Technical characteristics of backhoe loaders based on MTZ: MTZ 82, MTZ 80 and MTZ 92 p

The MTZ backhoe loader is a universal special machine created on the basis of MTZ tractors that combines the functions of two units - an excavator and a loader. It is a pneumatic wheeled vehicle and has both front and rear attachments. Used to perform all kinds of construction, road construction and municipal work: excavation, cleaning and transportation of garbage, snow, etc. It is very popular and widespread in farms throughout the former USSR for its high power, reliability, ease of operation and unpretentious maintenance. It can also be called the Belarus excavator.

Features of backhoe loaders based on the MTZ tractor

MTZ backhoe loaders are produced in Belarus at the Minsk Tractor Plant - one of the world's largest manufacturers of agricultural and construction equipment. The popularity they have gained not only in their homeland, but also far abroad (France, Germany, a number of developing countries) is explained by the optimal combination of price and quality parameters of products.

Excavator equipment created on the basis of MTZ has a number of common distinctive features for all model lines:

The first is high reliability and wear resistance of all parts and components of the machine.
MTZs provide greater cross-country ability even in difficult road conditions.
Excavators can move at a relatively fast speed for such equipment - 40 km/h.
The machines have hydraulic control systems.
Absolutely all control occurs from the operator’s cabin, with several basic functions controlled via joysticks.
The machine is equipped with hydraulic retractable supports, which provide special stability when performing excavation work.
There are MTZ backhoe loaders that operate in confined spaces, for which several controlled modes of wheel rotation are provided, as well as adjustment of the position of the working body.
The rear attachment allows for excavation, and the front attachment allows for loading, unloading and other work. It is also possible to change the attachment to meet other needs (hydraulic hammer, forks, shovel, drilling rig, buckets of various configurations).
Some models are equipped with a telescopic boom, which provides increased digging depth. The versatility of the equipment is also achieved thanks to the presence of a quick-change double-jaw bucket of a special design, which combines the functions of four devices at once - a bucket, a grab, a bulldozer blade and a jaw grip.

IMPORTANT! The MTZ backhoe loader is favored by the availability and low cost of spare parts, as well as the ease of installation, which ensures a relatively low cost of any repair without contacting service centers.

Mtz 80

The MTZ-80 Belarus excavator is the base model for a whole line of special vehicles produced after the deep modernization of MTZ-50 tractors from 1974 to the present.

Excavator loader MTZ-80

Device

MTZ-80 is equipped with a 4-cylinder liquid-cooled diesel engine D-240 with electric start or D-240L with starting engine. The gearbox is automatic 9/2 (forward - 9, reverse - 2). The drive is installed only on the rear wheels, which in this model are driving, and the front wheels play a guiding role. The skeleton of the car is a semi-frame with a front-sprung suspension. The steering is carried out mechanically using a worm gear with a hydraulic booster to facilitate the operator's efforts to turn the steering wheel (helical sector). The excavator's design includes a front-mounted engine, larger rear wheels and an enclosed glass cabin. A larger front bucket, an additional trench bucket, and a rear-mount bucket attachment come standard.

General technical indicators

Earth-moving machines created on the basis of the MTZ tractor are classified as the second size group of excavators. A tractor with an operating power of at least 60 horsepower is used as a tractor. The excavator is manufactured on a reinforced frame. This made it possible to increase the total weight, so the equipment has optimal balance and better adhesion to the surface.

If a telescopic boom is used to attach the bucket, counterweights can be used. A backhoe or a straight shovel is usually used as a working element. Bucket volume 0.17 and 0.76 cubic meters. meters respectively. At the request of the customer, the equipment can be equipped with a larger volume excavator bucket.

The transmission includes an eight-speed gearbox, with reverse capability for each operating mode. The circuit is supplemented with a closed-type clutch and band brakes.

The technical characteristics of Belarus excavators can be considered using the example of EO-2621.

Structural mass	6,100 kg
Overall dimensions: length/width/height	6 480/2 200/ 3 800 mm
Ground clearance	450 mm
Working radius: forward/backhoe	4.7/5 m
Depth of excavation	3m
Basic bucket volume	025 cc m
Performance	40 cu. m/hour
Unloading height: forward/backhoe	3.3/2.2 m

The given characteristics are relevant only for this type of equipment! Considering that the model range of Belorus excavators includes several machines, the technical parameters differ!

The EO-2621 excavator is mounted on the YuMZ-6AL tractor and its modifications.

MTZ 82

This model of backhoe loader is also considered a basic model, along with the MTZ-80.

