Whether it is the handling of coal and iron ore or the loading and unloading of grain, animal feed, scrap metal, minerals, biomass or other bulk goods, Nemag ensures that the work will get done as efficiently as possible. All Nemag products are made in close consultation with clients, in order to guarantee that their needs are met. That is why Nemag’s grabs have such a strong reputation around the world.
The company is particularly focusing on the design and manufacture of high end bulk handlings grabs.
Its customers are large-scale bulk handling companies, steel plants and coal-fired power stations that handle very large quantities of bulk such as coal and iron ore.
These customers all share the same high berth occupancy degree, combined with the fact that they use relatively small quantities of grabs to handle huge tonnages of cargo.
Nemag has experienced a continuing demand during the last year, with numerous new opportunities for the near future and that is reflected in its order book.
Especially in the economic difficult market of recent years, all Nemag’s clients are forced to investigate the return on all their investments, including the grabs. The most important aspect in this respect is the running cost of an installation and its equipment. The reason many big stevedoring companies choose to operate a Nemag grab is because it ensures the lowest maintenance cost per tonne against the highest productivity.
Says Riny Stoutjesdijk, sales manager at Nemag, “When using this kind of equipment, it is of paramount importance to realize that investment cost of a grab is of relative small importance compared to the total life cycle costs; every experienced stevedoring company knows that.”
Nemag spends a lot of time on research and development. Together with its customers, research institutes and universities, Nemag continuously works on technological improvements and refinements. The company investigates new materials, experiments with new types of grabs to increase efficiency for unloading cargo and to lowering the costs per transshipped tonne.
“Furthermore, we are always looking for ways to meet the increasingly strict environmental regulations.This way, we help our client to fulfill their responsibility toward the environment”, says Stoutjesdijk.“We design products customized to the client’s wishes, to enable the balanced and economically optimized handling of his specific goods. Naturally, this is based on technical concepts that have proven their value in practice.This is why the Nemag approach appeals to clients.”
And this appeal is shown by the numerous contracts Nemag has been awarded with, both in- and outside Europe.
Nemag recently delivered huge 80- tonne SWL scissors grabs to Konecranes destined for Nippon Steel Corporation in Japan, as well as various clamshell grabs for UK-based Associated British Ports (ABP) and for the new ZPMC ship-unloaders of Vale, Praia Mole, at Vitoria, Brazil.
Also existing Nemag customers have opted for Nemag grabs again this year, at various locations of TataSteel, as well as new customer, Rietlanden Terminals in Amsterdam, which placed repetitive orders for new environmentally friendly Nemag
clamshell grabs for handling steam coal. Furthermore, Nemag started co-operation with Delft
University recently and is investing in ground breaking development of new simulation software to create rapid prototyping of grabs: this will accelerate development of existing and possibly new grab designs, which will contribute further to Nemag's slogan "Designing grabs which result in the lowest costs per tonne material transferred".
KRO¨GER: making its grabs in Germany
MANUFACTURER CELEBRATES 50TH ANNIVERSARY OF FOUNDING – SUCCESS ON THE ASIAN MARKET
In the world’s harbours, international waste processing facilities and in local gravel pits; wherever the best materials and technologies are required, you’ll find KRO¨GER grabs at work. For over 50 years, this German company has only ever used a combination of quality and high-tech. Its numerous innovations and completely maintenance-free products have made the company one of the market leaders in many different countries.
Above all, KRO¨GER has achieved recognition through its hydraulic grabs. This model is increasingly in demand in inland harbours and sea ports. Recently, the principle of maintenance- free technology has become a trademark of KRO¨GER and its large grabs. This selling point is unique in the world. In Turkey, India or Eastern Europe: whenever large goods transfer machines or mobile cranes are used, you will find that they are increasingly being fitted with two or more bucket grips like the models KZH and KMH made in Germany.
Whilst transfer sites for bulk goods, waste processing sites and gravel pits make up KRO¨GER’s traditional business, the company has also recently broken into a new market: the very large area of fuel surrogates. Unbreakable grabs are also needed in this area too — and KRO¨GER can deliver — no matter whether you need two or more fold grabs. The combination of high flexibility and first class service and warranty terms is also a product of the company’s decades of experience.
The foundations for global success were laid down as early as 1962, when Werner Kro¨ger founded his machine plant in Sonsbeck. Eleven years later the first grabs were produced. The company focused on two and four cable grabs for the construction industry and OEMs. Just five years later came the next coup: in 1975 KRO¨GER began producing cable grabs for gravel and sand extraction underwater. This specialist equipment was not only extremely efficient but was constantly improved over the course of time. It’s no coincidence that KRO¨GER products set new depth records time and again. Current example: with an underwater cable grab, model UWS, from KRO¨GER, which has a volume of 8m3, a 26-tonne rock was extracted from Lake Lucerne (Switzerland) at a depth of 180m!
The company can thank the business foresight of its founder for its ability to quickly acquire new areas of the market for its grabs. As early as 1977, KRO¨GER delivered its first grabs for harbour and industry transfer. A quantum leap took place four years later providing the basis for global success: the company presented the first maintenance-free cable grab.
The stormy developments in the Lower Rhine were carefully followed by the markets. In order to guarantee solid, international development over the long-term, the Kro¨ger family decided to acquire the former Ruhkohle AG (today Evonik) in 1988. What no one could know back then was that group affiliation would not last. As
early as 1993, KRO¨GER became an independent company once more. The next innovation came in the same year: in the factory the first cable, motor-powered and hydraulic grabs were produced for the waste and slag disposal industries.
