The DEK-401 crawler diesel-electric crane with a lifting capacity of 40 tons is designed for loading and unloading, construction and installation work. The crane is equipped with a 15 m main boom, which can be extended with 5 m extensions up to 35 m using threadless pin connections for quick assembly. It is possible to install a fixed jib with a length of 5 or 10 m, and tower-boom equipment with a jib length of up to 20 m.
The use of thyristor electric drives for all crane mechanisms allows for smooth and accurate crane operations. An intelligent control system allows you to obtain unique functions, for example, “height stabilization” - moving cargo at a fixed height due to the simultaneous operation of the boom and cargo winches.
The crane cabin is heat and sound insulated using modern materials. The large glass area of the cabin provides good visibility of the working area and cargo winches. A chair with numerous adjustments, hydraulic shock absorption, pneumatic support for the backrest and a headrest helps create maximum comfort for the operator.
The width-adjustable crawler track (4400 mm in working position and 3200 mm in transport position) allows the crane to be transported on a trailer along public roads without violating the transport dimensions.
The DEK-401 crane is powered both from its own 90 kW diesel generator and from an external three-phase alternating current network with a voltage of 380 V.
Self-installation and transportation of DEK-401 crane
The DEK-401 crane is functionally independent from other lifting equipment: the crane independently unloads from the platform and mounts boom equipment, i.e. is actually self-mounting.
To move it to the working position and back, the crane is equipped with a hydraulic system for spreading beams and outriggers. The width-folding crawler track and portal provide compact transport dimensions. During transportation, the cabin and track beams are not dismantled, which speeds up the commissioning of the crane.
On paved roads the crane can be transported using a standard trailer without disassembly. Over short distances, including within the construction site, the crane can move under its own power at a speed of 1 km/h.

A winch is used to move the load on the crane. The winch includes a drum, a drive mechanism, intermediate gears, a braking device and a support frame (frame). The cargo winch crane is driven by two electric motors: 5 kW and 30 kW. The first electric motor is connected to a single-stage gearbox by a clutch with a brake disc. The brake is equipped with a hydraulic pusher TKTG-200*. The second electric motor is connected to a second two-stage gearbox by a clutch with a brake disc. The first and second gearboxes are connected to each other using a differential installed in the housing of the second gearbox. A drum is attached to the output shaft of the gearbox. The winch is multi-speed and the following options for its operation are possible: the second engine is braked, the first engine is running; the first engine is braked, the second engine is running; both engines operate, rotating in the same direction; Both engines work, rotating in different directions. From this it can be seen that each case of winch operation provides a different speed of lifting or lowering the load (depending on the direction of rotation of the engines) and that by appropriate selection of gear ratios, you can obtain any drum rotation frequency and even a frequency equal to zero, or change its direction movements. The SKG-40A crane uses a jib winch of an original layout: the drum is located under the electric motor, which, in turn, caused the creation of a vertical multi-connector gearbox design.

The design of the slewing bearing with an individual drive is made in the form of a double-row thrust ball bearing consisting of three rings. The crane has a differential-free movement mechanism, which is driven by two 22 kW electric motors. Each track has an individual drive: both movement mechanisms are mounted on the running frame between the tracks. The mechanism consists of a motor, brake, gearbox, cardan shafts and an elastic coupling. Cardan shafts are telescopic, gearboxes are two-stage and single-stage. The running device includes a beam and two crawler tracks. The crawler carriage consists of longitudinal beams, drive wheels, support rollers, tension (guide) wheels, support rollers and a caterpillar chain. The caterpillar chain consists of individual links - tracks, which are connected to each other by pins. Link tracks have projections called ridges. The profile of the ridge matches the profile of the drive wheel. When the drive wheel rotates, the drive mechanism of the movement - the caterpillar chain - begins to roll around it, but visually the lower branch of the chain remains motionless, and the running frame, together with the slewing ring and the entire crane on the support rollers, rolls along the lower branch, as if on a track; in this case, the ridges on the inside of the tracks serve as guides. The support rollers have recesses corresponding to the profile of the ridge. The drive wheel is installed on the tail of the crawler to provide tension on the lower branch of the crawler chain, and this in turn contributes to a more even distribution of the crane's pressure on the ground.

