Fifth Wheel Operation

The 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, metal shavings, wood chips, stones, 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 shallow wells of text. Loader can transport goods in the excavation bucket or capture, tow trailers or other equipment for short distances.

Loaders, much smaller size and weight of the blades can raise a much larger mass of the load does not need to maneuver much space. Are these qualities and to establish its scope. Consequently, this transformation and agencies working - cubes.

standard cubes (with a straight cutting edge without teeth) are used in the transshipment of sand, gravel and clay soils. These buckets are equipped with two replaceable cutting edges (solid or segments), fact strengthen resistance have high hardness. cubes increase the height of the mandible by tens of centimeters and allow discharge pogruzchikam perform additional functions (push and leveling the ground, filling the back, planning, taking the bulk and piece goods).

To evaluate the effectiveness of the used wheel loader, two important characteristics - width and angle of the mouth hub of Canada. Bucket angle canada land greatly affects the degree of filling it. The range of changes zaprokidyvaniya angle from different models of loaders is large enough (34 ° to the models of O & K at 53 ° of Caterpillar) and determined by the size of hydraulic cylinders and the type of mechanism by turning the cube. Depending on the destination handler used two types of mechanisms to turn the cube: Z-shaped, providing a greater separation of forces, and H-shaped with a larger angle of Canada.

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

High forklift 's front Most chargers can be achieved through the framework sharnirno-sochlenennoy, which consists of two parts connected together with the vertical axis. Rear frame provides for the installation power plants, transmission, axle and the operator cab, front - for the connection of work equipment gidrosistemoy management and front axle. Fixation and turn them into two frames between steering system controlled gidrotsilindrami sledyaschego type that provides frames to turn the corner in the corner by turning the steering wheel proportional, whose value ranges from 28 ° (Liebherr) at 45 ° (O & C) each way, but for the vast majority of the machines is 40 °. All wheel loaders front are lead, participating in the creation of thrust and weight machines of cargo.

Strojarne Podpolianske Slovak plant (ZTS) Detva - the oldest supplier of Soviet design. Charger Detva good record in indoor places. Recently, machines Detva families of the UN and replaced KNB by a modern series of SET. Old trucks equipped with engines and hydrostatic transmission Zetor, working with the investor. The new trucks are equipped with Cummins diesel engines, four bullets gidrotransformatorom and reverse type load change under Clark, front and rear axles with differential, and aboard reduktorami multiple disc brakes stupichnymi, active in oil bath.

Kolodochny parking brake with hydraulic drive installed on the rear axle. SET loaders equipped Gidrorul with an electrically driven hydraulic pump abort independently automatically reactivated when the pressure falls mainly in the power circuit. The machines have a malfunctioning control system main units, to protect ROPS, engine block when the transfer begins. Maintenance work reduced the maximum of all daily care and control facility.

Plant production Charger Huta Stalowa Wola are very popular among builders, L-34 as a model leader in the 97-98 biennium. by the number of new cars, set in Canada. In order to consolidate global market positions held Huta Stalowa Wola a joint venture with Komatsu Dresser - So Dressta company. Ltd., what is responsible for providing brand teams Stalowa Wola.

trucks equipped with engines from Poland Summins gearboxes or Komatsu, reverse speed, shaft drive with differential and planetary reduktorami. In the joint chief Dry disc brakes with gidroprivodom (eg, model 515S) and multiple-disc brakes, active in oil bath (model 560s). The basic principles of engineering technology, of which depends on the reliability of Stalowa Wola technology has not changed, but otherwise the team has changed. Slowly, and with updated design elements Hull, hydraulics, a new cutters, etc. A good example is a manager of 534, soon to replace the known L-34B, will also be updated 520E machine, which premiered in 2000 at the World Bauma in Germany.

