ABSTRACT:
The invention provides a load moving device, especially a ship's winch in which the driving ratio is varied infinitely in accordance with the varying load, the device including a pair of eccentrics one surrounding the other to provide a combined variable throw, these eccentrics being normally held against a spring in maximum throw relative positions, and means (e.g. spring urged rollers) being provided to restrain the outer eccentric to a degree depending on the load so as to cause relative rotation of the eccentrics thereby varying the driving ratio.
