The magnetic lifter works based on powerful neodymium magnets and does not require any external power supply. Switching the magnet on and off is done using a simple lever equipped with a safety lock. This is a safe solution because the magnet will not drop the load upon mains voltage loss.
The nominal capacity of the lifter (e.g., 1000.00 kg) is measured in ideal conditions: on smooth and thick steel. In reality, lifting capacity depends on three factors: sheet thickness, air gap, and material type. When selecting a lifter, familiarize yourself with the capacity chart (thickness table) and maintain a safety margin.
Thanks to the specially profiled V-type foot, safe lifting of pipes, shafts, and rods is possible. This enables universal lifting of both flat sheets and round materials with one device. However, remember that capacity for round elements is usually 50% lower than for flat ones (check specification).
Our lifters have a high safety factor of 3:1 or 3.5:1 (depending on model). It gives a large safety margin in case of unforeseen dynamic forces or vibrations. Always observe safety rules during vertical transport, regardless of safeguards.
The key to long life is caring for the working surface (magnetic foot). Mechanical damage to the foot can drastically reduce grip force, creating a hazard. We recommend periodic technical inspections (minimum once a year) at an authorized service center.

Strengths and weaknesses of rare earth magnets.

Pros

Apart from their superior holding force, neodymium magnets have these key benefits:
  • They do not lose magnetism, even during nearly ten years – the drop in power is only ~1% (based on measurements),
  • They show high resistance to demagnetization induced by presence of other magnetic fields,
  • By applying a decorative coating of silver, the element presents an aesthetic look,
  • They feature high magnetic induction at the operating surface, which affects their effectiveness,
  • Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
  • Thanks to modularity in shaping and the ability to modify to specific needs,
  • Universal use in innovative solutions – they serve a role in data components, electric drive systems, precision medical tools, also modern systems.
  • Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,

Cons

What to avoid - cons of neodymium magnets: tips and applications.
  • Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a steel housing, which not only protects them against impacts but also increases their durability
  • When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
  • When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation and corrosion.
  • Limited possibility of creating threads in the magnet and complex shapes - preferred is cover - magnetic holder.
  • Health risk related to microscopic parts of magnets can be dangerous, in case of ingestion, which is particularly important in the context of child health protection. Furthermore, small components of these magnets are able to be problematic in diagnostics medical in case of swallowing.
  • With budget limitations the cost of neodymium magnets is economically unviable,

Lifting parameters

Optimal lifting capacity of a neodymium magnet – what it depends on?

Holding force of 1000.00 kg is a theoretical maximum value performed under specific, ideal conditions:
  • on a block made of mild steel, optimally conducting the magnetic flux
  • whose thickness is min. 10 mm
  • with an polished touching surface
  • with direct contact (without paint)
  • during detachment in a direction vertical to the mounting surface
  • at temperature approx. 20 degrees Celsius

Key elements affecting lifting force

In real-world applications, the real power is determined by a number of factors, ranked from crucial:
  • Distance – the presence of any layer (paint, tape, gap) interrupts the magnetic circuit, which reduces capacity steeply (even by 50% at 0.5 mm).
  • Angle of force application – highest force is available only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is typically several times lower (approx. 1/5 of the lifting capacity).
  • Substrate thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
  • Metal type – different alloys attracts identically. High carbon content weaken the attraction effect.
  • Surface finish – full contact is obtained only on polished steel. Rough texture create air cushions, reducing force.
  • Heat – neodymium magnets have a sensitivity to temperature. When it is hot they are weaker, and at low temperatures gain strength (up to a certain limit).

Lifting capacity was determined by applying a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular pulling force, whereas under parallel forces the load capacity is reduced by as much as 5 times. Moreover, even a small distance between the magnet and the plate decreases the lifting capacity.

H&S for magnets
Product not for children

Absolutely keep magnets away from children. Ingestion danger is high, and the consequences of magnets connecting inside the body are life-threatening.

Risk of cracking

NdFeB magnets are sintered ceramics, meaning they are fragile like glass. Clashing of two magnets will cause them breaking into small pieces.

Data carriers

Equipment safety: Neodymium magnets can damage payment cards and delicate electronics (heart implants, hearing aids, mechanical watches).

Nickel allergy

It is widely known that nickel (standard magnet coating) is a strong allergen. If your skin reacts to metals, avoid direct skin contact or select versions in plastic housing.

Heat sensitivity

Do not overheat. Neodymium magnets are susceptible to temperature. If you need resistance above 80°C, ask us about HT versions (H, SH, UH).

Implant safety

Health Alert: Strong magnets can turn off pacemakers and defibrillators. Do not approach if you have medical devices.

Keep away from electronics

Be aware: neodymium magnets generate a field that confuses sensitive sensors. Keep a safe distance from your mobile, device, and navigation systems.

Hand protection

Watch your fingers. Two large magnets will join immediately with a force of massive weight, destroying anything in their path. Exercise extreme caution!

Conscious usage

Handle magnets consciously. Their huge power can shock even professionals. Stay alert and respect their power.

Dust explosion hazard

Fire hazard: Neodymium dust is highly flammable. Do not process magnets without safety gear as this may cause fire.

Important! Details about hazards in the article: Safety of working with magnets.
