Truck crane "Chelyabinets" KS-55732-33 Ural-NEXT 4320 (25 t.)

KS 55732 Chelyabinets is a Russian-made crane installation used in the construction and rescue industry. This device has high potential and is designed to work in hard-to-reach conditions. High maneuverability and advanced functionality allow the KS55732 to be used in installation and construction operations, moving cargo over long distances at air temperatures from minus 40 to +40 degrees. Excellent adaptation to harsh Russian conditions, as well as a powerful heating system and sound insulation allow this truck crane to be used in Siberia. High productivity and rich technical equipment are the inherent advantages of KS 55732 Chelyabinets.

Description and purpose

The truck crane of the same name was developed on the latest generation KamAZ truck chassis with a Euro-4 engine. Using this crane installation, you can perform loading and unloading, construction and installation work - both in construction and industrial fields, as well as in agriculture. The equipment is designed to work with any load, and is capable of moving at a speed of 60 km/h thanks to good accelerating aerodynamics. In addition, the KS 55732 model has proven itself well in work in logistics centers. In addition, a truck crane based on a KamAZ chassis will be a successful replacement for low-power manipulators. Moreover, the model in question is in demand among the emergency services of the Ministry of Emergency Situations for dismantling and removing rubble.

Competitive advantages of Ural-NEXT vehicles
Automobile cranes KS-55732 with a lifting capacity of 25 tons “Chelyabinets” have the following set of advantageous characteristics:

1. The multifaceted bent profile of the boom sections using high-strength steel makes it possible to reduce the weight of the boom, which, along with the support contour, is 5.75x6.0 m. provides excellent stability of the crane, and as a result, greater lifting capacity at medium and long reach (maximum boom length 33.0 m, lifting height – 32.9 m).

2. The ability to move heavy loads among already assembled structures due to the large possible mass of the telescopic load (the mass of the telescopic load is 6 tons).

3. The high traction force of the winch allows you to lift the maximum load with a 6-fold reeving of the cargo rope, which ensures a high speed of lifting and lowering the load, reducing the time for feeding the hook for slinging the load, low maintenance costs for pulley blocks, and work on laying pipes in a deep trench and back.

4. The low weight of the crane installation ensured optimal loads on the chassis axles to meet regulatory requirements for weight control, efficient fuel consumption and an increased service life of the chassis elements.

5. High level of comfort in the crane operator’s cabin, meeting the requirements for railway clearance (when transporting the crane on a railway platform, dismantling the cabin is not required). The built-in control panel and air ducts for blowing the windshield and side windows provide excellent functionality and an optimal microclimate in the cabin. Quick heating of the cabin in winter is ensured by an economical heater with low noise levels.

6. Increased ergonomics of the crane operator’s workplace, due to the use of side control levers for crane operations, ensuring ease of control, reducing operator fatigue, and increasing the productivity of work performed.

7. Highly informative color graphic 7″ display of the display unit with touch control (with the ability to work with gloves) does not require preheating the cabin at low temperatures. Tempered glass is resistant to mechanical damage. The display unit's sun visor protects the display from glare. Analogue sensors have been eliminated, now information about all readings (pressure in the engine lubrication system, coolant temperature, oil temperature in the crane hydraulic system, crane leveling) is displayed on the display of the safety device, and information about the operation of the crane can be retrieved using a USB flash drive.

8. Extended testing program for truck cranes.

9. Possibility of equipping with additional options depending on climatic conditions, types of work, loads, as well as other operating conditions.

Features of the device and operation

KS-55732 entered production in 2012. The machine is equipped with a telescopic 28-meter boom, which provides enormous capabilities when moving cargo over long distances. This model is improved in all respects compared to its predecessor, which had a boom height of 21.7 meters. It was possible to increase the length very simply by adding an additional section. In terms of design, the model is similar to KS-45721. In addition, the “calling card” is the bright white color, familiar from the Chelyabinets family of truck cranes of recent generations.

The powerful 300-horsepower engine of the truck crane is capable of pulling large and heavy loads, regardless of the location of the crane - on a mountain, off-road or in muddy mud. The truck crane cabin is equipped with an autonomous heater, pre-heater, heated mirrors, and a multifunctional steering wheel with reach and lift height adjustment. In addition, the driver's seat itself is mounted on an air spring. According to modern technical norms and standards, the cabin is equipped with two seats, between which there is a lot of free space. A sleeping place is available as an option.

KS-55732 is equipped with permanent all-wheel drive with inter-axle and inter-wheel locks in the rear wheels. Maximum fuel consumption is 50 l/100 km at speeds of 60 km/h. In crane operating mode, the power unit consumes only 10 liters per hour. Despite acceptable fuel efficiency, the car received a fuel tank with a volume of 210 liters, which significantly affected the increase in driving range.

The chassis is equipped with a heated fuel intake, a fuel filtration system, and the “pomatronic 4D-24” device is responsible for pre-heating the engine.

The four-section boom, 28 meters long, is made of high-strength alloy with a bent profile, and also has a welded seam along the side of the boom. Due to this arrangement, it was possible to reduce the weight of the boom and the total weight of the truck crane, and thereby increase maneuverability and efficiency. Each boom section can extend simultaneously with the others, under the influence of a powerful hydraulic cylinder. In this case, the extension occurs to the desired length. The working pressure of the hydraulic cylinder is 25 MPa.

Please note that the productivity of the boom during telescoping can reach 6 tons. In addition, it is possible to work in a 360-degree zone due to the crane’s outstanding long-range lifting characteristics.

The KS-55732 truck crane installation uses a ball bearing and slewing device. It has externally geared teeth, 40 mounting holes, and four oil channels that are responsible for the effective lubrication of rollers and raceways.

The high performance of the hydraulic system allows up to two working operations to be carried out simultaneously. The capacity of the reservoir required for efficient operation of the hydraulic system is 560 liters. To clean consumables from mechanical impurities that inevitably appear during natural wear of parts, the oil tank is equipped with a drain filter.

Model KS-55732 is made mainly from domestic components, but some components are borrowed from foreign partners.

Let's highlight a few of them:

• Crane cabin
• Planetary cargo winch
• 4-section hydraulic distributor (model HC-D16/4)
• 5-section hydraulic valve (model HC-D4/5)
• Two way crane installation
• Slewing ring
• Multilayer seals in the hydraulic cylinder.
