Excavator based on MTZ 82 | Technical characteristics, applications

Bulldozer MTZ 82 (Belarus-82.1, MTZ-82P, Belarus 1221.2, MTZ-82.1-23 and analogues) 68,000.00 rubles

The Belarus 82 tractor is known for its versatility and wide applicability for many industrial, agricultural and domestic tasks. In many ways, this versatility is achieved due to the ability of the tractor to work with various attachments, which significantly expands its capabilities. Based on one chassis, it is possible to perform various tasks due to the attachment, from street cleaning to excavation work.

One of the popular solutions for this tractor model is bulldozer equipment. From us you can buy a new MTZ 82 at a favorable price, as well as purchase bulldozer equipment, which is installed as a front linkage and allows you to perform various bulldozer and leveling work. The requirements for this hitch are a tractor engine power of 16 hp or more. s., therefore MTZ 82 fully meets these criteria.

Application of the MTZ 82 excavator

An excavator based on MTZ 82 is used for:

loading and unloading operations in agriculture, construction, manufacturing. Mainly used for transshipment of bulk cargo;
excavation work on soils from categories 1 to 4 (clay, salt marsh, loam, chernozem, other unfrozen soils);
bulldozer work.

The areas of application of MTZ 82 are quite diverse. However, this technique is not suitable for all operating conditions.

Main advantages of bulldozer equipment

Ability to work with various loose working media using a conventional tractor: move soil, sand, gravel, snow, etc.
Quite wide technical capabilities of bulldozer shovels, comparable to the capabilities of a separate fully functional bulldozer.
Easy to install and operate, as well as high reliability and durability of the shovel design.
If you want to buy MTZ 82, the price together with attached bulldozer equipment will be quite acceptable.

From us you can buy MTZ 82 with all the necessary attachments at the best prices.

You can buy a bulldozer shovel for Belarus-82.1 at a price of 39,000.00 rubles. You can buy bulldozer equipment for the Belarus 1221.2 (MTZ 1221) tractor at a price of 75,000.00 rubles. For installation on the Belarus 82.1 (MTZ-82) tractor, buy bulldozer equipment with hydraulic rotation of the shovel is possible at a price of 68,000.00 rubles.

Excavator MTZ 82: technical characteristics

dimensions

Weight: operational - 7.2 tons; full - 8.4 tons.

Length - 6.7 m; width - 2.4 m; height - 3.6 m.

Units and equipment

The MTZ 82 excavator is powered by a four-cylinder D-243 engine with direct injection. The 4.8-liter diesel produces 81 hp/60 kW of power and 258 Nm of torque.

The equipment is equipped with a 9-speed manual transmission. Additionally, a gearbox is installed, which doubles the number of gears.

The backhoe loader is assembled from:

rigid tractor frame, which increases its maneuverability;
columns;
arrows;
jacks;
ladle.

Raising and lowering the boom, adjusting its reach, and turning the column are carried out using a hydraulic system. The jacks and the working element are also driven by hydraulics.

Additionally, the excavator based on MTZ 82 is equipped with:

hydraulic hammer;
grab;
hydraulic drill;
baking powder tooth.

Features of bulldozer attachments

There are several options for a mounted bulldozer:

rigid bulldozer - only the lifting height of the shovel from the ground level can change, while the shovel is rigidly fixed to the lifting mechanism;
a bulldozer with a mechanical rotation of the shovel, allowing you to change the angle of attack of the shovel;
bulldozer with hydraulic rotation of the shovel with fixation of the shovel in a given position after changing its angle.

At the same time, the cost of MTZ 82 when purchasing bulldozer attachments does not increase too much, but the functionality expands significantly.

The complete set of bulldozer equipment is selected depending on the chosen option. As a rule, the kit includes a bulldozer blade, a bulldozer shovel, and may also include hydraulic cylinders for lifting and turning the shovel. An important feature should be noted: this hitch can be installed not only directly on the tractor, but also as a replacement for the main bucket of loading equipment. Therefore, many enterprises prefer to buy MTZ 82 in Moscow with a hydraulic front loader, and in addition to this loader they select a bulldozer attachment to replace the standard bucket.

Step-by-step assembly of the structure

Rotary blade assembly sequence:

Blade design for tractor

To make the main part of the bulldozer, a steel sheet of the required blade size is cut out, and then it is given the optimal shape. The width of the shovel should not exceed the dimensions of the tractor by more than 400 mm on each of the two sides.
Two supports are created , to which stiffening ribs from plates are welded, and a hinge joint is installed at the bottom. The supports will be connected to the cross beam, and the entire structure will be bolted to the side members. A hinge is welded to the front of the beam for attaching the hydraulic cylinder.
A triangular semi-frame is made from two beams , on top of which a lifting hydraulic cylinder is installed. On the outer sides of the beams, in the middle of each, one hinge is attached.
The shovel is connected to the half-frame with two hinges. The first hinge is installed at the level of the hydraulic cylinder, and the second is 200 mm higher on a special support.
Hydraulic cylinders are installed parallel to the subframe. Attachments for them are made to the blade at a distance of 1/3 from the center on both sides. Rotating the blade provides greater functionality to the bulldozer.

A simpler method, if the bulldozer does not require adjustment of the blade position, is a fixed mount, when instead of hydraulic cylinders, two pipes are welded to the blade on the frame.

Types, advantages and disadvantages of homemade dumps

The design of the tractor blade should be selected depending on the planned work. There are several types of dumps for tractors:

Communal. It has a lightweight form because it is used mainly for cleaning hard-surfaced areas from various debris, as well as for landscaping livestock farms and other facilities.
Bulldozer. It is used not only for cleaning areas, but also during various construction works - road construction, planning areas where leveling and removal of the top layer of soil is required.
Snow removal. The design is similar to the communal type, only a technical rubberized plate is installed on the working part of the blade to avoid damage to road surfaces.

Advantages of homemade dumps for the MTZ tractor:

much cheaper than factory options;
independent selection of the most suitable materials and parts;
selection of optimal dimensions of the bulldozer design.

Flaws:

if the blade size is inappropriate, the bulldozer is overloaded, leading to serious damage;
lack of warranty service.
