Earthmoving equipment can include a wide variety of different types of construction equipment – this feature will focus on excavators, bulldozers and backhoe loaders.

The D6 and D6 XE offer a choice of technology options

Doosan recently launched the new DX350LC-7 Stage V 36 tonne crawler excavator. This is the first Stage V model to feature Doosan’s D-ECOPOWER technology, which is said to provide operators with higher productivity and lower fuel consumption per hour, as well as smoother controls.

The technology focuses on the role of the hydraulics system. It utilises an electronic pressure-controlled pump within a closed centre hydraulic system to accomplish increases of up to 26% in productivity and up to 12% in fuel consumption improvements, depending on the mode selected. A closed centred main control valve minimises pressure loss, while the electric pressure-controlled pump manages and optimises engine power.

Caterpillar’s new D6 dozer is said by the company to deliver new levels of performance with a choice of Electric Drive or Fully Automatic power train. Customer profitability is reported to be enhanced with up to 35% better fuel efficiency and reduced service and maintenance costs, while a new cab offers more operator comfort.

While there are a host of new features, with the D6 XE being the world’s first high drive Electric Drive dozer this is sure to be an area of interest. Caterpillar introduced the first dozer with electric drive more than ten years ago, but this is the world’s first high drive electric drive dozer.
