The MKSM-800 loader gained popularity in Russia, as it is known for its ability to perform various tasks, its small size, simple operation and maintenance, as well as its reasonable price and economy in the working process. This machine, along with other civilian and military equipment, is produced by one of the largest Russian manufacturers - the Kurgan Machine Plant.

Mini-loader MSKM-800 is used in all cases when strength and maneuverability are needed at the same time: in industrial processes and during construction work, when loading or unloading, it is used by utilities and various households, up to closed small spaces.

Navigation

It is worth saying separately about the small size and maneuverability of the MSKM-800 loader, since it is these qualities that are especially attractive when it is necessary to carry out work in small or covered rooms where the use of large equipment is impossible or considered irrational.

Peculiarities

How does the abbreviation MKSM stand for? It stands for "Multipurpose Communal Construction Machine". The number 800 included in the model name indicates the carrying capacity, the limiting capabilities of this technique.

In addition to the bucket, the basic loading configuration, about twenty other devices and auxiliary parts can be installed on the MKSM mini-loader. This transformation is carried out quite quickly, the new equipment is connected to the hydraulic system of the machine and is immediately ready for work. With such a complete set of attachments, this skid steer loader has earned a reputation as a multifunctional machine.

The technique is easy to maneuver and easy to operate, smooth running, as well as almost full turn around its axis, the machine provides a volumetric hydraulic drive and two final stepless gearboxes.

The machine itself, as well as the attached loading equipment, is controlled by the driver-operator from the cab. In it, for control, there are a pair of joystick levers, equipped with a mechanical and electrical drive.

The operator's cabin is designed for comfortable work at different times of the year and in different conditions: an almost all-round visibility allows the operator to control the situation around in the work process, and the heating of the cabin and the air conditioning system in it make the machine suitable for year-round use.

In poor road conditions (off-road, viscous deep mud, etc.), rubber-metal tracks provided by the design can be installed on the wheels of the machine directly from above. Thus, the machine evenly distributes the load on the ground and increases its traction and traction capabilities.

The small size and weight of this model of the loader make it possible, if necessary, to deliver it to the place of the forthcoming work using other large-sized cargo vehicles.

Technical specifications

Engine characteristics

MKSM loaders are equipped with various diesel engines imported from the USA, Japan and Germany. They vary in power, have a different cooling system and a different number of cylinders. All these differences determine the modification of the loader.

Performance characteristics

MKSM loaders, regardless of the subspecies of the model, have a bucket in their arsenal and have the same carrying capacity, however, the method of controlling the hydraulic system, the speed of the machine and the tractive effort of the loader differ depending on the modification.

Frontal mini-loader MKSM-800 is a special unit that performs multiple functions in the municipal construction sector. The main types of work include: planning the area for construction, loading and unloading a variety of bulk materials, drilling, shaping trenches and depressions in the ground, removing snow in winter, as well as performing simple work in warehouses.

The MKSM-800 multipurpose loader is manufactured by the Chetra group of companies. It gained its popularity on the market due to its relatively small size (compared to competitors) and the implementation of many simple, quick and necessary tasks in construction and utilities, where often large-sized equipment cannot be used for its intended purpose.

Review of loader MKSM-800

Description

This type of equipment, as we wrote earlier, refers to multi-purpose special-purpose equipment due to the large number of interchangeable equipment that is used to perform various kinds of tasks.

It is useful to know that the replacement of attachments on a mini-loader can be performed even by one operator, because the replacement technological process is quite simple and does not require special technical knowledge from the operating personnel. Moreover, the replacement of equipment is carried out in a short period of time, which is highly appreciated in the production of work!

MKSM-800 for organizations and entrepreneurs is an excellent option for work in "tight" overall conditions. There is always work for this type of equipment, which means that the loader will pay off very quickly, which is very, very profitable. I would also like to note that the cost of the work performed using the small-sized MKSM is significantly lower in comparison with other equipment.

Main features of the loader

The considered version of the equipment is deployed literally on the spot and by means of the volumetric hydraulic drive with infinitely variable speed switching included by the Chetra engineers in the list of equipment, it smoothly picks up and decreases the speed. The control is carried out by means of two joysticks, which is quite simple!

Compared with competitors' analogues (CASE 410 and Lui Gong 365A), the considered option has pronounced distinctive features and characteristics. Let's highlight some of them:

  • A quality engine from John Deere or Hatz, which fascinates us a lot.
  • Higher rates of cross-country ability and handling, even of a standard chassis.
  • Developed and installed volumetric hydraulic drive (we wrote about it just above).
  • Convenient location, and hence the use of controls.
  • Maintenance, daily inspection and repairs are made much easier due to design features.