One of KRO¨GER’s trademark characteristics has always been a high degree of independence, which was required to establish new developments on international markets. This principle remained unaltered by the paradigm shift that took place within the company in 2008. The management decided to sell a share of the company to Elbe Partners Industries GmbH, Hamburg. This decision provided new money for further development of the company and to reinforce old strengths. KRO¨GER, which principally produces custom- made and, generally, maintenance-free large grabs was integrated within Elbe Industrietechnik GmbH just one year after the change of ownership. This medium-sized industrial group, with its sister companies FMS Fra¨nkischer Maschinen- und Stahlbau (Gochsheim, Bayern) and Oswald Metzen (Bitburg, Germany), rests on the private shareholder structure of Elbe Partners and guarantees sustainable, financial stability. This allows synergy potentials within the group to be utilized and mutual customers and markets to be served whilst retaining the independence of the individual companies.
Strengthened, KRO¨GER continued to lengthen the list of its records. In 2011, the world’s largest floating digger stationed near Freiburg in South Germany was fitted with a gigantic and above all maintenance-free underwater 12002 UWS-7 grab. This conversion increased the digger’s volume capacity from 7.5 to 13.5m3 with the result that now 27 tonnes of material could be extracted with every lift sequence.
Of course, the reason behind the fitting of the new grab was not to break records but to increase efficiency. Due to the increasing depths at which the gravel industry is working, the trend towards significantly larger systems with very high grab volumes is growing. This combination is the only real option that ensures efficient extraction over the long-term. KRO¨GER has been able to not only fulfil these new demands with respect to underwater cable grabs but also with hydraulic and motor-driven, underwater grabs. With a volume capacity of 12m3, KRO¨GER currently supplies the largest equipment parts within this sector in Europe. These grabs from Germany also allow depths far in excess of 100 metres to be worked even under very difficult conditions at the bottom.
These are just some of the many, spectacular examples that KRO¨GER has been able to
deliver over the past few years. All the signs also point towards growth in the future. Just recently, DEMAG Cranes ordered 19 refuse grabs for use in China and Finland. Contracts for waste incineration plants and gravel extraction were also concluded with the globally-active crane manufacturer KW Mannheim. KRO¨GER is also an original equipment manufacturer for the German crane manufacturer Sennebogen and has supplied large grabs with volume capacities of 25m3 for its Greene Line and Crane Line models. It is clear that KRO¨GER’s principle of maintenance-free and permanently greased grabs is becoming increasingly popular — even in harbours in Turkey and India, where motor and hydraulic grabs are particularly popular.

Akerbergs grabs, lowest price does not equal lowest cost
Akerbergs is a Danish company with more than 30 years of experience in sales, service and maintenance of all kinds of cranes and port equipment, but especially mobile harbour cranes in the Scandinavian market. For new sales Akerbergs today works in close cooperation with Liebherr, producer of mobile harbour cranes and material handling equipment, and Akerbergs is its representative in Finland, Norway, Sweden and Denmark.
But regardless of what kind of crane one is talking about, it can never do any work without some kind of auxiliary equipment. In the simplest form, the hook for simple lifting purposes, or more advanced, a container spreader or a grab for handling of bulk material. Before, many people just looked into what kind of material they should handle, for example: A clamshell grab for handling coal, grain, wood pellets and so on, or a poly grab or ‘orange peel’ grab for handling iron scrap, pig iron and similar.
Today however, everybody is looking for more and more efficiency and therefore the cranes with grabs becomes bigger and bigger, enabling one man to handle more and more
material within the hour. So today we see grabs of 60m3 capacity or more attached to harbour mobile cranes. Such a grab has the size of a bus and the weight is more or less the same! This weight has to be hoisted every single time the crane makes a lift regardless if the grab is empty or full and therefore it has become increasingly necessary to have a grab design with high volume and at the same time low weight, without compromising the strength of the grab. And at the same time it is very essential that the grab has a good digging ability to ensure that the grab is as full as possible each time it digs into the cargo. In that way the crane can perform a higher payload for each cycle and in the end a bigger capacity.
Akerbergs has through the years worked with different grab suppliers with great success, but in a more and more demanding market the company three years ago chose to work with Verstegen, which has been in the market for more than 60 years.
During this period Verstegen has developed and refined the design of its grabs to become one of the absolute best suppliers of four-rope grabs in the world. By using steel with a high amount of hardness, as well as extreme toughness,Verstegen has been able to use less material in constructing its grabs and thereby achieved having a light weight product, without compromising quality and lifetime of the grabs.
It is clear that there has come an increased focus on value for money in the past few years after the financial crises, and the customers need to pay full attention to both efficiency and maintenance cost. The new buzz-words ‘life cycle cost’ have also entered the grab market and lowest price is not necessarily equal to lowest cost anymore.
This has been the strong message towards the customers and in the last couple of years it has resulted in orders for more than ten grabs in Scandinavia and the Baltics for Akerbergs. The biggest being a 60m3 clamshell grab for wood chip handling in Port of Odense in Denmark, and the smallest a couple of 6m3 poly grabs for iron scrap handling in Liepajas Osta in Lithuania.
Akerbergs expects a continuously increasing focus on efficiency throughout the port equipment business, both in relation to time and energy consumption. Together with its principals, Akerbergs does its utmost to meet the requests from customers throughout Scandinavia.
