INTERESTING FACTS ABOUT TML/TMC MAGNETS FREQUENTLY ASKED QUESTIONS 9. What is the impact of extreme temperature on TML/TMC magnets? Even high temperatures of up to 60°C (140°F) have no impact on the performance of our TML and TMC magnets. At temperatures above 60°C (140°F) or in the event of heat generation near the magnet (e.g. during welding), the integrated high performance permanent magnets may be damaged. For this reason the magnet should be removed from the heat source as quickly as possible. Low temperatures do not decrease the performance of your magnet either since the magnetic molecules align simultaneously in one direction (and thus maintain the magnetic field). Although the magnet slowly loses its lifting power at -150°C (-238°F), the use of TML/TMC magnets at low temperatures must be restricted due to certain components: Components made of aluminum or plastic for example become brittle and may break at a temperature below -30°C (-22°F). The grease does not endure very low temperatures and may become hard. To ensure a long service life and the safety function of your ALFRA magnet, TMC magnets may only be used up to -30°C (-22°F) maximum and TML magnets up to -10°C (14°F) maximum. 10. Why do TML and TMC magnets have different operating temperatures? The Lifting Magnets TML 250, 400 R, 500 and 1000 are equipped with a special safety tab whose proper function may be limited at very low temperatures. The TML 500 is additionally equipped with a special feature–a hydraulic damper. Thanks to the integrated variable damper the user can adjust the recoil energy according to the desired requirements. As the oil inside the damper loses its viscosity with decreasing temperature, the magnet must not be used below -10°C (14°F). TML and TMC models without a safety tab and variable damper may still operate up to -30°C (-22°F). 11. Does the magnet require examination after a certain period of time? Lifting accessories such as our TML magnets must be checked regularly. This includes particularly an annual inspection of the triple safety factor. Maintenance and care of the magnets are subject to country-specific regulations and standards. In Germany regular inspections are prescribed by sec.3, subs.3 of the German Ordinance on Industrial Safety and Health (BetrSichV). The examination of the triple safety factor must be performed once a year by a competent person according to the German Trade Association Regulation BGR 500. The operator is responsible for the adherence to the regular inspection of the magnet. Always observe the regulations in your country. Clamping Magnets such as the TMC 300 must not be used for the lifting or transportation of loads and thus do not require an annual examination. 12. Who is allowed to perform the inspection? According to the Trade Association Regulation 500 (chapter 2.8: sec.3.15), the employer determines the requirements that the person carrying out the inspection must fulfill (‘competent person’). They can be experts such as engineers, machine and crane foremen or specially trained persons provided that they possess adequate knowledge as well as sufficient experience of slings and lifting accessories and are familiar with the relevant national occupational health and safety regulations, trade association regulations and generally accepted rules of technology (e.g. BGR regulations, DIN- EN-standards, DIN-standards, ISO standards). Furthermore, the examination of the triple safety factor for the Lifting Magnet requires a special pull-off unit which is equipped with calibrated test equipment. We would be happy to perform the inspection of your ALFRA lifting accessories for you at our premises. 13. Can loads also be lifted vertically? Due to the innovative ALFRA Magnetic System, the vertical lifting of loads is no longer a problem. In particular, the TML 400 R, 500 and 1000 are excellent devices to lift components vertically. The magnet’s load swivel (also called load hook) is pulled up vertically by means of a flexible soft eye, following the direction of the force action, and lies close to the level housing of the TML magnet. 14. Which forces act during a vertical lift? There are some particularities to note in terms of the vertical lifting of loads. If the load and the magnet surface tilt at an angle other than 0° to horizontal, the load-bearing capacity decreases due to the new alignment of the magnet to the gravity of Earth. As soon as the load is suspended vertically, i.e. at an angle of 90°, friction will be the only effect exerted by the magnet. Depending on the material being lifted this is not more than 10 - 35% of the maximum loadbearing capacity. Further information on the use of TML magnets during pivoting or vertical lifting can be found in the operation manual of your ALFRA magnet. All information and safety instructions contained in the operation manual must be closely observed. 15. Are the magnets only suitable for the lifting of loads? The wide range of ALFRA magnets includes a multitude of applications that go far beyond the lifting of loads. For example, TML magnets are ideally suited to shearing loads. Moreover, magnets made by ALFRA also represent the ideal tools to facilitate your work if you want to align, position or join ferromagnetic workpieces. 185
