To install the bridge crane, the beam crane must be installed crane tracks. Crane tracks are special structures, the main task of which is to take loads inevitably arising in the process of operation of any lifting equipment. Given the fact that the enterprises today use cranes with a carrying capacity of 10, 30, 50, 80 tons or more, the designated loads can be more than tangible.
Crane tracks are usually made of steel or reinforced concrete. The material of the implementation of crane beams is determined by their subsequent use. So, steel crane beams are used for cranes of any carrying capacity, they can also be used when using reinforced concrete columns with increments of more than 12 meters. Concrete beams can be used for cranes with a carrying capacity of 20 to 32 tons, as well as when using reinforced concrete columns with steps of 6 and 12 meters.
The beams may have a tavro or two-tavro section, with a developed upper belt or with belts of the same width.
In company. Synthesis TMK. works on the construction of ground and above-ground crane tracks are carried out only in accordance with the requirements of regulatory documents, and an additional guarantee of the quality of the work performed is provided by the high qualification of engineers and staff of the company.
FREE WAYS
The type of crane path depends on the characteristics of the lifting equipment used in the enterprise.
Distinguish:
The initial data for the works, which include the installation of cranes, cranes and beams on which they move, are the results of the survey of the construction of the building, allowing you to calculate the bearing capacity of the columns of the workshop, as well as passports and certificates for equipment. Important is also the technological layout of the shop, allowing you to determine the boundaries of the working area. These data must be provided to the installation organization before the start of work, regardless of what is planned to do: installation of crane tracks for GPM or installation of beams for a winch.- Ground crane paths. These include the crane paths of tower, portal and gantry cranes. Such paths involve the construction of the upper and lower parts. At the top of the ground crane tracks there is a rail and ballast, and at the bottom there is a drainage system and rammed soil.
- Overground craneways. These include crane paths of bridge cranes or their lightweight analogues of cranes. Depending on the methods of fastening, such paths can be supportive when placed on the columns of the building or free-standing overpass and suspended with attachment to farms and floors.
Design and installation of right-ways
Specialists of the company “Sintez TMK” have all the necessary knowledge for competent installation of crane tracks. Engineers and installers of the company will compile a task for the design and manufacture of crane tracks, conduct the necessary surveys, perform design work and develop RRP, perform installation work, conduct acceptance tests, issue executive documentation and pass crane tracks into operation. But work begins on the installation of any crane paths with familiarization with the basic source documents provided by the customer.
Engineers of Synthesis TMK conduct all instrumental examinations of load-bearing structures on site
If the customer can not provide the necessary data, engineers “Synthesis TMK” go to the shop, on the spot conducting an instrumental examination of all load-bearing structures. Based on the result of this study, a report is compiled on the basis of which the type of section and length of future crane paths are determined. These characteristics depend on the specifics of the room and the planned weight of the transported goods. The result of the research is a project at the working documentation stage, consisting of text and graphic parts.
The draft crane paths should take into account:
- Characteristics of the crane, load capacity, operating mode, speed, loads;
- Flight and lift height of the crane;
- Temperature operation of the equipment.
After approval of the project with the owner of the building and supervisory authorities, a project of production works is developed, which determines the method of safe installation of the structure, storage of materials, safe working conditions and other important aspects.
The next stage is the ordering of materials, installation of rails of crane tracks and other structures. Then conduct the test and adjust. After the installation of suspended crane tracks is completed and the system is ready for operation, all executive documentation is compiled and transmitted to the customer.
Facility development
When installing crane tracks, mandatory checks of the geometry of the system, which are performed by the geodetic service, should be regularly carried out. Depending on the load capacity and category of the crane, its use is agreed in Rostekhnadzor, where the equipment is entered in the register and issued a registration number. During the design, special attention is paid to strength calculations, deflection calculations and other technical indicators responsible for safe operation, important for leveling crane tracks. The tolerances established by the project should not be violated.
Specialists “Sintez TMK” take on not only the installation, but also the manufacture of crane tracks
Specialists of the company “Sintez TMK” are able to ensure the manufacture of crane tracks, which are connected using a weld or bolts, install brackets on the columns and place the structure on them. After installation, the experts of the enterprise will conduct the necessary tests and verification of the crane tracks. Sintez TMK has the necessary experience in performing such works as installation of suspended crane tracks, installation of crane tracks of bridge cranes, tower cranes, as well as a service for dismantling crane tracks. Engineers of Sintez TMK will perform all the necessary work, conduct acceptance tests, issue executive documentation and put the facility into operation.
