Device Features

The excavator is equipped with:

• reliable suspension and tracked base, durable rotating platform, demonstrating long service life under heavy loads and off-road conditions;
• spacious, sealed, durable cab with shock-absorbing supports and other structures for operator comfort and safety;
• steel welded handle and welded box-section boom.

The Hitachi EX400 crawler excavator is equipped with a 1.6 m³ bucket. The bucket is made of high-strength steel, resistant to damage and corrosion.

Hitachi 400 has a number of advantages and has high performance and technical characteristics.

Powerful, reliable, environmentally friendly engine

An important advantage of the internal combustion engine of Hitachi special equipment is its provision of high power density combined with fuel efficiency.

Special equipment of the Japanese manufacturer is traditionally equipped with an Isuzu brand power unit. The modern 4-stroke diesel engine Hitachi 400 is equipped with a turbocharger with an intercooler and an improved speed controller. A highly efficient multi-stage cooling system ensures uninterrupted operation of the internal combustion engine during shifts of any duration.

The rated power of the Isuzu engine installed on the four hundredth model is 202 kilowatts or 275 horsepower.

In terms of exhaust gas toxicity, the Hitachi engine complies with international environmental standards Stage II (EC) and EPA Tier 2 (USA)

Performance and toughness

The Hitachi EX400 received a reinforced chassis, strengthening of other components and structural elements, and improved assembly of units to increase reliability. The machine is ready to work in Russian weather and road conditions, can be operated in frosty and hot weather, and will operate even on low-quality diesel fuel.

High performance is ensured by many small design improvements. For example, thanks to an improved mechanism, the speed of boom extension is increased by 20% compared to the same parameter for Hitachi special equipment produced before 2010.

Reduced fuel consumption with high efficiency

The latest generation of excavators from Hitachi are equipped with an advanced HIOS III hydraulic system. It provides high lifting capacity and productivity with lower fuel consumption. The improved HIOS III hydraulic system also helps reduce CO₂ emissions into the atmosphere.

The latest models of Hitachi special equipment have modes available to increase productivity and reduce diesel consumption. Starting the Auto Power Lift mode increases the boom lifting force by 10% and, accordingly, speeds up the lifting of the working element. The option can be used, for example, when laying communications in the ground. When there is no load, the force level automatically returns to its original value; turning off the mode is not required.

The Power Boost mode is turned on for a short-term increase in performance and bucket by 5% and 4%, respectively. The operator can launch and disable the option independently. The additional ECO mode reduces diesel consumption by another 14% without affecting the efficiency of other components.

Simple maintenance and repairs

The design features of the Hitachi EX400 allow you to carry out scheduled maintenance at any time and promptly replace consumables and components. Maintenance personnel have access to all components that require regular inspection. Ease of maintenance and repair, widespread availability and low cost of spare parts make the model economical to operate.

When repairing Hitachi 400, it is important to use original components. Original oils and filters better protect hydraulic elements from wear. Hoses from the manufacturer are able to withstand the maximum pressure encountered in the Hitachi hydraulic system. Original chassis elements allow the equipment to operate in harsh conditions of Russian off-road conditions, construction and demolition of objects.

Operator comfort and ease of control

One of the key advantages of the model is an enlarged, spacious and comfortable operator’s cabin, which helps reduce fatigue and increase the efficiency of personnel operating special equipment.

The cabin is quiet: it is finished with sound-absorbing and vibration-insulating materials. Panoramic visibility eliminates blind spots. This reduces the risk of accidents and injuries during work.

The specialist operates the machine from a comfortable reclining chair with 55% more legroom (compared to older Hitachi excavator models). The position of all elements of the chair can be adjusted. It is possible to simultaneously move the seat and adjust the location of the working devices, which allows a person of any size to comfortably fit in the cab and operate the machine.

Conveniently located controls and a multi-function display help you adapt to the machine and carry out work tasks with ease.

Driver safety

The Hitachi 400 model is equipped with standard operator protection systems when the machine turns over or rolls over. In addition, the equipment cabin is equipped with a reinforced windshield. If Hitachi glass is damaged, it does not form sharp fragments, which protects the machine operator from injury.

Possibility of retrofitting

The excavator can be equipped with various attachments to perform certain types of work.

The design of the machine allows the use of:

• vibrating rammers for compacting soil, creating bedding, gravel or sand cushion;
• vibrator for installing pipes and other structures in the ground;
• hydraulic rotator or hydraulic hammer for drilling and working with piles.

Disadvantages and advantages

New and used equipment from the Japanese brand is more expensive than many Russian and Chinese analogues. The price tag for original Hitachi special equipment can be attributed to the conditional disadvantages of the machine.

The high cost of the excavator pays off due to long-term and trouble-free operation of the equipment. Many Hitachi machines produced in the 90s of the last century are still running and are capable of efficiently performing work tasks. Modern models of the manufacturer are distinguished by greater comfort, improved performance, efficiency, safety and an equally long service life.

Another important advantage of the model is maintainability and the prevalence of original components, the use of which helps to extend the life of the equipment.
