Safe connection of hydraulic tools from the operator's seat

Engcon is updating its fully hydraulic EC-Oil solution, which makes the safe automatic connection of hydraulic tools possible from the operator's seat. The latest EC-Oil is a newly developed blade-type electrical connector with increased contact surfaces. It's been moved to the top of the hitch to protect it better from oil and dirt. 

EC-Oil's new electrical connector has 12 sturdy pins (6 + 6) that make it even more durable than its predecessor. What's more, the improved EC-Oil was rigorously tested during the winter of 2016-2017 with approximately 100,000 couplings in varied environments including dirt, saltwater and snow. The tests have made sure the improved EC-Oil can handle really tough working environments. 

"The test results have been nothing but positive," says John Lundqvist, test manager at Engcon's R&D department in Strömsund. Sweden. 

The pins in the connector are wedge-shaped and, when connected, are inserted about 20 mm into the spring-loaded female half. This provides a cleaning effect with maximum contact in every position, which reduces the risk of the machine losing electrical contact with the tool.

"We also want to emphasize just how robust EC-Oil hydraulic connections are," says John Lundqvist, explaining that each movable part of the connector (female + male) has an O-ring seal that is easy to access, making maintenance simple. It's also the only O-ring on EC-Oil; the connectors are instead sealed through their smart conical shape.
