Review of the Belarusian front loader from the MoAZ plant

To buy a high-quality front loader that can handle even rocks and frozen soil, you don’t have to go far. It is enough to turn to the famous Belarusian plant MoAZ, which has already proven itself excellent: its equipment works perfectly in the most difficult conditions.

MoAZ loaders

The MoAZ front loader is produced at the Mogilev Automobile Plant. Production facilities, as well as main representative offices, are located in Belarus. The plant was founded in 1935, and since 2006 it has become a branch of BelAZ OJSC. Later, a restructuring was carried out and the company became a branch of the BELAZ-HOLDING holding.

Highly qualified engineers use modern developments and create construction equipment that is considered one of the best in the world. Due to its characteristics and reliability, the equipment is widely used in Siberia, as well as in the Russian Far East. It is used for laying roads, developing oil and gas fields, and is especially popular in quarries or when working in underground deposits.

Among the front loaders, we can highlight the basic model MoAZ-40484. Based on it, modifications have been developed that have several development options.

The first option is to convert the loader into a bulldozer by replacing the working element. The second option is to increase engine power, which entails improved driving characteristics and operating speed.

The MoAZ loader is an all-terrain chassis with all-wheel drive and a loader boom in the front. Mainly, due to its power, it is used in quarries and the mining industry.

Possibilities

It is used mainly in quarries for loading semi-rocky and rocky rocks that have been previously blasted or loosened. It also works with light and loose rocks that are removed from the pillar. Thanks to its high breaking force, it is capable of not only loading a vehicle with a carrying capacity of more than 3.5 tons, but also being used as a bulldozer.

MoAZ 40484 description

The front loader MoAZ - 40484 is designed for loading blasted or loosened semi-rock and rock, as well as light and loose rocks selected from the pillar. This is a powerful, rigid, stable vehicle with an articulated frame, equipped with a hydraulic transmission and two drive axles, and has excellent maneuverability and high traction performance. An electro-hydraulic transmission control system, a hydraulic loader control system, service, parking and emergency brake systems with pneumatic drive, as well as an enclosed cabin with heating and ventilation create comfortable working conditions for the driver. Wide versatility of use is ensured by the ability of the loader to load vehicles with a lifting capacity above 3.5 tons. It is equipped with loading buckets with increased volume and various cutting edge options

Assembly and assembly-welding equipment (conductors, stands, installations) is specialized, designed for the manufacture of products of one standard size or a group of similar products. However, assembly equipment components (installation and fastening elements, rotating devices, bases) have universal significance and are used in various assembly equipment. Universal prefabricated fixtures for welding production are a set of normalized parts and assemblies, from which fixtures for assembling and welding various welded assemblies are repeatedly assembled. After manufacturing a batch of welded assemblies, the fixture is disassembled, and the parts and assemblies are used to assemble new fixtures. Universal prefabricated devices are most rational in single, pilot and small-scale production, when using special equipment is not economically profitable.

Design features

The loader chassis consists of two parts, which are connected by a hinge and controlled by hydraulics. There are two driving axles in this machine, which ensures high cross-country ability. The boom is mounted at the front and extends forward, which is what makes this a front loader.

The hydraulic pump takes power from the main engine and performs a wide range of tasks. It provides power to such important components of the loader as the brake system, steering, hydraulic system of the loader boom, as well as the electro-hydraulic transmission.

In a steering system, hydraulics are essential so that they can provide enough force for smooth and precise turning.

The transmission also provides a smooth change in speed, which is very important for the accuracy of the work performed.

The enclosed cabin has a comfortable, adjustable seat and a heating and ventilation system. This will provide the necessary comfort to the operator.

Modifications

Let us give an example of several modifications, as well as briefly the main distinctive characteristics:

• MoAZ-40483 has a more powerful engine, which increases the maximum weight of the load, as well as the time it takes to lift the bucket. The loader is equipped with a YaMZ-7512.10 engine with a power of 254 kW. Its carrying capacity is 8 tons.
• MoAZ-40483-030 is the basic previous version, but with an even more powerful power unit - YaMZ-7512, which has a power of 294 kW.
• MoAZ-40486 and MoAZ-40489 are bulldozers based on a standard chassis from the MoAZ 40484 front loader.

It is also possible to install different working parts and change some components of the loader. However, this is already carried out on special orders.

This Operating Manual (OM) is intended for operators and mechanics involved in the operation and maintenance of MoAZ-40484-21 wheeled front-end loaders, hereinafter referred to as “loader,” manufactured at the URP “Mogilev Automobile Plant named after. S.M. Kirov." The OM consists of the following parts: — description and operation; — design and operation of the loader components; — intended use; — loader maintenance; - storage; — transportation; - disposal; - applications. Persons who have the appropriate driving license, determined by their registration authority, as well as a certificate of study of the device, operating rules, repair, and maintenance of the forklift and who have been instructed in safety, labor protection, and fire safety are allowed to operate a forklift. For successful and safe operation of the loader, the operator must study this manual and the Operation and Maintenance Manual for YaMZ-238B engines and follow their instructions. Due to the constant development of the loader, the design of its individual assembly units and assemblies may differ slightly from what is described in this Manual.

PART 1. DESCRIPTION AND OPERATION

1.1 PURPOSE OF THE LOADER

The loader belongs to off-road vehicles and is intended for operation outside the general highway network - on quarry roads with a permissible axle load of up to 270 kN and having longitudinal slopes on dry and hard ground of no more than 15%, transverse slopes of no more than 12%. The MoAZ-40484 loader (Figure 1.1) with a lifting capacity of 7.5 tons and a bucket volume of 3.75 m3 is designed for loading bulk and lump materials with a maximum size of pieces up to 800 mm to perform excavation, transport and loading work on soils of categories I-II without preliminary loosening and on soils of categories III-IY with mandatory preliminary loosening. The loader can be used in hydraulic engineering and land reclamation, industrial, energy, road construction, mining and construction materials industries. The basic tractor for mounting loading equipment is the two-axle tractor MoAZ-69084.
