摘要

The device has a lifting unit with a hoist rope (4) and a storage drum (5) with another hoist rope (7), which are particularly arranged on a floating unit (21). A lifting unit frame (13) is provided, which is attached on the former hoist rope, whose buoyancy in water is variably controlled. The buoyancy of the lifting unit frame is an overpressure lifting unit frame, which comprises an air reservoir, where the buoyancy of the overpressure lifting unit frame in the water is variably adjusted. An independent claim is included for a method for lifting and lowering of a load in water.
