Hitachi ZX-330 excavator review -

The Hitachi excavator is a reliable Japanese technology that has long proven itself on the positive side. The line of this manufacturer of earthmoving machines includes wheeled and tracked models. All of them have good build quality and show high performance for decades. The brand's worn and scratched tracked and wheeled excavators are as functional as those fresh off the production line.

Mini excavator Hitachi ZX17U-5A

The Hitachi ZX17U-5A miniexcavator is a tracked earth-moving machine whose dimensions are so small that one can say about it that only a shovel is more compact. At the same time, the equipment effectively copes with its task: it removes soil to a depth of 2190 mm and to a height of 3540 mm. The turning radius of the bucket is 3810 cm. These capabilities are sufficient to use the Hitachi ZX17U-5A in a wide range of earthmoving work.

All models of Hitachi excavators have no backlash in the joints of parts, which is explained by the high precision of assembly. Features of Hitachi ZX17U-5A:

there is protection for hydraulic cylinders and rods from mechanical impact;
Additional steel plates are installed on the bottom of the bucket;
The spacious operator's workplace is equipped with an LCD monitor;
reinforced platform side members;
a wide selection of attachments from the ZAXIS series, the assembly of which uses advanced bushings.

There is no perfect technology

Excavators from Japan also had a drawback - a rather hard seat. “I would give him a “four” and perhaps even a minus. You can’t understand this at an exhibition or in a showroom, but after a work shift you feel that the back profile is not made perfectly in the middle part. It's funny, but similar complaints are made about Mercedes, with which I initially compared our Hitachi, and in particular to the E-class in test drives. Apparently, it’s impossible to make a perfect technique.”

Several more facts that can be attributed to the machine’s shortcomings were stated further. But we will talk about them in the second part of the review .

The editors of “Excavator Ru” express gratitude

general information

HITACHI mini-excavators are often used for the needs of public utilities and perform work in the final stages of construction. In some cases, they can be used inside warehouses, if the floor covering allows. Thanks to the tracked base, the equipment feels comfortable on steep slopes and unstable soils. The compact dimensions of the turntable and the sliding carriage allow the equipment to work close to the walls of buildings and provide room for maneuver in limited spaces. The main advantages of small-sized equipment can be expressed as follows:

Compact dimensions.
High stability under peak loads.
Relatively good performance.
Increased cross-country ability and maneuverability.
Specific low ground pressure.

Of course, mini excavators also have some disadvantages. For example, the equipment has a low transport speed (about 5 km/h), a small excavation depth and minimal traction force on the edge of the bucket. As a result, machines cannot independently get to the place of work and develop soils of increased complexity.

Application area

Thanks to its compact dimensions, the equipment easily found its niche in the construction industry. Crawler mini excavators are ideal for solving the following problems:

Road works that do not interfere with traffic flow.
Improvement of surrounding areas.
Construction of foundations and pits for private residential development.
Elimination of accidents on utility lines.

This versatility is due to the wide selection of attachments that mini excavators can work with. This includes:

Front loader jaw buckets.
Hydraulic hammers.
Bulldozer blades.
Hydraulic shears.
Soil compactors.
Grab grips.

The HITACHI range of mini crawler excavators includes two series: EX and ZAXIS (ZX). Let's look at the technical characteristics of the most popular models.

Hitachi ZX-330 excavator review

Direct supplier of original and analog spare parts for road construction and agricultural machinery, such well-known brands as: Komatsu, Cummins, Caterpillar, Hitachi, Isuzu, Hyundai, JSB, Volvo, Doosan, Liebherr, Fortschritt, etc.

General information and features of the model

Medium-weight hydraulic power equipment is in high demand at modern construction, quarry, mining and transport facilities to solve a wide range of tasks related to earthmoving, road construction and loading operations. And the Hitachi ZX 330 crawler excavator is deservedly considered one of the most popular models on the domestic market.

