Coupling system for a hoisting device on boats includes a lifting device designed as engaging coupling probe to make a positive fit into a retaining device

摘要

A self-induced magnetic field pulls an engaging coupling probe (2) near a ferromagnetic retaining device (6) in the direction of a retaining cone (8) on the ferromagnetic retaining device. Because of its mass, the engaging coupling probe falls at the same into the retaining cone on the ferromagnetic retaining device and is centered through the positive-fit shape of the retaining cone. An independent claim is also included for a coupling device with a measuring device having a transmitter for sending laser beams, a reflector plate for reflecting and a receiver for picking up reflected laser beams.
