Cutoff device for crane systems |
摘要 |
The cutoff device is provided for crane systems, especially a dredger to which a grab 1 is attached. Grab 1 has a cable 5 connected to it, which is guided over pulleys 4, 7 and kept under tension with the help of a weight 9. One of the two pulleys 4 is provided with an initiator 12 that has segments mounted on its periphery, so pulses are generated by the rotation of pulley 4 past the initiator and the drive mechanism is switched off when the pulses fail to occur.