Rice. 1 - 31-ton Hitachi ZX 330 crawler excavator is rightfully considered a reliable and unpretentious workhorse

In preparation for the full-scale launch of the ZX series in the mid-90s, the design department of the Japanese corporation Hitachi Construction Machinery, in active cooperation with the world famous American company for the production of special equipment John Deere, developed and launched into production a crawler hydraulic excavator with an operating weight of 31 tons – based on the lighter and simpler Hitachi ZX 220 model. The new product was distinguished by an unprecedentedly powerful engine for its class (275 horsepower), a reinforced front boom design, and significant simplifications in operation and overall ergonomics. The power unit has successfully survived a number of re-releases up to and including the 5th generation, acquiring modern electronics and exhaust cleaning technologies to meet increasingly complex environmental standards.

Despite the considerable age of the series and the obsolescence of individual components and systems - which is not surprising, since representatives of the first generation ZX began rolling off factory lines more than 30 years ago, such equipment is still distinguished by impressive reliability, unpretentiousness to conditions and performance, being able to effectively work (after appropriate modernization and periodic restoration work) for more than one decade, even in the harsh domestic realities. Of course, individual components wear out over time and become unusable, requiring repair, updating and replacement.

The process is irreversible and noticeably accelerates under intensive operating conditions and a frivolous attitude towards timely and high-quality maintenance. That is why it is so important to regularly monitor the condition of parts and undergo professional hardware diagnostics - and TekhStroyKomplektatsiya LLC will help extend the operational life of our clients’ tracked technology park, allowing them to profitably buy spare parts for the Hitachi ZX 330 excavator, as well as offering highly qualified and affordable services for repairing special equipment.

Hitachi ZX 330 excavator engine

The source of driving and working power for this model is the 6-cylinder in-line diesel engine Isuzu AH-6HK1. Developing a power of 202 kW at a nominal crankshaft speed of 1900 rpm, the engine is capable of producing 275 horsepower and consuming from 23 to 38 liters of fuel per hour, depending on the operating mode used. The basic package includes adaptive adjustment of direct-flow fuel injection using electronic control of Common Rail injectors, a turbocharger with a built-in intercooler for rational use of exhaust gas energy and a liquid cooling system. A special feature of the Hitachi ZX 330 model is the parallel arrangement of cooling elements, which has a positive effect on the simplicity and speed of service, and a special mode of minimum fuel consumption ECO (reducing consumption by 10%). For stable operation of the internal combustion engine and reliable prevention of possible breakdowns, it is extremely important to use only process fluids, lubricants and fuel that comply with the technical data sheet of the power unit.

Rice. 2 — Engine of the Hitachi ZX 330 excavator, model Isuzu AH-6HK1

The significant experience of motorists at TekhStroyKomplektatsiya LLC, accumulated over many years of repairing Isuzu AH-6HK1 engines, allows us to identify the main malfunctions of the internal combustion engine of the Hitachi ZX 330 excavator. One of the most problematic issues during engine operation is the violation of the fuel gas distribution mechanism. The reason is the injector valves going beyond the normal temperature range, and the cure is repeated hardware adjustment. The valve protecting the air hose of the high-pressure fuel pump can also become weak. The result is mechanical damage, cracking and possible rupture of the conductive line. A comprehensive engine repair is required, during which the owner will need to buy a fuel injection pump for a Hitachi ZX 330 excavator - and our company will help you make the most profitable order of parts for the engine of special equipment with prompt delivery and without overpayments.

Hitachi ZX 330 excavator chassis

The Hitachi ZX 330 hydraulic excavator can be called a self-propelled power plant very conditionally - the unit’s own maximum speed ranges from 3.6 to 5.5 km/h, depending on the operating mode used. Nevertheless, the elements of the chassis of Japanese excavators of this modification are characterized by extremely high strength, reliability and wear resistance, and the angle of inclination overcome by the equipment exceeds 40 degrees.

