The right design of your load handling device
The number of load cycles is critical. The designer of a load handling attachment must determine, in cooperation with the user, whether DIN EN 13155 “Cranes – Safety – Loose load handling attachments” can be applied or whether the load handling attachment must be designed in accordance with DIN EN 13001 “Cranes – General design – Part 1: General principles and requirements”.
For a correct design of the load handling attachment, a projection of the intensity of use is thus required. Factors for the design are the “planned service life”, “lifting operations per day” and the “load changes per lifting operation”. Not all load handling attachments are used together with a crane (see also “Lifting speed”).
The right components
Steel, hydraulics, electrical, etc.: Only with good components can a safe and good solution be achieved. We have been working for many years only with the best steel and component suppliers. This always includes complete documentation of all components included in the scope of delivery of a load handling device. This is just as important as the delivered component itself. For all materials used, we require at least an acceptance test certificate 3.1 – according to DIN EN 10204 – from the manufacturer. All material certificates and test reports as well as their proof of use are managed and archived by computer.
The operating conditions of your load handling attachment
The normal load handling attachment is used in a temperature range from -10° C to + 60° C. When used outdoors, temperatures as low as – 20° C can be reached. In some regions of the world, temperatures as low as – 40° C are even possible. In these cases, steels with low temperature resistance are used. When transporting hot loads, on the other hand, very high operating temperatures are possible. Special steels suitable for these operating conditions must be used.
A load handling device must be designed for the lifting speeds that occur. A maximum of 10 m/min is usual. In order to speed up loading processes, much higher speeds are possible, e.g. in handling operations (port, steel mill, etc.), and these must be known at the design stage. An important and widespread application is the use of the load handling device together with a forklift truck.
In combination with a forklift truck, the dynamic loads on the load handling attachment are significantly higher. The lifting speed is usually higher than with a normal crane. Wind and waves as occurring dynamic forces can be enormous.
The requirements for load handling attachments are particularly high when used on the high seas, i.e. offshore. The design and construction are strictly monitored.
Testing and documentation of your load handling attachment
Material and process tests mean additional safety.
Our work is inspected by our own or independent inspectors using the latest testing equipment. All certifications are available. We test during production itself (e.g. magnetic particle testing, dye penetrant testing, ultrasonic testing, notched bar impact testing).
The required final tests are always carried out by a neutral testing institute.
AXZION-GKS works closely and in partnership with the major testing organizations such as TÜV, DEKRA, Lloyd`s Register and DNV GL. Testing is carried out on one of the two in-house test rigs. The facility, which has been located at the Langenfeld site for many years, has a tensile force of 600 tons. At the Neustrelitz site, very large lifting structures with a tensile force of even 1,800 t can be tested.
The load tests are controlled by manual operation or computer-controlled with evaluation. In this way, load handling devices can be tested at rest under absolutely realistic operating conditions.
The documentation is as important as the manufactured product. A complete documentation is therefore always part of the scope of delivery of a load handling device.
The information and scope must correspond to the current status of the LAM, proof of the quality of the components and materials used and of the tests carried out must be included.
With the in-house document management system documents from different sources are combined, managed and archived to one documentation.
The partially automated document management includes a ticket system and a sharing interface that organizes the workflow between customer and manufacturer.
