Design, description of the loader and its features
The main characteristic qualities of the XCMG LW300F front loader include:
- high functionality;
- good performance indicators;
- ease of maintenance and repair;
- modern appearance;
- good maneuverability;
- compact dimensions;
- strength and reliability;
- unpretentiousness.
The main design features are the rear-mounted diesel engine and the articulated frame. Each type of work performed involves the installation of various equipment. As standard, a bucket with specific teeth is installed on the loader as a working tool. To replace this working body with another, no special skills or effort are required. This reduces downtime and makes the machine more versatile and multifunctional. Additional attachments XCMG LW300 allows you to use it not only for loading operations. The loader is equipped with a very useful self-leveling bucket function.
The standard loader bucket has a volume of 1.8 cubic meters and a load capacity of 3 tons. This bucket is no different from the standard equipment of previous models - with the same teeth and pins. The size is usually 60*185. Everything is the same - boom, rocker arm, hydraulic cylinder connection.
The loader has been modified compared to previous models from this manufacturer. But in general, it is distinguished by a classic design and the signature yellow color of XCMG equipment: the yellow color of the cab, hood, fenders and the rear of the loader frame. By the end of the 2010s, the company will add gray to its corporate yellow; and the letters will be written in blue.
The headlights on loaders of later years of production were equipped with protection, the headlights were located in a droplet on both sides, and the turn signals were on the reverse side, so that the operator could see whether his light was on or off. The headlight connector is standard, it is similar to the device of European technology (six contacts), so there will be no problems with the connection. The headlights, compared to previous models, have become stronger and more durable because they have been protected: compared to previous models, they had square block headlights. They were made of plastic, which bursts in the cold, which is why such headlights had to be changed periodically.
Boom side seals must be replaced periodically. On the right side of the frame there is a nameplate with information about: the model of the loader, its overall dimensions, frame and chassis numbers, operating weight, load capacity, power, year of manufacture, this information is also duplicated on the frame under the cab, and during hauling and (or) for Customs authorities place a sticker on the glass of the forklift.
The frame is fastened - a pin, two flanges, a bearing inside, these parts change in front in the upper part and in the lower part.
PGU - the main brake cylinder, which is responsible for the brakes of the front frame (this loader has two brake cylinders - on the front part of the frame and on the rear). Each part on the XCMG LW300 - no matter how big or how small - is marked with XCMG stickers with a code, which indicate the series, number, production batch and catalog number.
These loaders have a gearbox designed for operating equipment in urban environments. It is equipped with a low gear (the lever in the cockpit is marked “turtle”). And the transport position - for moving from object to object or quick work in a spacious quarry - is depicted as a “bunny”.
The manufacturer also offers a modification of the loader with an extended boom. The unloading height in this case increases to 3,220 mm, however, a loader of this type is equipped with a bucket of smaller capacity - a volume of one and a half cubic meters.
Fuel consumption data
A 150-liter tank is installed for diesel fuel, which allows the loader to operate for a long time without stopping. The XCMG LW300F loader is quite economical. During one hour of machine operation, approximately 215 grams of fuel are consumed. Such data is provided by the manufacturer at average loads on the power unit.
About the manufacturing company
XCMG (Xuzhou Construction Machinery Group, or, the Chinese name is Xugong Zituan) is a large Chinese corporation for the manufacture of heavy special equipment, a state limited liability company. It is consistently among the top five largest manufacturers of such products in the world, and in China it ranks first in terms of production volume of heavy special equipment. XCMG is headquartered in Xuzhou City, East China's Jiangsu Province.
The company has been operating since 1989. An important milestone in the development of the company was the agreement with Caterpillar, concluded in 1995. This gave a powerful impetus to the development of production and the introduction of new modern technologies. We started with the joint production of excavators and off-road truck cranes. Subsequently, cooperation was also established with Meritor, Cummins, and Liebherr.
For the first time, XCMG Corporation products officially entered the Russian market in 2000. However, at that time it was not yet distinguished by its impeccable reliability, and also did not always withstand the harsh climatic conditions of the Russian North or Siberia. Over time, the quality of XCMG equipment was improved: models were created that were able to solve any problems in any regions of Russia. At the moment, the annual export of heavy equipment of this brand from China to Russia has exceeded two thousand units. The Russian official distributor of the company is called XCMG RU and has its own network of dealers.
Calculation example
Improving the international image of XCMG, obtaining additional investments, introducing modern innovative technologies and increasing the level of its own production and management occurs through the creation of 16 joint ventures with such large manufacturers as Caterpillar, Liebherr, Meritor, ThyssenKrupp. Specific fuel consumption and engine power can be found in the maintenance instructions, which include data in the form of a specific fuel consumption curve constructed by the manufacturer’s specialists based on the results of testing the engine in various modes.

Dual Circuit and Standard Boom Optional System Specifications
In addition to the technical characteristics and functionality, the buyer of loading equipment is also interested in the issue of fuel consumption of this or that special equipment with an internal combustion engine. The costs of servicing a forklift, in addition to service stations and repairs, include fuel costs, which is reflected in the cost of work and goods. Fuel costs take up the majority of expenses for equipment maintenance. But, unlike a car, there are no clear standards for fuel consumption per 100 km for a loader. The manufacturer usually indicates this figure in grams per unit of power. Sellers of loading equipment, based on experience, tell the buyer completely different numbers, which may differ significantly from the indicators specified by the manufacturer. What's the matter?
