Experience and state-of-the-art technology



Specialisation as a means of designing optimal lifting equipment



More than twenty experienced design engineers specialising in lifting equipment and with expert knowledge in structural analysis, welding and drive technology design the optimal solutions for your needs.

To do so, personal consultations are often required. Our developers work at our various locations around the world, including in your area.

Continuing professional development is very important at AXZION-GKS and all employees receive ongoing training.

Specialists from the certification bodies DEKRA and TÜV, our professional association and renowned suppliers ensure that our knowledge is updated regularly so that we are able to comply with new standards as soon as they are introduced.

New knowledge is communicated to all members of staff and experienced developers train our new employees.

Our developers work with modern computers and the latest software. Designs are created in 3D using SolidWorks and are verified using the integrated FEM software, while structural analyses are carried out using MathCad or RSTAB.


Load changes


The number of load changes is key. The design engineer of a piece of lifting equipment must work with the operator to establish whether DIN EN 13155 “Cranes – Safety – Non-fixed load lifting attachments” may be used or whether the lifting equipment must be constructed in accordance with Eurocode 3 – DIN EN 1993 “Design and construction of steel structures”.

The intensity with which the lifting equipment will be used must be taken into account in order for it to be constructed correctly.


Up to 20,000 load changes



If the lifting equipment being designed is expected to deal with a maximum of 20,000 load changes, EN 13155 “Cranes – Safety – Non-fixed load lifting attachments” is applied in full. This means that the mechanical load-bearing components must meet the following mechanical stability requirements:

I) The dimensions of the lifting equipment must be arranged in such a way that the machinery is able to bear a static load that is three times its load-bearing capacity and hold the load, even if doing so results in permanent changes to its shape.

II) The dimensions of the lifting equipment must be arranged in such a way that it is able to bear a static load that is double its load-bearing capacity without any permanent changes to its shape.

III) A further significant requirement is laid down in paragraph 6 of EN 13155. It states that individually designed and manufactured products must undergo both a design inspection and an individual inspection. With standard products produced in series, the design inspection must be carried out on one or multiple sample products from the production line and the individual inspection must be carried out on each of the manufactured products.

IV) The manufacturer of the lifting equipment must provide evidence that the welding was carried out by personnel qualified to the standard of EN 287-1 or DIN EN ISO 9606-1 “Qualification testing of welders – Fusion welding”. Furthermore, the quality of the welded joints must be verified in accordance with DIN EN ISO 5817 “Evaluation of welded joints”.


DIN EN 13155 does not cover the dangers concerning the mechanical stability of lifting equipment which is intended to undergo more than 20,000 load changes. As a result, it is imperative that lifting equipment designed in accordance with DIN EN 13155 is withdrawn from service as soon as 20,000 load changes have been performed.


Operating temperatures



The designers must be made aware of the operating temperatures. Standard lifting equipment is used in temperatures of between 0 °C and +80 °C.

When used outdoors, temperatures may fall to -20 °C and in some regions of the world, temperatures as low as -40 °C are possible. In such conditions, low-temperature steels are used.

When hot loads are lifted, on the other hand, extremely high operating temperatures may arise and here, special types of steel capable of withstanding such operating conditions must be chosen.


Lifting speed


The lifting equipment must be designed in line with the speed at which the loads will be lifted. In general, the maximum lifting speed is 10 m/sec. To make the loading process quicker, much higher speeds are possible at cargo handling companies (ports, steel works, etc.), for example. These speeds must be communicated to the designers in advance.


Specific operating conditions



Forklift truck

Not all lifting equipment is used with a crane. For example, lifting equipment is often used with a forklift truck.

This results in significantly higher dynamic load conditions. Moreover, the lifting speed is generally much greater than with a normal crane.

The possible use of the lifting equipment with a forklift truck may result in many load changes taking place in very quick succession and it is essential that this is taken into account during the design phase.



The requirements placed on lifting equipment used at sea are particularly stringent and, as a result, the design and production stages are strictly regulated.

The dynamic forces produced by the wind and waves may be enormous, making working at sea dangerous. Lifting equipment used in these conditions must therefore be easy to operate and extremely safe.

By providing us with detailed information on how you wish to use your lifting device, we will be able to design the right equipment for your needs.
