We are sure that construction cannot be done without special machines, which can safely include KS 45717 1 truck crane installed on a KamAZ 4320 vehicle (6 x 6). The capabilities of the model, its purpose, and technical characteristics will be discussed.
Let's consider the options for purchasing and renting, and find out how much the service can cost. One thing is certain, we can say that production processes on construction sites would be much more difficult without a “one-armed assistant.” Let's get to know him.
The main purpose of the design
Such characteristics of the crane as full rotation, hydraulic drive and rigid attachment of the telescopic boom make it possible to automate loading and unloading operations.
In addition, it can be used to carry out installation and construction work. The advantage of this technique is that it can be used at dispersed sites.
Thanks to installation on a vehicle chassis, the crane can be moved on roads with any surface.
The design of the model allows it to be used in a temperature range from -40 to +40 degrees.
At temperatures below -50 degrees, the tap can only be inoperative:
- in the temperature range from -40 to -50 degrees - in an open area;
- at a level of less than -50 degrees - indoors.
There are also conditions for safe operation of the device (measurements are carried out at a height of 10 m):
- wind speed should be up to 40 m/sec;
- in operating mode – up to 14 m/sec;
- the working platform can deviate by no more than 5%;
- in the case of using outriggers, the angle of inclination of the crane to the horizon is no more than 1.5 degrees.
The KS-45717k-1 truck crane is a full-rotation hydraulically driven crane with a rigid telescopic boom suspension on a MAZ vehicle chassis and is designed for mechanization of loading and unloading and installation and construction work with conventional cargo, as well as toxic and explosive substances at dispersed sites. The movement of an automobile jib crane between work sites is provided for on all types of roads. Operation of the KS-45717-1 truck crane based on MAZ is allowed in areas with a temperate climate in the temperature range from minus 40 °C to plus 40 °C.

Operating Parameters
The Ivanovets KS-45717-1 truck crane is of the jib type. The through rod for lifting loads has a three-section structure and a telescopic structure.
If necessary, upon special order, the kit can be supplemented with extension equipment - a 7 m single file.
Find out the types and technical characteristics of tower cranes, without which not a single large-scale construction project can be completed. This review discusses the features of using self-propelled scissor lifts.
The model has a number of carrying capacity characteristics. The crane's capabilities vary depending on the conditions.
When working on extended supports with a boom length of 9 m and a reach of 3 m, the maximum lifting capacity is 25 t for simple cargo and 20 t for explosive and toxic objects.
With retracted structural elements to transfer the load from the device to the surface, this figure will be 6.3 tons. With extended supports and a boom 21 m long with a reach of 8 m, you can operate with a weight of 1.95 tons.
If it is necessary to extend additional sections, the mass held by the crane should not exceed 0.3 tons.
The maximum load moment for a crane with a boom length of 9 m is 735 (75) kNm (tf•m). With a length of 21 m with a jib – 153 (15.6) kNm (tf•m).
The maximum lifting level with a conventional boom up to 21 m reaches 21.3 m, with the longest length with a jib - 28.2 m. At the minimum length, the lowering depth will be 15 m.
How it works
The unit is divided into two large parts:
- rotary,
- non-rotating.
The first group includes the chassis, frame, four outriggers, pump drive, device for supporting the vertical shaft axis, boom stand, lining and an additional wheel.
All these elements are made of high-quality materials, since the service life of the crane depends on their reliability.
The second group includes support, counterweight, lifting systems, changes in reach, rotation, existing and replaceable operating equipment.
In addition, the structural elements of the crane include hydraulic drive and electrical equipment. These elements are responsible for the functionality of the model. This also includes control drives.
An important factor is the availability of a set of spare parts, tools and other necessary accessories.
The two main parts of the crane structure are connected to each other by a slewing support system.
Those elements of the mechanism that are located on the platform are securely covered with a casing. This can protect important components of the crane from mechanical damage and harmful effects of the external environment.
There is a PTO on the chassis gearbox. With its help, torque is transmitted to the pump. This process leads to power supply to the working mechanisms, which have an individual hydraulic drive.
Among the advantages of the crane are autonomous and joint operation of components. A long-stroke hydraulic cylinder and quantum pulleys are used to extend the boom. With their help, the outer sections are advanced or retracted.
Control Features
The main controls are located in three places: in the driver's and crane operator's cabins and on the crossbar behind the support frame. There are also control and measuring equipment there.
The driver's cabin contains those control systems that are responsible for the chassis and partly for the crane.
Here are:
- time counter;
- hydraulic system filter clogging indicator;
- PTO operation signal LED;
- chassis motor switch panel;
- fuse for electrical equipment of crane installation;
- release lever lock;
- starting the hydraulic system pump drive.
The crane operator's cabin also includes control levers. The fuel control pedal located among them can be in three positions.
The lowest of them involves rapid rotation of the engine crankshaft. To achieve the optimal performance between 900 and 1,100 rpm, you must keep the pedal in the down position. For idle speed, select the highest level.
There is also a lever here that changes the length of the arrow. Extension occurs by moving the handle forward, and retraction occurs by tilting it back.
The turntable control lever is located nearby. It has a beep button. Moving the lever forward will cause the platform to rotate to the right, pulling it back will cause it to rotate to the left.
The next handle controls the movement of the hook. It contains a button for accelerating lowering or raising. The angle at which the boom is positioned is controlled using another knob. Due to its movement, you can increase or decrease the reach.
Do you know the technical characteristics of truck cranes with a lifting capacity of 25 tons, which are the most popular? This information: https://spez-tech.com/tehnika/gruzovie-avto/zil/130-harakteristiki-i-osobennosti-konstruktsii.html will allow you to understand the features of equipping the ZIL-130 with additional equipment.
And here the technical characteristics of the overhead crane are discussed and the procedure for its installation is described in detail.
The instrument panel has a data processing system for limiting the load capacity . There are also control and measuring devices, various indicators and lamp controls.
All elements are marked with special signs, symbols and inscriptions for ease of use.
A crane with two positions is placed on the support frame. It is designed to redistribute the flow of working fluid.
Two positions are possible, which imply different directions of movement. In the first case, the flow from the pump will go to the upper hydraulic distributor. It controls the actuators.
In the second position, accordingly, the liquid will be directed to the hydraulic distributor, which is attached to the bottom. This unit controls the hydraulic cylinders of the outriggers.
There is also a tilt angle indicator on the frame. It is used when placing the crane on supports that are controlled by a hydraulic distributor.
Price policy
We can talk about renting special equipment, which today amounts to:
- shift work from 12 to 15 thousand rubles;
- 1300.00–1500.00 rubles per hour of operation.
The rental cost depends on the scope of the proposed work, equipment, transportation costs, time of departure and arrival at the site. The cost of used equipment ranges from 400,000.00 to 2,350,000.00 rubles. It all depends on the year of manufacture of the equipment, its condition and location, and the demand for crane equipment in a certain region.
