High productivity and value for money are two benefits claimed by the new generation of soil compactors - Mike Woof reports. The market for soil compaction machines looks to be growing more competitive as new manufacturers enter the sector. This is particularly noticeable now that Chinese firm LiuGong has moved into the sector. Meanwhile new design concepts are also allowing firms to develop much larger and more powerful machines than ever before. The choice for contractors is a wide one and manufacturers a
Construction of Istanbul’s new airport facility is benefiting from the use of a large fleet of machines from the Wirtgen Group. When it is complete, this will be the world’s largest airport and will be able to handle 150-200 million passengers/year as well as 6 million tonnes of freight/year. This will make the facility substantially larger than the world’s current largest airport, the Hartsfield-Jackson Atlanta International Airport, which handles around 105 million passengers/year.
Made for DTH production drilling in soft to medium hard rock, the new Secoroc RocketBit from Atlas Copco Secoroc is said to be ideal for quarrying and mining operations. Also claiming success in water well drilling, the innovative drill bit has been put through Atlas Copco’s digital wind tunnel simulating the best angles and deep grooves. This design solution is said to have created more space between the forged steel bit body and rock face, thereby optimising chip removal. The Secoroc RocketBit claims to o
Infrastructure investment means that the road tunnel construction sector is healthy due to demand for new links – Mike Woof reports
With many emergent nations investing heavily in infrastructure, the tunnelling sector is seeing extensive business at present. Tunnels provide key links in mountainous areas or in congested cities where building roads on the surface may not be practical. In Asia and Latin America, many key road connections are now being built underground to pass challenging terrain or provide
