CompLogger, a new hand-held compaction control system is being introduced by Dynapac as a soil compaction analyser. It provides a real-time image of compaction over the entire surface to be compacted. The easy-to-use unit can be used for production planning and throughout compaction and the data can also be saved for future quality control and evaluation.

With the Tier 4 interim/Stage IIIB emissions requirements due next year, further upgrades will be required for all wheeled loaders sold in Europe and North America. In the mean time manufacturers are focussing on improvements that cut cycle times, boost productivity and reduce downtime for example. From Doosan comes the DL420 wheeled loader, which takes over from the previous DL400 and is aimed at use in a range of materials-handling work. The DL420 features a 4m3 bucket and is a 22.3tonne machine that

New Holland is introducing new models of heavy-duty crawler excavators. The E385C and E485C are in the 35tonne and 48tonne category respectively.

A transfer of responsibility is planned for bridges in Qeubec, Canada. Structures currently under the responsibility of the Canadian Federal Government may be handed over to the Quebec Government, should proposed moves be made. This policy looks likely to include the Jacques Cartier Bride. After the completion of the Champlain Bridge, planned for for 2021, the Federal Government may hand over the bridge to the provincial government. This is due to the Federal Government's lack of sufficient funds for the pr
