Abstract (en)
A machine tool has a movable lifting arm 1 and a tool 21 coupled thereto. The lifting arm 1 has two coupling forks 5 and two movable coupling pins 7 that are coupled to the tool 21. The lifting arm 1 further has first hydraulic coupling pieces 11. The tool 21 has two coupling bars 23 to which the coupling forks 5 are coupled, two coupling eyes 25 into which the coupling pins 7 are inserted, and second hydraulic coupling pieces 27 to which the first hydraulic coupling pieces 11 are coupled. The tool 21 further has two pins 29 and 31 that are connected to each other, of which one pin 29 is moved by one of the coupling pins 7 during insertion into the coupling eye 25 and the other pin 31 depresses a switch 15, which switches on moving means 17 that move the first hydraulic coupling pieces 11 so that they are coupled with the second hydraulic coupling pieces 27 on the tool 21.
