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. The Holland said that they have been built deal with the most demanding applications and harshest conditions. The latest models offer more power and fast cycles with new Tier 4 interim engines and new hydraulics. Fuel consumption is improved through the new hydraulics and new ECO working mode.

The Zoomlion HCC-80 is the latest edition to its crawler crane range. Weighing in at 72.5tonnes, GCS says the HCC-80 is easy to transport, and is among the first in the industry to meet ANSI standards for safe operation. The crane is also said to be ideal for general construction, bridgework and pile driving applications, as well as oil refinery and power plant work.

Using Ammann’s AS1 plant control system, the EcoMix concrete plant combines accurate measuring equipment and comprehensive process control to guarantee perfect, repeatable results, claimed Ammann. The galvanised steel support structure is light, warp resistant and also suitable for areas of increased seismic activity, it is claimed. The EcoModule is equipped with the company’s tried and tested Amix twinshaft paddle mixer and is pre-assembled and tested at the factory.

The conveyor units for Sany’s new SYG 5260 THB 36 and SYG 5320 THB 42 concrete pumps are fitted, according to the company, with precision electronic controls that act as ‘electronic brains’ to store vital data. Any errors trigger an instant notification in the colour display. The built-in hydraulic drive unit saves up to 20% of energy. Another key feature is the fully hydraulic sequence control of the conveyor unit in a secure and open hydraulic circuit. The automatic pressure equalisation when switching th

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
