Engcon improves automatic coupling for hydraulic tools

Engcon, the world leading manufacturer of tiltrotators and attachments, has updated its fully hydraulic EC-Oil solution, which allows the safe automatic connection of hydraulic tools from the operator's seat. The biggest development is a completely newly engineered electrical connector featuring a blade-type design. The new style connector has increased contact surfaces and has been moved to the top of the hitch to provide better protection from oil and dirt.

EC-Oil's new electrical connector has 12 robust blades in two banks of six that make it even more durable than its predecessor. What’s more, the updated EC-Oil was rigorously tested during the winter of 2016/2017 with approximately 100,000 couplings in varied environments including dirt, salt water and snow. The tests have made sure the new EC-Oil can handle really tough working environments.

“The test results were all very positive and show that this improved EC-Oil can handle really tough working environments," says John Lundqvist, Test Manager at Engcon's R&D department in Strömsund. Sweden.

Unique wedge shape allows maximum contact

John goes on to explain that each pin in the connector is wedge-shaped and when connected, is inserted about 20 mm into the spring-loaded female half of the connector. This provides a cleaning effect with maximum contact in every position, which reduces the risk of the excavator losing electrical contact with the tiltrotator.

“We also want to emphasise just how robust EC-Oil hydraulic connections are," says John Lundqvist, explaining that each movable part of the hydraulic connector (both female and male) has an O-ring seal that is easy to access, making maintenance simple. This is also the only O-ring on the redeveloped EC-Oil blocks; which , together with the flat face of the connectors making cleaning easier, has been designed with the operator in mind.

“The simple, robust design also makes EC-Oil the market's best value-for-money solution for fully hydraulic couplers,” adds John.

This latest EC-Oil will be launched at Plantworx in June 2017

Engcon will be displaying the new EC-Oil at Plantworx and will be available with the Q-Safe quick coupler in sizes QS45 through to QS80 for excavators from 6 to 33 tonnes. The QS60 will be first with initial deliveries anticipated for the middle of June 2017; the other sizes will be introduced throughout the summer and autumn of 2017.
