Davits are installed in the sockets on terrace floors or inner surfaces of the parapets.
These arms consist of a body surpassing the height of parapet and a swivel head part. The rotating arm system enables the platform to surpass the parapet and lower it to the surface of the building. The whole surface is accessed on equal axis as the davit arms are disassembled and assembled into neighbouring sockets.
The most important advantage of the Davit system is that the platform could be parkeci on the terrace.
