DoLast lifts!

300 Tons on a crossbeam

A huge coke-processing machine – a so-called filling car – is to be shipped as a whole via Brussels to Marseille. The task for us in Dortmund: to construct a lifting beam that can lift the filling car, which is approximately the size of a small house and weighs about 300 tons.

Our designers were happy to accept this challenge. The crossbeam is just as impressive in size as the machine being lifted. We were on site for the test lift: Within one morning, the spreader beam was attached, the gigantic load was lifted and it performed its service: Smoothly and reliably – test lift successful! We accompanied the exciting scene photographically:

Perfect connection between textile DoNova® chain and DoRa tensioner

Perfect connection between textile DoNova® chain and DoRa tensioner

For proper load securing you must secure with ratchet load tensioners and lashing chains, among other things. The faster and easier this can be done, the better for employees and nerves.

As is so often the case, the devil is in the details. This detail to the popular textile lashing chain DoNova® and the innovative ratchet load tensioner DoRa was developed by our engineers in Dortmund: The specially adapted DoRa hook now securely connects the DoRa telescopic tensioner to the DoNova® lashing chain. This allows you to enjoy all the advantages of the super-light textile chain and the DoRa tensioner in its minimal design with maximum tensioning travel at the same time – efficient and flexible working is then guaranteed!

Is that safe? – From practice to the test laboratory

Is that safe? – From practice to the test laboratory

We have tested makeshift applications of lashing hook connections for their safety

If you want to bundle loads safely one-piece belts are usually used. However, if the length of the available one-piece tiedown straps is not sufficient for this purpose or if none are available at all two-piece tiedown straps are often used. For bundling their profile hooks are then hooked into each other. Tiedown straps extended or connected in this way are not uncommon in European road traffic. But does this still conform to standards?

Standards and directives do not clearly define whether and which hook connections are permissible. They merely stipulate that hooks may be loaded with tensile stress but not with bending stress. At first glance this is probably not guaranteed for many of the improvised hook connections. So far, however, there are no published tests on the subject. So are such connections safe or not? Our technical team was curious and investigated this question together with Konrad Rainer from the Austrian expert office Cargo Safetytec in the Dolezych Germany test laboratory. The answers that emerged are impressive

Best possible test conditions

The test specimens were profile hooks (often referred to as pointed hooks), which are commonly used as connections of tiedown straps to lashing points or on outer frame hole profiles on the vehicle. On our certified testing machines of accuracy class 1, we tested test arrangements according to Figures 1 – 4.

For the tests we selected exclusively new unused and welded quality hooks of the same type from Dolezych. “We deliberately refrained from combining different hook types from different manufacturers because otherwise we would have had to consider additional influences that we wanted to exclude in our tests” explains Uwe Schöbel, Head of the Technology Department.

Tests expose weak connections

The result of the tests is clear: Most of the tested lashing hook connection methods are not safe! “The majority of the hook combinations did not even survive the load test prescribed in the DIN EN 12195-2 standard. This states that a lashing hook must withstand a load of more than 25% of its WLL without deformation or malfunction” says our test engineer Winfried Röhn. “In the subsequent tensile test, which is also required by the standard almost all the hook connections also failed. In this case the hooks should actually be able to be loaded with twice their WLL and survive this without breaking.” In some Tests the hooks broke (Figs. 2 and 4). Other hook connections such as the one in Fig. 1, were already unacceptably bent up after the test loads. The only combination that survived all tests was the method of hooks symmetrically hooked into each other in the hook head (Fig. 3).

Impressive conclusion

Our tests thus show impressively: as soon as hooks are improperly connected and loaded for bending in the process they are no longer safe. The marked WLL is no longer achieved. This can have devastating consequences. Such improvised hook connections can fail in practical use and must therefore never be used! Only the variant symmetrically hooked into each other in the hook head (Fig.3) achieved the required strength in our tests. “If the lashing hooks are identical types that meet all normative requirements, this connection is perfectly possible in practical use,” Uwe Schöbel sums up. Therefore, our urgent advice: Avoid risky improvisation! It is best to ensure the correct load securing in each case by using a suitable selection of lashing equipment. This includes, for example, strapping lashings in sufficient lengths or two-part systems with special lashing hooks.

The DoNova® PowerLash textile chain could also help. It is the flexible all-rounder” (more information on its many possible applications can be found for example at www.donova.info).

A lashing strap with a difference

A lashing strap with a difference

Typically lashing straps are used to tie down and secure cargo. But sometimes unconventional ways also lead to a goal.

