Engcon to launch automatic quick coupler for tiltrotators on 4- to 6-metric-ton machines
Engcon will launch the EC-Oil quick coupler system during spring 2022 for the lower quick coupler on the EC206 tiltrotator for four to six metric ton class excavators. This means that hydraulics, electronics, and central lubrication are connected automatically while the driver remains in the cab, increasing both efficiency and safety.
In 2020, Engcon introduced the EC-Oil automatic oil and electrical coupling as standard on the S40 machine hitch and for the upper part of the EC206 tiltrotator for machines up to six metric tons. Now Engcon is taking a step further and introducing an EC-Oil automatic quick coupler system for the lower quick coupler on EC206 tiltrotators.
"It is both convenient and saves valuable work time for operators by not having to step out of the cab to connect with manual, pressurized, and dirty hydraulic couplings, contributing to improved efficiency and safety for our end users," said Martin Engström, product manager at Engcon. "After we introduced EC-Oil as a standard for our tiltrotator systems, sales have significantly increased, which indicates that the combination is appreciated by our customers and end users."
The lower quick coupler of the S40 also gets several extra hydraulic outlets as well as a smart function with the possibility to connect a detachable gripping cassette. It is now planned for sweeper rollers and other tools.
"Detachable gripper cassette means that the driver can easily and quickly disconnect the gripper when it is not needed," said Engström. "It is a weight saving of about 77 lbs and if you count how many times you lift the bucket in a day, it quickly results in a fuel-saving and reduced wear on the machine."
Extra equipment enables higher oil flow
Engcon has also chosen to equip the EC206 with a completely new swivel with increased capacity and more outputs for extra hydraulics on the quick coupler S40 under the EC206.
In addition to this, there is an extra socket on each side of the quick coupler and an extra socket on the back of the bracket. Extra sockets on the side of the quick coupler bracket are also possible, feeding directly from the excavator's extra hydraulic socket. This then enables a higher oil flow than the outlets that are controlled via the tiltrotator's valves and enables the operation of, for example, slope mowers or other tools that require slightly higher oil flows.
Martin Engström says that with the new swivel it also has the advantages of not having any hoses in the lower quick coupler
"It will be the same concept as the larger models where the EC-Oil blocks and extra sockets are screwed into the bracket," said Engström. "On the S40, the locking cylinder is also screwed directly into the block, and this means that the bracket has no hoses or moving parts that rub and cause wear. We know how crowded it can be to screw inside a tool holder, so this is a big step forward in terms of service friendliness."
Additional features on the new EC206 include the ability to equip it with both tilt and rotation sensors for the machines that have machine control systems.
The EC206 with an S40 automatic quick coupler will be presented at trade fairs during the year and a smaller pre-series will be delivered during spring 2022. A production run is planned for the fall of 2022.
