Earthmoving & soil compaction

A new Caterpillar grade control system can be installed at the factory to certain Tier 4 Interim/ Stage IIIB emission compliant dozers, graders, scrapers and excavators. The technology improves operator efficiency and equipment performance while reducing the overall cost of a machine guidance system on site.

A new agreement between Volvo and Sweden's CeDe Group will see a new range of tunneling machines coming to the market.

Century deal for Volvo CE Volvo Construction Equipment sold 100 heavy excavators to mining, highway and real estate company Tang Sunrise Investment during its sales promotion in the Chinese city of Fuquing.

Caterpillar Work Tools is introducing a new line of pin-on and coupler buckets for its 374D and 390D hydraulic excavators, featuring improved designs to take advantage of increased machine performance.

Doosan is aiming its versatile DX235LCR versatile short tailswing excavator squarely at the growing market for reduced radius machines. However despite its compact size, the machine features a long undercarriage to maximise its stability. The swing diameter is under 4m, 1,070mm less than that of the conventional chassis DX225LC. Power comes from a six cylinder Doosan diesel rated at 123kW and digging force over the bucket is 14.2tonnes, while use of the power boost feature increases the forces by some 5%, w

The Guidetti Company's Earthmoving Division will unveil a number of new models. These include the new MG 100 articulated frame motor grader and CG 14 articulated tandem vibrating roller, along with Guidetti's CAESAR 1 and CAESAR 2 crushers.

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 regulations and technology are driving change in the soil compaction sector - Mike Woof reports. The impact of the Tier 4 Interim/Stage IIIB emissions regulations has been hard on some machine sectors in particular. Sloping engine covers have been introduced in several equipment categories as a way of improving visibility for operators, including soil compaction machines. At the same time, new machine guidance technologies have been developed and introduced to the soil compaction market, boosting produc

Highway construction work is transforming Algeria, providing the country with a new network of highway quality road connections. Several sections of the new trans-Algerian highway are already complete and carrying traffic, such as the stretch near the town of Setif. When complete the highway will run 1,200km across the north of the country from the border with Morocco in the west to the Tunisian border, passing through 24 provinces. This makes it the biggest highway project ever undertaken in Africa, as wel
