GRAB DEVICE AND METHOD FOR OPERATING A GRAB DEVICE
The invention relates to a grab device with a carrier implement and a rope grab arranged thereon which has a grab frame which is held on the carrier implement via a holding rope, at least two grab shovels which are pivotably supported on a lower end of the grab frame between a closed position and an open position, and an actuating means with an actuating rope for pivoting the grab shovels, wherein an actuating rope is guided from the carrier implement to the actuating means and the carrier implement has a driven first rope winch for the holding rope and a driven second rope winch for the actuating rope. In accordance with the invention provision is made in that a first detection means for detecting a first rope force on the holding rope and a second detection means for detecting a second rope force on the actuating rope are provided and in that a control means is provided which is connected to the first detection means, the second detection means, the first rope winch and the second rope winch and which, depending on the detected first rope force on the holding rope and the detected second rope force on the actuating rope, is designed to activate the first rope winch and/or the second rope winch according to a control program specification.