Varieties

Today on the market there are not only standard MKSM-800 models, but also some of their modifications with various applications of the main components and assemblies. Let's describe each of them in more detail.

Model MKSM-800A - has a welded frame and a special clutch is installed for work at negative ambient temperatures.

Model MKSM-800K is completed only with a diesel power unit from the American company John Deere, in rare cases from Cummins.

Model MKSM-800N - is completed only with a diesel unit of the German company Hatz.

Model MKSM-800A-1 is the latest fresh modification with pneumatic wheels and tubeless tires, as well as improved chassis suspension.


Main technical characteristics of MKSM-800

The mini-loader, depending on the modification, is equipped with a power diesel unit, which has a specific diesel fuel consumption of 161.8 g / h.p. per hour or 220 g / kWh, which is quite economical.

How much does the MKSM-800 loader and its analogues cost?

Price loader MKSM-800 varies from 1 to 1.3 million rubles, depending on the choice of attachment equipment. The closest analogue - CASE-420 will cost you about the same amount of money. Naturally, we consider the price category for used equipment.

We hope that our brief overview has allowed you to draw the conclusions you need, stay ahead of us with a lot of different material and good luck!

The speed of development of the engineering industry is simply amazing. Now anyone can purchase the most convenient equipment for him, while not spending a lot of money on. Mini-loaders of the MKSM-800 type are especially popular, the technical characteristics of which can satisfy any road company.

Production

The Kurgan Machine-Building Plant has developed and produced a completely new machine that revolutionized the concept of construction equipment. This enterprise is one of the largest modern manufacturers in Russia. They produce both civilian equipment and are working on the development of some defense systems.

Mini-loader MKSM-800 is popular among both domestic and foreign consumers, all due to its compactness, high level of efficiency, and versatility. It should be noted that this special equipment is very easy to operate and maintain.

Scope of use

MKSM-800, the technical characteristics of which are suitable for performing almost any task, is used in a wide variety of sectors of modern industry, in construction, utilities and agriculture. The use of such a vehicle allows you to perform a fairly extensive range of services related to land management, loading or unloading operations. If there is a need to work in a rather limited space, then the choice is definitely for the MKSM-800. loaders allow you to carry out the task without unnecessary problems, even in closed rooms.

Control

To drive the hydraulic equipment of the machine, special joysticks installed in the inside of the cab are used. The controls can be communicated using an electronic controller or a cable drive. This parameter depends on the modification of the model and the preferences of the buyer.

The system has a common unit - a controller. Thanks to it, the loader has maximum maneuverability, while the driver does not need to put a lot of effort when working with the joystick. In the regulations that are supplied with the MKSM-800, the technical characteristics provide for the type of vehicle control.

Cabin

The MKSM-800 has a cabin made of an all-metal profile with additionally glued-in glass, as well as separate vents. This type of construction meets all modern safety requirements.

If we consider the cab separately, then it is already a pre-assembled unit, in which all the necessary controls are installed, as well as the climate system and display elements.

The frame is able to protect the worker from falling materials, as well as save his life in the event of a rollover. On MKSM-800, cab parts are in separate demand, since it is subject to various kinds of loads and sometimes is not able to withstand another blow.

The interior is made using modern materials to protect it from noise and dust. Inside, molded plastic panels are used, created in accordance with the design, which also meet the parameters of the life support of a person who works on such a technique.

Maintenance

Due to the simplicity of opening the hood, as well as raising the cab, the craftsmen have excellent access to almost all the necessary components and assemblies. This allows for a fairly quick replacement of a faulty element and carry out work related to the maintenance of the MKSM-800. Spare parts are installed just as easily as they are dismantled. Thanks to this opportunity, the forklift has won the honor and respect among the road and construction companies.

Engine

On the MKSM-800 loader, depending on its model and modification, a diesel power unit of American production of the Cummins brand, or of the German Hatz can be installed. They differ in power, as well as in the way of cooling. The American has 51 horsepower, while the German has 52.9. It is worth noting that the first one is cooled thanks to the use of a liquid system, and in the second - an air one.

