Laying high voltage lines without crop damage
Under ideal ecological circumstances, the electricity for the operation of the electric engines comes from renewable energy sources. In order to allow the green electricity generated by wind farms, for example, to actually reach every electrical outlet in Germany, the country needs several thousand kilometers of new power lines. The high-voltage direct current transmission lines should primarily
be realized as underground cables. Herrenknecht AG from Schwanau/Germany is going to present a new, economical and environmentally friendly laying method at bauma 2019. The modified E-Power Pipe drilling technology enables trenchless laying of cable conduits across comparatively long distances of more than one kilometer close to the surface at a depth of two to four meters. This minimizes interference with the landscape. The jury found this solution worthy of a nomination for the bauma Innovation Award— not least as a contribution to the turnaround in energy policy in Germany.
Raw materials instead of spoil heaps
One key requirement for sustainable behavior and operation is the conservation of resources. Among the technologies in demand here are those that allow exploitation of raw materials in spoil heaps—such as the new shaft spiral separator SWS 3000 from manufacturer Doppstadt in Velbert/Germany. The device is able to separate strongly cohesive material mixtures, for example stones from sticky mud or clay. As a result, the volume of spoil heaps is reduced and the life of the quarry is extended by the extraction of raw materials from the original “waste”.
Locally manufactured wind turbine towers
A bauma innovation that “serves” all three traditional fields of sustainability—ecology, economy and society—is the mobile manufacturing of Max Bögl Wind AG. The company from Neumarkt/Germany is known for the manufacture of hybrid towers made of concrete and steel elements for wind turbines with large hub heights. The new concept involves the manufacture of the concrete elements in a temporary factory delivered in 262 containers close to the future location of the wind turbines—upon request to almost any place in the world. For example, 90 towers for a wind farm in Thailand were manufactured as part of the pilot project launched in August 2017. Local raw materials and manpower ensure local added value and increase the profitability of the project. At the same time, a reduction of the number of heavy-load transports contributes to the protection of infrastructure, climate and environment. The globally unique manufacturing concept has also been nominated for the bauma Innovation Award.
bauma: key facts about the world’s leading trade fair.
bauma is more than the world’s leading trade fair: it is the heartbeat of the industry. It sets the pace. Dynamizes the market. And drives business. With one paramount goal: to always already focus on the next challenge. Because it’s not just about the status quo, but about the future. Because it’s not just about individual perspectives, but about the big picture: the construction, building material and mining machine industry in its full dimension.
It is the largest international meeting place and most important multiplier for the industry. The reason: bauma’s global network and digital touchpoints do not only reach the trade visitors at the exhibition itself, but the entire industry around the globe. A reach that is of benefit to both exhibitors and visitors. Because to be present at bauma means to have access to all markets, to all target groups, to all decision- makers.
