Henkel Offers innovative technologies for the construction of the most modern elevators

During years, the adhesive of high provision have gone substituting to the classical technologies of union - the use of rivets, screws, bolts and weldings - in multiple industrial states of increasing way, by his optimum aesthetic finishing, a cured fast to temperature acclimatise, and because practically they do not occupy space (usually a fine layer of adhesive is sufficient to create a clean and reliable union).

This tendency also reflects in the construction of elevators. During a lot of years, the adhesive have showed to be ideal for the manufacture of elevators of one or several passengers, storage lifts or elevadores for the transport of commodities, observing an increasing evolution in this tendency. The reason is that the adhesive offer an unbeatable combination of properties convincentes for the different communities:

- The engineers appreciate the improvement in the distribution of the tensions, especially on wide surfaces or in the points subjected to high loads.

- The operarios benefit of the reduction of the works of maintenance, by not speaking of the greater energetic efficiency and the reduction of costs.

- The users enjoy of a more exclusive experience with attractor trucks pleasant inner designs in sight.

- The manufacturers and his providers discover with frequency that can optimise the processes of production and, in this way, reduce the costs and the energetic consumption.

The adhesive structural offer a crowd of possibilities that do that all this was possible. The adhesive structural used in the Shard, for example, joins the fixations of the doors of the cabins of double leaf with each one of the axles. Of this way, diminishes notably the weight of the constructions and reduce the wear of the materials.

Only with the use of adhesive, the cabins of the elevators can see reduced his weight until a 20 percent without experiencing any merma regarding the performance. One of the main reasons is that the adhesive allow to use material finer and light. For example, the cabins can manufacture with metallic ironingings the half of thick that the used in the conventional designs. To the equal that sucede with the welding, the adhesive applies in the no visible zone of the panels. And the adhesive by himself same have an effect stabilizer and of reinforcement on the group of the setting. Besides, the resistance and real stability of a face of the elevator achieves adding a profile omega joined to the external face of the signpost. The adhesive selected for these applications characterise by a high adherencia initial.

Since the adhesive do not modify the surface of the materials in contact, is not necessary to realise extensive aesthetic retouchings. If the panels are joined with screws or by welding, usually is necessary to cover the points of union with coatings additional, like minimum in the cabins thought for customers and visitors. This increases even more the weight of the cabin and the necessary work. In the case of the remachado, the material shapeless and causes irregularities antiestéticas in the surface.

The reductions of weight that achieve with these solutions have a direct and positive effect on the energetic needs of the elevators. The adhesive already are an essential part of the new generation of elevators of high speed that are installing at present to world-wide level – and that offer greater speeds of start, doing them more attractor trucks for customers and visitors. The current record has it Taiwan, where the elevators move to the passengers to a speed of 60,6 kilometres by hour, that is to say, 16,8 metres by second.

The lightest cabins impose , apart from in speed, in comfort and confort. Also they do it in the manufacture of storage lifts, in where it is necessary the transport of loads very high. Here, the use of adhesive can derive in an increase of the maximum load allowed. Regarding the rest of provision, the greater energetic efficiency translates in a reduction of the energetic consumption and of the operative costs since – thanks to his reduced weight – an elevator joined with adhesive, precise less electricity to achieve the same performance. Of the same way, also can consider the use of motors smaller and economic for the same level of loads.

This radical change in the technologies of union also does visible in the design of the electrical motors. Increasingly the adhesive for the union of magnets are substituting the methods established – abrazaderas and grapas – so much in the rotor as in the stator. Besides, the magnets joined with adhesive exhibit a better operation and an useful life more prolonged thanks to the lower degree of vibrations and of noise. They can resist the thermal sensors tensions, are resistant to the impacts and do not present any type of corrosion. In this segment in particular, Henkel offers adhesive vanguardistas in terms of optimisation of the performance and efficiency of costs.

The adhesive also allow to follow the tendency – satisfying the exigencias of the owners of the buildings – in the research of solutions more respectful and compatible with the environingingment. The energetic saving that achieves by means of the constructions of cabins lighter is only one of the appearances in this context. The use of adhesive involves a better conservation of the resources and a greater energetic efficiency because, unlike the setting by welding (for example), do his work without need of any external supply of power. They toughen entirely to temperature acclimatise and offer time of cured shorter in the production of the elevators, contributing in this way to the saving of costs and optimisation of the processes.

The change to modern technologies and more respectful with the environingingment also does visible in the case of the metallic components, installed so much inside as out of the habitáculo. An example find it in the technology advanced of protection nanocerámica against the corrosion. With her, Henkel is able to offer to the companies of processing of metals, a wide fan of processes of pretratamiento more efficient and medioambientalmente safe. Compared with the conventional technologies of treatment of surfaces, the option nanocerámica reduces the time of the process until a 50 percent, reducing significantly the works of repair and maintenance of the machinery, the consumption of water and the waste, since the application of these coatings of protection against the corrosion takes place to temperature acclimatise. This technology also can derive in a reduction of the energetic costs of until the 30 percent.

Is little likely that the metals lose his dominant position in the construction of elevators in a near future. However, other materials are winning attractor trucks. Every time they incorporate more installations of glass, plastic and LED in the cabins of the elevators to create exclusive environingingments. Besides, the methods of light construction that have made possible the adhesive open new doors for the creative design. With the adhesive can connect material without the need of taladrar or solder. This gives foot to create combinations of materials that go further of the conventional. And Henkel offers adhesive of high provision for all type of decorative materials, like glasses (mirrors), plastics, marbles and metallic ironingings treated with painting in dust or simply painted. The adhesive join of durable form without generating mechanical tensions and can signal the way to new concepts of design of interiors.

Also can implant treatments insonorizantes modern that optimise the reduction of the noises and the vibrations. It has checked that the materials insonorizantes pulverizables of Henkel are especially effective in these applications because they can direct specifically to the zones in which more it requires the acoustic isolation. Besides, the thickness of the layers can measure with precision, deleting the cost of product in excess.

Given this crowd of profits, the elevators of high technology used in the Shard, included the cabins of two flats, manufactured doing an extensive use of technologies of Henkel. And in cientos of public buildings, blocks of flats and stations of trains, the adhesive will follow joining and attaching of form totally discreet.

Only in Europe, the owners of real estate and the promoters install around 100.000 elevators in new constructions or installations reformed every year. In the increasing markets in growth of Asia the figure is a lot greater. And all over the world it does not leave to grow the number of projects in which the adhesive, with his boundless group of advantages, are substituting to the technologies of union previously established.