Design and operation

The main feature of the MTZ-82 is the presence of hydraulic control for all vehicle systems, including the steering. The hydraulics of the front linkage are connected to the hydraulic system of the tractor itself, and the movement of the boom and supports is carried out through an additional hydraulic system.

ATTENTION! A significant difference between the MTZ-82 and the previous modification with the index “80” is its all-wheel drive, that is, the presence of an all-wheel drive system on both the rear and front pair of wheels.

The mechanical transmission allows stable operation in various road conditions. The machine starts from an electric starter, and radiator devices are of oil and water type. Dismantling of the bucket linkage can be carried out without lifting lifts and additional working hands, as it takes place by installing a replaceable device on the front ends of the boom.

Models 82 and 92p

MTZ-82 is an improved modification of machine 80. It differs from the previous model in that the backhoe loader based on MTZ-82 already has hydraulic control. With its help, you can easily control all car systems, including the steering wheel.

The MTZ-82 excavator is also characterized by all-wheel drive on the rear and front wheels. This positive characteristic is noted by car owners in their reviews. The MTZ-82 excavator loader is equipped with a mechanical transmission, which allows the machine to operate in various weather conditions and on moving soil. The 82 excavator starts the engine via an electric starter; there are water and oil radiator devices.

MTZ-92p is a machine installed on the MTZ-82 tractor, created in Minsk quite recently for work in fields and city streets. It differs from previous modifications in its high level of stability on moving soil, which is why the machine of this model is more often used for digging than a backhoe loader.

The 92p model is smaller and more compact in size, which allows it to be used in limited conditions of construction sites. Often the machine is used in corner spaces or near fences, where other mechanisms cannot reach due to their massiveness. Among the features that turn this machine into an indispensable assistant at a construction site, at home and in the field, there is a movable and shiftable carriage.

Machine pitch up to 130 cm long. This allows you to dig trenches and holes up to 4340 mm deep. The excavator installation of this most compact mechanism is installed perpendicularly, while on other MTZ models it is mounted horizontally. As a result, the maneuverability of the 92p has significantly increased, its operation has become smooth, flexible, and accurate. The model is equipped with hydraulic cylinders and hydraulic distributors. The machine is controlled via two joysticks.

A separate wheeled excavator based on the MTZ-82 is distinguished. This technique is a hybrid because it has front-loading devices and the technical characteristics of a low-power tractor of a classic model. A popular model among buyers for several years now is the EO 2626, designed for excavation, loading, scraping, bulldozing and grab work. The EO 2626 is equipped with a backhoe bucket and a loading double-jaw bucket. The price of this model is slightly higher than regular ones, but its purchase justifies itself within a short time.

power – 65–90 horsepower;
vehicle weight – from 3 to 7 tons;
bucket volume – up to 0.4 cubic meters. meters;
boom reach 5 meters.

All MTZ models can reach speeds from 40 to 60 km/h. This is quite a high figure for an excavator. For all its advantages, it also consumes relatively little fuel.

Excavator loader based on MTZ-92p

Device

The machine is much more powerful than the MTZ-80 and MTZ-82 models and is very stable when digging. Several innovations made it possible to use the MTZ-92P even in confined areas of the city, in corners near walls and fences.

This is facilitated by:

The possibility of shifting the carriage by steps of up to 130 cm in length, at which the digging depth remains quite large - up to 4340 mm.
Laying of excavator equipment perpendicular to the direction of the tractor, unlike parallel for other MTZ models.

INTERESTING! By changing the way equipment is laid out, the overall length of the excavator has been reduced and its maneuverability has increased, which is very valuable when working on small construction sites.

The operation of the equipment on the MTZ-92P is very accurate and smooth, which is achieved by equipping the backhoe loader with an Italian-made hydraulic distributor. The presence of hydraulic cylinders eliminates the problem of oil leakage, and control is carried out by two conveniently located joysticks.

Mounted excavator for MTZ

This removable equipment allows you to turn the Belarus tractor into an excavator. Its advantage is its lower price than a real backhoe loader. It does not have the same power, but it is quite suitable for performing simple operations.

A mounted excavator will cope with digging trenches for foundations, for engineering and utility needs. The depth of the pit is just over 2 meters.

This equipment is universal and suitable for any model of MTZ tractors. It is reliable as it has retractable supports. This provides additional safety and tip-over protection. There is a function to shift the hitch relative to the tractor, which facilitates the digging process. The average weight of such devices is 600 kg, they are compact and can even be stored in the garage. Features simple controls.

This option is suitable for people who often face the need to dig up or move soil and other bulk substances, but these works are simple and do not require the high power of a full-fledged excavator.
