Semi-trailer truck Isuzu GIGA ЕХZ52KH

Heavy series trucks GIGA Isuzu Japanese brand is an interesting choice for the construction transport of heavy and bulky loads and operate in harsh conditions. Trucks big tonnage produced in Japan is structurally very different from their European counterparts.

The point is to approach. Practical Asians prefer to work rather austere, but a solid technique, and specificity of long-range transport they are fundamentally different. Against this background, it is interesting to consider semi-trailer truck Isuzu GIGA 6×4. On the one hand, heredity is the design of the school and the slow pace of modernization, on the other scale – atypical own decisions, for example, the architecture of the fuel system to ensure that the fifth environmental class without the use of unpopular in our country, “urea” neutralization and hyperclones particulate filter.There is a lot of interesting things, and most importantly, durable in construction, not typical of today’s trend…

Workplace typical for Japanese truck, the instrument cluster is quite informative.

Purpose

Heavy series GIGA are produced in Japan and then all vehicles undergo the necessary adaptation for the Russian market. The range of products for Russia machines wheel formula 4×2 and 6×4 GVW from 33 to 60 tons.Most of the trucks find their customers in the form of a chassis, and only after installation of the add-ins starts their operation, but today we have the finished truck, and even with a margin of safety for transportation of various loads: regulated total train weight with this locomotive – 48 of 630 kg, technically permissible nearly a quarter more of 60 tons. Servicing the construction industry, municipal economy, industrial enterprises, working in a relatively small shoulders, but with high loads – that element of our tractor;normal couple: a semi-truck or a truck, or just side with a cargo of bricks, concrete blocks, pipes. From the standpoint of this script operation should be seen this tractor.

What will the owner of the cabin

As stated in the advertising slogan Isuzu, the manufacturer considers it his duty to the client to build the most durable trucks that can operate in the toughest conditions. New cabin design performs a very practical function. Large “nostrils” of the front grille, under the plan of the designers, provide a flow of additional air volume and increase the efficiency of the intermediate cooling air, thereby improving fuel efficiency. It’s outside, but will start with the introduction of the workplace.

If the driver is not spoiled very new and well-equipped trucks big seven from Europe, will be openly happy and not without reason. Hands most of the working time will now be clean, rusty and rough crooked tool in the box on the frame you can now give the younger comrades, the cabin is warm and cozy, and even has a bed with a mattress factory of origin. Quite different to your new workspace will take a look yesterday’s international peresevshih the ” – ” or “Scania”.”What kind of a low ceiling, where doubles of the keys of the cabin lighting and auxiliary heater on the back wall, why is it so closely and rigidly that the “trunk” lever CP, th, and next to another one, but lying, – “the hammer” is called! Is that a tractor or industrial “tram”? We have seen “eurobudget”, and do not need to generalize…

However, many people, so many opinions. A compromise can always be found. Albeit there are no bedrooms, but there is a shelf; no individual unit on the back wall, but there is a huge lampshade on the ceiling, no LCD displays, but the “microcirculatory” figures on the trip computer so I know a lot of the current options, no touch climate control, but the antediluvian engines-controls heating and ventilation are simple and clear, and the air regularly carry the service. In the centre of the cabin, an extra seat easy transformirovalsya in the table.In the basic configuration air conditioning, stereo system, power steering, adjustable steering column, ABS, headlight range control, electric Windows, heated mirrors. So, whether we like it or not, accept our “gig” for what it is, and begin to learn her muscles.

The fullness of the family

In the family in addition to heavy-duty trucks Isuzu presented chassis wheel formula 6×4 with four wheelbase options. The engine is the same as 15.7 l/400 HP, but KP seven-speed. The chassis load capacity – 24 tons In Russia there is a network of authorized manufacturers of add-ins that are ready to offer approved by the vehicle manufacturer decisions. Because the chassis is equipped with a manual PTO, you can use it as ABS, or like a dump truck, or any other add-ins that require mechanization. In a series GIGA there is also a tractor with the wheel formula 4×2, able to train full weight up to 45 t

Chassis technology

Technically permissible loading capacity chassis, in our case, consider the load on the saddle – 17,4 ton, GVW three-axle tractor – 26 T. Like most “Asians”, ЕХZ Isuzu leaf spring suspension on front and rear axles, terribly hard, for the sake of the stated capacity. As befits a construction tractor, wheel brakes-drum.

Channel ladder-type frame made of high strength steel, the distance between the frame rails 850 mm. the dimensions of the longeron 285×85 mm, thickness of 7 mm. Front axle – I-beam without forks at the ends, load capacity – 7500 kg. the Front suspension done this on semi-elliptic leaf springs, alloy steel. Rear – semi-elliptical leaf springs made of alloy steel with the shaft of the pivot axle. Unfortunately, the anti-roll bar front is available only as an option, and the rear is not provided.

Rear axles with one-piece housings with full floating axles, hypoid gearing and a center differential with locking device load capacity – 21 000 kg (25 000 kg for vehicles with RHD), middle bridge entrance. Steering gear screw – ball nut with power steering the gear ratio of the steering mechanism – 20,2.

The layout of the rear brake chambers looks vulnerable, but still no complaints from operators were reported

Contrary to the EU, but the exhaust is strictly normal

Obeying the push of a button, triggered an electric cab lift, opening for viewing the Isuzu engine 6WG1E5RC the fifth environmental class. Almost 16 liters displacement inline “six” given the relatively modest 400 horsepower and 1863 Nm of torque. The trucks “seven” such indicators routinely shoot 12 or 13-litre engines, and sometimes even ten-litre on holidays. Momentum maximum power of low – 1800 rpm In this motor there is no AdBlue injection or multi-stage particulate filter.The environmental requirements of Euro 5, the creators of the machine is provided, parentrow system exhaust gas recirculation (EGR) and introducing additional catalyst, DOC (Diesel Oxidation Catalyst) in the exhaust system. Fuel system – Common Rail, variable geometry turbocharger (VGS), which are gradually giving in countries where the popular Gothic style, and gabled roofs of buildings. In short, everything as ordered, is clearly contrary to the last generation of European trucks. But the low liter capacity is a kind of guarantee of longevity.

The power supply system is protected by two filter separator heated. Further, the fuel through one filter gets to the two-piece fuel pump that supplies fuel at rail pressure of 160 MPa, and performance even of one section will suffice, in the event of a malfunction continue driving. Fuel rail installed damper flow rate, which not only smoothes the pulsation of the fuel, but also covers feeding in the event of a leak in the high pressure line.