Scheme of lever-type hook lift height limiter
The SKG-40A crawler crane uses a multi-engine diesel-electric AC drive. The power plant DG-75-3 of the crane consists of a 64НЧ12/14 diesel engine and an EC-93-4S generator with a power of 75 kW. All motors of the actuators receive power from their own generator, through an external power supply with a voltage of 380 V through a ring pantograph. The main hoist winch is equipped with a crane motor with a phase rotor controlled by a controller and a squirrel-cage motor, which is turned on and off using a starter. The auxiliary lift winch is equipped with a two-speed squirrel-cage motor controlled by a controller with modified cams. The boom winch has a squirrel-cage motor controlled by a cam controller. The swing mechanism is equipped with a crane motor with a phase rotor. The electric motor is controlled using a cam controller. Each movement mechanism is equipped with a phase motor controlled by a cam controller. The circuits of the main motors and the entire crane have current protection in the form of overcurrent relays. When the tap is powered from an external circuit, the current flows through the flexible cable KRPT-3x35+1x10 into the input box and then to the pantograph. To connect the cable when loading the crane onto a railway platform, there are terminals mounted at the switch-disconnector. The switch is used to connect the power circuit of the crane with the generator circuit when operating from a diesel engine or an external circuit. In the general circuit, as well as in the circuits of the auxiliary lift and boom winches, automatic switches are provided, mounted on the control panel. A voltmeter, ammeter and frequency meter are also installed there. For safe operation, limiters of working movements and load capacity are used, the limit switches of which are included in the control circuit (on the SKG-40A and SKG-63A
a lever-type hook lift height limiter is used). There is also a general emergency switch, which allows the driver, if necessary, to de-energize the entire crane, and a hatch switch for lowering into the running frame, which turns off all crane mechanisms. The alarm and lighting networks are included in the power circuit through a 380/12 V transformer with a power of 0.25 kW. The transformer supplies current to four light bulbs to illuminate the cabin and to the light bulb on the control panel; An audio signal is included in this circuit. To illuminate the external area, two spotlights with lamps with a power of 500 W and a voltage of 220 V are installed. For repair lighting, a portable 12 V lamp is used, which is powered by two 6-STE-128 batteries. The batteries power the internal lighting network when the tap is de-energized. The batteries are connected using a package switch. The control circuit is connected directly to the power circuit of the crane through fuses. A PZKB-160 protective panel is mounted in the control cabin. To heat the control cabin in winter, an electric furnace with a power of 1 kW and a voltage of 220 V is installed.

Work related to lifting multi-ton cargo in various sectors of production, construction, public utilities and private services requires the use of crane equipment. Such equipment must be reliable and trouble-free. A worthy example is the DEK-401 crawler crane. The Chelyabinsk forty-ton truck was thoroughly thought out by engineers down to the smallest detail. This gives him the opportunity to successfully compete in domestic and foreign markets.
Crawler crane DEK-401
The DEK crawler crane is designed for the installation of large structures and is used in residential construction, in the design of industrial facilities, and in the construction of bridges and highways.
DEK-401 has been produced by the Chelyabinsk Mechanical Plant (ChMZ) since 2009. As soon as the crawler crane leaves the assembly line, it is awarded the “100 Best Products of Russia” award. Distinctive features that set it apart from previous models are primarily the electronic control of operations and the addition of a new membrane boom. The development of the device for this boom was patented by ChMZ; it is more reliable - the rigidity of the boom during bending and torsion has increased. The main boom is 15 meters long, if necessary, and can be extended with five-meter inserts to a maximum length of 35 meters.
The DEK-401 crawler crane does not depend on other lifting equipment; it is completely self-erecting. Among the advantages, it is also worth mentioning the versatility of the crane - it works both autonomously - from its own D-246 engine, and from the network (380 volts, 50 Hz).
Description of the DEK-401 crane
The tracked DEK-401 is multifunctional and reliable - despite its fairly compact dimensions:
- original (non-working) length, m – 12.352;
- width in working position, m – 4.4;
- initial (non-working) height, m – 3.2;
- track width of DEK-401 tracks in working position is 4.4 m, length – 7537 mm
The crane is extremely resistant to overturning. The platform rotation mechanism is highly durable and durable.
With the weight of the crane itself in working position (with the main boom) being 55t, its nominal lifting capacity is 40t.
The portal of the DEK-401 crawler crane uses two independent racks, which provokes an even distribution of the load on all load-bearing elements.
The high level of noise and heat insulation of the cabin makes the operator's work easier. All manipulations are performed using two joysticks. Operational safety is controlled by a microprocessor-based load limiter.
The high level of design developments and quality of execution of the DEK-401 crawler crane make it a leader in its equipment segment.

Description
The DEK-401 crawler crane is an innovation in the world of lifting equipment that has proven itself to be the best in a very short time. The reasons lie in its simple assembly, efficiency, and versatility. We invite you to study the characteristics of DEK-401 in more detail. From us you can purchase tracked vehicles on optimal terms.
Features of design and operation
The crane, which lifts loads up to 40 tons, is designed not only for this - its diesel power station is used as a power source in the economy and other industries. But this is only one of its features.
Manufacturers of DEK 401 equip their crawler cranes with membrane-type booms. The technology was developed by them and patented. This solution made the boom stronger when operating at maximum conditions, and also increased its rigidity under torsional and bending loads.
The design of the DEC 401 crane uses imported elements. An example is a slewing bearing from the Slovak company PSL. It reduces the resistance of the machine when the platform rotates, minimizing the risk of tipping over. Loads can move parallel to the support when the boom length changes. This is accomplished by means of an adjustable throttle electric drive from Siemens.
The Deck 401 crawler crane, along with other Chelyabinets models, has a comfortable operator cabin. Wide glass area, noise and heat insulation, microprocessor controller of operating parameters, ergonomics of the control panel are just some of its features.
The diesel-electric installation DEK-401 is located away from the operator's cabin. The consequence of this is a minimum of cabin vibrations and reduced driver fatigue.
The length of the basic boom is 15 m; when equipped with 5-meter inserts, it can be extended to 35 m. The boom also allows you to install a fixed or shunting jib (up to 20 m long).
If the deck crane 401 will operate in winter or in the Far North, it is equipped with a pre-heater.
DEK-401: technical characteristics
The main parameters of lifting equipment are given below:
- maximum load capacity on a fixed jib - 6.5 tons; on a shunter - 11 tons;
- maximum lifting height - 49 m;
- speed of lifting/lowering the load - up to 10 m/min;
- travel speed - 1 km/h;
- turning radius - 4.65 m;
- platform rotation speed - up to 1 rpm;
