The engcon EC-Oil system for allows quick hydraulic tool changes in tough environments

At the Bauma trade fair, engcon will be displaying its next generation hydraulic quick hitch, the EC-Oil system. The quick hitch is available in several sizes, and allows rapid, secure changes of hydraulic tools, without the operator needing to leave the cab. ”The EC-Oil has been developed for maximum reliability in dirty and demanding environments. Thorough lab tests and field studies show that we have succeeded in our ambition,” says Sten Strömgren, Communications Manager at engcon Group.

The Swedish company engcon is a world-leader in the development of tiltrotators – the excavator’s ’wrist’ enabling the operator to rotate and tilt the bucket or tool that is being used – and has produced a complete tool range to further increase the flexibility and profitability of an excavator. This company has the new generation of quick hitch, the EC-Oil, with an entirely automatic connection of hydraulic and electrical fixings.

The new EC-Oil has been created for maximum operating safety in demanding environments. The proprietary oil and electrical connections are designed to be even more resistant to the often tough working conditions for excavators.

Safe design
The EC-Oil system has no hoses or electrical cables that move during connection, reducing the risk of crush injury, damage, or wear. There is also mechanical protection which prevents the bracket being incorrectly connected, reducing the risk of breakdown. The in-built pressure relief valve enables the tool to be changed whilst maintaining complete system pressure.

”Our focus was to create a robust design with maximum operating safety. Our wear tests show that the EC-Oil can cope with thousands of connections/disconnections, even in dirty conditions, without function being affected”, says Sten Strömgren.

Complete freedom of choice
The EC-Oil, together with an engcon tiltrotator, allows an excavator to achieve maximum flexibility, safety and profitability. The EC-Oil permits the operator to use the exact tool combination needed for each task. For digging, when the tiltrotator is used to its full advantage, the EC-Oil can be used for incredibly rapid tool changes under the tiltrotator. On the occasions that the tiltrotator is not required, it can be disconnected as quickly and simply as the tool under the tiltrotator; for example, when maximum breaking force is required when digging harder materials. This also saves weight, which means fuel savings and a better total economy. The EC-Oil also gives the operator the chance to quickly remove the tiltrotator if a minimum breaking width is needed when digging deep, thin shafts, where there is not enough space for the bucket to be rotated.
