Key Features

  • 6 sizes 100 kg to 2,000 kg capacities
  • Compact design of the units for a large number of applications
  • The load is not affected mechanically which allows lifting of flat as well as round material
  • The permanent magnets do not require electric energy and will leave only minor residual magnetism on the the material after use.
  • The magnets are activated/deactivated easily by turning a locking lever
Delivery Options

TPM permanent lifting magnets are ideal tools for easy, quick and economical transport of
heavy objects

Made from a ferromagnetic material. Typical operating areas are workshops and warehouses, loading and unloading of machines as well as the construction of jigs and fixtures.

The compact design of the units for a large number of applications. The load is not affected mechanically which allows lifting of flat as well as round material. The efficient magnet body provides a strong lifting capacity at the low dead weight.

The permanent magnets do not require electric energy and will leave only minor residual magnetism on the
the material after use.

The magnets are activated/deactivated easily by turning a locking lever. Inactivated condition, the hand lever will
be safely locked and thus prevent unintended demagnetising. The selection of the appropriate magnet model should be made under consideration of the varying conditions of the contact surface, kind of material alloy and plate thickness/bar diameter (see table).
 
Factors that reduce the magnetic clamping force:-
Air gap: High magnetic forces created by the TPM allow the magnet to clamp components through the air gap, however, air gaps will reduce the magnetic performance as they provide a barrier between
the contact surfaces. Air gaps
occur in a number of different ways such as paint, dust and heavy mill scale. Poorly machined surfaces also constitute an air gap. Please down rate the magnet capacity in accordance with the adhesive force/air gap diagram below.
 
Material thickness: If the TPM is used to lift plates thinner than the recommended minimum thickness, the clamping forces will be significantly reduced. Performance curves can be identified in conjunction with the adhesive force/flat thickness diagram below:
 
Contact area: Full lifting capacity can only be achieved when the magnet has a full contact area with the component being lifted. If the contact surface has holes in or is uneven then the performance will be affected accordingly. Always carry out a trial lift in these circumstances to establish correct lifting before transporting the load.
 
Material type: Certain materials have different abilities to carry magnetism. For materials other than mild steel a reduction factor must be applied in order to calculate the effective clamping force.

Typical values:
Ferrous alloy steels 0.8
High carbon steels 0.7
Cast iron 0.55
Examples of reduced SWL:
Mild steel 500g
Cast iron 500 kg x 0.55 = 275 kg

In order to achieve maximum capacity, the contact surface should be bright and free from dirt, oil, grease, scale, corrosion, paint etc.
