Shopping tips

The lifter needs no battery, accumulator, or cable, it works fully mechanically. Activation of the field occurs by turning the hand lever 180 degrees. This guarantees full work safety even in case of sudden power failure in the hall.
The nominal capacity of the lifter (e.g., 1000 kg) is measured in ideal conditions: on smooth and thick steel. Force is affected by material thickness (the thinner, the weaker it holds - magnetic saturation occurs). Always choose a lifter with power reserve, checking the thickness table for a specific load.
The lower part design allows stable gripping of cylindrical and flat elements. This enables universal lifting of both flat sheets and round materials with one device. For shafts, a different weight limit applies than for flat sheets - see rating plate.
The device must withstand a load three times greater than nominal during break tests. It gives a large safety margin in case of unforeseen dynamic forces or vibrations. Despite this, staying under a hanging load is strictly forbidden.
The key to long life is caring for the working surface (magnetic foot). Any dents or stuck filings increase the air gap and weaken capacity. Protect the device from moisture and strong mechanical impacts.

Advantages as well as disadvantages of neodymium magnets.

Apart from their notable magnetic energy, neodymium magnets have these key benefits:

  • They retain attractive force for around ten years – the loss is just ~1% (according to analyses),
  • They maintain their magnetic properties even under strong external field,
  • A magnet with a metallic silver surface looks better,
  • Magnetic induction on the working layer of the magnet turns out to be strong,
  • Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling operation at temperatures reaching 230°C and above...
  • Thanks to the option of free forming and adaptation to specialized requirements, NdFeB magnets can be created in a broad palette of geometric configurations, which amplifies use scope,
  • Wide application in innovative solutions – they are used in magnetic memories, electromotive mechanisms, medical devices, and multitasking production systems.
  • Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which enables their usage in miniature devices

Drawbacks and weaknesses of neodymium magnets: tips and applications.

  • Brittleness is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a steel housing, which not only protects them against impacts but also raises their durability
  • Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
  • Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material protecting against moisture
  • We recommend casing - magnetic mechanism, due to difficulties in producing threads inside the magnet and complicated forms.
  • Potential hazard to health – tiny shards of magnets are risky, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Additionally, tiny parts of these products are able to disrupt the diagnostic process medical in case of swallowing.
  • Due to complex production process, their price exceeds standard values,

Breakaway strength of the magnet in ideal conditionswhat it depends on?

Breakaway force was determined for the most favorable conditions, taking into account:

  • using a sheet made of high-permeability steel, serving as a ideal flux conductor
  • with a cross-section no less than 10 mm
  • with an ideally smooth touching surface
  • without any air gap between the magnet and steel
  • for force applied at a right angle (pull-off, not shear)
  • in neutral thermal conditions

Determinants of lifting force in real conditions

In real-world applications, the actual lifting capacity depends on many variables, presented from the most important:

  • Clearance – the presence of foreign body (paint, tape, gap) interrupts the magnetic circuit, which lowers capacity steeply (even by 50% at 0.5 mm).
  • Load vector – highest force is obtained only during perpendicular pulling. The resistance to sliding of the magnet along the surface is usually many times smaller (approx. 1/5 of the lifting capacity).
  • Plate thickness – insufficiently thick steel does not accept the full field, causing part of the flux to be escaped into the air.
  • Material type – ideal substrate is pure iron steel. Cast iron may generate lower lifting capacity.
  • Surface finish – full contact is obtained only on polished steel. Any scratches and bumps reduce the real contact area, reducing force.
  • Operating temperature – NdFeB sinters have a sensitivity to temperature. At higher temperatures they lose power, and in frost they can be stronger (up to a certain limit).

* Lifting capacity was determined with the use of a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, whereas under shearing force the lifting capacity is smaller. Additionally, even a slight gap {between} the magnet and the plate reduces the lifting capacity.

H&S for magnets

Bone fractures

Watch your fingers. Two powerful magnets will snap together instantly with a force of massive weight, crushing anything in their path. Exercise extreme caution!

Conscious usage

Before use, check safety instructions. Uncontrolled attraction can destroy the magnet or hurt your hand. Be predictive.

Nickel coating and allergies

Medical facts indicate that the nickel plating (the usual finish) is a common allergen. For allergy sufferers, prevent direct skin contact and select coated magnets.

Implant safety

Medical warning: Neodymium magnets can turn off heart devices and defibrillators. Do not approach if you have electronic implants.

Fire warning

Mechanical processing of neodymium magnets carries a risk of fire risk. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.

GPS and phone interference

Remember: neodymium magnets produce a field that confuses precision electronics. Keep a separation from your mobile, tablet, and navigation systems.

Beware of splinters

NdFeB magnets are sintered ceramics, meaning they are prone to chipping. Clashing of two magnets will cause them breaking into small pieces.

Adults only

These products are not suitable for play. Eating several magnets may result in them pinching intestinal walls, which constitutes a severe health hazard and necessitates urgent medical intervention.

Data carriers

Do not bring magnets near a purse, laptop, or TV. The magnetism can permanently damage these devices and erase data from cards.

Maximum temperature

Control the heat. Heating the magnet to high heat will destroy its properties and strength.
