Engcon has introduced updates to two hydraulic attachments – the GRD detachable grab cassette and the SWD detachable brush sweeper – that allow them to be retrofitted without the use of hoses to the company’s quick hitches for tiltrotators.
The hoseless GRD grab cassette and SWD brush sweeper work with Engcon’s EC-Oil automatic oil connection system. EC-Oil allows instant tool and attachment changes directly from the excavator cab.
Engcon says the new GRD and SWD are part of a modular design concept that allows operators to easily add functions to the company’s products. The company has also developed a new high-flow swivel that allows hydraulic flows up to 52 gallons per min without first passing fluid through the tiltrotator valves. “The new high-flow swivel has a separate leakage oil channel, which makes it possible to drive leakage oil via the tiltrotator,” the company says.
The result is “an uncluttered, service-friendly quick hitch beneath our tiltrotators,” says Fredrik Jonsson, Engcon head of development. “It makes Engcon unique in that no other company can offer a hose-free automatic hydraulic connection system – no hoses to abrade or burst means less downtime, fewer engineer call-outs and greater profitability.”
Engcon says delivery of its Q-Safe Detachable (QSD) hitches standard with EC-Oil automatic hydraulic connectors will begin in Fall with the QSD60 for 13- to 20-ton excavators and QSD70 for 17- to 33-ton excavators, with other sizes to follow.
