IMA’s permanent magnetic lifters are made with Neodymium magnets of high magnetic strength. They are completely self-contained and do not need to be connected to any source of electrical energy.
In order to activate the Lifter, you must push the handle to the right approximately 100 degrees and lock it with the security latch, which blocks it during the working period.
Format and characteristics:
The practical and efficient design of Ima’s Permanent magnet lifter, allows any type of metallic objects to be handled, whether they have flat or round surfaces.
The Lifter has a safety lever which avoids accidental demagnetisation. These Permanent lifters are the answer to the handling of ferrous materials at an exceptionally low cost, without any installation or maintenance cost whatsoever. Also, thanks to its low weight, it can be incorporated in any type of crane mechanism.
Objetcs to be lifted:
IMA Magnetic Lifters are supplied in 6 different models: IMA 100 / 250 / 500 / 1000 / 2000 / 3000 indicating the maximum kg weight the models can lift in the case of flat objects:
|Code||Weight (kg)||A (mm)||B (mm)||H (mm)||W (mm)||L (mm)||X (mm)||Y (mm)||Max load (kg)|
|flat pieces||tubular parts|
However, it should be taken into account that the characteristics of objects to be lifted can affect the capacity of the lifter.
Maximum forcé to be obtained under optimum conditions, using a plate of ST-37 iron, sufficiently thick (≥30-80mm) and a smooth, flat surface.
Four basic factors which affect the magnetic pull of a magnetic lifter:
|Loading Material||Weight (kg)|
|Unalloyed Steel 0.1-0.3%C||100%|
|Unalloyed Steel 0.4-0.5%C||90%|
|Alloyed steel F-522||80-90%|
|Fray cast iron||50-60%|
|F-522 Tempered steel at 55-60 HRc||40-50%|
|Stainless Austenitic Steel||0%|
|Brass; Aluminium; Copper||0%|
