Technical characteristics of the lifting device of the crane KS-45719
The hydraulic drive of the KS-45719 truck crane operates from 2 hydraulic pumps. They are connected by a power take-off from the car chassis. PTO performance can be adjusted depending on the load. Power take-off and torque from the engine are carried out through the transmission box. The potential and characteristics of the transmission are fully optimized for engine performance (applies to all chassis options). The lifting mechanism has autonomous control, providing individual drive, as well as hydraulic motors and hydraulic cylinders. Working manipulations on the KS-45719 truck crane can be combined to increase labor efficiency and productivity.
By installing smoothly controlled hydraulics, the efficiency of using crane devices and outriggers increases. In this case, the load can be changed by selecting certain gearbox speeds and thus selecting a suitable operating range of engine speeds.
The KS-45719 crane has a telescopic boom consisting of three sections. Possible boom lengths are in the range of 9.7 - 21.7 meters. In the transport position, the KS-45719 truck crane can be made quite compact, which significantly improves maneuverability when the crane moves along city streets.
KS-45719 is a universal truck crane that has many mechanisms for more convenient and efficient work. In particular, in addition to the large support contour, it is worth highlighting the high-tech design of the boom. Its main feature is the telescoping system, which includes a pair of extension hydraulic cylinders. This makes it easier to control the process of extending or retracting each of the moving sections. Thanks to the telescoping boom of the KS-45719 truck crane with a load on a hook, you can move loads in hard-to-reach places without touching existing structures that are located nearby.
The KS-45719 truck crane uses the ONK-140 module. This microprocessor-based load limiting system is one of the crane's highest safety features. This system monitors the condition of all instrumentation, devices and moving elements of the KS-45719 truck crane. For a more visual and convenient monitoring of the status of these devices, an electronic indication is provided, as well as sound signals that are triggered when problems are automatically detected. The instrument panel with indication is located directly in the driver’s cab. Also included in the package is the so-called MZON, which protects the truck crane from dangerous voltage - for example, if you have to work near power lines.
The KS-45719 truck crane has an integrated system that protects against rollover and overload. Automatic activation of sound and light alarms is triggered if necessary, when it is necessary to notify the operator of a violation of safety regulations.
KS-45719 is a modern truck crane equipped with a so-called telemetric “black box”, which records the entire process of the crane’s working operations. The “black box” operates throughout its entire service life.
The KS-45719 truck crane model has a main set of sensors that are responsible for the following functions:
- monitor the angle of lift of the boom, as well as the length to which the boom is extended;
- control the maximum permissible load capacity;
- determine the lifting height of the hook suspension;
- determine the degree of tension of the cargo rope;
- signal an undesirable approach to power lines.
Modifications of the KS-45719 truck crane
KS-45719 truck cranes were produced at the Galichansky and Klintsovsky truck crane plants, and during the entire production period many modifications were assembled, which differ in chassis characteristics. Let's look at the most popular models of the KS-45719 truck crane and outline their technical characteristics.
KS-45719-1 “Galician”
The KS-45719-1 “Galichanin” truck crane with a maximum lifting capacity of 20 tons is installed on a KamAZ-53215 truck chassis with a 6x4 wheel arrangement. Its easy-to-operate and reliable configuration has made this model of truck crane in demand for a wide range of construction, installation and loading operations.
The KS-45719-1 truck crane is equipped with retractable hydraulic outriggers. The maximum size of the support contour with full extension of the legs is 5.25 x 5.8 m. This contour is achieved through the use of an outrigger design with folding support beams. With this design, the crane is able to carry out work with loads in a 360-degree circular zone and, as a result, the number of rearrangements of the KS-45719-1 truck crane when working on site is reduced.
Due to the enlarged support contour, the KS-45719-1 truck crane is also provided with excellent stability when working with loads at medium and long ranges. The large support contour allows for better lifting characteristics than truck cranes with a lifting capacity of 25 tons. For ease of control in cramped conditions, the crane has a mode for working with loads with installation on supports with the outrigger beams retracted.

___________________________________________________________________________
The KC-4571 truck crane with a lifting capacity of 16 tons is designed for loading and unloading, construction and installation work at dispersed sites. It is mounted on the chassis of a KrAZ-257K vehicle and has an individual hydraulic drive mechanism.
The fixed part of the crane, mounted on the chassis of the base vehicle, contains: a hydraulic pump drive, a lower frame of the crane with hydraulically driven outriggers, a spring locking mechanism, an inclinometer, an oil tank, a central manifold and pneumatic equipment. The rotating part of the KS-4571 crane is installed on a roller slewing bearing. It is equipped with mechanisms for lifting loads and turning, and on the racks there is a telescopic three-section beam boom, on which a jib 6 m long can be attached. The length of the boom can vary from 9.75 to 21.75 m. The crane mechanisms are driven from the vehicle engine through gearbox, transfer case and power take-off.
From the power take-off, rotation is transmitted through the cardan shaft to the pump drive gearbox, from which the working fluid under pressure is supplied to the crane mechanisms. The drive ensures the combination of the following operations: lifting (lowering) the load with rotating the platform; extension (retraction) of boom sections with raising or lowering of the boom; extension (retraction) of boom sections with rotation of the platform. The KS-4571 truck crane is equipped with safety devices: OGB-3 load limiter, boom outreach and load capacity indicator, UNSh-1 inclinometer, ASON-1 device for warning, alarm when working near high-voltage power lines, emergency engine stop handle, signaling devices. The crane can move with a load on a hook weighing 6 tons with a boom length of 9.75 m with an outreach of 3 m and the boom position “backwards”. Hydraulic outriggers install within 2 minutes with ground control and no manual operations. Support frame of the KS-4571 truck crane The support frame is installed on the chassis of the base vehicle (chassis side members) and transfers the loads acting on the crane to it. The support frame houses the slewing ring, outriggers and suspension switches or stabilizers. The longitudinal beams of the support frame (Fig. 1) have a rectangular cross-section and are connected to each other by transverse beams. The beams are made of sheet or shaped steel.
A support ring is welded to the longitudinal and transverse beams, onto which the crane's slewing ring is bolted. The ring rests on struts welded to the sides of the beams, which provide it with the rigidity necessary for normal operation of the slewing bearing. In the necessary places, brackets are welded to the frame, to which the crane equipment is attached: stabilizers, spare wheel bracket, etc. Front and rear beams are welded at the ends of the frame, on which outriggers are installed. Rice. 1. Support (lower) frame of the KS-4571 truck crane assembly 1 – hydraulic cylinder; 2, 6 – front and rear outriggers; 3 — metal structure of the support frame; 4 — support ring of the slewing bearing; 5 - stabilizer; 7 - nut; 8 — overlay; 9 - stepladder.
