DE102007044706A1 - Textile sling band, has coatings formed in stop and rear sides of textile base band respectively in positive material fit manner, where coating contains plastic, which is colored according to load-carrying capacity of base band - Google Patents

Abstract

The band has coatings (6, 7) formed in stop and rear sides (2, 3) of a textile base band (1) respectively in a positive material fit manner. The coating contains plastic, which is colored according to a load-carrying capacity of the base band, where violet color corresponds to the load-carrying capacity of 1 tonne, green color corresponds to the load-carrying capacity of 2 tonne, yellow color corresponds to the load-carrying capacity of 3 tonne, grey color corresponds to the load-carrying capacity of 4 tonne and red color corresponds to the load-carrying capacity of 5 tonne. An independent claim is also included for a method for manufacturing a sling band.

Description

The invention relates to a lifting belt and a method for producing a lifting belt. Lifting straps are, as in the German utility model DE 295 09 126 U1 or in the norm EN 1492-1 described, made of a textile fabric and serve to lift by means of mechanical lifting heavy goods. For this purpose, the lifting straps are placed around the loads and attached to the hoist.

To protect lifting straps from damage, they are usually covered by a protective layer. The protective layer is usually made of a plastic that surrounds the textile lifting strap or covers on one side. For this purpose, the plastic protective layer is sewn or firmly applied or pushed over as a separate tube. Textile tapes are made according to the norm EN 1492-1 dyed according to their load capacity, so z. For example, a lifting belt with a lifting capacity of 4.0 tonnes is gray and one with a lifting capacity of 8.0 tonnes is blue.

at firmly applied protective coatings, for example made of polyurethane the problem arises that the protective coating only on white, d. H. undyed, bands expertly can be applied. Thus, that is missing after the above EN standard prescribed color coding. It is currently with it get the lifting straps with corresponding colored loop reinforcements whereby the user, the so-called the lifting straps this code is not used and only rarely noticed.

It is therefore an object of the present invention, a textile lifting strap specify its carrying capacity permanently and over the entire length of the lifting strap is better recognized. moreover It is an object of the invention to provide a method for producing a to provide such lifting bands.

These The object is achieved by the subject matter of the independent claims solved. Advantageous embodiments will be apparent from the respective subclaims.

It is therefore a lifting strap with a stop side and one of Stop side opposite rear provided. The stop side is the side facing the load. The Lifting tape has at least one textile baseband with a cohesive Coating on. The coating contains a polyurethane, that according to the load-bearing capacity of the textile baseband is colored. The lifting strap is preferably made of polyester, Polyamide or polypropylene.

The Coating is preferably a single-sided polyurethane or two-sided emulsion coating in one thickness from standard 0.1 mm to 0.2 mm.

These special coloring makes it possible to get the required Color coding to detect the load capacity of the lifting gear over a large area for the user in the usual way the entire length of the band, safe and wear-free to design.

For this purpose, preferably the plastic according to the European standard EN 1492-1 dyed, which allows a fast and above all safe detection of the carrying capacity.

In an embodiment is on a first side of the lifting belt, the stop side, a first coating applied to the o. g. Contains plastic and on the opposite Back will be a second coating, which also has this Contains plastic, applied. The plastic in the second coating will be according to the load capacity dyed the baseband. On the back side The plastic can by staining in its physical Properties are changed without it's function of the sling impaired while on the Stop side, the coating is particularly similar for all lifting straps should be.

at the first coating is preferably at least one 5 mm thick hard coat, while the second coat an emulsion coating with a thickness of 0.1 mm to 0.2 mm.

The Invention also relates to a method for producing a lifting belt, in which first a textile baseband is produced and then the base tape is coated with a coating, which contains a plastic. Here is the plastic dyed according to the carrying capacity of the baseband. It is preferably used as plastic polyurethene, a Material that stands out for its high wear resistance distinguished.

Becomes sprayed on the coating, this is particularly uniform, so that the lifting strap is essentially equally good everywhere protected against abrasion.

At the Spreading the coating, on the other hand, gives a special effect good adhesion to the baseband, so that the abrasion protection is particularly durable is.

The The invention is illustrated in the drawing with reference to an embodiment illustrated in more detail.

1 shows an inventive lifting strap in cross section. The lifting strap contains a baseband 1 made of a textile material and is folded together so that there is a two-ply band in the middle and a right crane loop at both ends 4 and a left crane loop 5 formed. The lifting strap has a stop side 5 and a back 3 on. The right crane loop 4 and the left crane loop 5 are usually hooked together in a hook so that the load to be lifted on the lifting strap on the stop side 6 rests.

The stop side 5 has a first coating 6 on, which serves to protect against sharp edges. The first coating 6 contains polyurethane and is about 5 mm thick. It is applied by means of a casting process on the baseband. For this, the baseband is clamped and coated with a liquid containing polyurethane. Polyurethane is a material that is characterized by its high wear and cut resistance.

In contrast, the second coating is used 7 on the back side 3 as protection against wear due to abrasion. It is only 0.1 to 0.12 mm thick and also contains polyurethane, which corresponds to the carrying capacity of the baseband 1 is colored. For a lifting strap with the carrying capacity of z. B. 2 tons is the polyurethane of the second coating 7 dyed green. In contrast, the first coating 6 not colored. The second coating 7 For example, it is sprayed or painted on.

In a further embodiment, the first coating becomes 6 like the second coating 7 designed as abrasion protection and dyed accordingly.

The colors are made according to the European standard EN 1492-1 allocated so that the color violet corresponds to a carrying capacity of 1 t, the color green to a carrying capacity of 2 t, the color yellow to a carrying capacity of 3 t, the color gray to a carrying capacity of 4 t, the color red to a carrying capacity of 5 t, the color brown has a load-bearing capacity of 6 t, the color blue corresponds to a load-bearing capacity of 8 t and the color orange corresponds to a load-bearing capacity of greater than or equal to 10 t.
