Several years ago, a new model appeared on the world market of special equipment, presented by the large Japanese manufacturer Hitachi Construction Machinery. This machine is the Hitachi EX 400 crawler excavator. During the development process, the manufacturer mainly focused on the markets of the CIS countries, Russia and other developing countries. The equipment uses an advanced Isuzu power plant, the main advantage of which is proper operation even when using diesel fuel of rather low quality, which is precisely what is important when operating in Russian conditions. The excavator was first demonstrated in Russia at an exhibition in 2013. If we compare this model with previous machines, the Hitachi 400 is much more productive and efficient.

Description and features

At the premiere, Hitachi specialists emphasized that the new excavator received an improved layout of working units and assemblies, a reinforced chassis and an improved HIOS III hydraulic system, which, in addition to high load capacity and reliability, also reduces fuel consumption. The machine can easily boast of its high strength, since another goal of the manufacturer was to create equipment that can withstand rather difficult operating conditions. Moreover, the excavator is standardly equipped with a digging bucket with a capacity of 1600 cubic millimeters, as a result of which the equipment is able to cope with a large volume of work in the shortest possible time. In terms of safety and environmental friendliness, this crawler excavator fully complies with all modern standards.

This model used a modern engine control system, thanks to which it was possible to reduce specific fuel consumption during operation by 10 percent. This system is more of a special mode, since it comes into effect only after activation.

Each model of special equipment has its own unique features and advantages, and the Hitachi EX 400 is also endowed with them. Its key advantages are:

1. Long service life of all elements and high reliability. The excavator chassis and cabin design have undergone some improvements, resulting in additional reinforcements, which has a positive effect on both the reliability and safety of the equipment.
2. Maintenance is simple and not particularly costly in terms of financial investment. The design of the equipment is designed in such a way that maintenance personnel have full access to all the most important elements that require regular inspection. All spare parts are now widely distributed, which is why they have a very reasonable price.
3. Speed ​​of operation of the working parts of the excavator. The manufacturer has equipped the machine with two very useful operating modes that make the equipment more efficient and productive. The first mode is Auto Power Lift. Its essence is that when activated, the boom lifting force automatically increases by 10 percent depending on the degree of load. If the hydraulic system does not experience special loads, the force parameter returns to its original value. The second mode is Power Boost, which when activated increases arm force by 5 percent and bucket cutting force by 4 percent. Its difference from the first mode is its constant action, when the first one automatically turns on and off. The operator can disable Power Boost mode independently.

In Russia, the Hitachi EX 400 crawler excavator is quite popular and in demand among large construction organizations and industrial sectors. This is explained by the fact that in addition to being unpretentious, the equipment also has excellent performance characteristics.

This model is not without reason intended for operation in rather harsh conditions. The track platform has been significantly improved, and its protection has received additional reinforcements, thus significantly increasing wear resistance and traction force by 15 percent compared to previous models. It is worth noting that in almost all technical and operational indicators, the Hitachi 400 is superior to most machines in its class.

The equipment is equipped with a short-throw gear lever, which is very convenient to use. This made the operator's work more comfortable. At the same time, the boom pulling speed increased by 20 percent, which increased productivity.

Another important advantage of this crawler excavator is the increased level of operator safety. This parameter has been improved through the use of reinforced front glass, which can withstand serious impacts, and a special cabin with a FOPS protection system. Due to the new synchronization system, the noise level has decreased and the efficiency of the equipment has increased.

The excavator cabin was quite spacious and comfortable. It uses various sound-absorbing and vibration-insulating materials, due to which the level of extraneous noise and vibrations arising during the working process is extremely low. Compared to its predecessors, the cabin in this model was slightly enlarged. This is especially noticeable in the legroom, which is 55 percent larger. All controls, both for attachments and for the equipment itself, are located as ergonomically as possible, so that even an inexperienced operator will not have any problems during operation. There is also a comfortable seat with full adjustment and a reclining backrest. It is worth noting that the seat can be moved either together with the controls or separately from them, which allows you to choose the optimal position for the operator of any build. All of the above has a significant impact on reducing fatigue and increasing productivity and quality of work performed.

The Hitachi EX 400 crawler excavator has a very long service life and high maintainability. The manufacturer has increased the replacement intervals for various equipment elements. The oil of the power plant and hydraulic system is replaced every five thousand operating hours.

Purpose

This equipment is most in demand in large construction organizations, industrial sectors, quarries, mining operations, deposits, road repair and dismantling works. As described above, the excavator is equipped with a 1.6 cubic meter digging bucket, with which it is able to perform most of the entire list of work being done, namely the creation of embankments of soil and other bulk materials; moving any cargo over short distances; digging trenches and pits of any depth and size; filling holes and trenches; loading and unloading; destruction of small buildings; leveling the working area.

With additional attachments, the excavator performs the following work: loosening solid soil masses and rocks; compaction of loose soil; opening the asphalt layer of road sections; destruction of concrete and reinforced concrete structures; driving and extracting piles; drilling of various wells; cleaning the area from industrial waste.
