What is an Electromagnetic Lifter?{When you energize the pole encircled by coils, it turnsThe magnetic force goingthrough the pole is conditional and directly proportional to the current passed and the number of turns surroundingthe coil.Most scrap yard lifting is serviced by electromagnets which are extremely efficient except in times where non-stoppower supply is disrupted thus causingthe magnetic force to be inactive.A lifting magnet of a permanent kind, true to its name works on permanent magnets that you switch on and off with a lever.It is rare to have a permanent magnetic lifter with a lifting capacity of over5000Lbs.The technology merges the benefits of both, the permanent magnets and electromagnets, putting together the protection of the former with the strength of the latter.Since, permanent electromagnetic lifters workon tiny electrical pulses you simply turn them on/off even without the needof current for maintaining magnetic force. Also, they are more dependablebecause there's no heat caused by moving components.What happens in the event of loss of electrical power?-The permanent magnet is still the same -The load ...
... remains attached, unless you restore the power to deactivate the magnetForceThe flow of current relieson the resistance of the circuit and in case of magnetic circuits; as reluctance is the name for resistance, and you measure it by: theoretically, we can produce maximum force of 225Lbs/sq. Inch, using mild low carbon steels having piles of sufficient size.Porters of pacemakers, beware!Those who have pacemakers installed must always get away from strong magnetic fields.The magnetic fields in case of permanent lifters and permanent electromagnetic lifters are not deep and the load normally absorbs them.However, you should post warnings at the appropriate places. Electric power for an electro Lifting Magnet- permanentThe magnet type and size dictates that Electro lifting magnets of the permanent type are operatedusing standard mains supplies (110-480V) or a 24 Volt battery.However, the dimensions of the magnet that you wishwanttomoveare restricted and the supplier should indicatethe dimension and shapeof the required magnet.{Though the current can attainhigh levels, its life spanis too short, needing no specializecables or fuses.|Although, the current could attainhigh levels, its life spanis very short, needing no fuses or specialcables.Advantages of Lifting Magnets A magnetic lifter has the following advantages: a) superior safety, b) swiftness of handling, c) ease of accessing load, d) saving of space, e) odd shapes are best undertaken using a specially tailored Magnetic Lifter and f) little maintenanceSafety Standard ASME B30.20-2010 should be applied with a minimum safety ratio of 2:1 for the safe use of "close distance magnetic lifters" as ASME standard B30.20-2010 specifies between test load and safe working load (SWL).Manufacturers have varying results that are usually higher.3:1 ratio is followed by Magnetic lifters of permanent natureWhere to buy lifting magnetsMagnetech Industrial Services is your source for lifting magnet sales, repair, and rewind for the metal and scrap industries, railroad yards, and ship yards.A wide range of sizes and configuration is available to meet all your necessities.
