Ladders – without them development of a human civilisation, probably, would be impossible. Such idle time, and simultaneously the functional device allowed (and allows till now) to get to tops which have not been intended by the nature for the person. But that that the person could outwit the nature has made its civilised. The adaptation – the main weapon of kinds under the theory of Darwin. And one of such adaptations at the person – a ladder. We had not to evolve and grow to 10 metres up to get beer honey and eggs of birds from hollows, or to build idols, and later and difficult many-storeyed buildings that in them on high regiments to put books and vases.
Wooden loft ladders were very heavy, but all the same them did, after all, without looking at all at dearness of natural wood at all times, the purposes justified spent resources. How many unapproachable fortresses were is taken by means of ladders which were put to high stone walls. Certainly with development of technologies and ideas of humanism of a ladder have ceased to do of a tree – anyway it now not a mass production product, and wars became much less bloody and senseless.
Aluminium ladders – here that has come in the stead of wood. The lungs, capable to be transformed, they serve for the same purposes, as earlier, and with service consult perfectly well.
Probably, in each country there is a manufacturer of ladders, after all these goods are specific enough and to export it not so favourably because of marker, and accordingly and dearness of transportation. So in Belarus it are . Company production in Russia occupies leading places on a corresponding market segment. Step-ladders at all do not concede to foreign analogues. And than to concede – manufacturing techniques of ladders some thousand years have not too changed for the last. However, the company nevertheless improves technologies and a design of ladders, as does by its leader in the market.
Therefore if to you has bothered to search for a stool, and then standing on it also to be extended on tiptoe, to get from mezzanines the necessary thing why simply not to buy a step-ladder? And can be to you the simple ladder will approach even? All depends only on problems which should be carried out with a ladder.
