- Yale "TPM" Permanent Lifting Magnet - Range from 100kg to 3000kg
The Yale TPM series of load lifting magnets are available in the following capacities; 100kg, 300kg, 500kg, 800kg, 1000kg & 2000kg.
Yale TPM load lifting magnets are ideal tools for easy, quick and thus economical transport of heavy objects made from ferro-magnetic material.
Capacities and Reductions
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 (see below and 'Capacity Reductions' Tab above).
Note: In order to achieve a maximum capacity, the contact surface should be bright and free from dirt, oil, grease, scale, corrosion, paint etc.
Magnet Features
- Typical operating areas are workshops and warehouses, loading and unloading of machines as well as construction of jigs and fixtures.
- Small dimensions of the units provide a wide number of additional applications.
- The load is not affected mechanically which allows lifting of flat as well as round material.
- The efficient magnet body provides strong lifting capacity at low dead weight.
- The permanent magnets do not require electric energy and will present only minor residual magnetism after switching off.
- Switching ON and OFF operations are easily accomplished by turning a locking lever.
- In activated condition the hand lever will be safely locked and thus prevent unintended demagnetising.

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 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 500kg x 0.55 = 275kgs
