The KS-55713-1K-3 truck crane with a lifting capacity of 25 tons is mounted on a KamAZ-65115 chassis. The truck crane is designed for loading and unloading, construction and installation work at dispersed sites. The chassis has good maneuverability, which allows the crane to be used at sites with various types of access roads, and its small dimensions make it suitable for operation in the cramped conditions of modern cities.
The crane installation is driven by two axial piston hydraulic pumps, which are driven into rotation by the base chassis engine. The crane mechanisms have an individual drive with independent control from hydraulic motors and hydraulic cylinders. The crane's hydraulic system provides smooth control of all mechanisms with a wide range of speed control for working operations, as well as the ability to simultaneously combine several crane operations.
The four-section telescopic boom, made of high-strength steel, has a length of 9.5 - 28.0 m. In the retracted position, the boom provides the truck crane with high maneuverability, and in the extended position, it provides a wide working area. Additional equipment of the boom in single file increases the size of the under-boom space. The transfer of the jib from the transport position to the working position and back is done manually without the use of additional lifting equipment.
The ability to telescope the boom with a load on the hook allows the truck crane to install loads in hard-to-reach places and carry them among mounted structures. For the convenience of working in cramped conditions, a load handling mode is provided with the crane installed on supports with the outrigger beams retracted.
The safe operation of the KS-55713 truck crane is ensured by a load limiter with a digital indication of operating parameters. The device automatically protects the crane from overload and capsizing, is equipped with a coordinate protection system necessary for working in cramped conditions, has a built-in telemetric memory unit and a hazardous voltage protection module for working near power lines.

KS-55713-1K-3
The KS-55713-1K-3 automobile jib crane with a lifting capacity of 25 tons is mounted on the chassis of a KamAZ-65115 vehicle. Designed for loading and unloading and construction and installation work at dispersed sites. The chassis has excellent maneuverability and ease of control, which allows the crane to be used on sites with various types of access roads, and its small dimensions make it suitable for operation in the cramped conditions of modern cities.
Actuator drive
The crane installation is driven by an axial piston hydraulic pump, which is driven by the engine of the base vehicle through a gearbox and an additional power take-off. The crane mechanisms have an individual drive with independent control from hydraulic motors and hydraulic cylinders. The hydraulic system of the crane installation ensures smooth control of all mechanisms with a wide range of speed control for working operations, as well as the ability to simultaneously combine several crane operations. The gearboxes of the mechanisms for lifting loads and turning the crane are planetary type with disc brakes, which meets modern requirements for lifting machines. Many crane components use imported components that do not require replacement or repair over the entire service life of the crane. An autonomous diesel heater is used to heat the cabin.
Boom and telescoping system
The four-section telescopic boom is made of high-strength steel. The boom sections are made of two bent all-metal profiles in accordance with modern trends in global crane construction. Optionally, it is possible to install an OVoid boom. Together with a fundamentally new system for telescoping boom sections, all this made it possible to significantly reduce the total mass of the boom, while increasing its strength and load-height characteristics. The length of the boom in the retracted position is 9.5 m, which makes the crane compact and maneuverable when moving. When all four sections are fully extended, the length of the boom is 28 m, which provides a large working area and the greatest height of load movement during operation. The ability to telescope a boom with a load on a hook allows the crane to perform special tasks: installing loads in hard-to-reach places, carrying them among mounted structures. For the convenience of working in cramped conditions, a mode for working with loads is provided with the installation of the crane on supports with the outrigger beams retracted.
Additional equipment expands the range of possibilities
Additional equipment of the boom with a lattice jib 9 m long allows for the largest service area and the size of the under-boom space. The transfer of the jib from the transport position to the working position and back is done manually without the use of additional lifting equipment.
Functionality and performance
Due to the large size of the support contour (5.0 x 6.1!!!), the crane can carry out work with loads in a 360° circular zone, which allows minimizing the number of rearrangements when working on site. Thus, the functionality and performance of this crane model on work sites significantly exceeds that of existing analogues.
Truck crane reliability
Reliable operation of the truck crane is ensured by foreign-made components that do not require replacement or repair during the entire service life of the crane.
Truck crane safety
Safe operation of the crane is ensured by a complex of instruments and devices, including a microprocessor load limiter with digital indication of operating parameters on the display in the driver’s cabin. The device automatically protects the crane from overload and capsizing, is equipped with a crane coordinate protection system necessary for working in cramped conditions, has a built-in telemetric memory unit (“black box”) and a crane protection module from dangerous voltage (MZON) for working near power lines.
Convenient crane operator workplace
The truck crane is equipped with a crane operator's cabin that meets the latest requirements for comfort and visibility: a compartment-type sliding door, a diesel heater, a fan, a folding rear hatch, and a convenient instrument panel. Convenience of control of crane operations is achieved due to the original arrangement of control levers.