Dimensions (edit)

All basic dimensions and weight of most of the MKSM-800 modifications do not differ from each other. The only exception is the model with the "A" index. The last car has a larger track width (equal to 145 cm), while the rest of these have a gauge of 141 cm. Other dimensions are also different. The length of the MKSM-800 A is 264.5 cm, instead of 248.0, as in the others, the width is 172 cm versus 168 cm. The height differs slightly, version "A" is one centimeter lower - 205.5 cm. Versus 206.5 cm. As a result of the increase in dimensions, the weight of the machine has also increased. The "A" configuration has a mass of 3.1 tons, the standard one - 2.8 tons. For the "A" version of the MKSM-800 loader, the repair may differ, since other sizes provide for a slightly different placement of the vital organs of the machine.

Equipment

Depending on the field of application of the machine, a wide variety of attachments can be installed on the MKSM-800. All additional bodies are created of two types: a quick-clamping boom, working in tandem with mass-produced modules, as well as a separate device for installing additional devices, which allows you to work with attachments from imported machines. This capability makes the MKSM-800 more versatile. There is no need to buy expensive imported equipment for a separate working device.

Attention should be paid to the additional set of tracks, which is supplied with the MKSM-800. They are installed in order to significantly increase the traction and coupling parameters when driving on the ground with a very weak bearing capacity. Tracks significantly increase the machine's cross-country ability, all due to a decrease in the specific pressure on the soil, and the presence of special lugs improves the grip characteristics.

Installation is carried out directly on the tires. To avoid touching the tracks and the side of the loader, the track width is increased. This is possible by installing additional attachments placed on the hubs.

The track width is no more than 340 mm, while the specific pressure on the soil is only 0.5 kg per square centimeter. The weight of the additional module may vary, but not more than 117 kg.

Price

Despite the popularity of the MKSM-800, its price is not so democratic and can vary, depending on the type of power unit. The version with will cost about 1,419,000 rubles, while the version with the Hatz power plant is slightly more expensive than 1,597,000 rubles. But one and a half million for MKSM-800 is not the final price. Depending on the type and type of work, the appropriate working equipment is also selected, for which you also need to pay separately. For example, a conventional bucket with a volume of 0.46 cubic meters. will cost 25 thousand. More complex modules cost the same: 360 thousand for a hydraulic hammer and 230 thousand for a hydraulic hammer.

Technical description of units

The travel drive of the MKSM 800 mini loader is provided by a transmission with a Zetor 5201 diesel engine, which is rigidly connected to the pump drive and to the NPA 33 movement pumps and the U32l working equipment pump. ... The oil cooler for the hydraulic system and the radiator for the cooling system of the skid steer are located in front of the engine. The fuel tank is located on the right side, the hydraulic tank on the left side in the inner frame. The RSK16T3 distributor is located in front of the NPA 33 variable pumps under the hydraulic filter of the working fluid. To provide convenient access to individual units of the MKSM 800 loader, the safe type cab is tilted after preliminary disconnection of the hinges in the loader cab. The cab contains all the controls and controls, instrumentation and the operator's seat. All this together forms a single assembly unit. The loader wheels are attached to final drives, which are attached to either side of the loader frame. Heating is located on the left side of the cab from the inside. The batteries are located on the right and left fenders. Access to them is possible after lifting the covers, which are equipped with a motorcycle lock.


Mini loader MKSM 800 is equipped with a Zetor 5201 diesel engine, which is elasticly installed. The engine is accessible from the rear after lifting the rear radiator shroud and from the top after tipping the bonnet and cab. It is a direct injection, four-stroke, three-cylinder, water-cooled diesel engine. The crankcase of the crankshaft is cast from gray cast iron, one-piece, with a flange for mounting the pump drive. The cylinder head is independent for each cylinder, the cylinder liners are replaceable.

The engine cooling system is liquid with forced circulation and with a thermostat. The circulating pressure lubrication system with a wet bath, the MKSM loader is equipped with a two-stage or replaceable oil filter. The fuel delivery system consists of a fuel pump, a mechanical all-mode regulator and a fuel priming pump. The Zetor 5201 engine is cooled with a forced circulation liquid provided by a centrifugal pump mounted on the front of the crankcase and driven by a water pump via a V-belt drive. The cooling system includes a small circuit with a thermostat that quickly heats up the motor to an operating temperature of up to 80 degrees. The filler cap is located on top of the radiator, the coolant drain cock is located on the lower left side of the radiator. The power supply system of the MKSM loader consists of a fuel tank, a fuel supply system on the engine and fuel pipes. The fuel tank is located on the right side of the rear with a filler neck behind the cab. The fuel tank has a capacity of 55 liters. From the bottom of the tank, fuel is sucked in by the fuel priming pump through the fuel line. A coarse fuel filter is installed on the lower part of the fuel priming pump. From the fuel priming pump, diesel is pumped into the Motorpal fuel pump through a single-stage fuel filter. The fuel pump delivers fuel through the high pressure pipes to the injectors. Excess fuel from the engine injectors flows back to the fuel tank via the return line.

