26.8.1 Installation
Installation will vary from simply hanging a portable permanent magnet type of lifter from a correctly sized, free to articulate crane hook, to a more complex operation involving an electro or electropermanent magnetic lifter. For all types, IT IS ESSENTIAL to ensure that the magnetic lifter is only installed on the equipment and for the lifting operations for which it has been selected. In addition:
26.8.1.1 Permanent Magnet Type
Take account of the self weight of the magnetic lifter – it can be significant.
Ensure that the lifting eye of the magnetic lifter correctly engages with the seat of the lifting machine hook and articulates freely with it so that the magnetic lifter hangs level. If necessary use an intermediate lifting accessory such as a shackle.
Ensure that the lifting machine hook can rotate so as to facilitate correct orientation of the magnetic lifter to the load, bearing in mind that this type of magnetic lifter is usually rectangular.
26.8.1.2 Electro and Electro–Permanent Magnet Type
As for permanent magnet types point 1 – 3 inclusive.
Ensure availability of electrical supply (either battery or mains).
Ensure that appropriate electrical safety tests are carried out.