Design and characteristics of the KS-55713-1K-3 truck crane
Purpose of the KS-55713-1K-3 truck crane The KS-55713-1K Klintsy truck crane with a lifting capacity of 25 tons on the Kamaz-65115-62 truck chassis is used to perform loading and unloading, construction and installation operations in industry, construction, agriculture and others industries (work with simple loads). The KS-55713-1K-3 truck crane is designed for operation at an ambient temperature of ±40°C and a relative humidity of 80% at +20°C and storage at an ambient temperature of at least -50°C. Transport movement of the KS-55713-1K-3 truck crane between work sites is recommended on hard-surface roads that allow an axial load of at least 10 t. Installation of the Klintsy truck crane is possible on a prepared site with dimensions of 6.0x6.5 m and a slope of no more than 3°. The permissible wind speed for the operating position of the crane should not be more than 14 m/s at a height of 10 m, for the non-operating state - 3-40 m/s. Composition and structure of the KS-55713 truck crane The KS-55713-1K-3 Klintsy truck crane with a lifting capacity of 25 tons based on the Kamaz-65115 chassis (Fig. 1) consists of load-bearing welded metal structures, mechanical and hydraulic units (units), which are structurally combined into three main parts: fixed part of the crane 1; rotary part of the crane 2; working equipment 3.
Rice. 1. KS-55713 automobile jib crane 1–fixed part: 1a-support frame; 1b - retractable support; 1c-rotating support; 1g - KamAZ-65115-62 chassis; 1d-hydraulic tank; 1st boom support stand; 1z-facing; 1st-stump equipment; 1k pump drive. 2-rotary part: 2a-cabin; 2b-cargo winch; 2v-frame rotating; 2G crane control drive; 2D fuel supply drive; 2e-casing. 3-working equipment: 3a-boom lifting mechanism; 3b-telescopic boom; 3v-hook suspension; 3g-load rope. The non-rotating part of the KS-55713 truck crane includes: KamAZ-65115-62 chassis, support frame with retractable supports, rotating support, boom support stand, cladding, pump drive, pneumatic equipment, retractable support control, hydraulic tank, spare wheel mounting bracket 1. Rotating part truck crane is attached to a rotary support. It consists of: a rotating frame, a cargo winch, a turning mechanism, a cabin, a heater, crane control drives, engine control, and a casing. The working equipment of the KS-55713-1K-3 Klintsy 25t truck crane based on KamAZ-65115 consists of a three-section telescopic boom, mechanisms for lifting and extending the boom section, a cargo rope and a main hook suspension for 8 and 6 fold reeving. In order to increase the lifting height and under-jib space, the crane design provides for the possibility of installing a jib with a length of 7.5 m on a telescopic boom. In this case, the reeving of the cargo rope must be one-time, and the main hook suspension must be replaced with an additional hook suspension. Changing the angle of inclination of the telescopic boom of the crane is carried out by a mechanism for changing the reach, and the extension of sections is carried out by a mechanism for extending the boom. The telescopic boom is attached to the racks of the rotating frame using an axle. The cargo rope is fixed to the winch drum. The mechanisms and hydraulic equipment located on the rotating frame are covered with a casing.
The load-handling device on the KS-55713-1K Klintsy truck crane with a lifting capacity of 25 tons on the Kamaz-65115 truck chassis is a hook suspension. Raising and lowering the load is carried out by a lifting mechanism. The connection between the rotating part of the crane and the non-rotating part is carried out by a rotating support (slewing support). The rotation of the rotating part of the crane is carried out by a turning mechanism. The telescopic boom allows the KS-55713 truck crane in the transport position to have speeds and maneuverability close to the base KamAZ-65115-62 chassis. Elements of hydraulic equipment and electrical equipment are located on the fixed and rotating parts of the crane and on the working equipment.
Fig.2. Cabin 1 - controls for crane operations; 2-instrument panel; 3-light; 4-sun visor; 5-seat.
The truck crane is equipped with safety devices. To monitor the condition of the crane and its components, as well as to control the crane, instrumentation and controls are used (Fig. 2).
The controls for the crane's actuators are located in the crane operator's cabin.
The speed of crane operations depends on the position of the actuator control handles: the further the handles are deviated from the neutral position, the higher the speed of a particular operation. The hydraulic circuit of the Klintsy 25t truck crane based on KamAZ-65115 also provides for the possibility of obtaining increased speeds of cargo movement. Operation of the KS-55713 truck crane The operation of all crane mechanisms is carried out from the chassis engine. The power taken from the engine through the pump drive through the working fluid of the hydraulic system is transmitted to the actuators and hydraulic cylinders of the crane through ballasts. Truck crane KS-55713 Klintsy 25t based on KamAZ-65115 the following operations: - hanging the crane on retractable supports; — raising and lowering the telescopic boom; — turning the rotating part of the crane; — lifting and lowering the load with a winch; — telescoping of the boom section; — removing the crane from the retractable supports; Using the crane operations control drive, the chassis engine control drive and the hydraulic equipment ballasts, you can regulate the speeds of the mechanisms performing basic crane operations. It is possible to combine any two crane operations with loads equal to 50-60% of the rated load capacity for a given load characteristic.
