With continuous imprint of working load limit.
The roundslings have webbed in stripes for each ton working load limit, one stripe per ton.

Every roundsling is specially impregnated which makes it more resistant against abrasion and dirt.

Supporting element is a high-end PES polyester fibre webbing roundsling endlessly folded. The working load limit grows according to the number of these fibres.  The protective cover of roundslings is made of seamless woven impregnated polyester webbing for endlessly folded fibre webbing.  Long-lasting marking on the protective cover: One woven-in bar for each ton of working load limit and imprinted working load limit on the other side.

Roundsling “DoPremium”

The DoPremium roundsling results from optimizing all available qualities concerning abrasion resistance, widths, tearing resistance, wrinkling tendency, service periods and safety coding.

The roundsling cover of the well- proven DoWeb has been developed even further. The improved webbing design now offers more protection against abrasion and improves handling as the wrinkling tendency has been reduced to a minimum.

According to the standard, a roundsling has to be disposed of if the cover is damaged in such a way that the folded fibres can be seen. Compared to other roundslings the DoPremium quality offers longer service periods as the thickness of the cover can be compared to the one of a web sling.

The DoPremium roundsling has, in addition to the bar code (1 bar for each ton of working load limit), a woven-in working load limit mark. This can smoothly glide over angular loads. The mark can not rot or wear off.

In addition to the compact design, the optimized supporting width under the load and a premium design distinguish these top-rate roundslings. With the new DoPremium, we offer a product which unites all characteristics of a robust and conforming to safety regulations high-value lifting device. It can really be called a “supersling”. New technology for even more safety!

Heavy load roundsling “DoMega”Rundschlinge DoMega Dolezych

We produce heavy load roundslings up to a carrying capcity of 100 tons in all lengths. The advantages for the lifting of heavy loads are obvious: Compared to chains and ropes, a low own weight, especially protecting sensitive goods.

In the higher weight range, DoMega roundslings should be equipped with sharp edge protection if the loads are very angular or if they have sharp edges.

Endless web slings

Dolezych endless web slings (1- or 2-layer) according to DIN EN 1492-1 are perfectly suited for use with traverses in lifting or choking use. Compared to eye slings, endless web slings are much simpler to sew and thus are highly economical lifting devices.

Advantages of endless web slings:

  • easy handling in choking use
  • loads are always acrried ya two strands
  • higher load capacity compared to web slings or stirrup slings of equal width
  • highly cost-efficient

One-way use web slings according to DIN 60005

Einweg-Hebeband nach DIN 60005

One-way use web slings are produced according to DIN 60005 and have a safety factor of 1:5. That means that a sling with a working load limit of 1 t has to reach a breaking load of 5 t. One-use web slings are used for the transport of goods from manufacturer to the customer. They have to be disposed of at the end of the chain of transportation.

Historic situation:

Web slings, especially endless web slings which were not produced in accordance to DIN EN 1492-1 used to be called disposable slings. These slings differing from DIN EN 1492-1 neither did have a colour code nor a standardized, and therefore, unambiguous labelling. They do not meet the minimum thickness prescribed by the industry standard. They were intended for one way-use and supposed to be destroyed afterwards. The safety factor for one-use slings should be 1:5 which is derived from the regulations of BGR 500. In real-life use, these one-use / disposable slings were also used for preslung procedures although they were never intended for this at any rate (see reference to pre-slung procedures on pages 38 and 39). In some opean countries such disposable slings were produced with safety breaking factor 1:4 and even erroneously used for pre-slung procedures in some German enterprises.

DIN 60005:

Because of this DIN 60005 was developed as the new basis for one–way slings.

What does DIN 60005:2005 specify?

  • Safety factor 1:5 is valid, that means that the minimum breaking force must be the working load limit multiplied by 5
  • Minimum thickness of the sling material is 1 mm
  • Maximum band width is 100 mm
  • For unambiguous identification of one-way use, all web slings are equipped with an orange label
  • At the end of the chain of transportation, this means that the one-use web sling must be destroyed

By coming into effect DIN 60005 and a resulting DIN EN in Germany (correspondingly in ope) there is no longer any danger of confusion concerning the carrying load capacities. One-use, or disposable web slings can have very different designs in practical applications, such as endless web slings or eye slings in different colours.