The X-shaped supporting frame is made of monolithic steel profiled beams, welded together with solid seams and fastened with threaded bolts. The frame of the excavator chassis is reinforced with thickening of the metal profile by 50 mm at the most critical points and spacers to control the rigidity of the structure. The side steps are additionally equipped with special support plates made of high-strength rubber for increased durability.

Rice. 3 — Tracked undercarriage of the Hitachi ZX 330 excavator close up

The expanded dimensions of this model required Japanese engineers to increase most of the elements of the Hitachi ZX 330 chassis, in particular the support and guide rollers and the upper brackets. The ground clearance is thus 500 mm, and the shoe has grown in width to 600 mm. In the basic kit with the new equipment, three types of protective coating are supplied (flat, regular and reinforced with triple grouser), each of which in its own way effectively copes with the threat of links disengaging while moving over very rough and rocky terrain and performing turning maneuvers.

The rich experience of the specialists of TekhStroyKomplektatsiya LLC in the professional repair of special equipment allows us to confidently identify the most problematic situations in connection with which there may be a need to urgently buy spare parts for the Hitachi ZX 330 excavator. Most of the problems with the structural elements of the tracks (support and guide rollers, idlers, sprockets , shoes, links, fingers, intermediate pins, bushings, gears and bearings) is associated with improper tension of the track and chains and general negligence in operation - failure to follow such simple rules as ensuring that the direction of the boom corresponds to the location of the tension wheel during the excavation process, irregular cleaning tracks, frequent and prolonged use of reverse mode.

The ones that begin to fail most quickly and certainly need to be replaced are the sloths (they are also the wheels that set the direction on a crawler excavator) - it is worth considering that the rate of their wear very much depends on the condition of the rubber seals. In the process of intensive work, the track sprockets are also at risk - their teeth can intensively wear out, crack and break off. The destruction of belt links is concentrated in three main areas: between the shoe and the upper edge of the link (at the point of contact with the roller) and on the bearing bushings (both internal and external).

In case of such malfunctions, owners prefer to re-purchase spare parts for the Hitachi ZX 330 excavator chassis and completely replace the faulty parts - their cost and internal structure do not imply the feasibility of carrying out any restoration work. In more complex cases, when the breakdowns become complex, components of the supporting frame, tensioning mechanism or transmission are damaged, professional repair of the running gear of the Hitachi ZX 330 excavator is necessary - and the employees of TekhStroyKomplektatsiya LLC have been performing a wide range of highly qualified services for the restoration of faulty special equipment of any kind for many years. degree of difficulty.

Hitachi ZX 330 excavator hydraulics

The power generated by the Isuzu AH-6HK1 engine is effectively complemented by the integrated HIOS hydraulic system. It includes 3 axial piston hydraulic motors with adaptive adjustment of the applied power (2 travel and 1 rotary), 2 corresponding pumps with an oil flow rate of 288 l/min each and a separate control gear mechanism. Special dampers and safety valves.

Rice. 4 — One of the main hydraulic pumps of the Hitachi ZX 330 excavator, removed for diagnostics by specialists from TekhStroyKomplektatsiya LLC

The vast majority of hydraulic problems directly result (in every sense of the word) from failure to promptly replace suction and full flow filters and replenish hydraulic oil supplies, as well as the use of unsuitable or low-quality process fluids. Craftsmen who repair the Hitachi ZX 330 excavator at the bases of TekhStroyKomplektatsiya LLC regularly have to solve problems of oil leaks and foaming, pressure drops inside the circuit (pump and seal wear, mechanical damage to conductive hoses, clogged filters, dampers and valves, increased oil viscosity), extraneous noise and uneven operation of hydraulic units (severe wear or malfunction of hydraulic cylinders, speed controller, spools, chokes, etc.). There is no problem that cannot be solved by professional repair work - and our company will help you buy spare parts for the Hitachi ZX 330 excavator profitably and with a quality guarantee and return the equipment to operation in the shortest possible time.

