Tensioning device, in particular for seaworthy lashing of cargo on board Ships

The innovation relates to a clamping device with a Screw connection to be operated by handwheel, as is particularly the case with marine lashing of cargo (Container) is used on board ships.

It is known to use these screw connections Provide tensioning attachments with firmly attached handwheels with which the tensioning screws by hand have a certain degree Amount can be stretched.

Such fixed handwheels for actuation, however, have numerous pike spots. First of all, need the clamping screws because of the relatively large handwheel

diameter a considerable space for storage Disuse, which is much greater than that for handwheelless clamping screws required storage space. In many cases, the tensioning screws remain, for example Folded at their lower end, at the respective place of use, i.e. they are removed when not in use placed horizontally on the ship's deck or hatch cover. If there are fixed handwheels this stowage possibility is made very difficult, as the handwheel has a flawless operation due to its relatively large duration Lying of the clamping screw obstructed or even makes completely impossible.

The aim of the present hiring is therefore the jigs dor initially mentioned type so that they take advantage of the easy-to-operate Maintain screw connection, but do not have the disadvantages described above.

In order to solve the aforementioned problem, the innovation is proposed that the handwheel be easily detachable and detachable on aein au actuating part of the screw connection to arrange. Here, a non-rotatably engaging plug-on coupling is preferably provided, one of which Half on the circumference of the part of the screw to be operated

Connect and eat the other half in the vicinity of the

Due to the training according to the innovation will not only the aforementioned disadvantages are eliminated, but there is also the advantage that not for Each tensioning screw needs its own handwheel, but you can use one for several tensioning screws Use the handwheel.

Veit *? «Details and characteristics of the innovation result can be derived from the following detailed description and the accompanying drawing, in "-ar» evsugte embodiments of the innovation are illustrated, for example.

In the drawing see: Fig. 1 is a partially sectioned schematic Side view of a clamping screw according to FIG

The clamping devices shown in the drawings consist of an internally threaded clamping sleeve 1 into which the externally threaded end screwed into a threaded spindle. This threaded spindle is made with the means shown in more detail held non-rotatably when actuated. A swivel hook is mounted in the clamping sleeve 1.
