Continued improvements in coupling systems allow for easy handling of attachments

Electronics are becoming important in improving machine productivity

Provision of optimum operator comfort is proving to be another key focus area for excavator manufacturers

Telemetry solutions have become the gold standard of the equipment industry

Most hydraulic operated attachments can now be fitted to the Kobelco range of excavators without the need for any modifications as machines come factory- fitted with two-way piping with foot- operated controls.

the SK500. Kobelco machines also allow for the switching between single and bi- directional hydraulic flow within the cab.” DISA Equipment, operating as Doosan South Africa, recently introduced its 51 t Doosan DX520LCA and one of the key features is the machine’s improved heavy duty boom and stick for better handling of attachments. Overall reinforcement of steel on the boom and arm was achieved through a 20% increased thickness on the side plate and 15% on the bottom. Its 7,1 m boom and a shorter 2,9 m stick translate into better breakout force, especially in taxing working conditions. This makes it a perfect fit for running heavy duty attachments such as hammers and crusher buckets. The Doosan DX520LCA excavator also comes with standard hydraulic piping for work tool applications. In many of the competition’s offerings, this is said to come as an extra. This feature alone can cost in excess of R150 000 to install where it comes as an extra. What is more is that the main high-pressure lines from the main control valve to the pump have been changed from a combination of pipes and hoses to entirely hoses to minimise

the risk of leakages. Instead of the resin (synflex), the hoses are now made from full rubber (Acryl nitrile butadiene). The new material, combined with a new fitting, reduces bending and therefore ensures sound hydraulic flow, while reducing internal pressures. Roger Teece, Product Manager for Volvo CE, Sales Region EMEA, says apart

from hydraulic improvements, to optimise attachment usage on its machines, Volvo CE offers a range of quick couplers, allowing the operator to quickly and efficiently change between attachments. “In certain markets and certain models, we have a Tiltrotator system available as factory fit, which provides ultimate versatility for our excavators,” says Teece.
