 15%. In addition, a positive effect is achieved by simultaneously turning and lowering the boom mechanism. The power of the skid increases by 8% due to the forced power. The manual manifolds have a larger diameter, which provides reduced power loss in the hydraulic system and reduced cycle time.

Operator’s cabin

The Hitachi Excavator 450 is equipped with an ergonomic cab with well-designed details. It has a voluminous interior, extended legs, and large, wide windows with reinforcements for strength and durability. This ensures comfort, increases concentration and reduces fatigue while working.

The operator’s seat is comfortable and has many adjustments. The backrest and headrest are designed differently from previous models. The dampers absorb vibrations and dynamic effects and increase the service life of the seat. The Hitachi ZX 450 cab, mounted on liquid-filled carriers, has the same features.

There is a monitor in the cab that displays machine status including fuel consumption and time. The Ant i-Vorin system, fall protection and exhaust filter rollover protection are fitted as standard.

Control system

As an option, the excavator is equipped with a reverse camera, the image from which is transmitted to the monitor in the cab. It is mounted on a counterweight that provides a wide view and eliminates blind spots.

When the Hitachi 450 starts up, it tests basic functions, and after a certain time, it prompts you to change the hydraulic and fuel filter. When these recommendations are followed, the risk of unexpected machine failure is reduced.

Short levers are tested with your fingers only, without having to remove your hand from the armrest. This reduces fatigue and increases labor intensity. The control system is interlocked with the untouched lever, eliminating accidental movement of the implement.

Application and what

In addition to the excellent features of the Hitachi 450, the advantages include ease of delivery. The oil coolers and radiators are mounted in parallel to each other, which guarantees disassembly and fast clearance cleaning.

The air cleaning filter has been moved to the door, which ensures high quality cleaning while reducing downtime. The air conditioning condenser and fuel cooler can be opened.

The large shroud area allows for uncomfortable maintenance, reducing operating time, complexity and material costs. Easy closing begins with the shock absorber.

It is automatically distributed to all mechanisms from the central lubrication point. The only exception is the standard work fund, which is lubricated separately. The points are accessible from the ground. A discharge tube is installed on the oil pan to which a hose is connected.

Swivel assemblies.

Hitachi 450 is a “backhoe” bucket as a standard implement. Optional boom and arm assemblies with improved indicators are available as well:

  • Vibroloader, vibratory rammer;
  • Hydraulic shaft, hydraulic fire;
  • Pallet Accounting;
  • Graifer – bucket and ripper.
