This type of machinery is the second largest in the world market of the basic types of road equipment. Versatility of this equipment not only in the possibility of its widespread use, but also the ability to collate it various types of Equipment: bucket, forks, crane attachments, etc. The most important characteristics that contribute to the massive development and use of wheel loaders, are: – the ratio of real duty truck to its mass in 2 – 2,5 times higher than that of similar excavators – the higher mobility and maneuverability characteristics that enable one machine to perform loading and transportation work – the unit cost of wheel loaders, attributed to one cubic meter bucket capacity, 1,5 – 2 times lower than that of excavators – comparable quantities of separated efforts in Bucket wheel loaders and excavators (with equal capacity bucket) – the closeness of the coefficient of filling the bucket from the loader and excavator, which is usually 0,75 – 0,8, at least 1,0 – 1,1. Typically, wheel loaders shovels Trucks are based on four-wheel drive chassis with 4×4. Wheel loaders are equipped with front placement of the loading device and rear engine, which acts as a counterweight. Also the most commonly used structural variants in the Chinese trucks are: installation of diesel engines with a high safety factor of torque, equipped with electronic fuel injection system and meet international standards for environmental exhaust; use of hydromechanical transmissions with 3 – 4-band planetary gearboxes and much more.
Front loaders compare favorably Excavators Firstly, the size – they are much smaller. Secondly, they take on more cargo. It is these characteristics and to identify areas of use and versatility of these machines. Therefore, a huge variety of different and loader bucket. Standard buckets (with a straight cutting edge without teeth) are used for transhipment of sand, gravel and clay soils. These buckets can also equip oneself removable double-sided cutting edge (Full segment) made of a hardened wear-resistant steel with high hardness. Jaw Buckets increase the height of the landing on dozens of centimeters and allow loaders perform additional functions (Pushing and leveling the soil, backfill, layout, capture bulk and general cargo).
At the present stage of development of wheel loaders can be equipped with not only a bucket, but the forks with grab jaws or without them. There are also trucks filled with boom equipment for moving containers. Most cross-sets of front loaders is obtained by pivotally Articulated frame, which consists of two parts connected by a hinge with a vertical axis. The rear frame is designed for mounting power plant, transmission, rear axle and cab, front – to fix working equipment with hydraulic control and the front axle. Fixation and rotation of frames relative to each other is achieved by two hydraulic cylinders, the steering system, servo type, providing relative rotation of frames at an angle proportional to the angle of the steering wheel. All-wheel Chinese front-end loaders are leading, which is why in the creation of traction involved weight machines and transported cargo. Types of forklifts XCMG In connection with great potential for ispolzovniyu trucks produce them in three main categories – diesel and gas (so-called trucks) and electric. Of course, that the decision that purchase lies entirely on the buyer, that is to be clear about exactly will operate this vehicle.
