TPM TPM permanent lifting magnets are ideal tools for easy, quick and economical transport of heavy objects made from ferro-magnetic material. Typical operating areas are workshops and warehouses, loading and unloading of machines as well as construction of jigs and fixtures. 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. 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. 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 **Maximum lifting capacity is achieved by using mild steels with the noted minimum thickness. Mild steel st37 - Fe 360 to BS EN 10 025 1990 (DIN 17100) *The TPM20 is a brand new magnet that is due to be launched SPRING 2009. Call our sales team for further details.

THM - Magnetic Claw The THM manual magnetic claws are used for manually transporting steel sheets horizontally and vertically. They can also be used for lifting plates from racks, pulling sheets out of shelving and transporting almost any steel plates that are magnetic. These clamps are capable of carrying plate with a thickness of 1 - 5 mm and are totally maintenance free. They operate by simply placing the claw on to the material. To release the claw the operator must press down on the handle which activates a cam that releases the magnet. NB: The surface of the plate must be free of oil, grease or any other liquid to ensure safe transport. *Measured at a safety factor 2:1 on bright drawn material ST 37 k Product Code Lifting Capacity (kgs*) Pulling Capacity (kgs) Width (mm) Length (mm) Height (mm) Weight (kgs) Price £ (ex VAT) THM 120 120 70 84 140 172 1.2 £219.38 THM 170 170 100 116 140 172 1.7 £277.50 Please call us on (01953) 889998 for more information, including pricing and available discounts.
