The right design of your load-bearing equipment
Designing a load-bearing device
The number of load changes is crucial. The designer of a load-bearing device must, in cooperation with the user, determine whether DIN EN 13155 „Cranes – Safety – Loose load-bearing devices“ can be used or whether the design of the load-bearing devices must be done according to DIN EN 13001 „Cranes – Construction in General – Part 1: General principles and requirements“. A projection of the usage intensity is therefore required for a correct design of the load-bearing device. Factors for the design are the „Planned service life“, „lifting operations per day“ and the „load changes per lifting operation“. Not all load lifting devices are used together with a crane (see „Lifting speed“).
The right components
Steel, hydraulics, electric, etc .: A safe and good solution can only be manufactured with good components. We have only worked together with the best steel and construction steel suppliers for many years. This always includes the complete documentation of all components in the scope of delivery for load lifting devices. This is just as important as the delivered assembly itself. The manufacturer requires at least one inspection test certificate 3.1 – according to DIN EN 10204 – for all materials used. All material certificates and test reports as well as their cross-references are managed or archived by our IT department.
The operating conditions of your load-bearing device
The normal load-bearing device is used in a temperature range of -10° C to +60° C. When used outdoors, temperatures down to – 20 ° C can be reached. In some regions of the world, even down to – 40° C is possible. In this case, low-temperature steels are used. When transporting hot loads, however, very high application temperatures are possible. Special steels have to be used here which are suitable for these conditions of use.
A load lifting device must be designed for the lifting speeds that occur. Usually max. 10 m/min. In order to speed up the loading process, significantly higher speeds are possible, for example, in cargo shipment companies (ports, steelworks, etc.), which must be known during the design. An important and widespread use is the use of the load lifting devices together with a forklift truck. Here, the dynamic loads of the load lifting devices are significantly higher. The lifting speed is usually much higher than with a normal crane. Wind and waves occurring as dynamic forces can be enormous. The requirements for load-bearing equipment are particularly high when used on the high seas, i.e. offshore. Construction design and execution are strictly monitored.
Checking and documentation of your load-bearing equipment
Material and process tests mean additional safety. Our work is checked by our own or independent auditors using the latest test equipment. All certifications are available. During production, we do our own inspections (e.g. magnetic powder testing, dye penetration testing, ultrasonic testing, notch impact bending test). The required final tests are always carried out by a neutral test institute.
AXZION-GKS works closely and in partnership with major testing organisations such as TÜV, DEKRA, Lloyd`s Register and DNV GL. Testing is done on one of the two in-house test benches. The system, which has been located at Langenfeld for many years, has a tensile pulling force of 600 tonnes. At the Neustrelitz site, very large lifting structures can be tested with a tensile force of up to 1,800 tonnes. The load tests are done by manual operation or computer-controlled with analysis. In this way, load-bearing devices can be tested quietly under absolutely realistic operating conditions.
The documentation is as important as the manufactured product. Complete documentation is always included in the scope of delivery of a load-bearing device. The information and the scope must correspond to the current state of the Lifting Equipment and must include the proof of the quality of the components and materials used and the tests carried out.
Documents from various sources are combined, documented and archived with the in-house document management system. The partially automated document management includes a ticket system and a sharing interface, which organises the workflow between the customer and the manufacturer.
