Domestic and foreign manufacturers of construction machinery: Wheel Loaders

Loader – these modern high-performance machines designed for carry out excavation, loading and processing of different materials: different types of soils and rocks, coal, sand, gravel chips, metal chips wood, stone, etc. as well as agricultural products. In addition, the charger can handle the soil (earth mounds otsypku, axes), to work in bulldozer mode: site design and text shallow wells. Loader freight transport in the bucket digging or catching, towing trailers or other equipment for distances short.

Loaders, much smaller size and weight as the bulldozers can raise a much larger mass of the load, switching not need much space. It is these qualities and to establish its scope. Consequently, this transformation and working bodies – cubes.

Standard buckets (With a straight edge without teeth) are used in the transshipment of sandy soil, gravel and clay. These cubes are equipped with two replaceable cutting edges (solid or segments), made the strengthening of resistance have high hardness. cubes of the jaw to increase the height of tens of centimeters and allow pogruzchikam conduct discharge additional features (push and level the ground, filling the back, planning, making and bulk piece).

To evaluate the effectiveness of used wheel loader, two important features – the width and angle the mouth of the hub of Canada. Canada cube land angle greatly affects the degree of filling. The range of changes of angle zaprokidyvaniya different charger models front is wide enough (34 ° to the models of O & K at 53 ° of Caterpillar) and determined by the size of hydraulic cylinders and the type of swivel bucket. Depending on the destination handler used two types of mechanisms for turning the cube: Z-shaped, providing a greater separation of forces, and fit with a wider angle Canada H.

Modern wheel loader can be equipped with a variety of forklift trucks with jaws and without overloading for long, fibrous goods, and piece goods on pallets. Pnevmokolesnye Front loaders can also be equipped with hoisting equipment strelovym.

High truck Most lift loaders can be achieved through the framework sharnirno-sochlenennoy, which consists of two parts connected with the vertical axis together. framework rear provides for the installation of power plants, transmission lines, and the operator of the taxi in front – for the connection of the administration work gidrosistemoy and front axle. The fixing of the frames and turn to each other in two sledyaschego gidrotsilindrami controlled steering system that provides frame rate in turn the corner of the corner turning the steering wheel proportional, whose value ranges from 28 ° (Liebherr) at 45 ° (S & C) in each direction, but for the vast majority of machines is 40 °. All front wheel loaders is the head, which drive the creation of machines involved and cargo weight.

Strojarne Podpolianske Slovak plant (ZTS) Detva – the oldest Soviet-built provider. Detva charger good record in domestic locations. Recently, family of machines Detva United Nations and KNB replaced by a modern series of SET. old trucks equipped with engines and hydrostatic transmission Zetor, working together with the investor. The new trucks are equipped with Cummins diesel engines, change gidrotransformatorom and invest in the framework of four types of cargo Clark, front axle and rear differential, and aboard reduktorami stupichnymi multiple disc brakes, active in oil bath.

Kolodochny operated parking brake Hydraulic installed on the rear axle. Gidrorul Chargers equipped with a hydraulic pump to abort the independent electric motor, automatically reactivated when the pressure falls mainly on the power circuit. The machines have a malfunction of the monitoring system main units, to protect the ROPS, blocking motor when starting the transfer. Maintenance labor reduced the maximum, all the daily care and control with ease.

Production manager Huta Stalowa Wola plant are very popular among builders, as a model L-34, a leader in the biennium 97-98. by the number of new cars, located in Canada. To to consolidate positions in the global market for Huta Stalowa Wola organized a joint venture with Komatsu Dresser company – a company Dressta So. Ltd., which is responsible for providing of the brand teams Stalowa Wola.

trucks equipped with engines and Komatsu Summins Poland, speed gearbox reverse the axes of the differences and reduktorami global car. At the head of disc brake systems, dry gidroprivodom (eg, model 515S) and multi-disc brakes, active in oil bath (Model 560s). The basic principles of engineering technology, which depends on the reliability of Stalowa Wola technology has not changed, but otherwise the team has changed. Little by little, and having updated the design elements of the hull, Hydraulic Cutters, new, etc. A good example is a magazine of 534, soon replaced the known model L-34B, 520E also update the machine, first shown in 2000 at the World Bauma in Germany.

Serious attention the development of user-pays rule for Komatsu loaders, showing that this type of machines is one of the big corporations. In the tradition of continuity of solutions proven techniques that are changing to new models. The new device is the combination of the cost of the pumps that belong to different systems, the definition of a hub terminal, the high nitrogen compensating low frequency vibration bucket load while driving on rough roads. Should take into account the type of button Transmission of the reduction of 2 ° to 1, while filling the bucket with automatic transmission increases when I turn the progress and the tradeoff automatic or manual operation of the gearbox.

Usually the emphasis on ease of maintenance, including diagnostic activities, and reduce operator fatigue.

Fiat-Hitachi strongly represented in the front loader canada odnokovshovyh market, these machines occur in a wide range of mass and volume of the bucket. However, Fiat-Hitachi continues to develop its product range. The aim of the modernization of boots – the best of themselves for power, speed, stability and productivity, comfort and workability, durability and ease of maintenance, environmental safety.

