SPECIAL APPLIACTIONS
GENERAL

TRUNINGER have designed and manufactured numerous magnet systems for particularly difficult or unusual handling applications. Should you have any magnetic handling need, TRUNINGER may have already produced the solution to your needs.
Quick Change System
Quick Change System

This system allows a number of different products to be handled by the same crane. The lower sub- spreaders are detachable, to allow inter-changeability of magnets designed for more than one type of product handling. For example, a Quick Change system could have sub-spreaders for handling single structurals or bundles of structurals or bars, dependant on which lower sub-spreader is utilized on the main upper spreaders.  The Quick Change system shown with lower sub-spreaders for single, structural products handling.  Operator controls the removal and re-placement of the sub-spreaders from the radio controller.  The sub-spreaders are secured to the upper spreaders with twist locks.  Quick Change system shown with lower sub-spreaders for bundles of structural products.

Rail Wheels Magnet

This specialised magnet provides centering into the rail wheels, to ensure solid contact between the magnet and the wheel surface.

Excavator Mounted Magnet

This specialised magnet is mounted on an excavator at one of Spain’s largest steel producers. The magnet system is a Quick Change type, with sub-spreaders to handle reinforcing steel coils, slabs or beams.

Plate Handling Magnet on Fixed Spreader Beam

This specialised magnet system has 175 small round magnets, each one fully controllable from the crane’s host computer. The system is installed on a fully computerized plasma cutting bed at Meyer Werft Shipyard in Papenburg, Germany. The magnet lifting system has been in continuous use on the automatic crane for 10 years. The various sized plates are magnetically picked up as semi-finished products at a reference point. When they are lifted, they are inspected to ensure that only one plate is hanging on the magnets. The plate is then transported to a plasma-cutting machine and placed on its cutting table, according to reference points. Once the cutting of the plate, into a large number of interlocking pieces has been completed, the entire plate (with all of the pieces and the scrap) is picked up in a single lifting operation and placed in a sorting area. Here is where the pieces and scrap are separated from one another. In the meantime, the magnet system can transport another plate to the plasma cutter. Consequently, the magnet crane and the plasma-cutting machine are always working at optimal capacity.

Plate Handling Magnet on Fixed Spreader Beam

This specialised plate handling magnet system is located at Severfield-Reeve Structures, at Dalton in the English county North Yorkshire. Around 1,500 tonnes of steel are processed into customer-specific steel profiles by 336 trained employees at eight production lines every week. Severfield-Reeve Structures is thus the largest steel processor in the UK. This leading position was achieved on the basis of good ideas and state-ofthe- art manufacturing methods. The plates are transported magnetically either to the web or flange profiling machine. The plates are cut into the correct formats, and the surfaces are cleaned for the following welding process as the next step. The beam web and both flanges, which can vary in thickness and dimensions, are placed in the correct position at an assembly station. The first welding line welds the upper side of the three components together, while the underside of the beam is permanently connected in the second welding machine. If necessary, the beam can be turned or even bent in a further process. Then comes the desired surface treatment. In 2003, Severfield-Reeve Structures took yet another strategically significant step and invested in what is undoubtedly the most modern welding equipment in Great Britain. It can handle extraordinary solutions such as welded beams of up to 23 metres in length. Severfield-Reeve Structures ordered a TRUNINGER magnet system for this new production line as well. The multi-functional design of the TRUNINGER magnet beam is what makes the diversified material dimensions at all possible and is an important link in the future-oriented production process at Severfield-Reeve. The magnet system assures the continuous feed of the three basic beam elements, to the automatic welding machine. The magnet system is comprised of a primary spreader beam with five sub-beams. The two outer sub-beams on each side can be moved, while the middle beam is fixed. This arrangement secures the required longitudinal setting of the magnet position, for the various material lengths. Each of the sub-beams is equipped with three rectangular magnets - the two outer magnets are suspended so that they are laterally mobile. The middle magnet, which is installed in a fixed position, can be rotated by 90°.
