See full text

A gripping device, rock drilling unit and method of gripping drilling tools is disclosed. The gripping device includes a frame and at least one elastic gripping element connected in a fluid-tight manner to the frame. The gripping element may be expanded by conveying pressurized fluid between surfaces of the frame and the gripping element, whereby the gripping element moves against surfaces of the drilling tool and generates friction forces and support.
