Description

"Load handling equipment, primarily for precast concrete parts"

The hiring concerns a. Load suspension devices, primarily for precast concrete parts.

For this purpose, rope slings with two loops are known from which one loop is intended for hanging in a crane hook and in the other, smaller and useful with a thimble stiffened loop, an eyebolt or the like is held, which is in a precast concrete part recessed anchor is releasably einsehraubbar.

With such load handling devices, however, the crane hook loops wear out premature than the eyebolt loops · This is due to the many bending cycles involving from case to pail often different and small bending radius around the crane hook, supported by the requirement that the crane hook loop must also be dimensioned relatively large for easy hanging in a crane hook.

Stiffening the crane hook loop as well as the ring screw loop with a thimble did not lead to one Increasing the service life of the crane hook loop. Much more

m 2

Such thimbles break, due to their considerably larger radii of curvature than crane hooks, after just a few loads and the sharp edges of the break points "favor an even faster wear of the crane hook rope loop ·

The aim of the fire is now a load handling device, primarily for precast concrete parts, consisting of a wire rope with two loops arranged one behind the other, one of which is used for It is intended to be hung in a crane hook or the like and the other, smaller loop, by an eyebolt or the like, and preferably further stiffened the ring screw loop by means of a suitable thimble whose crane hook loop has at least the same service life as the eye bolt loop, without the size of the To reduce the crane hook loop and its flexibility and without significantly increasing the dead weight of the load suspension device raise.

The solution to this problem is essentially characterized by the fact that the crane hook loop has two load-bearing rope strands at least in the area of the bend _$ whereby the wire rope diameter of each rope strand of the crane hook loop preferably corresponds to the wire rope diameter of the ring screw loop.

For this purpose, an advantageous and inventive one is characterized Embodiment in that the crane hook loop consists of two rope loops arranged next to one another.

A preferred and inventive embodiment of the above The object is characterized in that two of the same length from the root of the ring screw loop or strive almost equally long rope strands and each rope strand after forming a handle in the area of its end is connected to the other rope strand »

Finally, an advantageous and inventive feature of the prescribed subject matter is characterized in that that soft metal compression sleeves serve as rope connections *

In the drawing, an embodiment of the subject of price increase is shown and is described in more detail below.

It show: IUg. 1 a load suspension device in the front view, Sig 2 the same in the side view

Here, a wire rope is formed into a loop 1 approximately in the middle of its longitudinal extension. The latter is bounded at the top by a soft metal compression sleeve 2 and further stiffened by a thimble »From the loop 1 strive upwards to form a crane hook loop 4, two cable strands 5 and 5 ^{1 of} approximately the same length, both of which form a handle 6 and 6 'and in the area their ends are attached to the other rope strand by means of a soft metal compression sleeve 2. An eyebolt 7 is held in loop 1

Instead of the eye bolt 7, an eye nut can of course also be provided.
