The professional standard for the instrument fitter in the chemical industry. Job description for a plumber. What can you do on wheels

The production of tracked and wheeled excavators is a rather costly, profitable and promising business. They are usually engaged in by large engineering corporations with a long tradition of engineering.

Two such corporations - the Italian Fiat and the Japanese Hitachi, which is one of the largest in the world, in 1986 created a joint venture for the manufacture of excavators FIAT-HITACHI EXCAVATORS S.P.A. 60 percent of his capital was owned by an Italian corporation, 40 percent by a Japanese corporation. The plant was located in the suburbs of Turin - the town of San Mauro in northwestern Italy. The production of high-quality special equipment was organized here - wheeled and tracked excavators, as well as backhoe loaders.

Their designs took into account the extensive experience in the creation of earthmoving machines. In 1993, the production received the ISO 9001 certificate, which confirmed the high level of production organization and product quality. In addition to Italy and Japan, the company's factories operated in Brazil, Germany and the United States. Its successful models are still successfully operating in many countries today. However, excavators were produced under this brand until 2001, when the joint venture was liquidated. The owners of cars of this brand did not feel the changes. They can still be served in a service network that is extensive across all continents. There are no problems with spare parts.

Tracked vehicles

Crawler excavators have the advantage of a larger bucket capacity, excavation of soil from different depths with a significant boom reach.

Fiat-Hitachi EX 455 Operation: Operating weight 46000 kg; Fuel volume 605 l.; The volume of liquid of the cooling system is 43 l.; Engine oil volume 50 l.; Operating voltage 24 V. Generator current 40 amps Hydraulic bypass valve pressure 30,000 kPa Hydraulic pump capacity 720 l/min

Some of the most efficient crawler excavators are the 47-ton Fiat-Hitachi EX 455 and the 35-ton EX 355.

Operation Fiat Hitachi EX355: Operating weight 34000 kg; Fuel volume 560 l.; The volume of liquid of the cooling system is 39 l.; The volume of fluid in the hydraulic system is 320 l. Engine oil volume 35 l. Operating voltage 24 V Generator current 40 amps Hydraulic bypass valve pressure 32000 kPa Hydraulic pump capacity 520 l/min

Their buckets have a capacity of almost two cubic meters. These powerful machines are capable of handling the toughest excavation jobs.

Fiat-Hitachi EX 225 and EX 255 have a mass of over 26 tons, engines with a capacity of 177 hp. and almost one and a half cube buckets. Their tracks, 60 cm wide, provide high flotation and minimal ground pressure.

FIAT-HITACHI EX255/LC/EL

The Fiat-Hitachi EX 215, which weighs over 21 tons, is not much inferior to them. However, thanks to the tracks of 80 cm wide, its pressure on the ground is minimal. The EX 165 has unique qualities. Its turntable can make 13.2 revolutions per minute, which allows for high productivity. Together with the ability to dig almost 8 meters long and up to five meters deep, this machine can be indispensable in many situations.

What can you do on wheels

Wheeled excavators are distinguished by good maneuverability, the ability to move relatively quickly on roads without creating problems for other road users. This allows you to quickly transfer them to different objects to work with the most difficult soils. Due to their excellent performance characteristics, they are always in demand.

The 21-ton Fiat-Hitachi EX 215W wheeled machine, can dig far and deep, and quickly move to a new job site, has a quick change device.

Fiat-Hitachi EX 215W

The smaller 14-ton EX 135 with an engine power of 103 hp. has compact dimensions and is able to perform work where powerful tracked vehicles cannot get close. Good technical characteristics of the FH 200W with a 125 hp engine. It has a weight of 19.2 tons, a bucket with a volume of 1.5 m3 and a hydraulic line for attachments.

Lightweight and functional

Wheeled excavators-loaders differ in wide functionality. They can dig holes and trenches, load and unload bulk cargo, serve emergency crews for the repair of communications, clean up the territory and plan construction sites, and perform other work. This is facilitated by attachments, which can be quickly installed on such machines. They can move quickly on common roads, have enviable cross-country ability. Their equipment is basically the same. Bucket at the front, backhoe excavator at the back and mandatory supports.