Serious attention to the development of rule applications user pays Komatsu loaders, showing that this type of machine is one of the big corporations. In the tradition of continuity of proven technical solutions that are changing to new models. The new device combines the cost of the pumps that belong to different systems, the definition of a hub terminal, the high vibration compensating nitrogen low frequency of cargo hub to drive on roads in poor condition. Please note the type of button to reduce the transmission from 2 to 1, while filling the cube with the automatic transmission increases when you turn back the progress and the choice of automatic or manual mode of operation of the gearbox.

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

Fiat-Hitachi overrepresented in the market odnokovshovyh Canada have front-end loaders, these machines come in a wide range of masses and the 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 ease work, durability and ease of maintenance, environmental safety.

The machines are equipped with diesel engines of the Fiat Group, Fiat, Iveco, Cummins, Nissan, gidrotransformatorom, four bullets under load changes, bridges the gap reduktorami increased friction drive planetary and multiple-disc brakes, established in the oil baths in the head. The Office of the shift lever - electric button type. Automatic transmission, load management chooses, sailing for maintaining the selected speed button lets you switch the 2nd transfer to 1-yu, and vice versa when the engine slows down and blocks its release where the transfer.

Compensating nitrogen, established in the boom boom hydraulic cylinder contours, reduce the dynamic forces workshop equipment involved in road freight transport in the rough.

Front loaders up a significant portion of the production program Case is among the highest among the largest producers of road construction equipment. As an energy company uses its own diesel engines. Torque becomes gidrotransformatorom, loaded frame shift to the electronic differential control and increased friction. The machines are equipped stupichnymi multiple disc brakes, active in oil bath.

Reducing the burden of service of its machines - one of the subject areas of application designers. To this end, hydraulic cylinders are removable lid - screw the driving ability of foreign oil and equipped with a liquid level indicator, cap Engine compartment is adjusted to the open position, giving good access to the aggregate of services, and data monitoring equipment that appears on the display board instruments easy to read.

The Caterpillar company and its products, needs no introduction, and this fully applies to pnevmokolesnym charger front. Cars equipped with a Caterpillar diesel engine of its own production. Automatic gearbox equipped Charger gidrotransformatorom loaded planetary transmission with electronic control, reduktorami planetary drive multiple disc brake and stupichnymi bath oil.

Some of Caterpillar loaders equipped with rapid seizure bodies working standard set that includes over 50 titles, including brush cutters sweeping and asphalt. Caterpillar drew attention to service system, which he calls "five." Along with the organizational activities (development of dilerstva service, a network of warehouses and others) to include technical and innovations in the machines: the units of constant surveillance, diagnostic removal of the points in places accessible to simplify and facilitate prevention and repair.

Modern tiporazmerny a number of JCB loaders quite extensive, with the company, unlike its competitors, has never sought speedy and complete renovation of all the new models. JCB uses a standard set of technical solutions in the design of the pnevmokolesnyh loaders. Engine diesel gidrotransformator time passes, then the scroll box load, where the cardan shafts that distribute between the bridges and planetary gear differential, and aboard are presented in the driving wheel. wheel hub brakes equipped with multiple maslopogruzhennymi with gidroprivodom.

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

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

Pnevmokolesnye loaders Liebherr German group belongs to one of the most representative of families in this market. Liebherr Builders greatly reduced the number of traditional solutions used in a new series of machines. By remaining include the general provision, making "izlomom" frame, transmission mechanical gearbox with differential driving wheels and reducing on-board units, multi-axis maslopogruzhennye brake noise and isolation booths vibration. models of small and medium enterprises are still available with two options for the kinematic rotating the cube, all models can be equipped with a quick capture of the replacement workers.

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

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

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

On the design front loaders pnevmokolesnye correspond to the traditional Volvo cars with frame sochlenennoy hinges diesel engine (own production), transmitting gidrotransformatorom, differentials and reducing on-board units, brakes stupichnymi multiple maslopogruzhennymi, comfortable cabin safety and development of automation of routine operations and support workers. The difference between the models of the competitors are the differentials blokiruemye front of bridges and completely original zaprokidyvaniya mechanism bucket.

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