New high-performance fibres revolutionise attachment technology

Modern technology presents new challenges: shipbuilding, with its massive steel giants, or the latest generation of wind power installations, with rotor blades more than 100 metres long, are just two examples of this. It is easy to see that loads are getting larger and heavier, on top of which they must be lifted to greater heights.

Heavy-duty round slings are mostly used for this purpose these days. They have load-carrying capacities of 200 tonnes or more, and are the kings of slinging gears. In this way it is even possible to lift a section of submarine, with a weight of 600 tonnes, securely, as the illustration below shows.

With loading capacities this high, the slinging gear itself can quite easily weigh more than a tonne. Dolezych is therefore making increasing use of new materials, such as high-performance polyethylene fibres, for its high-performance round slings.


“This can reduce the unladen weight of the heavy-duty round slings by up to 70 per cent” says Kersten Krissmann, Heavy Load Project Manager at Dolezych. “This is enormous progress. It is at champions’ league level.”

Modern textile slinging gear has been proven in a wide range of situations – at high temperatures, for instance, or when it is necessary to use a material that is highly resistant to cutting. Aramid yarns, for example, guarantee exceptionally long service lives.

More than 100 patents for your safety

How do products that make life easier for the user actually come into being?

We believe that three factors for success are essential. Firstly, close customer focus. Secondly, experienced, motivated staff. And thirdly, close cooperation of development engineers with universities and technical colleges.

By following this formula for success over the years we have developed more than 100 patents and registered designs that today make lifting and transport even safer.

This includes, for instance, the DoMess 3 mobile tension measuring unit which gives a visual indication of the tension in the lashing strap. So you can assess whether loads are reliably secured. The device has now become part of the standard equipment of anybody who is responsible for load securing – and of the authorities who check these things on the roads.

Lashing straps for wrapping of the Reichstag

For two weeks, the Reichstag in Berlin shimmered in a silver-grey cloak. The shrouding of the old Reichstag building by Christo and Jeanne-Claude between the 24th of June and the 6th of July, 1995, was one of the most spectacular artistic projects in Germany’s post-war history. At 15 million DM, it was also one of the most expensive. The art project drew millions of visitors to Berlin to celebrate the shrouded building.

But whatever was it all about? At least, that was what Udo Dolezych asked himself. Yes, his bid had been successful, and he was actively supporting the art project through the supply of lashing straps. “But what was it all for – that was something I wasn’t clear about at first,” he now grins. “But my wife was determined to get to Berlin to see the wrapping of the Reichstag building from close quarters.”

The Dolezych couple had planned a three-day trip to Berlin – and of course, without missing the chance to include at least one customer visit. But just one walk to the wrapped Reichstag was enough to upend their plans: “I was simply entranced by the sight. We were moved by a sense of celebration, and stood there getting goose-bumps. And the fascinating thing was that I could feel how everyone around me was getting the same feeling.”

Magical attraction

From then on, the Dolezych couple visited the oversize art work up to five times a day. They were able to experience how the silvery envelope around the building changed according to the weather – and how the mood of the visitors changed at the same time: “It was an enormous spectacle – and in the centre was this imposing artistic project with its enormously powerful effect.”

The majority of the visitors can scarcely have been aware of how much work there was behind the wrapping. For weeks, Christo’s team had worked to fasten 109,400 square metres of fabric securely in the specified locations with the help of about 25 kilometres of straps. The gigantic lengths of fabric were held from the outside by highly visible, blue fibre ropes, although the real fastening was hidden in the interior and on the roof. Dolezych had supplied the necessary equipment, the lashing straps and strap tension gauges worth around 150,000 euros. “The backing of our experts and the know-how that was needed was all included,” emphasised the company boss.

Udo and Susanne Dolezych had a chance to see these lashing straps on the second day of their trip. One of the 90 facade climbers who were responsible for the wrapping work took the couple into the Reichstag building, and opened yet more perspectives for them: “The inside of the Reichstag was practically a shell. It was still in ‘wartime condition’. We could still even see the graffiti left on the walls by the Russian soldiers, saying ‘We are the winners’,” recalled Udo Dolezych.

Entire forests of concrete piles and wooden posts had been installed inside the rooms. They were being used as the fixed points for the lashing straps that stretched out through the windows and openings to hold the fabric sheets. “I had another goose-bump moment when I saw ‘Dolezych’ written on all these lashing straps.”

