Securing the hinge mechanism, a damping cylinder 11 is provided, which is connected to the second joint member 10 b and the movable support 6. For example, if a later described rope tears, with which the pivotal movement is performed, the cushioning cylinder will cause the ceiling formwork element to gently return to the inclined orientation. Thus, the damping cylinder contributes to Ii

Safety in handling the lifting and pivoting device 1 at.

At the base 7, a handle bar 5 is attached to one end of the lifting and pivoting device 1, where also the

Operating area 100 is located. In the operating area 100, a first winch 3 is provided for vertically exposing the movable support 6, for example by means of a cable relative to the base 7, and a second winch 4 for actuating the pivoting unit 2. For the latter actuation, a cable 12 on which the hinge elements 10a, 10b connecting joint 10c attached, and deflected over an upper portion of the movable support.

Ceiling formwork element D possible.

The stripping, a slab formwork element D using the device according to the invention is possible in reverse order. This means that the supports, which are opposite to the pivot axis, can either be removed or placed in a relation to the slab formwork element D pivotable state. Subsequently, the slab formwork element D is pivoted by means of the lifting and pivoting device 1 with respect to the still standing supports, and subsequently

lowered. Optionally, the supports, which are opposite to the pivot axis, not only in one stripping

be brought pivotable state, but the supports can already be brought before the pivoting of the slab formwork element D by means of the lifting and pivoting device 1 manually or by means of another device in an inclined orientation. Here, the lifting and pivoting device 1 supports the slab formwork element D.

Alierdings are in other objectives of the present invention also different locking options