Creativity in maintenance

One of our customers for example got creative to find a simple and effective securing measure for the maintenance of forklift trucks. In the process their protective hoods have to be held up. In the past this led to problems. In the lead role in this solution: a lashing strap. Previously the protective hood had only been “supported” with wooden beams – a very error-prone design as the beams tipped away even when touched lightly and could no longer hold the hood in place. The result was bruising and other injuries to the employees’ hands.

The magic word is “flexible

The customer’s occupational safety department therefore had to quickly develop a flexible and robust solution. The safety officers took 2,000 daN lashing straps attached their S-hooks to the protective hood passed the 35 mm webbing once over the roof of the vehicle – and perfect strapping was ready just like for load securing. Because the ratchet allows the strap length to be flexibly adjusted this solution can also be used with forklift protective hoods of different sizes. A lashing strap with a difference but used very cleverly!

Eight meters of lashing chain simply thrown loosely over the left shoulder at the same time six meters casually in the right hand – and this by our petite colleague Halina Kampa from the test room.

Of course this only works with our textile lashing chain DoNova® PowerLash whose individual chain links in the version with 25 mm width and 8 layers of webbing only weigh about 60 grams. At the same time it is extremely robust and secures loads with an LC of 10,000 daN – which is comparable to a heavy 13 mm steel chain of grade 8. Even stronger DoNova® systems even reach an LC of 20,000 daN – just like 16 mm steel chains of grade 10.

We were allowed to equip ten truck rear doors of a Dolezych Germany customer with this great picture and are very proud that these trailers with our motif are now on the roads of Europe. Maybe you will discover one of these vehicles one day!

Exclusive cooperation in the name of safety

BPW iGurt with Dolezych lashing strap available now

How much they have to tighten their lashing straps in order to secure the load sufficiently is often estimated by many users on the basis of their feeling, sense of proportion and, in some cases, years of experience. However, this approach is often inadequate. Too little pretensioning force in the lashing equipment (slipping load) or a too tight lashing can often result in costly and dangerous damage to the goods being transported or the load itself.

In order to give the user more security in this respect, Dolezych has for many years offered products that can indicate the pretensioning force achieved in each case, e.g. mobile pretensioning force measuring devices from the Dolezych “DoMess” product range.

Intelligent cargo restraint

For the same reasons, BPW Bergische Achsen KG has developed the iGurt, which has already won the Golden German Innovation Award in the category “Excellence in Business to Business – Automotive Technologies” of the German Design Council in May 2019. The iGurt is an intelligent pretensioning force indicator that continuously monitors the pretensioning force on the lashing strap via app.

Common configuration

To ensure that the iGurt indicator functions optimally, it is matched to a special Dolezych lashing strap. The final combination of iGurt and lashing strap was thus created through cooperation between the two German quality manufacturers BPW and Dolezych Germany. “Together, the entire system was developed and configured. The iGurt is now available exclusively with Dolezych lashing straps,” reports Uwe Schöbel, head of the Dolezych Germany technical department.

Cargo restraint continuously in view

The functionality of the handy and robust pretensioning force indicator is delightfully simple. It is easily and quickly attached to the lashing strap by means of a clip mechanism. Already during tensioning, the iGurt shows in 50 daN increments the indication value of the measured pretensioning forces. If the pretensioning force falls below its previously set minimum value, e.g. while driving, the user is minimum value, the user – this can be the driver, but also a forwarder – is informed of this via a message in his smartphone app (Android) about this. The user can correct the cargo restraint on the lashing strap in question. “So he doesn’t have to check each lashing strap individually to find out where the loss occurred. This saves time and he can quickly continue the journey safely,” explains Sales Manager Walter Eckstein one of the main benefits of the safety system.

Transparency, less damage, lower costs

The advantages are obvious: more transparency and reduced downtimes, a verifiable loading control as well as fewer accidents and damage due to inadequately secured or cargo that has been tied down too tightly. This also results in less effort for claims processing in the company. “So the iGurt will play its contribute to the protection of people and loads in road traffic. It will also help to save considerable costs,” says Walter Eckstein. The product innovation, which is eligible for funding under the “De-minimis program” of the German government, is available now exclusively in the BPW store telematics24.de and in the Dolezych Germany online store (shipping to Germany and Austria).

JP Performance as a guest of Dolezych

“Dollitschech?” – “No, Dolezych.” responds Tim Dolezych with a laugh to JP’s question about the correct pronunciation of the company name. A very entertaining back-and-forth develops on this topic, which you can watch in the video “JP Performance – Road Trip to the Porsche Doc | Porsche 964 Turbo” on JP Performance’s YouTube channel. JP is – like Dolezych – at home in Dortmund and stands like no other for the topics car and professional tuning.