They differ in their capabilities depending on the model. So, the front bucket can perform the functions of a dump or reloading of various cargoes. It can also be of a jaw design, which allows you to do the work of a scraper, grab loads and lift them. Digging capabilities are determined by the design of the boom. Excavators loaders in addition to excavating the soil can unload it to a certain height.

Backhoe loaders are among the light and mobile excavators. So Fiat-Hitachi FB 100 with a 97 hp engine. can perform any work, while spending 4 liters of fuel per hour.

Backhoe loader Fiat-Hitachi FB 100.2

One of the most common was the FB 110 weighing 7.7 tons. With a power plant power of 112 hp, it can dig to a depth of 6.1 m with a bucket of 0.76 m3. Using a loading bucket with a capacity of 1.1 m3, it is able to unload soil at a height of 2.7 m. The compactness of this machine with dimensions of 5.7x2.4x3.9 m allows it not only to move freely on the roads, but also to work in confined spaces.

Backhoe loader Fiat-Hitachi FB 110

Fiat-Hitachi FB 200 and FB 200 4WS 9-ton backhoe loaders have unique characteristics. These two-bucket all-wheel drive machines are also able to move like a crab. With a rear bucket of 0.3 m3 on the telescopic boom, the FB200 can dig to a depth of 7 m. The front bucket of the FB 200 4WS is jaw-shaped. He is able to collect up to one and a half cubic meters of soil and pour it into the back of a large truck. An eight-ton Fiat-Hitachi FB 90 with its cubic bucket can dig almost five meters deep and six meters long.

About the smallest excavators

Small Fiat-Hitachi excavators are usually called mini-excavators for their compactness and relatively low weight, which does not exceed one and a half dozen tons. These are significantly different from other machines in terms of dimensions and weight of the fourteen-ton Fiat-Hitachi EX 135 and EX 100, which weighs 13.5 tons with a bucket of 0.3-.0.35 m3.

Fiat-Hitachi EX 135

Fiat-Hitachi FH 120 weighing 12.6 tons and more than half a cube bucket. Small machines include the ten-ton FH 90 W, as well as the FH 75 and FH 40, which weigh 8 and 4 tons, respectively. They have smaller bucket volumes and lower power engines. These are the smallest of the small-sized excavators of this brand. Good reviews about the work of Fiat-Hitachi FH 45.2 plus. Compact excavators have a light and very strong base frame, low center of gravity, high power density. Reliable automatic brakes of the turntable, self-lubricating system of hinges of working mechanisms.

What are they equipped with

Fiat-Hitachi excavators usually have American Cummins diesel engines, which are also equipped with armored vehicles and tractors. Power plants meet all modern requirements and are distinguished by:

advanced fuel injection system;
strong torque when the speed is not high;
turbocharging system;
automatic reduction in the number of revolutions when the load drops;
all-weather start and smooth operation.

Excavator hydraulic systems operate smoothly and quickly, delivering high productivity. Powerful, easy-to-operate hydraulic pumps play a decisive role here. They have durable hydraulic cylinders and a good hydraulic oil filtration system. In the event of an overload of the hydraulics, it can be automatically blocked.

All-wheel drive transmission of wheeled vehicles with reliable brakes ensures their stable movement. This, as well as reducing the pressure on the ground, is facilitated by dual wheels on both axles of excavators.

Both Fiat-Hitachi wheeled and tracked excavators are equipped with front and backhoe buckets, hydraulic hammers, rippers, grabs and other hydraulically driven attachments.

The machines have the necessary comfort for convenient and safe work of the operator. Their cabs have excellent all-round visibility. In the event of a rollover of the machine, there is a strong metal frame that can protect a person. Vibration is almost not felt at his workplace. There are ventilation and air conditioning systems. There is good noise and dust isolation. Very comfortable seating. Ergonomic controls. Dashboards are informative and have a pleasant backlight. Efficiently organized cab lighting and work areas.

Despite the cessation of production of Fiat-Hitachi excavators, many of them remain in demand. With their high performance and reliability, they confirm the validity of the design solutions adopted during their creation.
