Russian manufacturers of tower cranes
JSC Rzhev Crane Manufacturing Plant.
This is one of the largest domestic manufacturers of construction equipment. Among the most famous models of the plant are KB-473 and KB-474. The KB-473 tower crane has a lifting capacity of 8 tons and, as a rule, is used in the construction of monolithic reinforced concrete structures with a high number of floors (up to 162 meters). This technique has a semi-rotating turret and a full-rotating beam-type boom with a reach of 35–50 meters. The KB-474 tower crane is considered the highest model of domestic production. The lifting height of cargo reaches 222 meters. This tower crane is designed to perform work during the construction of high-rise buildings with a mass of mounted elements up to 8 tons.
JSC "Mashstroyindustry"
.This is a young company that united 6 plants for the production of machinery and equipment. Among the most popular models is the KB-515 rail-mounted tower crane. It has a lifting capacity of 10 tons and a boom reach of up to 50 meters. This technique can lift loads to a height of up to 96 meters. The company also offers the KB-415-07 model for performing zero-cycle work. The depth of lowering the load reaches 5 meters, so this crane can be used for excavation work.
In addition to the noted manufacturers of tower cranes, the market also includes products from the following (models KB-411, KB-504.08, KSSM-401UHL), JSC Russian Crane Plant (models RBK-5.60, KB-415, KB-404.4, KB-411- 04 and KB-411-05), JSC St. Petersburg Mechanical Plant (model KB-503B).
Main technical characteristics of the KB-415 tower crane
— altitude characteristics are given for wind regions I..II.
Structurally, the tower and jib of the crane are made in sections, which allows the crane to be assembled with different radii and tower heights. The crane tower is extended in its upper part using a hydraulically driven mounting clip. The driver's cabin can be installed at different levels along the height of the tower. The crane units are transported on standard vehicles within a width of 2.5 m. To ensure transportation, 13 walkers with a standard semi-trailer and one with a low bed are required. If you have a crane of appropriate lifting capacity for installation and dismantling, it is possible to transport the support frame with a turntable without uncoupling the turntable.

The model comes in high-quality packaging. It has an outer cardboard box that houses a metal box inside, protected by a nylon bag.
The dump body can be raised and lowered quite realistically. This is achieved by two hydraulic cylinders, which are quite tight, so the body can be installed in any position.
Tower construction cranes are designed to perform construction, installation and loading and unloading operations. A tower crane consists of a tower (column), a boom, a supporting part, a slewing ring, a driver's cabin, mechanisms for lifting loads, turning the boom, changing the reach, safety devices (load limiters, lifting height of the load, movement of the cargo trolley, turning and lifting the boom ). All crane mechanisms are controlled by the operator from the cabin, which houses the control equipment. By design, tower cranes are divided into cranes with a rotating platform and a fixed tower. For cranes with a rotating platform, the working mechanisms are installed on a rotating platform to which a tower is attached. Cranes with a fixed tower, in addition to the main parts, have a rotating head, to which, to balance the rotating part, a counterweight console with a counterweight (counterweight) is attached at the end. The cargo and boom winches are installed on a counterweight console. According to the possibility of movement, tower cranes are divided into mobile, attached, stationary and self-climbing. The supporting part of mobile tower cranes includes trolleys attached to the lower frame. In some cranes with a fixed tower, the trolleys are attached to the tower via a portal. The trolleys on steel running wheels move along the crane rail track using the crane movement mechanism. The supporting part of stationary tower cranes is a frame mounted on a monolithic base. At high heights, tower cranes are additionally attached to the structure being built. Such cranes are called attachment cranes. In some cases, an attached crane up to a certain height can operate as a mobile crane. Then it is universal and has a supporting part in the form of a running device, similar to mobile cranes. Changing the reach of tower cranes is carried out either by changing the angle of inclination of the boom using a jib winch and a jib pulley, or by moving the cargo trolley (carriage) along the boom using a traction winch. Depending on the method of changing the reach and the type of boom, tower cranes are divided into two groups: with luffing and girder booms. Tower cranes have a multi-motor electric drive powered from an external network through a cable and a pantograph and perform the following working movements: lifting loads, changing reach, turning, and mobile cranes also move. The combination of these movements allows you to transport cargo to any point in the crane’s working area, as well as serve the warehouse area and unload cargo from vehicles. To ensure the stability of mobile tower cranes, ballast is placed on the rotating platform or at the bottom of a fixed tower. The advantages of tower cranes are a good overview of the installation area by the crane operator; the location of the boom at a high height, as a result of which it does not intersect the structure of the facility under construction; simplicity and reliability in operation; large linear dimensions of the working area. Disadvantages include the need to install crane tracks (for mobile cranes), as well as install and dismantle the crane when relocating it.
About technology
KB-415 is a rail-mounted tower crane. Produced by OJSC Strommashina (Kokhma, Ivanovo region)
Capable of lifting up to 12 tons and lifting loads up to 83 meters. One of the distinctive features is sectional modules, which allow you to assemble a crane with a lift height and reach different from the original one. Extension occurs thanks to the mounting clip and hydraulic drive.
- Construction of civil structures
- Construction of civil warehouses and industrial facilities. structures
Cabin
A safety device + performance recorder is located in the crane cabin.
- Registration of crane operating parameters
- Data storage
- Parameters of crane operation and its load. (Throughout its entire service life)
The crane has tower mountings at different heights. The lowest mounting point of the tower is located at a height of 22.2 meters. When building, you can always raise the tower to a higher level. The movement of the cabin is carried out thanks to the extension cage.
KB-415 is capable of replacing outdated cranes KB-403, KB-405, KB-401, KB-408, KB-411.
