The forthcoming Tier 4 emissions legislation represents a great leap forward in technology, Mike Woof reports
A high-profile focus on sustainability and reduced environmental impact is sweeping the construction sector in the European Union (EU) and the US. The EU and the US will implement regulations for the lowest emission off-road machines in history, with Canada and Japan expected to release similar regulatory programmes this year.
The legislation being introduced will transform the construction indu
Soil compaction BOMAG is pushing technological boundaries in the soil compaction sector with the market introduction of its giant 32tonne machines, which was shown in prototype/concept form at bauma in 2007. According to the firm the concept model attracted considerable interest and the company opted to develop the unit for series production. The new BW332 single drum roller is now the heaviest such machine on the market.
In recent years developments in engine technology have played a key role with regard to improved machine performance. Diesel engine makers have had to meet a challenging schedule in terms of delivering new low emission engine technology and meet tough regulatory requirements for the US and Europe. Along with the cleaner emissions have come improved fuel economy and increased power density, allowing customers to meet the power needs of their machines with smaller and more economical engines. At the same time