MKSM 800 loader hydraulic system

Serves to drive the working equipment and the running gear. It consists of two hydraulic circuits: the implement circuit and the trolley drive circuit.

MKSM 800 working equipment contour

Consists of U32l pump, RSK16T3 three-section distributor, two hydraulic cylinders for raising and lowering the boom and two hydraulic cylinders for opening and closing the bucket. This circuit is protected by a pressure of 16 MPa at an engine speed of 1500 rpm by a safety valve on the RSK16T3 distributor.

MKSM 800 stroke drive circuit

Consists of two hydraulic pumps NPA 33 and two hydraulic motors MPA 33. This circuit is protected by a pressure of 35 MPa by means of high pressure safety valves built into the MPA 33 hydraulic motors. The working fluid tank, radiator and filter are common to both circuits. The hydraulic tank has a capacity of 55 liters.

Pump drive MKSM 800

Serves to transfer torque from the engine through the clutch to the adjustable pumps NPA 33, which ensure the movement of the loader by means of hydraulic motors MPA 33, as well as to the gear pump U32L, which serves to power the hydraulic cylinders of the working equipment.

The pump drive consists of a power take-off and a clutch, which together form one unit.

Controlling the pump drive is reduced to disconnecting it from the engine, especially to facilitate starting the engine at lower temperatures. This operation is performed mechanically with the clutch pedal located in the operator's cab.

The MKSM 800 loader drive is hydrostatic. The power unit is a Zetor 5201 diesel engine, the power of which provides optimal dynamic parameters of the loader during operation. The torque from the engine is transmitted through the flywheel and the clutch to the pump drive. The clutch is single-disc, disengaged with a pedal in the operator's cab. It serves to disconnect the pump drive in order to facilitate engine starting.


The pump drive crankcase is equipped with flanges for fastening two adjustable pumps NPA 33, which provide a drive for the chassis, and one gear pump U 32l, which fills the hydraulic system of the working equipment. From the variable hydraulic pumps, the torque is transmitted hydrostatically to the MPA 33 hydraulic motors by means of high pressure hoses. From the hydraulic motor, the torque is transmitted to the final drives by means of gears that are located between the hydraulic motors and the final drives. The design of the gear assembly allows the loader to be braked by the force of the Belleville springs. The loader is braked by means of a safety lever that is mechanically connected to the parking brake bypass valve when the safety ramp is folded back. The bypass valve allows pressurized oil into the drain line of the hydraulic system (which releases the loader), causing the loader to brake. The raised safety arm protects against spontaneous or uncontrolled movement of the MKSM 800 loader.

MKSM 800 loader control

The control of the MKSM 800 loader is structurally different from the loaders produced at the present time. One-handed movement control - with the left hand, control of the working equipment, including the bucket, is carried out with the right hand.

Attention! When learning to operate the MKSM 800 loader, the levers and handles must be moved carefully. The clutch is allowed to be used only when starting the engine in cold weather, while the clutch can be depressed for a maximum of 1 minute. Never use the clutch while the engine is running. In this case, this threatens the destruction of the clutch with the bearing.

Starting the engine at low temperatures.

When operating the MKSM 800 loader in winter conditions, changing the oil and oil filter at the intervals recommended by the manufacturer plays a very important role, since it may happen that the viscosity of the oil increases during operation. Thus, the thickened oil flows around the engine oil filter when starting the engine, which ultimately means that the oil enters the engine without filtration. As a result, engine wear increases several times.

A prerequisite for starting the engine at temperatures below -5 is to replace the oil with 10W30, the cooling system must contain a liquid with a freezing point of -25 degrees. The hydraulic system must be filled with VMGZ oil.

It is recommended to build an electric antifreeze heater into the motor block on an external 220V power source, which preheats the coolant to a temperature that meets the summer operating conditions of the MKSM loader. It is recommended to switch on the dipped beam for a short time before starting. It is imperative to squeeze the clutches to disengage the hydraulic pumps and the pump drive.
