Reduced emissions represent a key development for Ammann's asphalt plant technology. The firm’s advanced VRD filtration system from Ammann is able to remove a significant level of emissions, as well as being self-cleaning.

The Ammann VOC Reduction Device (VRD) reduces volatile organic compounds (VOCs), odours and other organic carbon emissions. It is the first technology on the market able to self-clean; no filter replacements are needed.

A novel system from Trimble offers the basic capabilities for both surveying and machine control. This is a solution aimed at use on compact machines weighing no more than 15tonnes.

The firm says that the new system is designed to be used by smaller firms looking to start using machine control technology, but without wanting to invest in costly and sophisticated packages.

The multitool approach allows smaller contractors both basic surveying and machine control capabilities in a simple package that is said to be easy to use.

Trimble is offering a simple survey system as a subscription package only.

The new tool is aimed at use by site managers or small contractors wanting to carry out their own basic surveying work for small projects. The package is offered with a monthly fee and comprises the DA2 antenna and TDC6 controller.

The DA2 unit is simple and rugged and a spokesperson for the firm said, “It’s a very basic antenna.”

Meanwhile, the TDC6 controller is the size of a smart phone and the spokesperson commented, “It’s really handy.”

Increased performance is claimed for Kobelco’s SK520LC-11E excavator, which is now being offered in two variants.

The standard model is the SK520LC-11E model, however there is also the new SK520LC-11E Mass Excavation variant, for specific application needs. Both models weigh from 52.9-57.2tonnes, depending on specification and have power from a six-cylinder Isuzu diesel rated at 348kW that meets Tier 4 Final/Stage V emissions requirements.

Versatility is the key feature of Kobelco’s new SK380SRLC-7 excavator, with its short tailswing design allowing operation in restricted space areas. Operating weight varies from 36.8-39.4tonnes depending on the specification and the machine is powered by an Isuzu diesel delivering 210kW that meets Tier 4 Final/Stage V emissions requirements.

Trimble has developed a cost-effective machine control package aimed at use by firms looking to use this technology, without spending heavily. This system uses the firm’s BX992 receiver and is designed to be used with excavators only.

The BX992 receiver can be fitted to the machine and costs considerably less than other systems on the market. As the unit is fixed to the excavator it is for use with that unit only.