The focus of the clip which lasts about half an hour is a Porsche 964 Turbo engine that is to be transported from Dortmund to Rimbach in Bavaria for repairs – but it goes without saying that the load must first be properly secured. But how is it actually ensured that load securing equipment such as lashing straps actually achieve the performance promised on the label? And how does a lashing strap test actually work? JP personally picked up the answers to these questions in our test room.

Find out in the video whether the valuable load can ultimately be transported to its destination and back without damage. One thing’s for sure: The pronunciation of “Dolezych” is at least clear in the end.

85 years Dolezych – An interview with Udo & Tim Dolezych

85 years Dolezych – An interview with Udo & Tim Dolezych (Owner family of Dolezych Group)

You both took over the management of the company from your fathers. Was that a matter of course for you or did you originally plan something else?

Udo Dolezych: That was already clear during my school days. That’s why I studied business administration in order to be prepared for my future role in the company. If I had known at that time how much technology was connected with our products, I would have added a technical degree. I then learned this through practical experience. But I envy Tim a little for his engineer… (laughs)

Tim Dolezych: With me it was similar to my father. When I studied economics at the latest, it was clear to me that I too wanted to join the company.

In your opinion, what were the decisive milestones in Dolezych’s this year 85-year history?

Udo Dolezych: Certainly the introduction of textile products at the end of the 1970s, which made us a full-range supplier of lifting and lashing equipment – since the mid-1980s also including service offers such as testing service, maintenance and seminars. Another important step was the opening of our Polish branch in Katowice in 1992, which heralded the internationalization of Dolezych. Of course, it was always challenging and decisive to develop our company technically, for example by further developing IT or by converting to automated production processes.

What was the most exciting project at Dolezych that you were able to accompany?

Udo Dolezych: The company foundations in Poland, China and Chile That was an extremely interesting and exciting time in which I learned a lot.

Tim Dolezych: In addition to founding the company in the USA, I am particularly fascinated by the current projects related to digitization because I know that we are actively setting the course for our future here.

You have recently reformulated the company’s philosophy (see our website www.dolezych.de). How does the current version differ from the old one?

Tim Dolezych: We have been working hard recently to formulate our brand core and corporate identity. The newly formulated philosophy reflects both aspects much more precisely. In addition, in line with our mission and vision, it emphasizes that customer benefit is the focus of our daily activities – this focus was particularly important to us.

How does the characteristic “family business” express itself concretely in Dolezych’s case?

Udo Dolezych: The employees see that we as a family stand behind them and the company. The decision-making paths are short, our doors are always open and there is a lot of freedom to make decisions. All in all, things here are very personal – in contrast to a corporate group, where the individual tends to remain anonymous. This trust is returned to us by the employees, who in turn stand loyally behind the company.

Price competition on the market has become fiercer, especially in recent years. Even products of inferior quality are irritating the industry. At the end of 2018, for example, the Fachverband Seile und Anschlagmittel e. V. (Association of Ropes and Slings) discovered serious defects in lashing belts – even in belts with the GS mark. What strategies are you using to counter these developments?

Tim Dolezych: Yes, it is indeed a great challenge. Unfortunately, the low-priced products are often of inferior quality.

Udo Dolezych: In addition, fraudulent labelling sometimes leads to healthy apples being confused with rotten apples – to put it quite metaphorically. The poor quality is often not apparent to the customer because the products’ quality characteristics such as breaking strength, load-bearing capacity, abrasion resistance, etc. and thus their functional reliability are not apparent. They can only be determined with the help of complex tests and QA measures. We have to inform regularly about the effort we put into this and thus strengthen the confidence in our quality products.

Tim Dolezych: In addition, from our point of view it remains important to be an innovation driver – in other words, to do what companies with less technical expertise cannot do. To do this, we also need highly trained personnel to offer our customers the greatest possible benefit.

What other challenges await Dolezych in the coming years?

Udo Dolezych: I think the continuous task remains to manoeuvre the company through times of an unsettled global economy. The customs dispute between the USA and China or the corona virus are just two examples of current developments to which we must find the right answers for our business. Such challenges are unlikely to diminish in the coming years.

Tim Dolezych: I think it will also be about dealing with digital progress and creating new opportunities for us. We will all have to educate ourselves in completely new areas like AI. Intelligent products, for example for autonomous driving, offer exciting tasks. It will be important to approach any topic openly, solution-oriented and with energy.

As a complete supplier of lifting and load securing solutions, Dolezych has a very broad target group. Where do you see further potential and in which areas do you want to grow even more in the future?

Tim Dolezych: We would like to continue to strengthen the retail trade in the future, for example through innovations. And large industrial end users also need a high-quality production and consulting program. This is where we are in demand as a specialist to make the customer’s work safer and easier.

A nice closing. Thank you very much for your time!
