Mounted equipment with a height of not more than 25 meters is possible.

Model Benefits

One of the advantages of the Ulyanovsk MKT truck crane model is a microprocessor-type load limiter. It is designed to monitor the load level of the crane. With it, control the reach and length of the arrow. Sensors display the load based on the weight of the load on the hook.

With the help of a microprocessor, you can set the coordinates by which the crane operation area will be limited in conditions of limited space or while working in the area of ​​​​power lines. With the help of modern equipment, the microprocessor unit can be located far from the sensors in a place convenient for the driver in the working cabin, since the data is transmitted digitally.

Automobile crane MKT-25.1 "Ulyanovets" with a carrying capacity of 25 tons is mounted on a KamAZ-55111 chassis.

Crane mechanism drive - hydraulic from pumps driven by the chassis engine. The hydraulic drive provides ease and simplicity of crane control, smooth operation of mechanisms, a wide range of operating speeds, and a combination of crane operations.

Crane boom - telescopic three-section. The extension of the boom section is carried out by a hydraulic cylinder. To increase the space under the truck crane, by special order, a light lattice boom extension (gooseneck) is supplied.

The microprocessor-based load limiter with digital information display allows you to monitor the degree of loading of the crane, the length and reach of the boom, shows the actual amount of load on the hook, and automatically limits the crane’s coverage area according to the specified coordinates when working in cramped conditions (coordinate protection) or in the area of ​​​​power lines (MZON).

Crane lifting characteristics

Diesel-electric crane installation MKT-40 is a superstructure mounted on a semi-trailer. As a tractor, a MoAZ-546 model vehicle, originally designed to work as part of a scraper, is used. The MKT designation is also used for wheeled hydraulic cranes supplied to the market under the Ulyanovsk brand. Machines are united only by the name and purpose, the design has big differences.

MKT-40

The MKT crane consists of a rotary section mounted through a full-turn shoulder strap on a 1-axle platform. The front part of the chassis is equipped with a bracket that is mounted on the towing vehicle saddle. On the undercarriage there is a stand necessary for laying the boom when the crane is moving on public roads.

The rear axle of the chassis is equipped with a drive that includes an AC motor. Electricity comes from a generator, the rotor of which is driven by the power unit of the tractor. To transfer torque from the motor, a transfer gearbox is used. The drive is switched on by the tractor driver; mode is used only when driving short distances at a speed of 4.5 km/h.

MKT-6-45

The MKT-6-45 crane is a modernized version of the model 40 machine, adapted to perform work during the construction of oil and gas industry facilities.

As a tractor, a 1-axle MoAZ-6442 model was used, equipped with a 4-stroke diesel engine YaMZ 238M2, developing power up to 240 hp.

Crane equipment has undergone changes: the base boom has a length of 15 m, but by using inserts it can be increased to 43 m. Two versions of extension sections have been produced - 5 and 8 m each.

MKT-25.1- This is a truck crane designed to perform loading and unloading operations, as well as performing various assembly operations with loads whose maximum weight does not exceed 25 tons. Also, due to its lifting capacity, the MKT-25.1 crane unit can be used for pre-assembly.

For productive work MKT-25.1 equipped with a three-section telescopic boom. This boom is not only not inferior to the two-section boom (used in earlier models of truck cranes), but also surpasses in length and lifting height. The hydraulic drive sets in motion all the working mechanisms of the lifting equipment. Such a system allows not only to maintain high rates of crane operations, but also ensures the smoothness of their execution, and also guarantees the combination of several crane operations, which significantly affects productivity and makes work on the MKT-25.1 crane more convenient. To increase the space under the boom, it is possible to complete it with a lattice extension (jib). It is able to significantly increase the length of the boom, but reduces the lifting capacity of the MKT-25.1.

Truck crane MKT-25.1 mounted on a KamAZ-65115 truck chassis with a 6x4 wheel arrangement - this allows not only to ensure stability in operation, but also throughput, due to which, the operation of the crane installation of this model is carried out almost everywhere. As a power unit, the MKT-25.1 has a diesel engine 740.11-240, which produces a power equal to 240 horsepower. The design of the wheels is also well thought out. The installation of disk wheels with ten-pin fastening to the hubs led to the elimination of such a common problem as the misalignment of the wheels on the hub after careless installation, which as a result contributes to the destruction of the hub bearings, steering rod joints, which, of course, affects the movement of the crane installation. It has a ventilation and heating system, sound and thermal insulation, and is equipped with a hydraulic lift.

To ensure safety during work MKT-25.1 has all the necessary complex of devices and mechanisms. Thus, if it is necessary to work in cramped conditions, if there is a risk of damaging the boom, the operator at the beginning of work can set the limit angles of rotation of the MKT-25.1 crane installation. For example, on the one hand, the rotation of the crane is limited by the corner of the building, on the other hand, by a high lighting column. Next, limit the maximum outreach of the load from the axis of the slewing device of the truck crane, and when working on a truck crane with outriggers, set the limit overturning moment. These operations are carried out in a matter of minutes, after which the operator can do the work. Competent automation is designed in such a way that when approaching the set parameters, it automatically warns the operator about this (by sound and flashing the button on the display), and in critical situations it will block the control. Moreover, a modern truck crane of this model is equipped with a device without which it is forbidden to work. It's about about a mechanism that does not allow a dangerous supply of an arrow to power lines. If you decide to buy an MKT-25.1 truck crane, then you should pay special attention to the above characteristics.