Unexpected perspective

The view from inside to outside held another surprise: the fabric of the shroud, aluminised polypropylene, looks quite opaque from the outside, but from the inside it appeared transparent, like a gauze curtain, offering a soft, veiled view of all the people and the life going on around the monument.

But that was not enough: “We were even able to go onto the roof. Up there, we could not only see our straps and ratchets in use, but we also got a spectacular panoramic view of Berlin, with the Brandenburg gate just in front of us, almost close enough to touch!”

Even today, Udo Dolezych speaks of the Reichstag wrapping as an experience that only comes once: “Unique in one lifetime, and quite unforgettable.”

‚Aus bester Familie’ – book launch in Frankfurt

The second edition of the book “Aus bester Familie” (“From the Best Family”) was launched on 13 October 2011. The publishing arm of the German Standards organisation introduced this reference work in Frankfurt, providing portraits of about 130 successful German family companies, of which Dolezych is one.

The chairman’s son Tim Dolezych, together with the Deputy General Manager Karl-Heinz Keisewitt, accepted the baton as an award for successful family companies.

The book, with its 536 pages, was created on the initiative of commercial consultants Ernst & Young in cooperation with the INTES Academy for Family Companies and the Association of Family Companies, ASU. The publishers are the renowned publisher Dr. Florian Langenscheidt and Prof. Dr. Peter May, founder of INTES.

“The second edition of the book presents about 130 companies that are today successfully being managed by families, explaining their histories and the secrets of their success, and it presents important company personalities and ground-breaking innovations. The book makes an unequivocal plea for entrepreneurial continuity, sustainability and engaged, classic enterprise.” Publisher: Florian Langenscheidt and Peter May

Do.L.O.R.E.S. – the load securing calculation software

In accordance with DIN EN 12195-1 and VDI 2700, sheet 2 Do.L.O.R.E.S. is the load securing calculation software.

Do.L.O.R.E.S stands for ‘Dolezych Ladungssicherung Optimiertes Rechnergestütztes Experten System’ (Dolezych load securing optimised computer-aided expert system). With this software you can determine the necessary number of lashing equipment and their dimensioning with pinpoint precision. Do.L.O.R.E.S. can be used alternatively in assistant mode or in expert mode. The assistant mode offers support in entering the data and is the fastest way to the result. The expert mode offers a large number of input options and also calculates the securing of the load for combinations of different lashing methods.

These are your advantages:

  • the optimised user interface ensures ease of use
  • an extensive help function guides the user step by step through the program
  • there are numerous calculation examples for different loads
  • the arrangement of the load on the loading area can be changed by mouse click
  • DoLores is in German and English; further languages will be available shortly
  • the inputs and results can be stored for subsequent further use
  • there are extensive documentation and printing options for your documents The calculation of the securing of the load takes place in accordance with the valid DIN EN 12195-2. However, calculation parameters according to VDI 2700, sheet 2 can additionally be selected. Supplementary to the European standard, the securing of special loads, e.g. reinforcing steel meshes, is dealt with here.

Towing sling for wheeled vehicles –

The Dolezych towing slings can be used for wheeled vehicles with an approved gross weight of up to 45,000 kg.

These towing slings, which feature an unusually high performance, are made from high-strength polyester. They are easy to handle, thanks to their low unladen weight.

Eye slings

Dolezych eye slings are lightweight and handy. The eyes are reinforced by coloured abrasion-resistant woven material. The eye reinforcement does not swell up when wet: that is why we do not use leather. For 1-4 layer web slings we differentiate between two differently sewn types of eyes that have shown their efficiency in practice: For multi layer web slings the flat eye is standard. They are available in standard reinforcement and full reinforcement. Single layer stirrup slings are produced with a 90° turned “inversed eye” (type C + D). They are available in standard reinforcement and full reinforcement.

Table eye widths and eye types

In the table to the right, you will find an overview of all available and technically possible eye widths and eye types. Depending on the width of the eye sling firstly, you have the choice between eye widths which have either full, half, or one-third width of the web sling.
You also have the choice of eye type:

  • standard reinforcement (type A)
  • full reinforcement (type B)
  • inversed eye (type C) normal reinforcement
  • inversed eye, full reinforcement (type D)

Upon request, we also produce web sling eyes in special dimensions and with special reinforcements adjusted to your special crane hook.
