LIFTON MAGNETS NEOLIFTER 'PR' SERIES

In the series of LIFTON LIFTERS are the Neodymium (NdFeB) permanent magnet based Neolifters PR Series. All LIFTON lifting magnets are simple to operate and almost maintenance free.

High quality and durable materials are used for manufacture of these lifters. The PR series are specifically designed to address the needs of radial and round job lifting. These are designed with an exaggerated V shape to cater to a larger range of diameters of round parts. Consequently, the lifting capacity of the PR range for rounds parts is higher than other lifting magnets.


POINTS TO NOTE

In spite of the excellent properties of LIFTON Lifters, when working with the permanent magnet range a few points must be noted.


SURFACE CORROSION OF WORKPIECE

There is a reduction in the lifting capacity when the surface of the material is painted or coated as the pole plate cannot come in direct contact with the ferrous surface. This distance is called the air-gap. The air-gap size determines the lifting capacity.


SAFETY FACTOR

LIFTON strictly adheres to a safety factor of at least 3:1 for all lifting magnets. While the surface condition i.e. the area of contact is very important in general; a smooth flat surface is good enough. The magnet should always be hung from the centre of the job i.e. used in equilibrium as far as possible.


JOB THICKNESS CHART

The surface condition, temperature, material property of the material to be lifted play just a vital role as the thickness of the job. If there is insufficient thickness of the material, there may be a reduction in overall lifting capacity of the permanent magnet lifter as per the table below.