Hitachi ZX 330 excavator cab, turntable and attachments

Like the rest of the excavator skeleton, the top platform and turntable of the Hitachi ZX 330 excavator were designed with a significant margin of safety in mind. This is evidenced by the extremely strong and rigid rotating frame, made of welded profiled beams with a D-shaped section. The deployment of the platform (the minimum radius is 3370 mm) is carried out through the operation of an axial piston motor combined with a planetary-type rotary gearbox and a disc brake with hydraulic release.

Rice. 5 — Removed cabin of the Hitachi ZX 330 excavator

The signature unibody CRES cab is considered one of the best examples of safety and convenience in the industry, strictly meeting the upper limit conditions of Category 1 of the international safety standard ISO 10262. Reinforced flat glass windows, tinted green, on all four sides (plus the fifth in the roof of the optionally available cab version K) provide optimal visibility, even without taking into account the optional built-in rear view camera and hinged protection. Inside, the most comfortable and freely customizable atmosphere is created for the operator - an adjustable seat with armrests and several stationary backrest positions, advanced air conditioning and ventilation systems, convenient control joysticks, lighting for night work, a retractable seat belt, and a radio receiver.

Starting with the third generation of the Hitachi ZAXIS 330-3 excavator, the on-board interface in the cab has expanded and began to include color liquid crystal displays for connection to multifunctional software - active monitoring of equipment condition and the level of process fluids, selection and correction of operating modes. Among the settings there is even the ability to choose from 12 languages and a built-in code immobilizer to counter attempts to steal special equipment.

The forward and reverse booms have been significantly strengthened compared to the model’s predecessor, the Hitachi ZX 220 excavator, and allow the equipment to be quickly converted to meet current needs with replaceable sets of hydraulic tools. This includes a wide range of buckets of various shapes, sizes and purposes - for digging pits and trenches in almost any type of soil. No less in demand are specialized devices with hydraulic reinforcement - a hydraulic hammer and hydraulic shears with an optional rotator, which are optimally suited for breaking up asphalt during road work and dismantling concrete and reinforced concrete structures. Both drilling augers and single-tooth rippers are actively used at mining and quarry sites. On the website of TekhStroyKomplektatsiya LLC you can view and buy attachments for the Hitachi ZX 330 at an attractive direct price or order professional repair of an excavator turntable that has ceased to adequately perform its functions.

Modifications of the Hitachi ZX 330 excavator

The increased loads to which the Hitachi ZX 330 hydraulic excavator can be subjected, thanks to its powerful Isuzu AH-6HK1 engine and rugged design, has led to the need for a more extended tracked chassis to avoid tipping attempts when lifting a full bucket. Therefore, the Hitachi ZX 330LC modification (Long Crawler - extended tracks) has become no less popular than the basic product of the Japanese corporation.

Rice. 6 — Modification of the Hitachi ZX 330 excavator with an extended tracked base

The length of the modified version's chassis is 4940 mm, versus 4640 mm for the standard version, which adds additional stability to the equipment, but has a negative impact on the weight, reaching up to 33 tons with certain attachments. Most of the spare parts for the extended modification of the excavator are fully compatible with conventional ones, and the owner of such special equipment will not have any difficulty in purchasing spare parts for the Hitachi ZX 330LC by selecting the necessary parts for the special equipment on the TekhStroyKomplektatsiya LLC website.

Description and features

The excavator is equipped with a six-cylinder diesel power unit brand AH-6HK1XYSA-01, which is an in-house development of partner manufacturer Isuzu. This engine has a displacement of all cylinders of 7790 cubic meters and a modern common rail fuel supply system. The unit fully complies with modern environmental standards. It is worth noting that the noise level of this unit is quite low, which additionally affects the operator’s work comfort. The installation was supplemented with a turbocharging system, which made it possible to achieve increased power indicators.