The machines are equipped with diesel engines from Fiat Group, Fiat, Iveco, Cummins, Nissan, gidrotransformatorom, changing four frames under load, bridges the gap of increased friction planetary reduktorami car disc brake, established in oil baths in the head. The Office of the shifter – electrical, button. The automatic transmission chooses the load management, ensures the maintenance of the selected speed button lets you switch between 2 nd Transfer a 1-yu, and vice versa, when the engine slows down and blocks its release, when the transfer.

Nitrogen compensators, established in contours boom boom hydraulic cylinders, reducing the dynamic forces in the workshop equipment involved in road freight transport in the rough.

Chargers front up a significant portion of the production program at issue, is the highest among the largest producers of road construction equipment. As a company Energy uses its own diesel engine. The pair became gidrotransformatorom, frame shift under load for the electronic control and differential increased friction. Machines stupichnymi equipped multi-disc brakes, active in oil bath.

Reducing the burden of serving their teams – one of the points case application designers. To this end, the hydraulic cylinders are removable lid – screw the carrying capacity of oil and liquid equipped with an external level, the engine compartment lid is fixed in the open position, giving good access to aggregate data and service equipment monitoring is shown in the display panel for easy reading.

The Caterpillar company and its products, needs no introduction, and this fully applies to pnevmokolesnym bucket. Cars equipped with a Caterpillar diesel engine of its own production. Loader equipped gidrotransformatorom planetary gear automatic transmission loaded with electronic control, planetary and brakes car reduktorami stupichnymi oil immersed disc.

Some of Caterpillar loaders equipped with seizure standard fast organisms that includes work created over 50 titles, including sweeping brushes and asphalt cutters. Caterpillar drew attention a services system, which he calls "five." Along with the activities of the organization (dilerstva development services, a network of warehouses and others) to include and technical innovations in the machines themselves: the constant surveillance units, the diagnostic phase of the points in accessible locations, to simplify and facilitate prevention and repair.

Modern tiporazmerny a number of fairly large JCB front loaders with the company, unlike its competitors, never sought a rapid and complete replacement of all new production models. JCB uses a standard set of technical solutions in the design of front loaders pnevmokolesnyh. Diesel engine gidrotransformator time passes, then the box-load displacement, where the drive shafts that distribute between the bridges and differential planetary gear on board and presented at the wheel. wheel hub brakes equipped with multiple maslopogruzhennymi with gidroprivodom.

In the contours recovery boom hydraulic cylinder piston cavities constructed compensators nitrogen fluctuations workshop equipment, resulting in the movement vehicles with a bucket of water on the uneven surface.

JCB produces a group of shippers tiporazmernoy with Zy mechanisms in the form of H-turn the cube that extends to the choice for the customer.

Pnevmokolesnye loaders Liebherr German group belongs to one of the most representative of the families in this market. Liebherr builders greatly reduced the number of traditional solutions used in a new series of machines. By remaining include overall design framework becoming "izlomom" mechanical transmission gearbox to the drive wheels to the board the differences and reduction units, multiple brake maslopogruzhennye center, noise and vibration isolation booths. models of small and medium enterprises are still available with two options of the kinematic rotating the cube, all models can be equipped with a quick capture of replacement workers.

Technical innovations in the new generation of machines are: the engine radiator sent to the cabin, which was offset center of gravity once again made it easier to additional balances and increase the angle. The engine temperature is not affected because the cold air coming from the lateral sinus. Start the engine was made possible through the implementation of transmission hydraulics.

Test results on a real construction loader to confirm that a set of these and other efficiency measures will dramatically increase Liebherr machines, reducing cycle time and reduce fuel consumption by a fifth.

Volvo loader is also known to builders Canada. Pnevmokolesnye loaders has always been in the range of Volvo Construction Equipment significant role.

On the design front loaders pnevmokolesnye Volvo correspond to the traditional car sochlenennoy hinged frame, motor diesel (production), gidrotransformatorom transmission, differential and units board reduction, multiple maslopogruzhennymi stupichnymi brakes, comfortable cabin safety and development of automation of routine operations and staff support. The difference of the competing models are fully blokiruemye spreads over bridges and original mechanism zaprokidyvaniya cube.

Complex solutions techniques implemented in the Volvo loader, provides high-effort service, while maintaining the orientation of the body of work in space conditions ideal for full operator control over all units, the maximum automation of compliance with the regimes of speed and traction, the rapid succession bodies of work and low toxicity of escape.

CJSC "Petersburg Tractor Plant" is a subsidiary of OAO "Kirov plant." The plant currently front loader produces the series of K-702m-PC-6. Long experience confirms the high reliability, simplicity and convenience of service, efficiency in all modes of construction road.

Testing and will soon be put into production a new high performance loader pnevmokolesny against K-742, which has improved the consumer (convenience, safety management, modern design) and technical characteristics, improves productivity by increasing switching capacity and reduce the water cycle.

The high value vyryvnogo effort is provided by the equipment standard form charge Z hydromechanical transmission guarantees a high traction. Shirokoprofilnye tires and axle – a guarantee of a high cross on the floor sticky and soft. Chargers indisputable merits of Belarus – High speed, agility, performance, ease and convenience of handling, comfort and operator safety.
