Abstract
A device (10) for manipulating submerged-operating units (11), such as submersible motor-driven pumps, submersible motor-driven stirrers and the like, has a hoist, by means of which the unit (11) can be brought into a submerged working position and a surfaced maintenance position, wherein the unit (11) is provided with a lifting strap (25) of a coupling unit, whose coupling element (60, 60'), which can be brought into and out of engagement with the lifting strap (25), is provided on a pulling element (48) of the hoist. In order to be able to design the device for manipulating submerged-operating units mechanically more simply and to use it also without a guide device, it is provided that the coupling element is formed from a first bridge-like drop bar (60) for lowering the unit (11), or a second bridge-like drop bar (60') for lifting the unit (11), on which the lifting strap (25) rests during the lowering or raising of the unit (11), and that in the unstressed state the first drop bar (60) automatically takes up its opening position, and the second drop bar (60') automatically takes up its closed position.