The chassis of the equipment is a powerful X-shaped box-section frame, which is made of high-strength steel. The use of this design has significantly increased the overall strength and service life of the excavator, since it is most resistant to bending. Also, thanks to the use of an X-shaped frame, the machine has increased maneuverability and stability when moving on uneven surfaces, which allows the machine to be operated in places that are quite difficult to reach for any other special equipment. The excavator tracks also have their own frame, which is welded using high-quality materials to the side frame.

The turntable frame is also made of high-strength steel using the latest welding technologies and further processing of welds. The frame is made in the form of a D-shaped box-shaped structure and has high resistance to deformation under shock loads and shocks. The main reinforcement of the structure is thick-walled steel plates. The entire superstructure is rotated by means of hydraulic drives, a special rotating mechanism, an axial piston hydraulic motor and a planetary gearbox, which was located in an oil bath to ensure increased efficiency and durability.

This model used its own control system, which included several different operating modes. Some modes make it possible to achieve a 10 percent reduction in diesel fuel consumption, which has a positive effect on costs during active operation.

During the development of this excavator, great emphasis was placed on working conditions and operator safety, which is currently one of the key advantages of all Hitachi brand products. The sealed cabin is equipped with a wide LCD monitor, which can display a rear view, thanks to the standard rear view camera. This provides not only increased visibility, but also an increased level of safety for both the operator and others. The camera itself is located on the counterweight of the machine. Its operation is carried out automatically when moving independently, and when the equipment stops and begins to perform any operations, the camera turns off and all the necessary indicators and parameters of the current state of the excavator are displayed on the monitor (cooling system fluid temperature, hydraulic fluid temperature, pressure in the hydraulic circuits, pressure in the power plant, the fuel level in the tank, as well as the level of all working fluids). If it is not needed, the operator can independently disable the rear view camera using the functions of this monitor.

The front window of the cabin is thick, made of safety laminated glass. The design of the cabin is thought out to the smallest detail. The large glass area provides the operator with excellent all-round visibility of the work area, which has a positive effect on both the accuracy of the operations performed and overall safety. It is worth noting that the manufacturer installed a special device that tilts the entire cabin forward and backward by 30 degrees, which increased the operator’s visibility. The front window has dual wipers for increased visibility in harsh operating conditions. The cabin roof has a glass hatch that is resistant to various impacts. This sunroof has one wiper and washer.

In order to ensure increased cabin comfort, the manufacturer has applied a lot of solutions. An air conditioner and a powerful heating system are standardly installed, which allow you to maintain the necessary microclimate, regardless of environmental conditions. To reduce the level of extraneous noise and vibrations arising during the work process, high-quality sound-proofing and vibration-absorbing materials were used, including door seals.

The controls of the equipment are made in the form of joysticks and have a fairly short stroke, which significantly increases convenience when performing various tasks. The cab has a large free space at the operator's feet and a comfortable seat. The seat installed as standard is equipped with several adjustments, which allows the operator to choose the most comfortable position, taking into account his body size. The seat back has inertial seat belts. There are also wide armrests that can be adjusted if necessary. The more expensive equipment of the machine includes a seat mounted on an air suspension, which allows you to significantly smooth out the shaking and shocks that occur during any operations and almost completely eliminate vibrations during operation. Additional switches are optionally installed on the work equipment control joysticks, which are designed to manipulate mounted units that have an additional hydraulic drive, namely jackhammers, shears, grippers, drilling units, vibratory rammers, clamshell buckets and many others.

The manufacturer offers several types of arrows and handles, differing in strength and length. Such equipment of an excavator is often necessary when performing various dismantling works, since elongated working parts can significantly increase the level of reach.

In general, over quite a long period of operation, the equipment stood out among its class due to its endurance, productivity and unpretentiousness both to operating conditions and to the quality of diesel fuel consumed. Maintenance of this excavator is distinguished by its convenience and simplicity, which is due to long service intervals and full access to all the most important elements. Moreover, all spare parts are now very widespread and affordable. Thanks to all these qualities, the Hitachi ZX350 crawler excavator has gained quite a lot of popularity in Russia and many CIS countries.
