Sheet

In order to handle sheets gently and safely, for single sheets or packs, the magnets must have a deep magnetic field that can also be fine controlled.

It ensures that the resulting lifting forces penetrate a large area of the material precisely dosed. Pressure marks and edge dents which are detrimental to the sheets' quality are thus prevented, and desired quantities can be selected efficiently and moved safely.

 

Applications

TRUNINGER manufactures custom-made magnetic lifting systems tailored for storing and order picking in steel warehouses. We also offer technical solutions for the following processes within the warehouse or plant

Transporting sheet packs

Handling quick and gentle

Well designed magnets provide finely dosed lifting forces distributed over a large contact area. On one hand, this prevents pressure marks and edge damages impairing the sheet quality. On the other hand, partial quantities can efficiently be selected and safely be handled.

And, of course, the magnet system can be used to transport single sheets as well as sheet packs. Packs allow to handle significantly larger quantities per lift compared to loose stacks of sheets.

For safe transport of sheet packs, deep penetration of the magnetic field into the packs is required. TRUNINGER provides magnet systems specialized for sheet packs fitted with magnets designed for this purpose. However, the magnetic field may not penetrate a pack down to the lowest sheet; some of the sheets will be carried mechanically by the strapping.
 

Important: Highly adaptable!

Incoming material handling, internal transport, order picking, and dispatch procedures require magnet systems to be highly adaptable to the material to be handled and to the material flow.

It is essential that the distances between the magnets are adapted to the lengths of the sheets so that any deflection can be kept to a minimum and the distribution of the load between the magnets can be optimised. Only in this way can safe transport of the material be guaranteed.

Being able to rotate the magnet beam while it is carrying its load allows packs to be lined up in any direction on lorries or in the warehouse.
 

Magnet systems for sheet packs

These are the advantages of using a magnetic system for handling packages of sheet metal.
 

Their advantages

  • Can carry small, medium and large formats, plus special lengths
  • No need for chains or mechanical grippers
  • Packs can be rotated by means of a load slewing device on the spreader beam
  • Picking sheets straight out of opened packs saves time
 

Your benefit

  • One system for all formats—one size fits all!
  • No loss of material quality during handling
  • Fewer accidents and increased safety
  • Faster handling speed

TRUNINGER design features

TRUNINGER designs and manufactures lifting magnet systems for handling sheet packs of all sizes.

  • Multi-purpose spreader beams and correctly configured magnet design are key features of the TRUNINGER magnet systems for sheet transport.
  • The magnet beam design is adapted to the relevant material lengths. Three types of beam are used: fixed beams with movable magnet groups (see figure 1), extremely compact active telescopes (see figure 2) and lightweight passive telescopes (see figure 3).
  • The magnet controller enables simple motorised movement of the magnets, allowing them to be positioned correctly to suit differing material lengths. This minimises any load deflection and guarantees safe transport.
  •  Load slewing device allows the spreader beam and load to be rotated in order to align the packs with the material flow (see figure 1).
  • With TRUNINGER magnet systems the lifting force can be finely adjusted, thus enabling even thin steel sheets to be separated.

Features

  • Slewing device eases loading and unloading of trucks
  • Slewing magnets adapt to different plate widths
  • Stacking cradles allow compact separating of each product in dedicated compartments
  • Fine control of magnet lifting force for fast picking of partial quantities
