Crane overpass for supporting crane
Workshops use support structures (columns) for the crane path. At the same time, the columns carry longitudinal and transverse loads. Beams with a rail are installed on the console of the columns. The installation of such structures is more difficult if they must fit into the existing parameters of the room.
A crane overpass for a support crane is an engineering structure that holds a beam with a lifting mechanism and ensures horizontal movement throughout the workshop, warehouse and hangar.
The construction consists of the following elements
Support. Vertical columns carrying the main load from the rail track, end beams, crane-beam and load-catching mechanism. Can be installed in the foundation of the building or distribute the load on the load-bearing walls, through additional fastening elements; span horizontal structure. It is placed on vertical columns, increases strength, allows you to lay rail tracks.
Overpasses are needed for the rhythmic and productive work of certain types of crane loading and unloading equipment.
Such structures help to place cranes at a height during their lifting functions and are used in various industrial areas: on construction sites, cargo terminals, etc.
The crane overpass for the support crane is mounted in workshops, hangars, production facilities, as well as on open areas. Open type overpasses are most often mounted on sites on their own foundations. Such foundations are strengthened by trusses and are able to withstand the load of the columns.
The advantages of crane overpasses include
Simplicity and economy. The cost of the overpass is lower than the design and construction of a special building.
Ergonomics. Such structures make it possible to lay the path of freight transport in different directions (for example, across the movement of a bridge crane). At the same time, the productivity of work on the movement of goods increases. Support cranes have good operational engineering characteristics.
To the disadvantages of the construction can be attributed
Propensity of open structures to atmospheric influences. This makes them less durable. Carrying out industrial works puts constant loads on the foundation and soil. As a result of deformations, the width of the under-crane paths may change.
These nuances must be taken into account during installation. Competent specialists need to be engaged to perform the work. Then all negative impacts can be minimized.
