Komatsu has released an updated model of its wheeled front loader Komatsu WA470-8, which reduces fuel consumption and improved the cab design. The updated loader is equipped with an engine that satisfies the modern environmental standard, Komatsu SAA6D125E-7. The Komatsu WA470-8 front loader consumes 6% less fuel than its predecessor.

Engine and control systems

The loader is equipped with the SmartLoader Logic system, which is activated on the second, third and fourth gears in combination with the torque converter blocking system. The system provides optimal torque of the engine, which improves acceleration, lifting the inclined surface with a higher maximum speed and fuel savings.

Rob Mac-Magon, Product Manager Komatsu America:

Komatsu WA470-8 combines stability, power and desire. Loader is suitable for work in any conditions. Available different attachments, which expands the versatility of the machine.

The Komatsu WA470-8 engine is equipped with a diesel particulate filter (KDPF), a catalyst for selective recovery (SCR) and other additional components to reduce exhaust emissions and an increase in engine life. The engine uses a modern electronic control system to control the speed of the air flow, fuel injection, combustion parameters, performance optimization, reduction of emissions, and provides advanced diagnostic capabilities.

The new Komatsu loader is equipped with an automatic idling system, which is turned on after a while after operator inactivity, to reduce downtime and save fuel.

The turbocharger with the variable geometry and recycling of exhaust gases (EGR) makes it possible to accurately monitor the temperature and air flow control.

Workplace operator

The operator's seat is equipped with a pneumatic suspension and a high heated back, which compensates for vibrations to improve the comfort of the operator. Next to the seat are arranged control levers for the convenience of the operator and reduce fatigue.

The onboard telematics and monitoring system provides the display of the necessary information about the status of the loader instruments, including the KDPF state, fuel consumption data, as well as on the work on the loader using the operator identification number.

The dashboard is equipped with auxiliary connector and two 12 volt ports. Cabin is equipped with 7? Full-color monitors with high resolution of the rear and forefront.

Komatsu WA470-6 is an all-wheel drive front loader with a 4 × 4 wheelchair, the distinctive features of which are: reliable and strong design, productive engine, good technical and operational performance and high security ...

It is adapted for use even in adverse weather and road conditions, and is intended to carry out loading and unloading, construction and installation, earthmoving and other types of work in various industries and national economy ... Komatsu VA470-6 by default Komatsu WA470-6 equipped with a cab with Panoramic glazing and inner decoration, characterized by an derived ergonomics and a comfortable driver's seat, which contains a chair with a comfortable profile, armrests, a pneumatic suspension and a large set of adjustments. In the Komatsu Wa470-6 cabin.

In length, the front loader reaches 8825-9210 mm, in width - 3170-3190 mm (taking into account the bucket), and a height is 3500 mm (in terms of the cab). Between the front and rear bridges, the machine "distributes" the 3450-millimeter base, and under the bottom she has a 525-millimeter clearance. The minimum rotation radius in the center of the outer wheel at the Japanese is 6630 mm, and the rut value is placed in 2300 mm. Dimensions Komatsu WA470-6 The operational mass of this technology varies from 22880 to 23110 kg depending on the execution. On Komatsu WA470-6 several types of buckets are installed: general purpose for fuses or ground removal; For rocks with a V-shaped edge; for bulk materials; For lightweight materials. The equipment mass is from 1970 to 2200 kg, and geometrical capacity - from 3.1 to 4.5 cubic meters (with a "cap" - from 3.6 to 5.2 cubic meters).

The maximum permissible height of unloading at the Japanese is 2975-3235 mm, and the depth of the cutting of the soil is 305-370 mm. The buckets for Komatsu WA470-6 for Komatsu WA470-6 are offered a six-cylinder 11.04-liter diesel for Komatsu Saa6D125E-5 with turbocharging, sequential cooling, direct fuel injection, recycling of exhaust gases and a forced lubrication system with a gear pump generating 273 horsepower (204 kW) at 2000 by / minute and 1360 N · m of torque at 1400 rpm. It is joined with a fully automatic gearbox (it has four front and four reversing steps) and all-wheel drive transmission with a symmetric distribution of thrust along axes and blocked differentials.

On standard tires dimension 23.5-25 The machine when moving forward can develop the speed of 7-33.7 km / h, and back - 7.3-34.7 km / h, and on the tires with a standard size 26.5-25, these indicators are equal to 7.6-36.2 km / h and 7.9- 37.3 km / h, respectively. The KOMATSU WA470-6 is a hinged frame, made of high-strength steel grades, on which all major components and aggregates are located, including a cabin installed on rubber supports. In front of the loader is equipped with a rigidly fixed bridge, and behind - balancing design (in both cases - with semi-breeded semi-axes).

The machine is equipped with a steering system with a hydraulic cylinder, oil cooled disk brakes with hydraulic inclusion, acting on four wheels, and a 413-liter fuel tank. In Russia, Komatsu WA470-6 in 2018 sold at a price of ~ 10 million rubles. The basic bundle of "Japanese" includes: a beep of the reverse, counterweight, an electronic engine stop system, a wiper and a rear window glass player, an operator chair with a pneumatic suspension, sunscreen visor and other equipment.

Komatsu has launched an updated WA470 wheel loader model, which boasts a reduced fuel consumption and an improved cab. He heads all the improvements to the new Komatsu SAA6D125E-7 engine-7 standard Tier 4 Final.

Features of the novelty

The selective catalyst (SCR), as well as the exhaust diesel fluid (DEF) reduce the emission level, while the automatic shutdown system, with a simple and electronic control system, determine the air flow and fuel injection. Due to this, it was possible to reduce fuel consumption by 6%. Also, the modified turbocharger geometry and exhaust recycling systems provide more accurate temperature control and air flow.

Inside the cabin, the operator will detect a couple of interesting changes. Perhaps the most useful will be a chair with a high back, heated and a new pneumatic suspension. Representatives of Komatsu say that they have made serious work to reduce vibration, which affects the driver. Also, the control panel and joystick, controlling the movement, back, back and neutral is also attached to the seat. It is also a 7-inch color display, which shows the fuel consumption reduction manual, a separate rear view monitor, as well as auxiliary connector and two 12-volt ports.

The company manager Rob Mac-Magon says that an improved loader has stability, increased brake and traction efforts that will allow the machine for a variety of tasks. For example, push gravel, transport pipes, work with landscaped materials and aggregates, as well as much more. Including, he noted that additional equipment and logging equipment are additionally available, and for working with waste.

Additional options include:

• The cover over the engine in the form of a seagull wing, which greatly simplifies access to the engine compartment for maintenance;
• Full-size rear wings;
• Sensor on the tank cover for DEF to avoid overflow;
• Additional panels on each side for easier access to consumables;
• Fans that have a larger pitch blades, as well as an automatic reverse system for easier cleaning.

The WA470-8 model is equipped with the Komtrax branded telemetry system, which allows operators, as well as fleet managers to monitor the level and consumption of fuel, work hours and location. As a result, they can determine the need for maintenance in advance, just following the information through a special website or through a smartphone.

It is worth noting that in this model the company added the ability to track the level of DEF, temperature and air pressure.

The Komatsu Care warranty is provided for the first three years of operation either by 2,000 hours and includes planned service at the factory, an inspection of 50 points with each planned inspection. And warranty service for DEF and DPF tanks is available for 5 years.
