Merchant bars

TRUNINGER magnet systems do not only save space, but also a lot of time! Our magnetic grippers are carefully tailored to your product range, your processes and your crane. This results in fine tuned magnet systems covering transport of complete bundles, loose bars or individual pieces, whatever the task may be.

Applications

Merchant bars are handled mainly in rolling mills and steel plants. In addition, our market-leading magnetic lifting systems are used in steel distribution to pick bars and load them onto trucks, railway wagons, or ships.

Transporting bundles of bars in steel mills

Tough and rugged – steel mill applications

In steel mills, TRUNINGER magnet systems cover a wide range of transport tasks for bars.

Specific features for such applications include robust spreader beam construction and resilient magnet design, also for use on hot material up to 600˚C.

Applications

Typical applications are internal handling processes within steel works.

Steel bars in a non-stop production line need to be removed continuously and reliably while shipped out at the end of the line in the dispatch area.

Advantages of magnet systems

Bar bundles of different lengths can be carried thanks to a flexible spreader beam design
Individual control of the magnets enables almost any size of bar to be carried and considerably improves versatility
No aisles required between stacks
Heat-resistant magnets make it possible to handle hot material up to 600°C (see ‘Load temperature > 120°C’ document)
Easy control of the system from the crane cabin allows to realize high crane speeds

Your benefits

Fewer accidents and increased safety
More compact storage
Faster handling speed
Lower labour costs

Handling of bar bundles at steel distributors

Faster material handling in the warehouse

A correctly designed magnet system enables fast and safe handling of merchant bars in the warehouse reception as well as storage and dispatch area. You do not only save space, but lots of time as well.

Magnets, when properly guided, allow the load to be approached, picked, unloaded from truck and placed to storage, quickly and reliably.

Such TRUNINGER magnets' poles adapt to the load. Wide pole surfaces are used in the reception area, where larger formats or bundles are typically handled.

Safe transport of material to the storage location

Magnet systems pave the way for denser packing of your warehouse, which results in shorter average crane travel and therefore time saved. Material can be stored efficiently:

Between uprights
In stacking cradles
In cassettes

Storing between uprights

Storing between uprights is a simple concept which ensures maximum stacking height and high storage density.
A perfect field of application for magnets as they require

No dangerous climbing on high stacks
No timber spacers between bundles
No presence of people in material handling zone
No manual work on sharp-edged material

Storage in stacking cradles

Cradle carriers on the magnet spreader beam enable quick loading of bundles into the stacking cradles, mechanical transport of the cradle itself as well as fast order picking of individual bars – and all with the same system. Even a highly diversified warehouse can thus be managed efficiently.

Storage in cassettes

A cassette storage system supports fast, efficient operations within a limited footprint. It enables high levels of flexibility and productivity for handling and picking small to medium quantities and fast-moving products.

For moving material in and out of the cassettes, TRUNINGER offers magnet systems capable to handle both, bundles and single bars as well.

TRUNINGER magnets and spreader beams can be used universally in different areas of your warehouse and boost your material flow with high levels of safety and availability.

Customer order picking

Fast, flexible and efficient commissioning

A properly designed magnet system enables fast and reliable material flow from goods reception to storage to dispatch areas. You do not only save space, but lots of time as well.

For moving material in and out of stock, TRUNINGER offers versatile magnet systems capable to handle bundles as well as single bars.

Adjustable magnetic grippers

Magnets with variable pole geometry are ideal to feed cutting or machining lines and order picking stations.

Using a retractable anchor system, the magnet poles can be adapted to match the load.

With the anchors extended, individual bars or smaller quantities of material can be picked with ease.

Extended anchors also allow quick and easy access to individual bars located in the cassette's corner.

Dispatch area

In the dispatch area, highly flexible magnet systems are needed. The enormous number of different steel bar products with various shapes and dimensions, plus a wide variety of customer-specific bundles, requires a versatile magnet system suitable to cover many different handling task.

TRUNINGER magnets and spreader beams can be used universally in different areas of your warehouse and boost your material flow with high levels of safety and availability.

Features

Retractable poles simplify transport of bundles and singles
Cradle carriers allow separation of same products in minimum space
Swivelling magnets adapt to different load widths
Finger poles prevent the load from rolling off
Fine control of magnet lifting force for fast order picking
Almost complete removal of residual magnetism (< 2mT)
